Abstract
Based on the technical background of media streaming over GPRS (General Packet Radio Service) mobile network, a novel media streaming cache architecture of two-level proxy is proposed for streaming service in GPRS network. CCP (Central Cache Proxy) and UECP (User-End Cache Proxy) are applied to improve the performance of streaming service and to decrease the load of GPRS core network. Key technical details correlated to this architecture are researched, such as: reliability design of proxy server, caching policy, and strategy of charging and billing. Analyses and simulation experiments prove that this two-level caching proxy architecture can effectively optimize the performance of streaming service in GRPS network without upgrading the original GPRS network entities.
