At the time of standby (F2-1), the radio units 2 and C
The outside of the service area and the service area are always determined based on the information from the H codec unit 3 (F2-2).
The control channel search cycle is normally set (F2-4), for example, 10 seconds. (The control channel search cycle will be described in the description of FIG. 8.

Initialization of the out-of-service continuation timer thereunder (F2-
5) is a process added only when the control of claim 4 is performed, and initializes a timer for counting continuation outside the service area.

If it is out of the service area (F2-2), the control channel search cycle delay processing (F2-3) according to each claim is performed.

This processing is a subroutine, and differs according to each claim.

FIG. 3 shows a control method in the first embodiment.

FIG. 4 shows a control method in the second embodiment.

FIG. 3 or FIG.
Control method can be performed.

FIG. 3 shows a subroutine of the control channel search cycle extension process of the first embodiment.

It is determined whether the current time is nighttime or daytime based on the information of the clock function in the control unit 4.

(F3-1) The night time to be determined is determined, for example, from 11:00 p.m. to 8:00 a.m. This setting may be freely determined.

If it is daytime according to the time determination, the control channel search cycle is normally set (F3-3).

For example, the search period is extended in a specific time zone such as at night, but the extension time at that time is set by a subroutine because the method of setting differs depending on each claim (F3-2).

In the first and second aspects, FIG. 5 shows an extended time setting method.

FIG. 6 shows an extended time setting method.

FIG. 7 shows an extended time setting method.

FIG. 5 shows an extended time setting method since the present invention is described in claim 1, and the control channel search time is set longer than usual. For example, if the normal time is 10 seconds, the extension time is set to 20 seconds.

FIG. 4 shows a subroutine of the control channel search time extension processing according to the second aspect. The determination of the schedule time is based on (F4-1) the extension processing start time (K1 in FIG. 10, K1) of the out-of-service search cycle extension processing in which the time from the clock function of the control unit 4 is stored in the storage unit 6. It is determined whether or not the time is within the end time (K2 in FIG. 10).

If it is out of the range, the control channel search cycle is set normally (F4-3).

If it is within the range (same processing as F2-4, F3-3), an extended time setting process (F4-2) is performed.

This processing is the same as that described in the first embodiment with reference to FIG. 3. In the second embodiment, FIG. 5 is an extended time setting method, which is the same as the above description.

FIG. 6 shows an extended time setting method according to a third aspect, in which the extended time setting of the search cycle is changed according to the extended time (FIG. 9) stored in the storage unit 4.

(F6-1) If the stored extension time is time 1, the control channel search time is set to time 1.

Time 1 is, for example, 20 seconds.

If the extension time is time 2, the search time is set to time 2.

Time 2 is, for example, 30 seconds.

FIG. 7 shows an extended time setting subroutine according to the fourth aspect.

In the present invention, the out-of-service time is counted (F7-1).

Next, the out-of-service time count value is determined (F7-2), and when the out-of-service time count value reaches a predetermined set time, for example, 10 minutes or more, the control channel search time is extended (F7-3).

This method is the same as (F5-1) in FIG.

If the time is within the set time, the search time extension process is not performed, so the control channel search time is normally set.

(F2-4) in FIG. 2 and (F3-
3), a method similar to (F4-3) in FIG.

As described in FIG. 2, the out-of-service time count value is returned to the initial value by initialization in the service area.

That is, the control channel search time is not extended under the condition that the in-service area and out-of-service area are repeated within the set time of 10 minutes (the boundary between the in-service area and the out-of-service area).

FIG. 8 shows a specific example of the control channel search time when out of the service area.

In the public mode, usually 11 every 10 seconds
A control channel search is performed for 0 ms.

Other than 110 mS search ON, the search is turned OFF and the mode is the low power consumption mode.

That is, the longer the control channel search time in the out-of-service area, the lower the current consumption.

The extension of the control channel search cycle is 10 seconds to 2
This is set to 0 seconds, and the extension time can be freely set to 10 seconds or more.

FIG. 9 is a configuration diagram of an area for storing an extended time according to the third embodiment. In this example, the extension time is set to time 1
(For example, 20 seconds) and time 2 (for example, 30 seconds).

A plurality of extension times can be set, and the value of the extension time can be freely set.

The control unit 4 receives the information from the key operation unit 5 in FIG.
