Ev-Do多流业务T2P算法研究与应用

Research on T2P Algorithm and Its Application on Multiflow Service in Ev-Do System

随着天翼对讲(Qchat)、警务通(实时视频)等行业应用的规模发展,在网络资源拥塞的情况下,保障用户业务感知日益重要。T2P算法是Ev-Do RevA系统中,控制不同用户、不同业务反向速率的关键技术。本文通过深入研究T2P相关函数、参数,分析比较主流设备T2P的参数设置,创新地提出了一套T2P反向流控参数模板,保证Qchat和警务通两种典型的反向时延敏感和速率敏感业务的感知,并且在现网推广应用。本文提供的方法对于提升Ev-Do多流业务性能具有一定的指导意义。

As the scale development of Qchat, real-time video service, improving the service experience is important in the case of network congestion. The T2P algorithm is the key technology, which controls reverse rates of different subscribers, services in the Ev-Do RevA system. The T2P transaction function was studied and the T2P parameter settings in major device system was analyzed. A new T2P reverse flow control parameters scheme to ensure the performance of Qchat and real-time video, which are the typical reverse delay-sensitive and rate-sensitive service, was also creatively proposed. Furthermore, the scheme was applied in the operation network. The scheme has important practical value to enhance the performance of the multiflow service in Ev-Do system.
