Abstract:
1. A method for activating a Multimedia Broadcast/Multicast Service (MBMS) in a network, the network comprising at least one Serving GPRS Support Node (SGSN) for connecting user equipments (UE) via a radio access network, at least one GGSN, and at least one BM-SC, wherein the SGSN and the GGSN are operatively connected while the GGSN and the BM-SC are operatively connected; the method comprising the steps: a1. creating, by a UE, a Packet Data Protocol (PDP) Context through interaction with the network and sending a joining message to the network via an SGSN which the UE belongs to; and a2. after receiving the joining message, implementing, by the network, an authorization to the UE, if the UE has passed the authorization, permitting the UE to activate an MBMS UE Context and the UE sending a request for activating an MBMS Context which carries MBMS bearer capabilities of the UE to the SGSN which the UE belongs to; b. verifying, by the SGSN before sending a Create MBMS Context Request, whether the MBMS bearer capabilities of the UE are less than Required MBMS Bearer Capabilities if the SGSN has the Required MBMS Bearer Capabilities, wherein the Required MBMS Bearer Capabilities are used to identify the maximum QoS ability of the MBMS service requested by the UE; and c. rejecting, by the SGSN, the request for activating an MBMS Context if the MBMS bearer capabilities of the UE are less than the Required MBMS Bearer Capabilities, or creating the MBMS UE Context if the MBMS bearer capabilities of the UE are not less than the Required MBMS Bearer Capabilities.
