Abstract
To register current codec types of a mobile station with a network side, the mobile station notifies, when it conducts the location registration or a mobile user replaces his or her old mobile station, a visitor location switching system which is associated with the current location of the mobile station, of the codec types supported by the mobile station using a mobile communication control signal between the mobile station and the mobile network. Receiving the notification, the visitor location switching system enters the update of the codec types into a location register in a memory home station that controls the mobile network The codec types can be thus registered into the mobile network using the mobile communication control signal. Since the mobile network can always acquire the latest codec types for the mobile station, the discrepancy is canceled between the codecs the mobile station supports and the codecs the network registers.
