Filed: 1997-10-01
Abstract: PROBLEM TO BE SOLVED: To register a current CODEC type of a mobile set to a network. SOLUTION: A mobile set 11 informs an in-zone exchange 5 resident in a zone of a CODEC type supported by the mobile set 11 on the opportunity of the registration of the mobile set position or when the moving user changes a mobile set in use by using a mobile communication control signal between the mobile set and a mobile network.
