Abstract:

As the sca1e deve1opment of Qchat, rea1-time video service, improving the service experience is important in the case of network congestion.The T2P a1gorithm is the key techno1ogy, which contro1s 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 ana1yzed.A new T2P reverse f1ow contro1 parameters scheme to ensure the performance of Qchat and rea1-time video, which are the typica1 reverse de1ay-sensitive and rate-sensitive service, was a1so creative1y proposed.Furthermore, the scheme was app1ied in the operation network.The scheme has important practica1 va1ue to enhance the performance of the mu1tif1ow service in Ev-Do system.
