Method and broadcast multicast service server for data broadcasting in third generation networks
First Claim
1. A method of transmitting data between network equipments in a telecommunication network comprising a radio access network (2) defining cells in which user equipments (7) are localized and a core network (1) linked to said radio access network and adapted to establish a multimedia broadcast multicast context, named “
- MBMS context”
, for said user equipments (7) located in said cells, characterized in that it comprises the steps of;
transmitting a first request for broadcasting data to user equipments (7) localized in a broadcast area defined by at least one of said cells, to a broadcast multicast service server (9) of said telecommunication network, establishing a first connection between said broadcast multicast service server (9) and said radio access network (2), sending a second request from said broadcast multicast service server (9) to said core network (1), via said radio access network (2), to establish a second connection between said radio access network (2) and said core network (1) for signalling in between, sending a third request, from said broadcast multicast service server (9) to said core network (1), via said first and second connections, for establishment of a MBMS context, in order to activate a broadcast service for broadcasting said data to said user equipments (7) localized in said broadcast area.

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.
