Abstract
A selective call receiver (30) receives personal messages and information services. A memory (44) stores the personal messages and the database messages. A display (42) displays the plurality of screens. The user can display screens manually through activation of user input controls (40). Alternatively, the user can display selected screens in a quick access or quick view mode by placing operation of the receiver (30) under the control of a quick view controller (60) coupled to the database portion of memory (48). The user can selectively flag a screen (fig. 9) or trigger a numeric field of a screen (fig. 16). When database messages are received which update a flagged screen or triggered screen, the flagged or triggered screen automatically becomes one of the selected screens for display in the quick view mode.
Description
.~_ X2112808 METHOD AND APPARATUS FOR QUICK ACCESS TO SELECTED
UPDATED INfFORMATION IN A SELECTIVE CALL RECEIVER
20 Field of the Invention This invention relates in general to selective call receivers, and in particular to selective call receivers for receiving information services.
Background of the Invention Selective call receivers are radio frequency receivers which selectively receive messages. Conventionally, a selective call receiver examines a selective call signal to determine whether the receiver has been addressed. When an address assigned to the receiver is detected, the selective call receiver decodes a selective call message. The user is alerted that a message has been received and the message can thereafter be presented, either as a voice message or a numeric or alphanumeric displayed message. The message may be displayed on a conventional display such as a liquid B
' WO 93/23930 PCT/US93/03900 .-~", 1.1.28D8 2 crystal display (LCD). It is desirable that selective call receivers be portable and, consequently, most selective call receivers have LCD's of limited size. Additionally, most selectivE; call receivers have limited room for user input controls.
More recently, users of selective call receivers desire additional features, such as reception of information services, whi:Le maintaining the desire for small portable receivers. Information services are services which provide regularly updated messages, such as news services (UPI), financial services (Dow Jones Stock Reports), or sports services. One such information services selective call system is described in United States Patent No. 4,895,491.
A user can subscribe to several information services and receive information on many topics. Each topic may consist of several screens (i.e. information capable of being displayed on the LCD at one time). To view a screen of information, the user manipulates the limited number of user input controls to reach the screen. This manipulation could consist of numerous activations of user controls.
The information is updated regularly by selective call messages comprising update information. If the user is alerted each time one of the screens is updated, it is likely that the user would be continuously alerted.
Conversely, if the user is not alerted when a screen is updated, the user would be unaware of changes in information which are of importance to the user. Further, if the user elects to be alerted of an update and misses the alert either by having the alert turned off or not having the receiver on or near the user's person when the alert is activated, the user has no way of knowing that an update of information has occurred.
Additionally, access to updated information poses the ' same difficulties as access to any screen of information.
It is undesirable for the user to be forced to continuously Vlc~""n3/23930 PCT/US93/03900 manipulate the user controls to select screens of interest in order to view their updated information.
Thus, what is needed is a method and apparatus for notifying the user of selected updates of information and for allowing a user quick access to the screen or screens of updated information.
Summary of the Invention In carrying out the objects of the invention in one form there is provided a selective call receiver comprising a receiver means for receiving update information, a display means for displaying a screen of information, and a user selectable means for programming trigger boundaries associated with a portion of the screen of information.
The selective call receiver also comprises an alert means for providing an alert in response to the update information received comprising information outside the trigger boundaries, and a quick view means for adding the screen of information comprising the update information to a list of screens if the update information comprises information outside the trigger boundaries. The user selectable means further permits direct user access to a screen of information if the screen of information is on the list of screens.
In another form, the present invention provides a selective call. receiver for receiving selective call messages. The: selective call receiver comprises a receiving means for receiving selective call messages comprising update messages, a memory means for storing a plurality of screens, a user input means for receiving input signals from a plurality of user keys in response to user activation of the user keys, and a display means for displaying the: plurality of screens to a user. A first control means is coupled to the memory means and the display means for maintaining a list of screens comprising 2 ~ ~ ~ 4 PC'f/US93/03900:--~
user selected ones of the plurality of screens and for permitting the user to display one of the plurality of screens with a minimal number of user activations of the user keys if the one of the plurality of screens is on the list of screens. A second control means for maintaining the plurality of screens comprises a flagging means coupled to the user input means for flagging one of the plurality of screens in response to user activation of the user keys, an updating means for updating the plurality of screens in response to the update messages, a first determining means for determining whether an update message updates a flagged one of the plurality of screens, and a signalling means coupled to the first control means for signalling the first control means to add an updated one of the plurality of screens to the list of screens if the first determining means determines that the updated one of the plurality of screens is a flagged one of the plurality of screens.

Detailed Description of the Invention Referring to FIG. 1, a selective call system in accordance with a preferred embodiment of the present invention transmits two types of signals: information services signals and personal message signals. As is well WO 93/23930 ~ ~ ~ ~~ ~ ~ ~ 6 PCT/US93/03900,.-..
known to those skilled in the art, an originator of a personal selective call message inputs message information via a telephone input 10 to a paging terminal 12. The paging terminal 12 comprises an encoder 14 for encoding the message information into selective call signals and a transmitter 16 for transmitting the selective call signals via an antenna 18.
Information services signals are derived from information services 20 which compile financial, sports, news, etc. information and forward the information to a data center 22. The data center 22 compiles the information provided by the information services 20 into appropriate messages which are provided to a paging terminal 12' for transmission as selective call signals therefrom. The paging terminal 12' similarly comprises an encoder 14' a transmitter 16' and an antenna 18'.
Thus, it can be seen that a selective call system in accordance with the preferred embodiment of the present invention broadcasts signals comprising personal message selective call messages and information services selective call messages for reception by a receiver 30. The receiver receives the selective call signals at an antenna 32 which generates electrical signals in response to the radio frequency signals received and forwards the signals to 25 receiver circuitry 34 for demodulation. The demodulated signal is provided to a microprocessor 36 for processing thereby. The microprocessor 36 is coupled to an alert device 38, user input controls 40, and a display 42 for interfacing with a user of the selective call receiver 30.
30 Additionally, the microprocessor 36 is coupled to an external random excess memory (RAM) 44 for storing information therein and for retrieving information therefrom. In accordance with the preferred embodiment of the present invention, the external RAM 44 has designated portions for storing personal messages 46 and for storing databases 48. The databases are stored in a portion of the r 2112808 ~ .
external RAM 48 in a manner which allows a user to access the information services data stored therein.
