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.
La présente invention concerne un système de communication qui prend en charge des programmes multiples de codage de source et/ou de codage de canal. Lorsqu'un transfert est nécessaire, ce qui consiste à transférer la responsabilité de la prise en charge de service de radiocommunication d'une station de base commandée par un centre de commutation mobile (MSC) à une station de base commandée par un autre MSC, on utilise des procédures de signalement pour effectuer ce transfert, par exemple parce qu'il concerne le codage de canal et/ou le codage de source, en faisant en sorte que ce nouveau MSC se raccorde à un codec approprié de façon à prendre en charge ce transfert de connexion. Cette invention concerne aussi diverses techniques permettant d'obtenir ce signalement, en direction du nouveau MSC (cible) et en direction de l'installation utilisateur objet de ce transfert.
