  • Communications system
    Publication number: 20070049306
    Abstract: When communications between mobile terminals MS1 and MS2 are terminated, a TRAU1 judges whether the communications between mobile terminals MS1 and MS2 are synchronous and notifies the mobile terminal MS1 of this information through both a base station control center BSC1 and a base station BTS. The mobile terminal MS1 stores this information in relation to both the dial number of the mobile terminal MS2 and a voice-encoding type used in communications with the mobile terminal MS2. Similarly, a TRAU2 transmits the same information to the mobile terminal MS2 and the mobile terminal MS2 stores this information along with the dial number of the mobile terminal MS1 and a voice-encoding type. When the mobile terminals MS1 and MS2 communicate the second time, communications are conducted using another voice-encoding type if the communications are asynchronous and using the previous voice-encoding type if the communications are synchronous, based on the information stored in this way.