When a selective call signal is received and demodulated b:y the receiver circuitry 34, address detection block 50 of tl'ze microprocessor 36 examines the selective call signal to determine if an address assigned to the microprocessor is present within the signal. When an address assigned to the selective call receiver 30 is detected by the address detection block 50, a controller 52 is signaled to start a decoder block 54 decoding the received and demodulated selective call signal. The decoded signal is provided from the decoder block 54 to the controller 52 for processing thereby. The controller 52 stores the de<:oded selective call message in portions 46, 48 of the external RAM 44. The controller 52 thereafter provides a signal to the alert device 38 to alert the user that a select~_ve call message has been received. Upon manipulation of the user input control 40 by the user, the controller wi7_1 provide the decoded selective call message to a display driver 56 for generation of a user readable display upon t:he display 42. A clock 58 is coupled to the controller 52 to provide conventional clocking functions allowing for proper operation of the controller 52 and the microprocessor 36.
The selective call receiver 30 is user operable in three modes in accordance with the preferred embodiment of the present irwention: a personal message mode, a database mode, and a qu~.ick view mode. When operating in the personal message mode, the selective call receiver can function as a conventional pager whereby the user can manipulate the: user input controls 40 to select and read various personal messages stored in the personal message portion 46 of the RAM 44. During database mode operation, the user can manipulate the user input controls 40 to select and read various screens of the databases stored in the database portion 48 of the RAM 44.
s WO 93/23930 PCT/US93/03900,.,,, ~1,~.2808 8 In accordance with the preferred embodiment of the present invention, quick view mode operation is a mode of operation for allowing a user quick access to selected screens under the control of a quick view controller 60.
The quick view controller 60 is coupled to the controller 52 for controlling the operation of the microprocessor 36 when the user places the selective call receiver 30 into the quick view operation mode. The quick view operation mode involves an automatic quick view mode wherein the quick view controller 60 automatically retrieves user selected screens from the database 48 and provides those screens sequentially to the display driver 56 for display upon the disp:Lay 42 or a manual quick view mode wherein selected screens may be user selectably retrieved from the memory 48 for display without the user having to navigate through a database to the screen. The clock 58 is coupled to the quick 'view controller 60 for controlling the amount of time that ~sach of the user selective screens are displayed upon the display 42.
Referring next to FIG. 2, a preferred embodiment of the multi-function selective call receiver 30 of FIG. 1 is depicted. The user input controls 40 (FIG. 1) comprise a plurality of 'user activatable keys 40a, 40b, 40c, 40d, 40e, 40f, and 40g. The alert device 38 is a visual indicator, such as a light emitting diode (LED). An audible annunciator could also be mounted just inside the housing of the receiver 30 to operate in conjunction with the LED
38 for alerting the user.
On the display 42 of FIG. 2, a typical database screen showing date information, time information, and financial stock information is shown. Referring to FIG. 3, upon activation of the function key 40b, the bottom line of the four line display 42 is overwritten with a function menu 70 showing a plurality of icons, each of the plurality of icons identifying a particular function. The left/right cursor keys 40e, 40f allow the user to scroll among the W~93/23930 PCT/US93/03900 ~1~~$~a various funct~.ons of the function menu 70 and to select one of the icons. Upon selection of the proper icon, e.g., 70a, the user depresses the function key 40b to activate that function.. In accordance with the present invention, the user selecas the man icon 70a to insert the displayed screen into the list of screens for quick view mode operation.
Referring to FIG. 4, the operation of the quick view controller 60 is shown as a quick view routine 100.
Initially, it is determined 102 whether there are any entries (scree:ns) assigned to the quick view mode. If there are no :>creens for quick view operation 102 when the quick view mode is selected 100, the quick view controller 60 (FIG. 1) passes operation back to the controller 52 for display of thE~ personal message status screen 103 and allows the user to select operations not essential to the operation of t:he present invention.
If there acre quick view entries 102, then selection of the quick view mode prompts display of a quick view status screen 104, a:> shown in FIG. 6. The quick view status screen (FIG. fi) comprises time information 200, date information 202, and a message indicating activation of quick view mode 204 which may be personalized by the service provider. Additionally, selected screen icons 206a, 206b and 206c indicate that three screens have been preselected by the user for display during quick view operation. F7Lag-shaped screen icon 206d indicates that a fourth screen has automatically been inserted for quick view display in accordance with the present invention.
The high7Lighting of icon 206a indicates that the left most icon 206a is the current active icon. In accordance with the present invention, activation of the read key 40a or the down cursor key 40d as a user input 106 (FIG. 4) will cause display of the selected quick view database screen, which initially is the screen indicated by the current icon :?06a (FIG. 6). To adjust the current active WO 93/23930 PCT/US93/03900: -.~
=zn.~z~os 10 icon 109, the user activates the left cursor key 40e or the right cursor key 40f for movement left or right, respectively, among the screen indication icons 206a, 206b, 206c, and 206d.
When the first selected quick view database screen is displayed 108, a timer is set 110 in controller 60 (FIG. 1) and signals using the clock 58, the time that the display driver 56 causes the selected screen to be displayed is predetermined. The predetermined time is preferably user selectable. In manual quick view operation, when the timer times out 112, the display reverts 104 to the quick view status display (FIG. 6) and awaits user selection 106 of a next quick view database screen. In automatic quick view operation, when the timer times out 112, the quick view controller 60 (FIG. 1) automatically selects the next quick view database screen 114 by retrieving the screen from the database portion 48 of the memory 44 and providing it to the display driver 56 (FIG. 1). The display driver 56 causes the selected quick view screen to be displayed 108.
In either manual or automatic operation, if timeout has not occurred 112, the user can override timer control by a key press 116 on any of the user input controls 40 (FIG. 6). For example, the user may not wish to view one of the quick view screens for the predetermined amount of time set by the timer 110. Therefore, an appropriate key press 116 such as activation of a key indicating selection of the next screen 118 would cause operation to proceed to retrieval of the next screen 114 earlier than timeout 112 of the predetermined time set in the timer 110. Any other key pressed would take operation out of the quick view database screen mode and return operation to display of the quick view status screen 104.
From the status screen 104, a user input 106 can request a quick view function menu 120 (FIG. 5). A menu request 120 is performed by activation of the function key 40b (FIG. 6) which causes display of a function menu. A
r-.
11_2112808 quick view status screen function menu 208 is shown in FIG.
7. The function menu 208 comprises a plurality of icons which can be utilized to select various quick view functions. RE:ferring back to FIG. 5, when the function menu is displayed 122 the quick view controller 60 (FIG. 1) looks for input from the left and right cursor keys 40e and 40f. The cursor keys can be used to navigate 126 the menu of functions~:?08 (FIG. 7) to allow the user to select a function. For example, if the user selects the delete function 125 as indicated by the lightning icon 208a (FIG.
