Problems solved by technology

This multicast model cannot avoid multicast address conflicts between multicast services, so there may be multiple multicast sources using the same multicast address to send data, causing interference between multicast services; it is also impossible to limit multicast sources , so that any multicast source can send garbage data to the multicast group;
[0005] 2. Since the existing method only uses the IP multicast address and the APN to identify the multicast service, it cannot satisfy the requirement that the user only wishes to receive the multicast data sent by the specific multicast source;
[0006] 3. When GGSN joins a multicast group at the request of a user, it will receive data from all service sources in the group. I

Example Embodiment

[0037] The present invention will be described in further detail below with reference to the accompanying drawings.

[0038] In order to provide efficient broadcast / multicast service in mobile network, MBMS service is proposed in 3GPP. A reference to the network structure that can implement MBMS services figure 2 ,exist figure 2 In the shown structure, the interface between the GGSN and the multicast source is the Gi interface, and the multicast source includes the broadcast / multicast service center (MB-SC) in the figure, the multicast / broadcast source (Broadcast / Multicast Source), a multicast / broadcast source within a mobile network. In order to carry out regional characteristic services, MBMS allows the multicast services provided in the mobile network to provide services by partition, and the data distributed in different multicast service areas may be different.

Abstract

A method for managing multicast source in mobile network includes extending the MBMS context for uniquely identifying a multicast service GGSN associated with a particular source, routing for multicast data, using multicast address ID dedicated for specific source multicast for the multicast service provided by mobile network, and adding multicast group by mobile network. When user requests multicast service, particular multicast source or target service region of multicast service can be defined. Its advantage is high efficiency of GGSN multicast.

Description

technical field [0001] The invention relates to a method for managing multicast service sources in a mobile network. Background technique [0002] Providing broadcast / multicast services in the mobile network can enable data packets on the same path in the network to be transmitted once according to the service content, instead of being transmitted multiple times according to the number of subscribers, thereby saving network resources. According to the management scheme of the broadcast / multicast (MBMS) service proposed by the 3rd generation mobile communication cooperation organization (3GPP), the management method of the existing broadcast multicast service source is when the mobile user applies for the multicast service to the mobile network, the user uses The MBMS context (MBMS Context) composed of the Internet Protocol (IP) multicast address and the access point name (APN) identifies the service, and the mobile network equipment serving GPRS support node (SGSN) checks th...
