digital audio signal decoded by the voice encodingldecoding portion 3 into an analog audio signal, a speaker 14 8 for outputting the audio information as the analog audio signal, a control signal processing portion 9 for decoding control information included in the encoded digital signal from ,the radio portion 5, and for encoding telephone number information stored in a memory 12 (as described later), and outputting the telephone number information to the switch 4 as an encoded digital signal, a microcomputer 10 for recording the telephone number information included in the control information from the control signal processing portion 9 in the memory 12 according to the time when the information is received and for processing the telephone number information storea3 in the memory 12 in order to display it on the display portion 13 (as described later) by an operating portion 11, the operating portion 11 for reading the telephone number information out of the memory 12 for example and for inputting operating information such as carrying out calling as an operating signal, a memory 12 for storing the telephone number information processed by the microcomputer 10 as an incoming reacord information, a display portion 13 for displaying a message in response to the operating information and various operations, and a control timing generating circuit 14 for controlling switching timing of the switch 4. In Figure 1 a voice processing portion 100 is. shown to comprise A/D converter 2, the voice encoding/decoding portion 3, and the D/A converter 7.
Figure 2 is a functional block diagram relating especially to a recording process of the incoming telephone number conducted in the microcomputer 10 in the system configuration of the digital radio telephone shown in Figure 1. Figure 2 shows a telephone number information detecting means 40 for detecting whether the telephone number information is included in the control information from the control signal processing portion 9; a time information management means 50 for specifying a receiving time of the control information including the telephone number information according to the time from a clock portion (not shown) provided in the digital radio telephone and for outputting the time information; an extension/external line judging means 70 for identifying and judging whether the call is from the extension or from the external line, in case the telephone number information exists, by detecting extension/external line identification information included in the control information for example; an external line information addition means 80 for extracting the telephone number information from the control information and for outputting the telephone number information in the event that the call is from the extension line, while for extracting the telephone number information from the control information, adding external line calling information to the telephone number information, and outputting the telephone number information as new telephone number information in the event that the call is from the external line; and a memory management means 60 for recording the telephone number information from the external line information addition means 80 in the memory 12 (Figure 1) as incoming record information in correspondence to the time information from the time information management means 50.
Figure 3 is a functional block diagram especially relating to a detailed process conducted in the memory management means 60 shown in Figure 2 which is the functional block diagram regarding the incoming telephone number' process conducted in the microcomputer 10. In Figure 3, a telephone number information comparison means 67 compares the telephone number information from the external line information addition means 80 with the telephone number precedingly recorded in the memory and outputs whether these telephone number information are identical to each other. The operating portion 11 gives instructions to compare or not with the; telephone number information. A vacant memory judging means 61 judges whether a vacant area exists in the memory 12 to stare the telephone number information of a new incoming call according to an output of the telephone number information connparison means ("record all" without comparison or "no identical information" as a result of comparison). A rerecording means 62 deletes unnecessary information (the oldest information or a plurality of identical information entries) of the incoming record information recorded in the memory 12 according to a judging result of the vacant memory judging means 61 ("no vacancy") or the output of the telephone number information comparison means 67 ("identical information" as a result of comparison) and keeps vacant areas to newly rerecord the remaining incoming record information. A
~ 9 0 1 ~ .~:
recording means 63 records the telephone number information in a desired area in the memory 12 in correspondence to time information as an incoming record information according to "vacant" as a judging result of the vacant memory judging means 61 or "vacant " as a judging result of the rerecording means 62. Hence, the operating portion 11 causes the display portion 13 to display the telephone number information one after another in a circulative manner beginning with the telephone number information which was most-recently received.
Figure 4 is a flow chart showing an operation of the recording process of the incoming telephone number. The operation of the present embodiment shown in Figure 2 is explained using Figures 3 and 4.
First, in step 401, the telephone number information detecting means 40 detects whether the telephone number information is included in the control information from the control signal processing portion 9. If the telephone number information is not included, the process is completed. If telephone number information is included, in a next step 402 the extension/external line judging means 70 identifies and judges whether the telephone is in the extension or in the external line. If the call is from the external line, in a next step 403, the external line information addition means 80 adds external line identifying information ("0" as the external line calling number, for example) to the telephone number information in the control information. If the call is in the extension, the external line information addition means 80 extracts the telephone number information from the control information and outputs the telephone number information.