7) the quick view entry (screen) indicated by the highlighted indicator icon 206a is removed from the list of quick view screens 128 and operation proceeds back to the start of the quick view routine 100. If another function is selected 125, the action indicated by the menu icon selected is performed 130 and operation returns to the start of the quick view mode 100.
Thus, it can be seen that a selective call receiver operated in accordance with the present invention allows the user to view preselected quick view screens in order to keep apprised of various information services. A preferred embodiment of the present invention allows selection of twenty (20) screens for quick view operation. When a user is not actively interacting with the multi function selective call receiver 30, the user can place the receiver into automatic quick view mode operation and the quick view controller 60 will cause the display of various preselected screens of interest to the user. These screens will be presented sequentially in a wrap-around manner such that each of the screens will be displayed until the user makes an appropriate key press 116 (FIG. 4) to exit from quick view operation.
Removal of screens from the quick view operation has been described 126, 128 (FIG. 5). Referring to FIG. 8, a flowchart of the operation of the manual insertion process whereby a database screen is user selected for quick view B

operation is chown. Initially, operation of the selective call receiver 30 (FIG. 2) is in the database operation mode wherein a database status display is active 300. The database status display is similar to the quick view status .
display shown in FIG. 6 wherein the indicator icons 206 indicate the number of databases active and a message personalized lby the service provider indicates that operation is in the database mode.
User input= 302 will allow for subsequent action. For example, the 'user may press a function key 40b (FIG. 7) and a menu of functions similar to that shown as menu 208~in FIG. ~7 will b~e presented 304. Activation of the up cursor key 40c or the side key 40g will cause the controller ~52 (FIG. 1) to pass control of the operation of the receiver 30 to the controller 60 for quick view operation 100.
Activation of the left or right movement keys 40e, 40f, respectively, allows the user to move the cursor left or right through the database indicators 206 to select a database for quick viewing.
Activation of the down cursor key 40d or the exit key 40a from the database status display 300 will allow the user to navigate 306 to a desired database screen. The current screen is displayed 308 for user perusal until when the desired screen is displayed 308. Thereupon, the function key 40b (FIG. 7) may be activated 310 to cause display of a database function menu as shown in FIG. 3. Or if the user has selected an undesired database screen, and it is displayed 308, the user may activate 310 the side key 40g to return operation to display the database status screen 300. Activation 310 of any other key other than the side or function key 40g or 40b, respectively, returns to database operation to navigate to a different database screen 306.
While the database function menu is displayed 312, the user may select any of the icons displayed by manipulation of the left and right cursor keys 40e, 40f and, when the V~%'W3/23930 PCT/US93/03900 211.2808 appropriate icon is highlighted, activating the function key 40b. If the quick view icon 70a (FIG. 3) is selected 314, a quick view entry of the currently displayed data-base screen is. created 316 and operation returns to display the current database screen without the function menu 308.
If the quick view icon 70a (FIG. 3) is not selected 314, processing determines whether the flag icon 70b (FIG. 3) is selected 318.
If the flag icon 70b is selected, the currently displayed database screen is flagged for auto quick view entry (i.e., auto entry into the list of quick view screens, when updated) in accordance with the present invention as described hereinafter. Other menu functions may be performed 318 through appropriate selection of the other function icons. 70 (FIG. 3). After performing the menu functions 318, operation returns to display the current database screen 308.
Referring to FIG. 9, flagging of the desired database for auto quick: view entry changes the display such that a flag icon 325 is alternately displayed with the character in the upper right corner of the display 42 to indicate a flagged condition. Manual insertion of a database screen into quick view has been described with reference to FIG.
8. In accordance with the preferred embodiment of the present invention, automatic insertion of a database screen into quick vie:w can be accomplished by a user flagging a particular database screen as described herein above or by a user triggering a numeric field of a database as described herein below. When an update is made via a received database message to a flagged screen or a triggered screen wherein the update causes the triggered field to be outside selected boundaries, the screen is automatically inserted as a screen for quick view operation.
Referring to FIGS. 10, 11, and 12, a flow chart of the screen trigger set operation of a selective call receiver WO 93/23930 PCT/US93/03900 ,--~~
30 of the preferred embodiment of the present invention begins when a user navigates through a database to a desired screen of information 350. The current screen is displayed 352 and processing awaits user input via one of the user controls 40a, 40b, 40c, 40d, 40e, 40f, or 40g (FIG. 2). Activation of the side key 40g as a user input 354 returns processing to the database status display screen as previously described 356. Activation of the function key 40b displays 358 the database function menu 70 (FIG. 3) on the fourth line of the display 42. Activation of any other key for the user input 354 allows the user to navigate through the database 350.
A user input 360, while the database function menu 70 is displayed, allows the user to select one of the functions offered by the function menu 70. Activation of the left and right cursor movement keys 40e and 40f, respectively, allows the user selectability of a function.
As the cursor moves from one function icon to another function icon, the function icon is back highlighted to allow ease of choice. Activation of the exit key 40a or the side key 40g takes the user out of the function mode and displays the four lines of the current database screen 352.
If the user input 360 is activation of the function key 40b, the user selects the highlighted icon. If the icon selected 362 is not the data check icon 70c or is not 363 the flag icon 70d, another function icon has been selected and processing performs other menu functions 364 before returning to display the current database screen 352. If the flag icon 70d is selected 363, the current database is flagged 365 before returning to display the flagged screen as shown in FIG. 9.
If the data check icon 70c is selected 362, a value for the current line is initially set to the top line of the display 366. Referring to FIG. 13, the user selects a current line 400 (as shown boxed) for triggering Wi"93/23930 PCT/US93/03900 11.2 8~8 information. The chosen line, or the current line, contains a desired field for user selection. Referring back to FIG. 11, the current database screen is displayed and the current line is highlighted 368. In FIG. 13, for 5 example, line 400, the second line of the display, is the current line and is therefore highlighted. A user input 370 of one of the cursor movement keys 40c, 40d allows the user to adjust the current line 372, and the database screen is again displayed with the adjusted current line 10 highlighted 368. Activation of the exit key or side key 40a, 40g takes the user out of the trigger set routine, returning to display the current database screen without a highlighted current line 352.
After choosing the appropriate line for triggering,. the 15 user activates 370 the function key 40b which initially selects the first numeric field on the line as the active field 374. The current line only is displayed with the active field highlighted 376. Activation of the cursor keys 40d, 40e as a user input 378 allows the.user to adjust, or select, the active field desired 380. As the active field is adjusted 380, the current line is displayed with the selected active field highlighted 376.
Activation, at this time, of the exit key 40a or the side key 40g as a user input 378, takes the user out of the trigger set operation and returns to display the current screen 352.
