The control unit 19 is constituted by a microcomputer having a built-in ROM and RAM, and controls communication and the like by executing various programs in the ROM. In particular, when the CS-ID detected by the control channel capturing process matches the CS-ID of the registration destination parent device, the control unit 19 selects the parent device as the parent device that performs transmission and reception.

More specifically, the control unit 19 includes an ID memory 19
1 and a selection ID memory 192. ID memory 19
1 is the CS-I received from the parent device at the time of registration of the child device.
D is stored up to three. The selected CS-ID is currently
The CS-ID of the parent device selected as the parent device that the child device 10 transmits and receives is stored.

First, the control unit 19 selects the CS-ID from the control information received by the control channel monitoring process.
And its reception level. Here, the control channel monitoring process is started when one child device 10 goes out of the range of the registered parent device, and the first three minutes are every five seconds, and the next seven minutes are every ten seconds. , And thereafter, at intervals of 28 seconds, thereby suppressing power consumption.

FIG. 3 is a diagram showing the parent devices 301 to 303 of the registration destination stored in the ID memory 191 of the child device 10 and their wireless zones R 301 to 303. Here, it is assumed that the CS-IDs of the parent devices 301 to 303 are 301 to 303. Reference numeral 310 denotes A by the user who carries the handset 10.
From D to D. While the slave 10 moves from A to B in FIG. 3, 301 is stored in the selected ID memory 192 as CS-ID. For this reason, the child device 10 is
Outgoing / incoming calls via the Internet.

Next, when the handset 10 passes B, the control unit 1
9 is detected to be out of the range of the wireless zone R301 of the base unit 301, and the processing shown in FIG. 2 is started. While the slave unit 10 moves from B to C, the control unit 19 monitors the control channel (step 201), and receives the CS-ID in the received control information and the reception level input from the RSSI detection unit 123. Is detected (step 202).

The control unit 19 determines whether the detected CS-ID matches the CS-ID in the ID memory 191.
A search is made as to whether or not there is (step 203). As a result of the search, it is determined that there is no matching CS-ID, and the monitoring process ends (step 204). Thus, the control unit 19
Is the interval of 5 seconds for the first 3 minutes between BC and
The above process is repeated at intervals of 10 seconds for minutes and thereafter at intervals of 28 seconds.

When the slave 10 has passed C, the control unit 19
Is determined by monitoring the control channel (step 20).

The data is stored in the D memory 192. The control unit 39 selects the selection ID
Sending and receiving is performed via the CS-ID master unit stored in the memory 192.

The processing of the control unit 39 is summarized in FIG.
It becomes like the flowchart of FIG. The processing shown in the figure will be described below using the example of FIG. When the slave 30 passes the position C in the direction D in FIG.
Detects the CS-ID and the reception level by monitoring the control channel (steps 801 and 802). Here, the control unit 39 detects the CS-IDs 302 and 303, and receives the corresponding reception levels 40 dB and 2 dB.
0 dB is detected.

The control unit 39 determines that there is no CS-ID having the first priority among the CS-IDs (step 803), and proceeds to the processing of step 806. Control unit 3
9 determines that there is a CS-ID 303 with the second priority (step 806), and then determines whether the reception level is equal to or higher than a predetermined level (30 dB) (step 807). As a result of the determination, the CS-ID 303
Is 20 dB, and therefore does not exceed a predetermined level. Accordingly, the control section 39 proceeds to the processing of step 809.

The control unit 39 controls the CS having the third priority.
-It is determined that the ID 302 exists (step 809),
Next, it is determined whether or not the reception level of the CS-ID 302 is equal to or higher than a predetermined level (step 810). As a result of the determination, since the reception level of the CS-ID 302 is 40 dB, it is determined that the reception level is equal to or higher than the predetermined level. The control unit 39 controls the CS-
The ID 302 is stored in the selected ID memory 192 (step 811).

As described above, the control unit 39 selects the registered CS-ID detected at the place, which has a higher priority and whose reception level is equal to or higher than a predetermined level, and selects the selected CS-ID. , And thereafter make and receive calls from the master unit. With this configuration, the child device 30 in the present embodiment can select the user's CS-ID from the CS-ID whose reception level exceeds a predetermined level, that is, the CS-ID of the parent device that enables more stable communication without user operation. A desired parent device is preferentially selected, and transmission / reception is performed via the parent device.
