Method and broadcast multicast service server for data broadcasting in third generation networks

Abstract

A telecommunication network (TN) comprises a radio access network () defining cells in which user equipments () are localized and a core network () linked to the radio access network and adapted to establish a multimedia broadcast multicast context for the user equipments () located in the cells. It also comprises i) connecting means () arranged, when receiving a first request for broadcasting data to user equipments () localized in a broadcast area defined by at least one of the cells, to establish a first connection with the radio access network (), and ii) requesting means () arranged, when the first connection is established, to send a second request to the core network (), via the radio access network (), in order the core network () establishes a second connection with the radio access network () for signalling with it, and, when the second connection is established, to send a third request to the core network (), via the first and second connections, for establishment of a MBMS context, in order to activate a broadcast service for broadcasting the data to the user equipments () localized in the broadcast area.
