Ｉｉ七なる欠点を有していた。Figure 1 shows approach lines 2 and 2 under one control station 1.
tied together. This is a simplified line configuration diagram of a base station 3I, base station 32, . . . , base station 3n of a plurality of multi-channel access radio lines. Conventionally, the radio frequencies for multi-channel access lines transmitted from these base stations 31 to 3n are as shown in the figure (in the example in Figure 1, each base station 3
c) Indicates the case of i) Base station 31 is on the same wave number right, f2+
13+ base station 32 is f4. f5. f6゜base station n
All channel frequencies were given differently for each base station, such as Hf3n-2+f3n-]+13n. However, now, in addition to the multi-channel access type fixed station, the service area of each base station 31 to 3n is provided in the same system! Therefore, when incorporating a mobile terminal station that can move freely, the mobile terminal is equipped with a channel switching transceiver 5 capable of switching all channels of all base stations and a channel switching transceiver 5 for controlling the channels, as shown in FIG. channel control unit 6, the equipment configuration of the mobile terminal station becomes complicated, and the cost is high.
It had seven drawbacks.
本発明はこれらの欠点を除去するため、基地局の周波数

。FIG. 3 shows an embodiment of the present invention. The same numerals as in Figure 1 indicate the same product names. As shown in the figure, by applying the same i=line frequency f to one channel out of the plurality of channels assigned to each base station 31 to 3n, the same i=line frequency f is applied to each base station, as shown in FIG. , these ノ, 1ya 1::33+
Mobile terminal stations that move freely across the ~3n noise area (are two frequencies f, and are equipped with one channel transmitter/receiver 7) can perform complex control such as channel control. It is possible to secure communication while freely moving within the service area of each base station 31 to 3n.

By simply equipping a channel radio, communication within the service area of all base stations becomes possible, and the configuration of the mobile terminal station can be extremely simplified.
