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.
