Abstract

The invention discloses a method and system for ensuring streaming media service quality. The method comprises the steps of monitoring the performance of a current network and triggering switch when monitoring that the performance of the current network is insufficient to meet the demands on the service quality of steaming media service; determining a target network, notifying a mobile node aboutthe relevant information for switching the target network, and sending service quality parameter information of the steaming media service of the mobile node to a target service quality proxy functionmodule in a target network node from an original service quality proxy function module in the original access network node; using the target service quality proxy function module in the target network node for establishing service quality mapping; and adopting different switch strategies according to different types of the mobile nodes: adopting a synchronous algorithm for carrying out data transmission when the mobile node is dual interfaces and adopting the switch strategy based on cache when the mobile node is a single interface. The method and the system can avoid the problem of low datatransmission efficiency due to the use of dual network interface cards in the prior art, lead a plurality of access modes to work cooperatively and realize seamless switch.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and system for ensuring the service quality of streaming media in a heterogeneous network based on smooth switching. Background technique [0002] The rapid development of mobile communication technology has greatly enriched various applications. In addition to traditional services such as high-speed Internet access and file downloads, streaming media services such as IPTV (Interactive Internet Television) and video telephony have greatly expanded the concept of communication services. And become the most attractive business of the new generation mobile communication system. Therefore, in the next-generation heterogeneous converged network, when the mobile node is within the coverage of multiple networks, provide users with the best connection mode and configuration mode. When there are more access users, how to still It is of great research significance to ensur...
