PROBLEM TO BE SOLVED: To realize an incoming call voice with respect to a voice data common use terminal equipment so as to inform a voice incoming call message using a packet channel by a base station when a voice incoming call is received by a voice data common use equipment awaiting a packet call in the packet channel. SOLUTION: When a voice incoming call from a communication opposite party 107 is received by a voice data common use terminal equipment 101 awaiting a packet through a packet channel, a base station controller 103 detects the voice incoming call and calls the voice data common use terminal equipment through a control channel via a base station 102A. When no incoming call reply is received from the terminal equipment 101 even after the elapse of a prescribed time, the base station 102A discriminates that the terminal equipment 101 acquires the packet channel and sends a packet informing the voice incoming call to the terminal equipment 101 through an outgoing packet channel. The terminal equipment 101 receiving the packet moves from the packet channel to the control channel and makes a voice incoming call by using the control channel afterward. |
