摘要: 针对某些网络对业务和用户划分优先级的问题,该文基于现有会话初始化协议(SIP)栈设计一种支持服务质量(QoS)的PQ_SIP协议栈,并将其应用于某部人民防空应急通信指挥系统中。实践证明,改进后的协议栈能有效提高终端资源的利用率,体现用户和数据业务的不同优先级,实现对呼叫和会话有差别的控制。

Abstract: Session Initiation Protocol(SIP) can implement the control of Next Generation Network(NGN) integration service, but it can not make a difference between users and data services. In order to solve these problems, this paper presents a new Priority Qos Session Initiation Protocol (PQ_SIP) based on the SIP protocol, proves that the PQ_SIP protocol stack can reduce the resource consume of terminal, distinguish the priority of users and service, and implement the separation of call control and session control.

Key words: Next Generation Network(NGN), Session Initiation Protocol(SIP), priority, request message, header
