Abstract
(EN)
A method for the synchronization of the multimedia broadcast/multicast is provided which includes the following steps: the Service Center (3) delivers the service data simultaneously with the synchronization information; the Terminal Node Controllers (2) receives the service data and delivers the service data according to the corresponding synchronization information. The method for the synchronization of the multimedia broadcast/multicast implements the sending synchronization of the service data in the Terminal Node Controllers by using the system clock and the synchronization information. When the terminal is moving in the radio network, the method ensures the seamless handover on the border of adjacent cells and the effective receiving of data for the terminal.

La présente invention concerne un procédé pour synchroniser une diffusion/multidiffusion multimédia, qui passe par les étapes suivantes : le centre de service (3) délivre les données de service simultanément avec les informations de synchronisation, les contrôleurs de nœuds de terminal (2) reçoivent les données de service et les livre selon les informations de synchronisation correspondantes. Le procédé de synchronisation de la diffusion/multidiffusion multimédia implémente la synchronisation d'envoi des données de service dans les contrôleurs de nœud de terminal à l'aide de l'horloge du système et des informations de synchronisation. Lorsque le terminal se déplace dans le réseau radio, le procédé assure le transfert fluide sur la limite de cellules adjacentes et la réception efficace des données pour le terminal.
