Abstract

A communication system supports multiple source coding and/or channel coding schemes. When a handoff is needed that transfers radiocommunication service support responsibility from a base station controlled by one MSC to a base station controlled by another MSC, signaling procedures are employed to handle the transfer as it pertains to the source coding and/or channel coding, i.e., ensuring that the new MSC links in an appropriate codec to support the handed off connection.
Various techniques are described to provide such signaling, both in the direction of the new (target) MSC and in the direction of the user equipment being handed off.