In accordance with the present invention, after the user selects the desired field 380 and that field is highlighted on the display 376, the user activates 378 the function key 40b which displays the current line while adding surrounding window values 382 and sets the active character initially to the first character of the upper window value 384. Referring to FIG. 14, the display 42 presents the current line of information "DJIA 3306.18"
410. The current line is surrounded with an upper window value 412 and a lower window value 414. The first WO 93/23930 ~z 1 ~. ~ D $ PGT/US93/03900 ,-~-,, character 416 of the upper window value 412 is the initial active character and is highlighted 386 (FIG. 12).
If a user input is received 388 involving activation of one of the cursor movement keys 40b, 40d, 40e, or 40f, an adjustment of the active character position or value is performed 390. If the cursor key activation involves activation of the left or right 40e, 40f keys, the active character position is adjusted 392 in the appropriate direction. If the up or down cursor keys 30c, 40d are activated 390, the value of the active character is adjusted 394 up or down in the appropriate direction.
After adjustment of the active character position 392 or the active character value 394, processing returns to display the current line With the surrounding window values .
384 highlighting the active character 386 as adjusted.
When the user has completed adjustment of all the active character values 394, as shown in FIG. 15, activation of the function key 40b as a user input 388 sets an active data check for the current database screen 396. Processing returns to display the database screen 352 with a "check mark" icon 425 (FIG. 16) alternately displayed in the upper right corner of the display 42 with the original character located thereat.
Activation of the data check trigger values allows a user to bracket normal activity or predictable activity of a varying value such as a stock market quotation or a baseball score. When an update is received for an active data check screen which causes the active numeric field value to become greater than the upper window value or less than the lower window value, the user is alerted and the screen is automatically inserted into the quick view operation. Thus, when movement of a stock reaches a range of interest to the user, the user will be notified by alert generation and will be able to view the stock quotation in the quick view mode without tedious manipulation of user controls to select the appropriate screen. An alternate x"'~93/23930 PCT/US93/03900 ~ii28~8 embodiment of the present invention could allow triggering of data field:> comprising non-numeric data, such as alphanumeric data. If an update is not equivalent to the triggers stored, then the user will be alerted.
The automatic quick view entry operation of the controller 52 (FIG. 1) in accordance with the preferred embodiment of the present invention is shown in FIGS. 17 and 18. After- processing starts 450, the controller 52 awaits reception of a database update message 452. When the database block is received 452, the block is examined to see if the block identification is appropriate 454. The user may subscribe to various databases and, when the database blocl~;s arrive, they are associated with an address identifying the database in a manner known to those skilled in the art. If the address is not an active address for the selective call receiver 454 (i.e., a block identification is not correct) the data- base block is rejected 456 and processing returns to await reception of a next database block 452.
If the database block identification is acceptable 454, the controller 52 examines the database portion 48 of the RAM 44 (FIG. J.) to determine 456 whether a database corresponding to the database block received exists in the memory 46. Ii: the database block does not exist 956 in RAM
44, a database block is created 458 in accordance with the received database block. If the database block does exist in memory 456, the location of the currently stored database blocl~; in the RAM 44 is found 460 and the new data received is placed into the RAM 44 at the location specified 462 by the database block information received.
In accordance with the present invention, the screen in which the new data is entered 462 is examined to determine if the screen has been flagged 464 by the user. If the screen is flagged 464 when an update is received, the quick view screens are examined 466 to determine if an entry for the flagged screen already exists in quick view. If the WO 93/23930 PCT/US93/03900 --,~
211 ~~,,.g~p 8 flagged screen is already inserted into quick view 466, the old entry of the quick view screen is updated 468, the icon on the quick view standby screen 206 (FIG. 6) is set for "unread" operation 470, and an alert is generated 472. The alert notifies the user that an update has occurred to a quick view screen and can be a different alert than the conventional alert reception of personal messages. After the alert is generated 472, processing by the controller 52 (FIG. 1) of received information returns to await reception of a next database block 452.
If a screen has been flagged 464, but a quick view entry does not exist for the screen 466, the number of screens in quick view are examined 474 to determine if space is available for addition of a new quick view screen.
If no space is available 474, the flagged screen is rejected entry into quick view 476 but the user is nevertheless alerted 472 to notify that an update of a flagged screen has occurred.
If space is available in quick view for addition of another screen 474, the flag icon 206d (FIG. 6) is displayed on the quick view status screen to indicate that an auto entry insertion of a screen has occurred 478 in accordance with the present invention. The updated screen is added as a new entry to quick view 480 and the user alert is generated 472. Processing then returns to await reception of the next database block 452. The updated screen is added as a new entry to quick view 480 and the user alert is generated 472. Processing then returns to await reception of the next database block 452.
In accordance with a further feature of the present invention, if the screen being updated is not flagged 464 but a data check trigger is activated for the screen 482, the updated value of the selected data field is compared to the stored data check limits 489 to determine 486 whether the updated values are within or outside the range set by the data check limit. If the updated value is within the ""'93/23930 PCT/US93/03900 range of the atored limit 486, the increase or decrease in ' the value is o f no interest to the user so the alert is not generated and the screen is not stored into quick view.
Instead, processing returns to await reception of the next database blocJc received 452.
If, on the other hand, the updated values are outside the data checlt ranges 486, processing proceeds to insert the screen into quick view in the same manner as a flagged screen update is inserted therein. If the triggered screen is already in quick view 466, the old entry is updated 468, the icon for "unread" operation is set 470, and an alert is generated 472 before processing returns to step 452 to await reception of the next database block. If the triggered screen is not in quick view 466 and space is available 474, the flagged icon is used to indicate auto entry of a screen into quick view 478 and a new quick view entry is created 480 for the updated screen. The user alert is generated 472 and processing returns to await the next database block received. Finally, if the data check limits are exceeded by the updated values 486, and no quick . view screen exists for the updated triggered screen 466, and if there is no space available 474 in quick view for an additional screen, entry of the triggered screen into quick view is rejected 476. The user, however, is notified by generation of an alert 472 before processing returns to await the next database block received 452.
By now it should be appreciated there has been provided a method and apparatus for notifying the user of selected updates of information and allowing the user a quick access to the screen or screens of updated information. In one contemplated mode of operation, the user can select various triggers and flags, place the selective call receiver into a charger on his desk, and place the selective call receiver into quick view operation mode. When any information of interest to the user is received, the user is alerted and can view the information automatically as it WO 93/23930 PCT/U593/03900 --~.
