发明名称 Mobile communication system capable of performing soft-handover between base station controllers connected to different mobile communication exchanges
摘要 A mobile communication system comprises connection lines as communication lines and a control signal line for transmission/reception of a control signal between base station controllers. In soft-handover control sections arranged within the base station controllers, respectively, the connection lines are established with reference to received electric field strength at a mobile terminal. Switching sections arranged within the base station controllers, respectively, perform path-connection among the communication lines, the soft-handover control sections, a QCELP/PCM conversion section of communicating base station controller, the connection lines, and the control signal line.
