COMMUNICATION CHANNEL SWITCHING SYSTEM IN MOBILE COMMUNICATION |
摘要 |
PURPOSE:To attain the changeover independently of a central controller by providing a means measuring a reception level of a radio wave from a mobile equipment and sending the level to the mobile station and a communication channel changeover means to a base station and providing a means returning the information of a reception level from the base station during communication to the mobile equipment. CONSTITUTION:A reflected signal from a mobile equipment is demodulated by a reception level measuring receiver 21 and reaches a controller 22. Then the reception level measuring receiver 21 measures a reception level and informs the result to the controller 22 via a demodulation signal interconnection 26. The controller 22 compares level information A in the reflected signal from the demodulation signal interconnection 25 with level information B from a demodulation signal interconnection and in the case of A<B, it is discriminated that the mobile equipment is moving to its own zone. When it is discriminated that plural base stations are moved to their own zones, a base station with the largest value of B-A is discriminated to be final destination and switching over of the busy channel is assigned to the base station. |