~l~.z~~$
is displayed in the quick view screens. Stock quotations are particularly suited to the trigger feature of the present invention. Additionally, news stories of interest to a user are particularly suited for flagging in 5 accordance with the present invention. Thus, when a stock quotation value falls outside the preselected limits set by the user or when a news story is updated with more information, the user will be notified and can quickly and easily view the updated information.
What is claimed is:
UPDATED INfFORMATION IN A SELECTIVE CALL RECEIVER
20 Field of the Invention This invention relates in general to selective call receivers, and in particular to selective call receivers for receiving information services.
Background of the Invention Selective call receivers are radio frequency receivers which selectively receive messages. Conventionally, a selective call receiver examines a selective call signal to determine whether the receiver has been addressed. When an address assigned to the receiver is detected, the selective call receiver decodes a selective call message. The user is alerted that a message has been received and the message can thereafter be presented, either as a voice message or a numeric or alphanumeric displayed message. The message may be displayed on a conventional display such as a liquid B
' WO 93/23930 PCT/US93/03900 .-~", 1.1.28D8 2 crystal display (LCD). It is desirable that selective call receivers be portable and, consequently, most selective call receivers have LCD's of limited size. Additionally, most selectivE; call receivers have limited room for user input controls.
More recently, users of selective call receivers desire additional features, such as reception of information services, whi:Le maintaining the desire for small portable receivers. Information services are services which provide regularly updated messages, such as news services (UPI), financial services (Dow Jones Stock Reports), or sports services. One such information services selective call system is described in United States Patent No. 4,895,491.
A user can subscribe to several information services and receive information on many topics. Each topic may consist of several screens (i.e. information capable of being displayed on the LCD at one time). To view a screen of information, the user manipulates the limited number of user input controls to reach the screen. This manipulation could consist of numerous activations of user controls.
The information is updated regularly by selective call messages comprising update information. If the user is alerted each time one of the screens is updated, it is likely that the user would be continuously alerted.
Conversely, if the user is not alerted when a screen is updated, the user would be unaware of changes in information which are of importance to the user. Further, if the user elects to be alerted of an update and misses the alert either by having the alert turned off or not having the receiver on or near the user's person when the alert is activated, the user has no way of knowing that an update of information has occurred.
Additionally, access to updated information poses the ' same difficulties as access to any screen of information.
It is undesirable for the user to be forced to continuously Vlc~""n3/23930 PCT/US93/03900 manipulate the user controls to select screens of interest in order to view their updated information.
Thus, what is needed is a method and apparatus for notifying the user of selected updates of information and for allowing a user quick access to the screen or screens of updated information.
Summary of the Invention In carrying out the objects of the invention in one form there is provided a selective call receiver comprising a receiver means for receiving update information, a display means for displaying a screen of information, and a user selectable means for programming trigger boundaries associated with a portion of the screen of information.
The selective call receiver also comprises an alert means for providing an alert in response to the update information received comprising information outside the trigger boundaries, and a quick view means for adding the screen of information comprising the update information to a list of screens if the update information comprises information outside the trigger boundaries. The user selectable means further permits direct user access to a screen of information if the screen of information is on the list of screens.
In another form, the present invention provides a selective call. receiver for receiving selective call messages. The: selective call receiver comprises a receiving means for receiving selective call messages comprising update messages, a memory means for storing a plurality of screens, a user input means for receiving input signals from a plurality of user keys in response to user activation of the user keys, and a display means for displaying the: plurality of screens to a user. A first control means is coupled to the memory means and the display means for maintaining a list of screens comprising 2 ~ ~ ~ 4 PC'f/US93/03900:--~
user selected ones of the plurality of screens and for permitting the user to display one of the plurality of screens with a minimal number of user activations of the user keys if the one of the plurality of screens is on the list of screens. A second control means for maintaining the plurality of screens comprises a flagging means coupled to the user input means for flagging one of the plurality of screens in response to user activation of the user keys, an updating means for updating the plurality of screens in response to the update messages, a first determining means for determining whether an update message updates a flagged one of the plurality of screens, and a signalling means coupled to the first control means for signalling the first control means to add an updated one of the plurality of screens to the list of screens if the first determining means determines that the updated one of the plurality of screens is a flagged one of the plurality of screens.

FIGS. 17 a.nd 18 is a flow chart of a quick view auto insert mode of operation of the information services receiver of FI:G. 2 upon receipt of database selective call messages in accordance with the preferred embodiment of the present invention.
Detailed Description of the Invention Referring to FIG. 1, a selective call system in accordance with a preferred embodiment of the present invention transmits two types of signals: information services signals and personal message signals. As is well WO 93/23930 ~ ~ ~ ~~ ~ ~ ~ 6 PCT/US93/03900,.-..
known to those skilled in the art, an originator of a personal selective call message inputs message information via a telephone input 10 to a paging terminal 12. The paging terminal 12 comprises an encoder 14 for encoding the message information into selective call signals and a transmitter 16 for transmitting the selective call signals via an antenna 18.
Information services signals are derived from information services 20 which compile financial, sports, news, etc. information and forward the information to a data center 22. The data center 22 compiles the information provided by the information services 20 into appropriate messages which are provided to a paging terminal 12' for transmission as selective call signals therefrom. The paging terminal 12' similarly comprises an encoder 14' a transmitter 16' and an antenna 18'.
Thus, it can be seen that a selective call system in accordance with the preferred embodiment of the present invention broadcasts signals comprising personal message selective call messages and information services selective call messages for reception by a receiver 30. The receiver receives the selective call signals at an antenna 32 which generates electrical signals in response to the radio frequency signals received and forwards the signals to 25 receiver circuitry 34 for demodulation. The demodulated signal is provided to a microprocessor 36 for processing thereby. The microprocessor 36 is coupled to an alert device 38, user input controls 40, and a display 42 for interfacing with a user of the selective call receiver 30.
30 Additionally, the microprocessor 36 is coupled to an external random excess memory (RAM) 44 for storing information therein and for retrieving information therefrom. In accordance with the preferred embodiment of the present invention, the external RAM 44 has designated portions for storing personal messages 46 and for storing databases 48. The databases are stored in a portion of the r 2112808 ~ .
external RAM 48 in a manner which allows a user to access the information services data stored therein.
When a selective call signal is received and demodulated b:y the receiver circuitry 34, address detection block 50 of tl'ze microprocessor 36 examines the selective call signal to determine if an address assigned to the microprocessor is present within the signal. When an address assigned to the selective call receiver 30 is detected by the address detection block 50, a controller 52 is signaled to start a decoder block 54 decoding the received and demodulated selective call signal. The decoded signal is provided from the decoder block 54 to the controller 52 for processing thereby. The controller 52 stores the de<:oded selective call message in portions 46, 48 of the external RAM 44. The controller 52 thereafter provides a signal to the alert device 38 to alert the user that a select~_ve call message has been received. Upon manipulation of the user input control 40 by the user, the controller wi7_1 provide the decoded selective call message to a display driver 56 for generation of a user readable display upon t:he display 42. A clock 58 is coupled to the controller 52 to provide conventional clocking functions allowing for proper operation of the controller 52 and the microprocessor 36.