Then, in step 404, the time information management means 50 specifies the time when the telephone number information is received. In next step 405, the operating portion 11 instructs the microcomputer 10 whether to record all the same incoming numbers, or only the latest numbers, received form the same calling party, as determined by the user.
If all the identical incoming telephone numbers are to be recorded, the operation goes to step 406. If only the latest incoming telephone number out of the identical incoming telephone numbers is to be recorded, the operation goes to a step 410. In step 410, the telephone number information comparison means 67 compares the latest incoming telephone number information with the incoming telephone number information recorded previously in incoming recording memory 121 (Figure 3) which comprises a first memory portion in the memory 12. If the incoming telephone number information is not identical to the registered telephone number information, the operation goes to step 406.
940 1 ~~~:.
s On the other hand, if the incoming telephone number information is identical to the recorded telephone number information, the operation goes to step 411. In step 411, the recording means 63 deletes the incoming telephone number information recorded previously in the incoming recording memory 121 and goes to a step 408.
In step 406, the vacant memory judging means 61 judges whether the area for new incoming telephone number information in the incoming recording memory 121 can be used. If the incoming recording memory 121 is not occupied, the incoming telephone number information is recorded in the incoming recording memory 121 together with the corresponding time information. If the incoming recording memory :121 is occupied, the operation goes to a next step 407, where the telephone number information with the oldest time information is deleted from the incoming recording memory 121. In the next step 408, second oldest telephone number information is incremented and recorded into the location in the incoW ing recording memory 121 where the oldest time information is deleted. This operation is repeated continuously. In a next step 409, latest incoming telephone number information is finally recorded together with the time information into a location in the vacant incoming recording memory 121, following which the operation is completed. Figure 5 shows a memory arrangement of the incoming telephone numbers and their incoming times in the incoming recording memory 121. As shown in Figure 5, the respective incoming telephone number is stored in each address in combination with its incoming time in the incoming recording memory 121.
Figure 6 is a flow chart depicting operation of display processes associated with recordal of the incoming telephone number in the incoming recording memory 121. The operation of the display processes is explained below using Figures 3 and 6.
First, in step 601, in response to user input, the operating portion 11 instructs to display the incoming telephone number. In next step 602, a memory record judging means 66 judges whether incoming telephone number information is recorded so far into the incoming recording memory 121. If no incoming telephone number information is recorded so far, in step 603, a warning sound is given from the spealker 8 to inform that no incoming telephone number information is recorded and also a warning indication is displayed on the display portion 13, whereupon, the display process is completed. If the incoming telephone number information is recorded, an incoming re~~ord reading means 64 reads an incoming telephone number received most recently together with its incoming time out of the incoming recording memory 121, and in step 604, the display 2~~~~ ~ ~~
portion 13 displays the telephone number and the incoming time. In next step 605, the display process finishes according to an instruction of the operating portion 11. For displaying other incoming telephone numbers, in next step 606, the operating portion 11 instructs to switch the display indication of the incoming telephone number.
In response to the instruction from the operation portion 11, in step 607, the display of an immediately preceding incoming telephone number or an immE:diately succeeding incoming telephone number is switched back and forth. After that, the operation returns to the step 605. Steps 605, 606, 607 are then repeated until a desired incoming telephone number is displayed.
Figure 7 shows a displaying order of the incoming telephone numbers when five incoming telephone numbers are recorded. According to the instructions from the operating portion 11, the displayed telephone number circulates in an increment direction or a decrement direction of the recorded incoming telephone numbers one after another.
In the above mentioned display processes (steps 604, 607), only the incoming telephone number information and the incoming time recorded in the incoming; recording memory 121 are displayed. In the event that memory dial information corresponding to the incoming telephone number information is registered in a registering memory 122 which is described later, additional information (e.g. name or company name corresponding to the telephone number) in the memory dial information can be displayed as related information at the same time in addition to the incoming telephone number information.
