A method and system for a handoff in a broadcast communication system is disclosed. A subscriber-assisted handoff is impractical in a broadcast communication system due to e.g., a high signaling load, a difficulty to synchronize the broadcast transmission. On the other hand, the small number of broadcast channels enables the subscriber station to perform the handoff autonomously. While performing a handoff between broadcast transmissions, a disruption of service occurs due to lack of synchronization among the broadcast transmissions. To reduce the service disruption, upon detecting a need for handoff, the lower layers inform the application layer about the forthcoming handoff. The application layer thus may take measures to reduce or prevent the disruption.

L'invention concerne un procédé et un système de transfert intercellulaire avec coupure dans un système de communication de diffusion. D'une part, un transfert assisté par un abonné n'est pas pratique dans un système de communication de diffusion en raison, par exemple, d'une charge de signalisation élevée, ou d'une difficulté à synchroniser la transmission de diffusion. D'autre part, le faible nombre de canaux de diffusion permet à la station de l'abonné d'effectuer le transfert de manière autonome. Pendant qu'un transfert est effectué entre des transmissions de diffusion, un manque de synchronisation entre les transmissions de diffusion entraîne une panne de service. Après détection d'un besoin de transfert, les couches inférieures informent la couche application d'un transfert à venir, de manière à réduire les pannes de services. Ladite couche application peut ensuite prendre des mesures afin de réduire ou d'empêcher les pannes.