The selective call receiver 30 is user operable in three modes in accordance with the preferred embodiment of the present irwention: a personal message mode, a database mode, and a qu~.ick view mode. When operating in the personal message mode, the selective call receiver can function as a conventional pager whereby the user can manipulate the: user input controls 40 to select and read various personal messages stored in the personal message portion 46 of the RAM 44. During database mode operation, the user can manipulate the user input controls 40 to select and read various screens of the databases stored in the database portion 48 of the RAM 44.
s WO 93/23930 PCT/US93/03900,.,,, ~1,~.2808 8 In accordance with the preferred embodiment of the present invention, quick view mode operation is a mode of operation for allowing a user quick access to selected screens under the control of a quick view controller 60.
The quick view controller 60 is coupled to the controller 52 for controlling the operation of the microprocessor 36 when the user places the selective call receiver 30 into the quick view operation mode. The quick view operation mode involves an automatic quick view mode wherein the quick view controller 60 automatically retrieves user selected screens from the database 48 and provides those screens sequentially to the display driver 56 for display upon the disp:Lay 42 or a manual quick view mode wherein selected screens may be user selectably retrieved from the memory 48 for display without the user having to navigate through a database to the screen. The clock 58 is coupled to the quick 'view controller 60 for controlling the amount of time that ~sach of the user selective screens are displayed upon the display 42.
Referring next to FIG. 2, a preferred embodiment of the multi-function selective call receiver 30 of FIG. 1 is depicted. The user input controls 40 (FIG. 1) comprise a plurality of 'user activatable keys 40a, 40b, 40c, 40d, 40e, 40f, and 40g. The alert device 38 is a visual indicator, such as a light emitting diode (LED). An audible annunciator could also be mounted just inside the housing of the receiver 30 to operate in conjunction with the LED
38 for alerting the user.
On the display 42 of FIG. 2, a typical database screen showing date information, time information, and financial stock information is shown. Referring to FIG. 3, upon activation of the function key 40b, the bottom line of the four line display 42 is overwritten with a function menu 70 showing a plurality of icons, each of the plurality of icons identifying a particular function. The left/right cursor keys 40e, 40f allow the user to scroll among the W~93/23930 PCT/US93/03900 ~1~~$~a various funct~.ons of the function menu 70 and to select one of the icons. Upon selection of the proper icon, e.g., 70a, the user depresses the function key 40b to activate that function.. In accordance with the present invention, the user selecas the man icon 70a to insert the displayed screen into the list of screens for quick view mode operation.
Referring to FIG. 4, the operation of the quick view controller 60 is shown as a quick view routine 100.
Initially, it is determined 102 whether there are any entries (scree:ns) assigned to the quick view mode. If there are no :>creens for quick view operation 102 when the quick view mode is selected 100, the quick view controller 60 (FIG. 1) passes operation back to the controller 52 for display of thE~ personal message status screen 103 and allows the user to select operations not essential to the operation of t:he present invention.
If there acre quick view entries 102, then selection of the quick view mode prompts display of a quick view status screen 104, a:> shown in FIG. 6. The quick view status screen (FIG. fi) comprises time information 200, date information 202, and a message indicating activation of quick view mode 204 which may be personalized by the service provider. Additionally, selected screen icons 206a, 206b and 206c indicate that three screens have been preselected by the user for display during quick view operation. F7Lag-shaped screen icon 206d indicates that a fourth screen has automatically been inserted for quick view display in accordance with the present invention.
The high7Lighting of icon 206a indicates that the left most icon 206a is the current active icon. In accordance with the present invention, activation of the read key 40a or the down cursor key 40d as a user input 106 (FIG. 4) will cause display of the selected quick view database screen, which initially is the screen indicated by the current icon :?06a (FIG. 6). To adjust the current active WO 93/23930 PCT/US93/03900: -.~
=zn.~z~os 10 icon 109, the user activates the left cursor key 40e or the right cursor key 40f for movement left or right, respectively, among the screen indication icons 206a, 206b, 206c, and 206d.
When the first selected quick view database screen is displayed 108, a timer is set 110 in controller 60 (FIG. 1) and signals using the clock 58, the time that the display driver 56 causes the selected screen to be displayed is predetermined. The predetermined time is preferably user selectable. In manual quick view operation, when the timer times out 112, the display reverts 104 to the quick view status display (FIG. 6) and awaits user selection 106 of a next quick view database screen. In automatic quick view operation, when the timer times out 112, the quick view controller 60 (FIG. 1) automatically selects the next quick view database screen 114 by retrieving the screen from the database portion 48 of the memory 44 and providing it to the display driver 56 (FIG. 1). The display driver 56 causes the selected quick view screen to be displayed 108.
In either manual or automatic operation, if timeout has not occurred 112, the user can override timer control by a key press 116 on any of the user input controls 40 (FIG. 6). For example, the user may not wish to view one of the quick view screens for the predetermined amount of time set by the timer 110. Therefore, an appropriate key press 116 such as activation of a key indicating selection of the next screen 118 would cause operation to proceed to retrieval of the next screen 114 earlier than timeout 112 of the predetermined time set in the timer 110. Any other key pressed would take operation out of the quick view database screen mode and return operation to display of the quick view status screen 104.
From the status screen 104, a user input 106 can request a quick view function menu 120 (FIG. 5). A menu request 120 is performed by activation of the function key 40b (FIG. 6) which causes display of a function menu. A
r-.
11_2112808 quick view status screen function menu 208 is shown in FIG.
7. The function menu 208 comprises a plurality of icons which can be utilized to select various quick view functions. RE:ferring back to FIG. 5, when the function menu is displayed 122 the quick view controller 60 (FIG. 1) looks for input from the left and right cursor keys 40e and 40f. The cursor keys can be used to navigate 126 the menu of functions~:?08 (FIG. 7) to allow the user to select a function. For example, if the user selects the delete function 125 as indicated by the lightning icon 208a (FIG.
7) the quick view entry (screen) indicated by the highlighted indicator icon 206a is removed from the list of quick view screens 128 and operation proceeds back to the start of the quick view routine 100. If another function is selected 125, the action indicated by the menu icon selected is performed 130 and operation returns to the start of the quick view mode 100.
