作は省略する。）。FIG. 1 shows an example of this conventional method. In the figure, a terminal device Q 11 has a transmitter (TX) 12 and a receiver (RX) 13 of a wireless base station, and a channel control device 17.
and another subscriber 18 on the call path 14, 19.20 via
Suppose you are on a call with . When the terminal device 11 goes out of the service area of the assigned channel, the electric field of the communication channel 14 decreases, is detected by the detection GIY (R) 15, and a channel switching request signal 16 is sent to the channel control device δ17. Sent. Based on this channel switching request signal, the channel control device fi 7 side initiates an operation to allocate a communication channel within an optimal wireless zone (this operation is omitted).

By configuring the island I4 terminal device side with a channel cut-off/request switch and a channel switching request signal sending function of 11γ, the channel switching operation, which was conventionally controlled only by the unused I base station, can be realized. Qrli's first function can also be used as a Qrli accessory.
f7, channel switching can be realized by the judgment of the subscriber (person), and i! which cannot be detected automatically. It has the effect of preventing a decline in the quality of f7 episodes. According to the present invention, it is possible to detect faults in communication systems that cannot be detected electrically.
