摘　　要：A mobile transmission strategy, PMPatching (Proxy-based Mobile Patching) transmission strat-egy is proposed, it applies to the proxy-based mobile streaming media system in Wideband Code Division Multiple Access (WCDMA) network. Performance of the whole system can be improved by using patching stream to transmit anterior part of the suffix that had been played back, and by batching all the demands for the suffix arrived in prefix period and patching stream transmission threshold period. Experimental results show that this strategy can efficiently reduce average network transmission cost and number of channels consumed in central streaming media server.A mobile transmission strategy, PMPatching （Proxy-based Mobile Patching） transmission strategy is proposed, it applies to the proxy-based mobile streaming media system in Wideband Code Division Multiple Access （WCDMA） network.
