RADIO COMMUNICATION DEVICE

摘要

PURPOSE:To carry on a communication by a time-division multiplex system moving body system without disconnecting a radio line even in the case of asynchronous interference by performing switching to a predetermined stand-by channel if the asynchronous interference is detected. CONSTITUTION:In the time-division multiplex system moving body system which constitutes a multi-zone by plural radio connecting devices and have a communication with plural mobile equipments, each radio connecting device is provided with an asynchronous interference detection part 107 which can detect the asynchronous interference, and a stand-by channel for asynchronous interference evasion is prepared and reported to the mobile equipments together with a communication signal. A communication channel control part 106 detects the asynchronous interference, and switches the channel to a communication channel previously set for free carrier information when the asynchronous interference is detected. Each mobile equipment detects the unreceivable state of the communication signal which can be received so far and switches the channel to the previously reported communication channel. Consequently, the radio line can be prevented from being disconnected.
