ABSTRACT:
A telecommunication network (TN) comprises a radio access network (2) defining cells in which user equipments (7) are localized and a core network (1) linked to the radio access network and adapted to establish a multimedia broadcast multicast context for the user equipments (7) located in the cells. It also comprises i) connecting means (16) arranged, when receiving a first request for broadcasting data to user equipments (7) localized in a broadcast area defined by at least one of the cells, to establish a first connection with the radio access network (2), and ii) requesting means (17) arranged, when the first connection is established, to send a second request to the core network (1), via the radio access network (2), in order the core network (1) establishes a second connection with the radio access network (2) for signalling with it, and, when the second connection is established, to send a third request to the core network (1), 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 (7) localized in the broadcast area.
