Abstract

The invention discloses a method to realize video service in wireless communication system, which is suitable to a plurality of video services with service stream transmission. The invention is characterizes in comprising: acquiring video service parameters, the acquired video service parameters comprise service quality QOS parameters of all service streams and synchronous indication parameters of synchronous frames in all service streams; distributing the resource of the service streams according to the QOS parameters, and transmitting the synchronous frames of the service streams synchronously according to synchronous indication parameters and the distributed resource. The invention has the advantages of improving the video service quality by adopting the technical proposal provided by the invention.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and network element equipment for realizing video services in a wireless communication system. Background technique [0002] In a packet-switched mobile communication system, it has become a typical application in the system to carry various video services through IP connections. Video services include multiple data streams, for example, video streams, audio streams, and subtitle streams. Wherein, the video stream includes: an I frame carrying scene key information and a P frame carrying scene auxiliary information. In a packet-switched mobile communication system, there are usually two ways to carry video services. One way is to transmit the entire video service through one connection, that is, the video stream, audio stream and subtitle stream in the video service are all in one Transmission in service streams, for example, IPTV and Mobile TV services usually ...
