Data transmission method of edge MBMS service and correlation device

Abstract

The invention discloses a data transmission method of edge MBMS service and a correlation device. The method is applied to a data transmission system of MBMS service. The system internally comprises a center BM-SC disposed at a core network, an edge BM-SC disposed at the edge of the network, and an MBMS GW. The method comprises the following steps: the center BM-SC creating a control surface bearer context; the center BM-SC sending a session starting request to the edge BM-SC so as to enable the edge BM-SC to create a user surface bearer context; and the center BM-SC receiving a session starting response sent by the edge BM-SC; and the center BM-SC issuing a service key to the edge BM-SC so as to enable the edge BM-SC to encrypt data of the edge MBMS service by use of a service key pair and send the data to UE through the MBMS GW. According to the invention, data transmission time delay of the edge MBMS service can be reduced, and application of the bandwidth of the core network 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 (MBMS) service. Background technique [0002] Traditional mobile Internet services are based on the Over The Top (OTT) model. Service 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 Internet of Things are both important sub-network t...

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