In this case, in steps 604 and 607, the memory dial information in the registering memory 122 is searched (searching means is not shown) using .a key word of the incoming telephone number which is read out by the incoming record reading means 64.
Then, if the identical telephone number with the incoming telephone number is searched in the incoming record reading means 64, the additional informatian corresponding to the incoming telephone number is read out from the memory dial re;~ding means 68 and displayed on the display portion 13.
Figure 8 is a flow chart illustrating operation of an incoming redialing process using the incoming telephone number recorded in the inconung recording memory 121.
The operation of the incoming redialing process is explained below using Figures 3 and 8. First, in step 801, the operating portion 11 instructs the display portion 13 to display a desired incoming telephone number. The detailed processes from the start to the display indication for displaying the incoming telephone number is the same as the ~~9401 ~_.
to display processes explained using Figure 6. Next, in step 802, the operating portion 11 instructs to carry out the incoming redialing. Then, in a next step 803, the telephone number information read out by the incoming record reading means 64 is transmitted as control information from the radio portion 5 (Figure 1) to the calling party telephone via the control signal processing portion 9 to make a telephone call.
Figure 9 is a flow chart showing an operation of a memory dial registering process of the incoming telephone number recorded in the incoming recording memory 121. In general, a memory dial function includes functions for registering frequently-used telephone numbers and their related additional information (names, names of companies corresponding to the telephone numbers) in advance as memory dial information, for accessing a desired telephone number or additional information, for displaying it and for making a telephone call with fewer operations. The registering is explained using also Figure 3. First, a calling party telephone number is inputted from the operating portion 11. Then, a registering means 65 registers the telephone number into a desired area in the registering memory 122 which is a second memory portion in the memory 12. At this time, it is possible to register the telephone number corresponding to an abbreviated title of the mate name and so on if required.
Figure 10 shows a storage construction of the calling party telephone numbers and the related abbreviation of the mate names. As shown in Figure 10, the telephone numbers are combined with the corresponding abbreviations and registered in respective addresses in the registering memory 122. An operation of the memory dial registering process of the present invention is explained below using Figures 3 and 9. First, in a step 901, a desired incoming telephone number is displayed on the display portion 13 according to the instructions of the operating portion 11. The detailed processes from the start to the display indication for displaying the incoming telephone number is the same as the display processes explained using Figure 6. Then, in a step 902, the operating portion 11 instructs to register the memory dial. In a next step 903, the; telephone number information read out by the incoming record reading means 64 is registered in a desired area in the registering memory 122, or the second memory portion, via the registering means 65.

In Figure 1 a voice processing portion 100 is. shown to comprise A/D converter 2, the voice encoding/decoding portion 3, and the D/A converter 7.
Figure 2 is a functional block diagram relating especially to a recording process of the incoming telephone number conducted in the microcomputer 10 in the system configuration of the digital radio telephone shown in Figure 1. Figure 2 shows a telephone number information detecting means 40 for detecting whether the telephone number information is included in the control information from the control signal processing portion 9; a time information management means 50 for specifying a receiving time of the control information including the telephone number information according to the time from a clock portion (not shown) provided in the digital radio telephone and for outputting the time information; an extension/external line judging means 70 for identifying and judging whether the call is from the extension or from the external line, in case the telephone number information exists, by detecting extension/external line identification information included in the control information for example; an external line information addition means 80 for extracting the telephone number information from the control information and for outputting the telephone number information in the event that the call is from the extension line, while for extracting the telephone number information from the control information, adding external line calling information to the telephone number information, and outputting the telephone number information as new telephone number information in the event that the call is from the external line; and a memory management means 60 for recording the telephone number information from the external line information addition means 80 in the memory 12 (Figure 1) as incoming record information in correspondence to the time information from the time information management means 50.
