Method for broadcasting multimedia data by controlled synchronization of the broadcasting times of the base stations of an FDMA/TDMA network and use of a common carrier frequency

摘要

A method is dedicated to broadcasting multimedia data in multimedia sessions set up in an FDMA/TDMA type communication network comprising cells (C1-C3) associated with base stations (BTS1-BTS3) adapted to broadcast the multimedia data to mobile communication terminals (MS). This method consists in, on the one hand, controlled synchronization, relative to a reference clock, of the times of broadcasting identica! multimedia data relating to the same multimedia session in each base station that the multimedia session concerns and, on the other hand, configuration of each of the base stations concerned so that they broadcast the identical multimedia data of the multimedia session during chosen periods by means of at least one chosen common carrier frequency and in at least one common chosen time slot.
