摘要

对OMA(open mobile alliance)提出的基于IMS(IP multimedia subsystem)平台的PoC(push to talk over cellular)服务器处的RTP(real-time transport protocol)媒体流转发机制进行了分析建模并进行了改进。新机制通过引入分布式控制的思想来增强参与服务器侧控制功能

将RTP流的转发操作提前到参与服务器处完成

达到了减轻控制服务器处瓶颈效应、平衡网络流量负载和优化数据传输时延的目的。分析和仿真结果表明新机制在平衡网络负载和优化数据传输时延方面较旧机制有明显的改进。

Abstract

After modeling the RTP（real-time transport protocol） stream transferring scheme proposed by OMA（open mobile alliance） for PoC（push to talk over cellular） server

an improved scheme was presented.Under the new scheme media traffic through CS（controlling server） could be reduced largely and the transferring delay of RTP package could also be shortened obviously by enhancing PS（participating server） controlling capabilities and importing distrib-uted-controlling ideas into PoC system.Analyzing and simulation results show that the new scheme always performs bet-ter than the original one in fields of load balancing and media transferring delay optimization.
