ABSTRACT:
Procedures are provided for the establishment of MBMS services in different cells of a cellular telecommunications network, in particular, for maintaining the transmission of MBMS data to a particular user equipment, even when it moves from one cell to another when the service is provided in different ways in different cells. In particular, when a user equipment receives a multimedia data service in a first cell via a certain type of connection (i.e., a point-to-point connection/while requiring an RRC Connection, a point-to-multipoint connection without/while requiring an RRC Connection), and moves to a second cell where the type of connection used to provide the service is different, specific actions are undertaken (e.g., request for an RRC Connection, release of an RRC Connection, etc.), depending on the type of connection change carried out. Embodiments for the establishment of the most adequate connection (p-t-p, p-t-m) in a cell are disclosed as well (e.g., by sending a message from a SRNC to a CRNC).
