Implementing method, system and apparatus for multimedia broadcast/multicast service

Abstract

The invention discloses a method for realizing multimedia broadcasting / multicast service, which comprises that: in the dialog-start flow, the carrying between the user equipment in the accessing network and BM-SC in the core network is established, and the local IP multicast relation between the interface network element of the core network and the interface network element of the accessing network; in the process of data transmission, according to the local IP multicast relation established in the dialog-start flow, by means of IP multicast, the interface network element of the core network sends the multi-media broadcasting / multicast data package received from BM-SC to various interface network elements of the accessing networks which join in the local IP multicast, and the interface network element of the accessing network sends the multi-media broadcasting / multicast data package to the corresponding user equipment. The invention further discloses a system for realizing the multi-media broadcasting / multicast service and a device thereof. The GTP head is modified so as to facilitate the GTP head to be carried by the IP multicast, the resource utilization efficiency between the core network and the accessing network can be improved, and the burden of the transmission network is lowered.

Description

technical field

[0001] The present invention relates to the field of mobile communication, in particular to a method, system and device for realizing a Multimedia Broadcast / Multicast Service (MBMS) service. Background technique

[0002] Multicast and broadcast are technologies for transmitting data packets from one data source to multiple destinations. With the rapid development of the Internet, a large number of multimedia services emerge, some of which require multiple users to receive the same data at the same time, such as video on demand, TV broadcast, video conferencing, online education or interactive games. In order to effectively utilize mobile network resources, the Third Generation Partnership Projects (ThirdGeneration Partnership Projects, 3GPP) proposed a multimedia broadcast / multicast service, that is, a point-to-multipoint point-to-multipoint service that provides a data source in a mobile network to send data to multiple users business, realize network resou...
