Broadcast mbms transmission system and method, core network and access network

Abstract

The present invention provides an MBMS transmission system and method suitable for broadcasting services, core network equipment and access network equipment, characterized in that the core network includes: a service control platform for service control functions related to broadcast service data; and the integrated broadcast service entity, which are used for session management and transmission configuration functions of broadcast service data, wherein the service control platform is connected between the content source and the integrated broadcast service entity, and the integrated broadcast service entity communicates with the broadcast service entity through a one-way interface and a static configuration channel respectively RAN communication connection, adaptability and simplification Redesign the overall transmission architecture and core network elements, as well as the transmission mode between the control plane and the user plane, according to the actual situation of the current regional deployment network, combined with the characteristics of the one-way transmission network , to simplify some network elements and interface functions to meet the characteristics of one-way transmission.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to an MBMS transmission system and method for transmitting broadcast services, related core network equipment and access network equipment. Background technique [0002] With the rapid development of the Internet, people's requirements for Internet transmission are gradually increasing, especially the continuous boom in audio and video services, which increases the transmission pressure on the current network transmission. In the future, 4K / 8K ultra-high-definition video, 3D stereoscopic video, multi- View video, VR (virtual reality) / AR (augmented reality) and other high-quality multimedia services will greatly promote the expansion of broadcast TV to mobile terminals in the future and bring prosperity to the high-definition video market. [0003] If all services are considered for individual users and distributed in unicast mode, it will bring huge pressure on the bandwidth ...

AI Technical Summary

Problems solved by technology

[0007] There is such a technical problem in the existing technology: the overall architecture, core network, and related equipment of the existing 5G MBMS are two-way network characteristics, but the objective condition for deployment is that the distance between the core network of the 5G broadcast service and the broadcast tower The transmission interface of the 5G broadcast service is a one-way interface, so the broadcast service cannot directly copy the existing 5G MBMS architecture for transmission. In other words, the overall architecture, core network, and related equipment of the 5G broadcast service MBMS require a one-way transmission network Features are given targeted consideration and overall redesign
