PURPOSE:To obtain a transmission channel control method having priority not saturated at a steady-state by storing a transmission successful probability to each channel in each system, using a channel having a high transmission success probability sequentially in the transmission and revising the success probability depending on the result of transmission. CONSTITUTION:When a call request signal from an input terminal 102, a processor 50 sets a channel number having the highest priority to a synthesizer 40. The synthesizer 40 outputs the signal of a corresponding carrier frequency and multiplies it with a reception signal received from an input terminal 100 by a multiplier 10. An intermediate frequency signal outputted from the multiplier 10 is inputted to a power detector 20 to detect the reception power. The output of the power detector 20 is inputted to a deciding circuit 30 to decide whether or not a line is idle and the deciding circuit output is inputted to the microprocessor 50. When the circuit 30 decides that the line is in use, the microprocessor sets the next channel to the synthesizer 40 and revises a priority function based on the output of the deciding circuit 30. |
