Description of the Preferred Embodiment With reference to FIG. 1, an electrical block diagram of a selective call receiver 101 is shown coupled to an external computer 103 in accordance with the preferred embodiment of the present invention and comprises an antenna 102 for intercepting RF signals. The antenna 102 is coupled to a receiver 104 for receiving and demodulating the RF
signals intercepted. A decoder 106 is coupled to the receiver 104 for decoding demodulated address information.
A microprocessor 108, e.g., the 68HC05C8 or Cll manufactured by Motorola, Inc. of Schaumburg, IL, is also coupled to the receiver 104 for processing the demodulated information to recover messages. The microprocessor 108 is coupled to a random access memory (RAM) 110 for storing the messages recovered, and the microprocessor 108 controls the storing W094/09569 2 1 ~ 7 2 5 ~ 4 PCT/US93/09141 and recalling of the messages. An alert generator 112 is coupled to the microprocessor 108 for providing an audible or tactile alert to a user when the microprocessor 108 has a message ready for presentation.
An output device 114 comprises a visual display or a speaker or both, the output device 114 also being controlled by the microprocessor 108. The control section 116 comprises user accessible controls for allowing the user to command the microprocessor 108 to perform the selective call receiver operations well known to one of ordinary skill in the art and typically includes control switches such as an on/off control button, a function control, etc.
The microprocessor 108 is coupled to a read-only memory (ROM) 121 and a data interface 118 for controlling and communicating with the ROM 121 and the data interface 118, in accordance with the present invention. The ROM 121 comprises two special-purpose elements in accordance with the present invention. An external computer detect element 140 comprises firmware for detecting the presence of an external computer in response to a signal received by the data interface 118. A control transfer element 142 includes a transfer request element 144 containing firmware for requesting transfer of control of the selective call receiver to the external computer. The control transfer element 142 also includes a transfer completion element 146 comprising firmware for transferring to the external computer 103 control of functional elements listed in a response from the external computer 103.
The data interface 118 is constructed and controlled in a manner that meets the well-known Personal Computer Memory Card International Association (PCMCIA) standard interface.
The data interface 118 couples with the external computer 103 by a PCMCIA bus 119. One of ordinary skill in the art will recognize that other types of parallel interfaces could be used as well.
The external computer 103, e.g., the HP95LX computer manufactured by Hewlett Packard, Inc. of Palo Alto, CA, comprises a data interface 128 also of the PCMCIA type 21~72S~
W094/0956g ~ PCT/US93/09141 coupled to a microprocessor 120 for communicating with the PCMCIA bus 119. The microprocessor 120 is coupled to a display 122, typically an LCD type, and a keyboard 124 for interfacing with a user. A read-only memory (ROM) 126 is coupled to and controlled by the microprocessor 120 for storing software instructions and other pre-programmed information used by the external computer 103. A random access memory (RAM) 130 is also coupled to the microprocessor 120 for storing software programs and other values received from the microprocessor 120. The RAM 130 has been programmed with transfer of control software 132 comprising functional element identifiers 134 identifying functional elements, e.g., address decoding or message handling, that the transfer of control software 132 is able to perform.
With reference to FIG. 2, an isometric view of the selective call receiver 101 in accordance with the preferred embodiment of the present invention depicts a connector comprising the PCMCIA bus 119 for interconnecting with the external computer 103 (FIG. 1). Also depicted is a control button of the control section 116.
With reference to FIG. 3, an orthographic view of the selective call receiver 101 coupled to the external computer 103 in accordance with the preferred embodiment of the present invention depicts the selective call receiver 101 fully inserted into a PCMCIA receptacle 304 of the external computer 103. In this position, the electrical coupling provided by the PCMCIA bus 119 ( FIG. 1) allows the external computer 103 to assume some or all the control of the selective call receiver 101 in accordance with the present invention.
With reference to FIG. 4, a flow chart depicts the operation of transfer of control from a processor internal to the selective call receiver 101 (FIG. 1) to the external computer 103 (FIG. 1) in accordance with the preferred embodiment of the present invention. The process begins with the external computer 103 being programmed 402 with software compatible with the transfer of control in W094/09569 2 ~ ~ 7 ~ 5 0 PCT/US93/09141 accordance with the preferred embodiment of the present invention. A portion of the software includes the functional element identifiers 134 (FIG. 1) that will identify to the microprocessor 108 (FIG. 1) of the selective call receiver 101 those functional elements of the selective call receiver 101 that the software can perform.
Next, the respective data interfaces 118, 128 of the selective call receiver 101 (FIG. 1) and the external computer 103 (FIG. 1) are coupled 404 together. The selective call receiver 101 senses 406 the coupling from a signal, e.g., a voltage level, supplied to the PCMCIA bus 119 (FIG. 1) by the external computer 103 and in response queues a transfer request message to be sent over the PCMCIA
bus 119. The microprocessor 120 (FIG. 1) of the external computer waits 408 for the transfer request message, after which the microprocessor 120 sends 410 a list of the functional element identifiers 134 identifying the functional elements of control that the external computer 103 has been programmed to assume from the selective call receiver 101. After receiving the list sent in step 410 the selective call receiver 101 terminates 412 control of the listed functional elements, and the external computer 103 assumes 414 control of the listed functional elements through the PCMCIA bus 119. The process ends thereafter in step 416.
For the case in which one of the functional elements to be transferred to the external computer 103 (FIG. 1) is the processing of certain types of message, e.g., information service or mail drop messages, then message processing will be either transferred or not transferred, based upon message type. For example, a perfectly valid scenario would be to set up the transfer of functional elements such that individual personal messages are processed by the microprocessor 108 of the selective call receiver 101 (FIG. 1), while the typically much longer information service or mail drop messages are processed by the external computer 103.
Thus, the present invention advantageously provides a method and apparatus for adding new features and options to a portable radio communication device without having to physically replace software storage elements of the portable radio communication device. This ability reduces the cost of both material and labor for field upgrades of software.
Also a way is provided for adding new features and custom application software that will not severely degrade the battery life of the portable radio communication device.
This is so because the present invention allows all software requiring either large amounts of storage or high speed memory to be executed external to the portable radio communication device, thus advantageously removing items associated with high power drain and hence conserving the battery of the portable radio communication device.
