Embodiment 5
[0073] Below in conjunction with the accompanying drawings, the embodiment of the application of the technical solution of the present invention in Multimedia Broadcast / Multicast Service (MBMS for short) will be further described in detail.
[0074] MBMS is a point-to-multipoint service that provides a data source to send data to multiple users in a mobile network, and is used to effectively realize network resource sharing (including mobile core network and access network resource sharing). MBMS is based on the existing WCDMA or GSM communication network, by adding some new functional entities such as broadcast multicast service controller (Broadcast Multicast Service Center, referred to as BM-SC), and in the existing network of packet domain functional entities such as Serving GPRS Support Node (SGSN for short), Gateway GPRS Support Node (GGSN for short), Radio Network Controller (RNC for short), and User Equipment (UE for short) Add the corresponding MBMS functional modules...
