Abstract

PROBLEM TO BE SOLVED: To enable a user to confirm identification information that is recognized between a master set and a slave set through exchange of the identification information when the user registers the identification information and to display the recognized identification information. SOLUTION: A CPU 206 of a master set 102 displays identification information(ID) of a slave set to a display part 209 at registration of the slave set. Then the CPU 206 selects whether the ID is written in an EEPROM 201 or not. Furthermore, the date and time when the ID is registered is registered in the EEPROM 201 corresponding to the ID and afterward the registered date and time are displayed. Furthermore, in the case that communication using the ID is conducted, a communication history for every ID is also registered corresponding to the ID and the communication history is later displayed. Furthermore, when a specific ID stored in the EEPROM 201 is in use, warning is raised.

FIGS. 6 and 7 are ID registration sequence diagrams between the master unit and the slave unit. The ID registration process will be described with reference to this sequence diagram.

First, when the user presses the 401 registration key of the 102 base unit, the 206 CPU of the base unit detects the key press via the 212 keypad (601), and sets the base unit to the registration mode. This mode is managed by providing a flag for managing the mode in the 208 RAM (602). Upon completion of the mode setting, the apparatus enters a state of waiting for ID reception from the slave unit (603). In this state, the 206 CPU of the master unit receives the data from the slave unit so as to receive data on the control channel.
11 transmission / reception circuits are set so that they can be received by the control channel.

The slave unit 1 is the slave unit 1 to be registered by the user.
Is pressed, the CPU 306 of the slave unit is pressed.
Detects this pressing (651), puts the child device 1 into the registration mode (652), and waits for the call key to be pressed (65).
3). Here, before the handset waits for the call key to be pressed,
The master unit is in a state of waiting for ID reception.

Thereafter, when the talk key of the slave unit is pressed, the CPU 306 of the slave unit detects this (654), and
The ID registration message is transmitted to the master unit through the control channel (655).

This message includes a code indicating an ID registration request and information on the ID to be registered. This ID was written in the 313 EEPROM during the production of the slave unit. The CPU of the slave unit reads the ID from the EEPROM, attaches a registration request code, and corrects the error on the receiving side with the 304 error correction circuit. Data processing is performed so that the data can be restored, the data is subjected to framing processing in a 303 baseband processing unit, modulated in a transmission / reception circuit 302, and transmitted on radio waves. Before transmission, a detection unit in the transmission / reception circuit 302 checks whether the control channel is being used by another wireless device.

Upon transmission, the handset 1 sets the transmission / reception circuit 302 to be able to receive data on the control channel in order to receive the DI confirmation message from the base unit, and waits for confirmation (656). For wireless transmission, a general multi-channel access method may be used.

When the detection unit detects the control channel frequency, the 211 transmission / reception circuit of the master unit receives the data, demodulates the data, performs the deframing process in the baseband processing unit 207, and corrects the error. The circuit performs error correction processing and receives ID registration ID data (60

The data is stored in the RAM, processed in a format that can be displayed on the 209 display unit, and displayed (605). When displayed, 206CP
U waits for the user's confirmation, and presses 402 confirmation key 2
It waits for detection from the 12 keypad (606).

When the 206 CPU detects that the 402 confirmation key has been pressed by the user (607), the 202R
The ID information temporarily stored in the AM and the date and time of registration read from the real-time clock 213 are set to 201
The data is written into the EEPROM (608), and an ID confirmation message is transmitted to the child device 1 (609). This message is
It contains information of only a code indicating that D has been registered. The transmission of this message is performed by controlling the transmission / reception circuit, the baseband processing unit, and the error correction circuit in the same manner as shown in the slave unit.

If the user presses the 404 cancel key instead of the 402 confirmation key, a message indicating that registration is not possible is returned to the slave unit, and registration is not performed.

After transmitting the ID confirmation message, the master unit presses the registration key or waits for reception of the next ID registration message (610). Here, if one ID of the slave unit is stored, 20
The counter indicating the number of registered IDs stored in one EEPROM is counted up by one.

The handset 1 which has been waiting to receive the ID confirmation message receives the ID confirmation message (657), and transmits an ID registration end sound to notify the user that the registration has been performed (658). Then, the ID registration mode of the child device 1 is terminated (659).

When only registration of the slave unit 1 is performed,
Here, the registration key of the parent machine is pressed, and the registration mode of the parent machine is also terminated (619). When the ID of the child device 2 is also registered as in the example, the parent device repeats the processes 611 to 618 as in the case of the child device 1. Slave device 2 performs the same processing as slave device 1 (6
60 to 668) and register.

Next, the storage ID display and confirmation erasure processing of the master unit will be described with reference to FIG. The 206 CPU of the 102 parent machine is 212
The signal from the keypad is checked, and the process waits until the 403 ID display key is pressed (701). When the 403 ID display key is pressed, the number of IDs stored in the 201 EEPROM is checked (702), and when the stored number is displayed, both the upper and lower parts of the display are cleared (709), and this processing is performed. To end. To control the number of display IDs, the number of storage IDs stored in the 201 EEPROM is read, and the information is stored as a variable in the 208 RAM,
Every time one ID is displayed, if it counts down from that variable by one and becomes zero, the control is performed as if all the IDs were displayed.

If not all IDs have been displayed yet,
The ID that is not displayed and the information on the year, month, day and time storing the ID are read from the 201 EEPROM (703).
The read information of the registered date and time is displayed on the upper part of the display unit 209 and the ID is displayed on the lower part (704).

When displayed, the 206 CPU checks whether the 406 check ID key has been pressed (705).
It is stored in one EEPROM (706). Here, when communication is requested by the ID after being specified as the check ID, the master unit 102 performs control so as not to perform the communication but to sound an alarm sound.

Next, it is checked whether the delete key 404 has been pressed (707). If the key has been pressed, the information related to the ID is deleted from the 201 EEPROM, and 1 is determined from the number of registered IDs.
Decrement (708). Then, it is checked again whether the ID display key has been pressed.

Here, the display of the ID is displayed on the 209 display unit.
The D information may be output to a printer.

The communication time may be displayed instead of or together with the registration date and time.

It waits for a notification of the reception of the UA 803, which is a link establishment notification, from the / f processing unit (1202). Upon receiving the UA from the line, the 206 CPU allocates a wireless link channel to the slave unit that has requested wireless link establishment 804 (1).
203). Until this wireless link assignment, both the master unit and the slave unit perform communication by setting the transmission / reception circuit units 211 and 302 to the frequency of the control channel. When the channel assignment is completed, thereafter, the transmission / reception circuit unit is set so as to shift to the communication channel assigned to both the master unit and the slave unit, and the communication is continued.

The CPU shifts to the communication channel and waits for the reception of the call setting message 805 from the slave unit (1).
