Abstract

The invention relates to a method for seamless switch of mobile flow media transmission in the wireless mobile network, which uses multiple-path adaptive transmission speed regulation to realize the seamless switch of transmission layer, as dynamically regulating the layered multiple description video code strategy of flow media, according to the property of each path of multiple-path wireless access parallel transmission, to distribute the multiply-path transmission video code flow, and utilize the available band width of receiver most, to realize the stable transmission and smooth switch of transmission layer of mobile flow media. The invention can improve the band width, the transmission reliability, and reduce the network switch delay and the loss rate, to avoid the vibration which will affect the video quality of flow media. The invention can fully utilize present wireless network resource, with simple operation.

Description

technical field [0001] The present invention relates to a seamless switching method for mobile streaming media transmission in a wireless mobile network, to be precise, relates to an effective combination of multi-path wireless access concurrent transmission and video streaming media layered multi-description coding, The method for realizing the smooth handover of the mobile streaming media at the transport layer can be called Matra-TraSH (Multi-PathAdaptive Transmission Rate Adjustment for Transport layer Seamless Handover), which adopts the adjustment of multi-path adaptive transmission rate to realize the seamless handover of the transport layer. In the switching process of the wireless mobile network, the invention can effectively guarantee the streaming media reception quality of the mobile terminal, and provides an effective way for the integration of the next generation heterogeneous wireless access network, and belongs to the technical field of mobile communication.
