Abstract
A mobile station (115) and its supporting infrastructure equipment negotiate service configurations based on the service option capabilities of both the mobile station (115) and the infrastructure equipment. This negotiation process is performed via a traffic channel which is primarily intended for carrying vocoded voice information. The infrastructure equipment manages the capabilities of the transcoder circuits and checks the transcoder availability before proposing or accepting a particular service configuration. When a mutual service configuration is reached, the infrastructure equipment reallocates a new transcoder circuit based on its service option capability and the precheck of the transcoder availability and informs the mobile station (115) when to reset its layer 2 (L2) sequence number via an ACTION.sub.-- TIME parameter. After switching transcoders, the infrastructure equipment and the mobile station (115) reset their respective sequence numbers at the ACTION.sub.-- TIME to complete L2 synchronization during transcoder switching.
