Embodiment Construction

[0128] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention belong to the protection scope of the present invention.

[0129] Before introducing the data transmission method of the edge MBMS service provided by the present invention, first introduce the system architecture of the present invention. Because the control plane and user plane functions of MBMSGW may be implemented in the same network entity (that is, the network entity has both the control plane and user plane functions of MBMSGW), or may be implemented in different network entities (that is, the control plane functions of MBMSGW are implemented in one netwo...

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...