Figure 3 is a functional block diagram especially relating to a detailed process conducted in the memory management means 60 shown in Figure 2 which is the functional block diagram regarding the incoming telephone number' process conducted in the microcomputer 10. In Figure 3, a telephone number information comparison means 67 compares the telephone number information from the external line information addition means 80 with the telephone number precedingly recorded in the memory and outputs whether these telephone number information are identical to each other. The operating portion 11 gives instructions to compare or not with the; telephone number information. A vacant memory judging means 61 judges whether a vacant area exists in the memory 12 to stare the telephone number information of a new incoming call according to an output of the telephone number information connparison means ("record all" without comparison or "no identical information" as a result of comparison). A rerecording means 62 deletes unnecessary information (the oldest information or a plurality of identical information entries) of the incoming record information recorded in the memory 12 according to a judging result of the vacant memory judging means 61 ("no vacancy") or the output of the telephone number information comparison means 67 ("identical information" as a result of comparison) and keeps vacant areas to newly rerecord the remaining incoming record information. A
~ 9 0 1 ~ .~:
recording means 63 records the telephone number information in a desired area in the memory 12 in correspondence to time information as an incoming record information according to "vacant" as a judging result of the vacant memory judging means 61 or "vacant " as a judging result of the rerecording means 62. Hence, the operating portion 11 causes the display portion 13 to display the telephone number information one after another in a circulative manner beginning with the telephone number information which was most-recently received.
Figure 4 is a flow chart showing an operation of the recording process of the incoming telephone number. The operation of the present embodiment shown in Figure 2 is explained using Figures 3 and 4.
First, in step 401, the telephone number information detecting means 40 detects whether the telephone number information is included in the control information from the control signal processing portion 9. If the telephone number information is not included, the process is completed. If telephone number information is included, in a next step 402 the extension/external line judging means 70 identifies and judges whether the telephone is in the extension or in the external line. If the call is from the external line, in a next step 403, the external line information addition means 80 adds external line identifying information ("0" as the external line calling number, for example) to the telephone number information in the control information. If the call is in the extension, the external line information addition means 80 extracts the telephone number information from the control information and outputs the telephone number information.
Then, in step 404, the time information management means 50 specifies the time when the telephone number information is received. In next step 405, the operating portion 11 instructs the microcomputer 10 whether to record all the same incoming numbers, or only the latest numbers, received form the same calling party, as determined by the user.
If all the identical incoming telephone numbers are to be recorded, the operation goes to step 406. If only the latest incoming telephone number out of the identical incoming telephone numbers is to be recorded, the operation goes to a step 410. In step 410, the telephone number information comparison means 67 compares the latest incoming telephone number information with the incoming telephone number information recorded previously in incoming recording memory 121 (Figure 3) which comprises a first memory portion in the memory 12. If the incoming telephone number information is not identical to the registered telephone number information, the operation goes to step 406.
940 1 ~~~:.
s On the other hand, if the incoming telephone number information is identical to the recorded telephone number information, the operation goes to step 411. In step 411, the recording means 63 deletes the incoming telephone number information recorded previously in the incoming recording memory 121 and goes to a step 408.
In step 406, the vacant memory judging means 61 judges whether the area for new incoming telephone number information in the incoming recording memory 121 can be used. If the incoming recording memory 121 is not occupied, the incoming telephone number information is recorded in the incoming recording memory 121 together with the corresponding time information. If the incoming recording memory :121 is occupied, the operation goes to a next step 407, where the telephone number information with the oldest time information is deleted from the incoming recording memory 121. In the next step 408, second oldest telephone number information is incremented and recorded into the location in the incoW ing recording memory 121 where the oldest time information is deleted. This operation is repeated continuously. In a next step 409, latest incoming telephone number information is finally recorded together with the time information into a location in the vacant incoming recording memory 121, following which the operation is completed. Figure 5 shows a memory arrangement of the incoming telephone numbers and their incoming times in the incoming recording memory 121. As shown in Figure 5, the respective incoming telephone number is stored in each address in combination with its incoming time in the incoming recording memory 121.
Figure 6 is a flow chart depicting operation of display processes associated with recordal of the incoming telephone number in the incoming recording memory 121. The operation of the display processes is explained below using Figures 3 and 6.
