Abstract

The invention relates to a selection method of a server of mobile IPTV (Internet Protocol Television), a client, a server and a system. The method comprises the following steps of: sending an IPTV service request; receiving a media server list sent by a proxy server according to the IPTV service request, wherein the media server list includes a default media server; establishing the connection of the media server list and the default media server according to the media server list; sending a server quality probe data packet to each media server in the media server list; receiving a probe data packet returned by each media server, calculating and comparing the service quality parameter of each media server, and selecting the media server according to a selection strategy of the media server. According to the technical scheme provided by the invention, an optimal media server can be rapidly found and switched to meet the QoS requirement when a position of a mobile terminal is changed so as to avoid the degradation of the service quality.

Description

technical field [0001] The present invention relates to mobile communication technology, and specifically relates to a server selection method, client, server and system of a mobile network television IPTV. Background technique [0002] In the IPTV network, in order to reduce the network access and signaling interaction delay, solve the contradiction between the limited bandwidth resources of the backbone network and the high bandwidth demand caused by the large number of concurrent users, and improve the quality of user experience (QoE), the IPTV service platform uses CDN The network (Content Delivery Network: Content Delivery Network) completes the distribution, transmission and storage of video and audio content. The IPTV CDN network consists of a series of media servers, and the media content is stored on each media server in a distributed manner. Therefore, when a terminal requests an IPTV service, it is necessary to select an optimal server on the CDN network for the ...