Thus, it can be seen that a selective call receiver operated in accordance with the present invention allows the user to view preselected quick view screens in order to keep apprised of various information services. A preferred embodiment of the present invention allows selection of twenty (20) screens for quick view operation. When a user is not actively interacting with the multi function selective call receiver 30, the user can place the receiver into automatic quick view mode operation and the quick view controller 60 will cause the display of various preselected screens of interest to the user. These screens will be presented sequentially in a wrap-around manner such that each of the screens will be displayed until the user makes an appropriate key press 116 (FIG. 4) to exit from quick view operation.
Removal of screens from the quick view operation has been described 126, 128 (FIG. 5). Referring to FIG. 8, a flowchart of the operation of the manual insertion process whereby a database screen is user selected for quick view B

operation is chown. Initially, operation of the selective call receiver 30 (FIG. 2) is in the database operation mode wherein a database status display is active 300. The database status display is similar to the quick view status .
display shown in FIG. 6 wherein the indicator icons 206 indicate the number of databases active and a message personalized lby the service provider indicates that operation is in the database mode.
User input= 302 will allow for subsequent action. For example, the 'user may press a function key 40b (FIG. 7) and a menu of functions similar to that shown as menu 208~in FIG. ~7 will b~e presented 304. Activation of the up cursor key 40c or the side key 40g will cause the controller ~52 (FIG. 1) to pass control of the operation of the receiver 30 to the controller 60 for quick view operation 100.
Activation of the left or right movement keys 40e, 40f, respectively, allows the user to move the cursor left or right through the database indicators 206 to select a database for quick viewing.
Activation of the down cursor key 40d or the exit key 40a from the database status display 300 will allow the user to navigate 306 to a desired database screen. The current screen is displayed 308 for user perusal until when the desired screen is displayed 308. Thereupon, the function key 40b (FIG. 7) may be activated 310 to cause display of a database function menu as shown in FIG. 3. Or if the user has selected an undesired database screen, and it is displayed 308, the user may activate 310 the side key 40g to return operation to display the database status screen 300. Activation 310 of any other key other than the side or function key 40g or 40b, respectively, returns to database operation to navigate to a different database screen 306.
While the database function menu is displayed 312, the user may select any of the icons displayed by manipulation of the left and right cursor keys 40e, 40f and, when the V~%'W3/23930 PCT/US93/03900 211.2808 appropriate icon is highlighted, activating the function key 40b. If the quick view icon 70a (FIG. 3) is selected 314, a quick view entry of the currently displayed data-base screen is. created 316 and operation returns to display the current database screen without the function menu 308.
If the quick view icon 70a (FIG. 3) is not selected 314, processing determines whether the flag icon 70b (FIG. 3) is selected 318.
If the flag icon 70b is selected, the currently displayed database screen is flagged for auto quick view entry (i.e., auto entry into the list of quick view screens, when updated) in accordance with the present invention as described hereinafter. Other menu functions may be performed 318 through appropriate selection of the other function icons. 70 (FIG. 3). After performing the menu functions 318, operation returns to display the current database screen 308.
Referring to FIG. 9, flagging of the desired database for auto quick: view entry changes the display such that a flag icon 325 is alternately displayed with the character in the upper right corner of the display 42 to indicate a flagged condition. Manual insertion of a database screen into quick view has been described with reference to FIG.
8. In accordance with the preferred embodiment of the present invention, automatic insertion of a database screen into quick vie:w can be accomplished by a user flagging a particular database screen as described herein above or by a user triggering a numeric field of a database as described herein below. When an update is made via a received database message to a flagged screen or a triggered screen wherein the update causes the triggered field to be outside selected boundaries, the screen is automatically inserted as a screen for quick view operation.
Referring to FIGS. 10, 11, and 12, a flow chart of the screen trigger set operation of a selective call receiver WO 93/23930 PCT/US93/03900 ,--~~
30 of the preferred embodiment of the present invention begins when a user navigates through a database to a desired screen of information 350. The current screen is displayed 352 and processing awaits user input via one of the user controls 40a, 40b, 40c, 40d, 40e, 40f, or 40g (FIG. 2). Activation of the side key 40g as a user input 354 returns processing to the database status display screen as previously described 356. Activation of the function key 40b displays 358 the database function menu 70 (FIG. 3) on the fourth line of the display 42. Activation of any other key for the user input 354 allows the user to navigate through the database 350.
A user input 360, while the database function menu 70 is displayed, allows the user to select one of the functions offered by the function menu 70. Activation of the left and right cursor movement keys 40e and 40f, respectively, allows the user selectability of a function.
As the cursor moves from one function icon to another function icon, the function icon is back highlighted to allow ease of choice. Activation of the exit key 40a or the side key 40g takes the user out of the function mode and displays the four lines of the current database screen 352.
If the user input 360 is activation of the function key 40b, the user selects the highlighted icon. If the icon selected 362 is not the data check icon 70c or is not 363 the flag icon 70d, another function icon has been selected and processing performs other menu functions 364 before returning to display the current database screen 352. If the flag icon 70d is selected 363, the current database is flagged 365 before returning to display the flagged screen as shown in FIG. 9.
If the data check icon 70c is selected 362, a value for the current line is initially set to the top line of the display 366. Referring to FIG. 13, the user selects a current line 400 (as shown boxed) for triggering Wi"93/23930 PCT/US93/03900 11.2 8~8 information. The chosen line, or the current line, contains a desired field for user selection. Referring back to FIG. 11, the current database screen is displayed and the current line is highlighted 368. In FIG. 13, for 5 example, line 400, the second line of the display, is the current line and is therefore highlighted. A user input 370 of one of the cursor movement keys 40c, 40d allows the user to adjust the current line 372, and the database screen is again displayed with the adjusted current line 10 highlighted 368. Activation of the exit key or side key 40a, 40g takes the user out of the trigger set routine, returning to display the current database screen without a highlighted current line 352.
After choosing the appropriate line for triggering,. the 15 user activates 370 the function key 40b which initially selects the first numeric field on the line as the active field 374. The current line only is displayed with the active field highlighted 376. Activation of the cursor keys 40d, 40e as a user input 378 allows the.user to adjust, or select, the active field desired 380. As the active field is adjusted 380, the current line is displayed with the selected active field highlighted 376.
Activation, at this time, of the exit key 40a or the side key 40g as a user input 378, takes the user out of the trigger set operation and returns to display the current screen 352.
