Referring to FIG. 3, it is an electrical block diagram of the portable subscriber unit 122 according to a preferred embodiment of the present invention, which includes a transmitting antenna 302 to transmit RF signals to the base station 116, and a receiving antenna 305 to receive HF signal of base station U6. The transmitting antenna 302 is coupled to a conventional transmitter 304, and similarly, the receiving antenna 305 is coupled to a conventional receiver 306. Receive the received base station n6 as the FSK signal of layer 2 and 4. The RF signal transmitted by the portable subscriber unit 122 to the base station 116 is transmitted as a 4-layer FSK signal. The wireless signal received by the receiver 306 produces demodulated information at the output. The input of the demodulation information link processing unit 3 1 0 processes the output message. Similarly, the input approval message is processed by the processing unit 310 and transmitted to the transmitter 304 for transmission. A conventional power switch 308 connected to the processing unit 310 controls the power supplied to the transmitter 304 and the receiver 306, thereby providing a battery saving function. In order to perform the necessary functions of the portable subscriber unit 122, the processing unit 31 includes a microprocessor 316, a RAM 312, a ROM 314, and an EEPROM 318.

Description of invention (8) R0M3 14 is used to plan the microprocessor 316 to process the input message on the output channel to generate the approval message on the input channel .When processing the output message, the microprocessor 3 16 samples the demodulated signal generated by the receiver 306 The microprocessor 3 16 then decodes the address in the demodulated data of the output message, compares the decoded address with one or more addresses stored in the EEPROM 3 18, and when the layering is sensed, the microprocessor 316 continues to execute the remaining messages. Once the microprocessor 3 16 has processed the message, it stores the message in the RAM 312 and generates a call warning signal to warn the user that a message has been received. The call warning is sent to a The conventional audible or tactile warning device 322 generates an audible or tactile call warning signal. In addition, the microprocessor 3 16 plans to send ACK or NAK according to the quality of the received message. In order to send out the approval, the microprocessor 316 controls the transmitter 3 04 Modulation circuit (not shown) to send FSK data corresponding to the approval message. The user uses the output message through the user controller 320, which provides functions such as lock, 'open, delete, read, etc. More particularly , By using the appropriate function provided by the user controller 320, the message can be recovered from the raM3 12, and then displayed on the display 324 such as a conventional liquid crystal display (lc D) It can be displayed in an audible manner, if it is a voice message, it can be broadcast in a combined manner of audio amplifier 326 and speaker 328. The microprocessor 316 is also planned to receive the first sub-region color code from the receiver 306. The microprocessor 3 16 continues to store the first color code in the RAM 3 12. During the sub-range conversion, the receiver 306 generates a second sub-region color code corresponding to the second sub-region, which is completely different from the first sub-region.

Description of the invention (9. Receive losses and continue to scan and register the control channel table. The boarding control channel table preferably contains 4 registered control channels, which correspond to 4 sub-zones, and the color codes of the sub-zones in each sub-zone are the same as the case of the fixed part 102 of the wireless communication system described above. The control mine track table is limited to 4 registered control channels to provide the portable subscriber unit 122 with a method of quickly finding the control channel, thereby reducing the portable subscriber unit 122 registration delay. Or it will be understood that the same registration control channel can be used on the four sub-zone color codes. In another Zhao example, the microprocessor 316 controls the receiver 306 to scan a set of preset control channel frequencies, which are given by the fixed part 102 of the wireless communication system to obtain control information in response to the above Loss of control information received in the sub-area (ie the first sub-area). In this specific example, EpproM3 j 8 uses the control channel table used by the fixed part 102 of the wireless communication system to plan the user unit 122. This list is usually large and therefore causes a delay in the portable subscriber unit 122. Once the portable subscriber unit 122 has locked the control channel when receiving loss, the microprocessor 316 compares the color codes of the first and second sub-areas to check the difference of the color codes of the sub-areas. When a mismatch is sensed, the microprocessor 316 continues to register the portable subscriber unit 122 with the second sub-region corresponding to the second sub-region color code in response to the mutually different first and second sub-region color codes . In this case, the portable subscriber unit 122 sends a registration request to the base station 116 in the second sub-zone. When the broadcast subscriber unit 122 receives the registration approval of the base station 116, the controller 112 of the portable subscriber unit 122 indicates that the approval message has been approved as the registration unit in the second sub-zone. The approval message can also include a control channel that is different from the control channel that is identified and registered, which is selected by the controller 112 and is applicable to the Chinese national standard falcon (CNS & A4 specifications (21〇 × 297 mm) in 12-sheet format (please first Read the precautions on the back and then fill out this page) Pack.

Invention description (A match is detected. In step 708, the portable subscriber unit 122 registers the second sub-region corresponding to the color code of the second sub-region In response to the situation where the color codes of the first and second sub-regions are different. In step 710, the portable subscriber unit 122 sends a registration request to the controller 112. In step 712, the portable subscriber unit 122 waits for the controller 112 to approve , It recognizes the registration of the portable subscriber unit 122 in the sub-area. After the portable subscriber unit 122 waits for a preset time, if no approval is received within this time, the portable subscriber unit 122 jumps to step 710, Here, the registration request is retransmitted. If the attempted retransmission exceeds the retransmission count (not shown), the user unit 122 can suspend the transmission of the registration request. If the base station 116 receives the approval within the preset time, then The portable subscriber unit 122 jumps to step 704, where it continues to monitor the transition of the sub-area 402. Therefore, it should now be understood that the present invention provides a method and apparatus that facilitates tracking the position of the portable subscriber unit 122.
