COMMUNICATION RADIO CHANNEL DETERMINATION METHOD FOR MOBILE RADIO COMMUNICATION STATION

摘要

PROBLEM TO BE SOLVED: To select and set a radio channel which is best suited for a requested service among plural radio channels and to save radio resources by allowing an incoming side mobile station to determine whether or not a communicable service is included among plural services that are requested by a sending side terminal, selecting the one with high priority from among them and notifying of this to a network side. SOLUTION: A radio channel with a speed compatible with an offered service is set by preliminarily performing service negotiation in data communication. A mobile station is informed of plural selectable services at a point 'a' from a network side. The mobile station notifies two connected user terminals 1 and 2 of a service request. Each terminal 1 and 2 notifies the mobile station of the service it can offer. The mobile station calls a terminal that has an available service. A radio channel that corresponds to the service is set to the terminal that made response.
