Abstract

When communications between mobile terminals MSand MSare terminated, a TRAUjudges whether the communications between mobile terminals MSand MSare synchronous and notifies the mobile terminal MSof this information through both a base station control center BSCand a base station BTS. The mobile terminal MSstores this information in relation to both the dial number of the mobile terminal MSand a voice-encoding type used in communications with the mobile terminal MS. Similarly, a TRAUtransmits the same information to the mobile terminal MSand the mobile terminal MSstores this information along with the dial number of the mobile terminal MSand a voice-encoding type. When the mobile terminals MSand MScommunicate 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.