In accordance with the present invention, after the user selects the desired field 380 and that field is highlighted on the display 376, the user activates 378 the function key 40b which displays the current line while adding surrounding window values 382 and sets the active character initially to the first character of the upper window value 384. Referring to FIG. 14, the display 42 presents the current line of information "DJIA 3306.18"
410. The current line is surrounded with an upper window value 412 and a lower window value 414. The first WO 93/23930 ~z 1 ~. ~ D $ PGT/US93/03900 ,-~-,, character 416 of the upper window value 412 is the initial active character and is highlighted 386 (FIG. 12).
If a user input is received 388 involving activation of one of the cursor movement keys 40b, 40d, 40e, or 40f, an adjustment of the active character position or value is performed 390. If the cursor key activation involves activation of the left or right 40e, 40f keys, the active character position is adjusted 392 in the appropriate direction. If the up or down cursor keys 30c, 40d are activated 390, the value of the active character is adjusted 394 up or down in the appropriate direction.
After adjustment of the active character position 392 or the active character value 394, processing returns to display the current line With the surrounding window values .
384 highlighting the active character 386 as adjusted.
When the user has completed adjustment of all the active character values 394, as shown in FIG. 15, activation of the function key 40b as a user input 388 sets an active data check for the current database screen 396. Processing returns to display the database screen 352 with a "check mark" icon 425 (FIG. 16) alternately displayed in the upper right corner of the display 42 with the original character located thereat.
Activation of the data check trigger values allows a user to bracket normal activity or predictable activity of a varying value such as a stock market quotation or a baseball score. When an update is received for an active data check screen which causes the active numeric field value to become greater than the upper window value or less than the lower window value, the user is alerted and the screen is automatically inserted into the quick view operation. Thus, when movement of a stock reaches a range of interest to the user, the user will be notified by alert generation and will be able to view the stock quotation in the quick view mode without tedious manipulation of user controls to select the appropriate screen. An alternate x"'~93/23930 PCT/US93/03900 ~ii28~8 embodiment of the present invention could allow triggering of data field:> comprising non-numeric data, such as alphanumeric data. If an update is not equivalent to the triggers stored, then the user will be alerted.
The automatic quick view entry operation of the controller 52 (FIG. 1) in accordance with the preferred embodiment of the present invention is shown in FIGS. 17 and 18. After- processing starts 450, the controller 52 awaits reception of a database update message 452. When the database block is received 452, the block is examined to see if the block identification is appropriate 454. The user may subscribe to various databases and, when the database blocl~;s arrive, they are associated with an address identifying the database in a manner known to those skilled in the art. If the address is not an active address for the selective call receiver 454 (i.e., a block identification is not correct) the data- base block is rejected 456 and processing returns to await reception of a next database block 452.
If the database block identification is acceptable 454, the controller 52 examines the database portion 48 of the RAM 44 (FIG. J.) to determine 456 whether a database corresponding to the database block received exists in the memory 46. Ii: the database block does not exist 956 in RAM
44, a database block is created 458 in accordance with the received database block. If the database block does exist in memory 456, the location of the currently stored database blocl~; in the RAM 44 is found 460 and the new data received is placed into the RAM 44 at the location specified 462 by the database block information received.
In accordance with the present invention, the screen in which the new data is entered 462 is examined to determine if the screen has been flagged 464 by the user. If the screen is flagged 464 when an update is received, the quick view screens are examined 466 to determine if an entry for the flagged screen already exists in quick view. If the WO 93/23930 PCT/US93/03900 --,~
211 ~~,,.g~p 8 flagged screen is already inserted into quick view 466, the old entry of the quick view screen is updated 468, the icon on the quick view standby screen 206 (FIG. 6) is set for "unread" operation 470, and an alert is generated 472. The alert notifies the user that an update has occurred to a quick view screen and can be a different alert than the conventional alert reception of personal messages. After the alert is generated 472, processing by the controller 52 (FIG. 1) of received information returns to await reception of a next database block 452.
If a screen has been flagged 464, but a quick view entry does not exist for the screen 466, the number of screens in quick view are examined 474 to determine if space is available for addition of a new quick view screen.
If no space is available 474, the flagged screen is rejected entry into quick view 476 but the user is nevertheless alerted 472 to notify that an update of a flagged screen has occurred.
If space is available in quick view for addition of another screen 474, the flag icon 206d (FIG. 6) is displayed on the quick view status screen to indicate that an auto entry insertion of a screen has occurred 478 in accordance with the present invention. The updated screen is added as a new entry to quick view 480 and the user alert is generated 472. Processing then returns to await reception of the next database block 452. The updated screen is added as a new entry to quick view 480 and the user alert is generated 472. Processing then returns to await reception of the next database block 452.
In accordance with a further feature of the present invention, if the screen being updated is not flagged 464 but a data check trigger is activated for the screen 482, the updated value of the selected data field is compared to the stored data check limits 489 to determine 486 whether the updated values are within or outside the range set by the data check limit. If the updated value is within the ""'93/23930 PCT/US93/03900 range of the atored limit 486, the increase or decrease in ' the value is o f no interest to the user so the alert is not generated and the screen is not stored into quick view.
Instead, processing returns to await reception of the next database blocJc received 452.
If, on the other hand, the updated values are outside the data checlt ranges 486, processing proceeds to insert the screen into quick view in the same manner as a flagged screen update is inserted therein. If the triggered screen is already in quick view 466, the old entry is updated 468, the icon for "unread" operation is set 470, and an alert is generated 472 before processing returns to step 452 to await reception of the next database block. If the triggered screen is not in quick view 466 and space is available 474, the flagged icon is used to indicate auto entry of a screen into quick view 478 and a new quick view entry is created 480 for the updated screen. The user alert is generated 472 and processing returns to await the next database block received. Finally, if the data check limits are exceeded by the updated values 486, and no quick . view screen exists for the updated triggered screen 466, and if there is no space available 474 in quick view for an additional screen, entry of the triggered screen into quick view is rejected 476. The user, however, is notified by generation of an alert 472 before processing returns to await the next database block received 452.
By now it should be appreciated there has been provided a method and apparatus for notifying the user of selected updates of information and allowing the user a quick access to the screen or screens of updated information. In one contemplated mode of operation, the user can select various triggers and flags, place the selective call receiver into a charger on his desk, and place the selective call receiver into quick view operation mode. When any information of interest to the user is received, the user is alerted and can view the information automatically as it WO 93/23930 PCT/U593/03900 --~.

is displayed in the quick view screens. Stock quotations are particularly suited to the trigger feature of the present invention. Additionally, news stories of interest to a user are particularly suited for flagging in 5 accordance with the present invention. Thus, when a stock quotation value falls outside the preselected limits set by the user or when a news story is updated with more information, the user will be notified and can quickly and easily view the updated information.
