"Method to select and establish a service option from multiple options of service in a digital mobile communication system, a communication network 1 which has accommodated in mobile CDMAA plurality of base stations for Radio 4 and a device register location 5.A mobile terminal 6 makes telephone conversation and communication with another mobile terminal 6 through the respective areas of base stations of wireless radio related 4.A switching station 3 has a record of the location of the visitor 3A which has data of the subscriber by mobile terminal 6.The switching station 3 selects a service option OS from a plurality of compression rates of voice.The service option OS which is to be applied beforehand with the higher priority.The switching station 3 obtains the service option from the appliance location register 5, and the station switching system provides this service option data to the subscriber.By means of this service option OS, the switching station 3 performs its first call connection with the mobile terminal 6.At the time of connection of the call,The switching station 3 confirms the choice of service so that the mobile terminal 6 supports through a negotiation of service with the mobile terminal 6 and a switching station 3 stores the option DAnd service only. The station switching system 3 refers to the service option are thus stored with respect to the mobile terminal 6 when carrying out their subsequ00b3entes call connections.By consequ00b3u00eancia, it is possible to eliminate the need to carry out a negotiation of service option connection each time a call is made.In this way, it is possible to reduce the length of time required to perform a call connection. In this way, it is possible to eliminate the processing load on the network switching system.