First, in step 601, in response to user input, the operating portion 11 instructs to display the incoming telephone number. In next step 602, a memory record judging means 66 judges whether incoming telephone number information is recorded so far into the incoming recording memory 121. If no incoming telephone number information is recorded so far, in step 603, a warning sound is given from the spealker 8 to inform that no incoming telephone number information is recorded and also a warning indication is displayed on the display portion 13, whereupon, the display process is completed. If the incoming telephone number information is recorded, an incoming re~~ord reading means 64 reads an incoming telephone number received most recently together with its incoming time out of the incoming recording memory 121, and in step 604, the display 2~~~~ ~ ~~
portion 13 displays the telephone number and the incoming time. In next step 605, the display process finishes according to an instruction of the operating portion 11. For displaying other incoming telephone numbers, in next step 606, the operating portion 11 instructs to switch the display indication of the incoming telephone number.
In response to the instruction from the operation portion 11, in step 607, the display of an immediately preceding incoming telephone number or an immE:diately succeeding incoming telephone number is switched back and forth. After that, the operation returns to the step 605. Steps 605, 606, 607 are then repeated until a desired incoming telephone number is displayed.
Figure 7 shows a displaying order of the incoming telephone numbers when five incoming telephone numbers are recorded. According to the instructions from the operating portion 11, the displayed telephone number circulates in an increment direction or a decrement direction of the recorded incoming telephone numbers one after another.
In the above mentioned display processes (steps 604, 607), only the incoming telephone number information and the incoming time recorded in the incoming; recording memory 121 are displayed. In the event that memory dial information corresponding to the incoming telephone number information is registered in a registering memory 122 which is described later, additional information (e.g. name or company name corresponding to the telephone number) in the memory dial information can be displayed as related information at the same time in addition to the incoming telephone number information.
In this case, in steps 604 and 607, the memory dial information in the registering memory 122 is searched (searching means is not shown) using .a key word of the incoming telephone number which is read out by the incoming record reading means 64.
Then, if the identical telephone number with the incoming telephone number is searched in the incoming record reading means 64, the additional informatian corresponding to the incoming telephone number is read out from the memory dial re;~ding means 68 and displayed on the display portion 13.
Figure 8 is a flow chart illustrating operation of an incoming redialing process using the incoming telephone number recorded in the inconung recording memory 121.
The operation of the incoming redialing process is explained below using Figures 3 and 8. First, in step 801, the operating portion 11 instructs the display portion 13 to display a desired incoming telephone number. The detailed processes from the start to the display indication for displaying the incoming telephone number is the same as the ~~9401 ~_.
to display processes explained using Figure 6. Next, in step 802, the operating portion 11 instructs to carry out the incoming redialing. Then, in a next step 803, the telephone number information read out by the incoming record reading means 64 is transmitted as control information from the radio portion 5 (Figure 1) to the calling party telephone via the control signal processing portion 9 to make a telephone call.
Figure 9 is a flow chart showing an operation of a memory dial registering process of the incoming telephone number recorded in the incoming recording memory 121. In general, a memory dial function includes functions for registering frequently-used telephone numbers and their related additional information (names, names of companies corresponding to the telephone numbers) in advance as memory dial information, for accessing a desired telephone number or additional information, for displaying it and for making a telephone call with fewer operations. The registering is explained using also Figure 3. First, a calling party telephone number is inputted from the operating portion 11. Then, a registering means 65 registers the telephone number into a desired area in the registering memory 122 which is a second memory portion in the memory 12. At this time, it is possible to register the telephone number corresponding to an abbreviated title of the mate name and so on if required.
Figure 10 shows a storage construction of the calling party telephone numbers and the related abbreviation of the mate names. As shown in Figure 10, the telephone numbers are combined with the corresponding abbreviations and registered in respective addresses in the registering memory 122. An operation of the memory dial registering process of the present invention is explained below using Figures 3 and 9. First, in a step 901, a desired incoming telephone number is displayed on the display portion 13 according to the instructions of the operating portion 11. The detailed processes from the start to the display indication for displaying the incoming telephone number is the same as the display processes explained using Figure 6. Then, in a step 902, the operating portion 11 instructs to register the memory dial. In a next step 903, the; telephone number information read out by the incoming record reading means 64 is registered in a desired area in the registering memory 122, or the second memory portion, via the registering means 65.
