Data transmission methods of edge MBMS (Multimedia Broadcast/Multicast Service) service and related equipment

Abstract

The invention discloses data transmission methods of edge MBMS (Multimedia Broadcast / Multicast Service) service and related equipment. The methods are applied to a data transmission system of the MBMSservice. The system comprises a center BM-SC (Broadcast / Multicast Service Center) located at a core network, an edge BM-SC located at a network edge and an MBMS GW (Multimedia Broadcast / Multicast Service Gateway). One of the methods comprises: creating a control surface bearer context by the center BM-SC; sending a session starting request by the center BM-SC to the edge BM-SC to enable the edgeBM-SC to create a user surface bearer context; receiving a session starting response, which is sent by the edge BM-SC, by the center BM-SC; and issuing a service key by the center BM-SC to the edge BM-SC to enable the edge BM-SC to encrypt data of the edge MBMS service by use of the service key and send the data to UE (user equipment) through the MBMS GW. According to the methods, data transmission time delay of the edge MBMS service can be reduced, and use of core network bandwidth for data transmission of the edge MBMS service is reduced.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a data transmission method and related equipment for an edge multimedia broadcast multicast service (Multimedia Broadcast / Multicast Service, MBMS) service. Background technique [0002] The traditional mobile Internet business is based on the Over The Top (OTT) model. The business data comes from the network. The mobile network acts as a service data pipeline and is responsible for the data connection between the terminal and the network. With the development of distributed cloud computing technology, the mobile network edge has the ability to provide cloud computing services. In this context, the low-latency characteristics of edge multimedia services will bring users a new Internet experience. On the other hand, the future 5th generation mobile communication network is a network that realizes the interconnection of everything. The Internet of Vehicles and the Int...

Problems solved by technology

The detour of the forwarding plane will lead to two problems: on the one hand, the detour of the data plane will increase the service data transmission delay, which cannot meet the needs of some real-time edge multimedia broadcasting services; on the other hand, the detour of the data plane will cause the core network bandwidth Waste, when a large number of edge multimedia broadcasting services are deployed, the core network bandwidth will inevitably face greater pressure
