摘要
IMS是3G系统中核心网的重要部分,由SIP提供的会话发起能力建立起端到端的会话,并获得所需要的服务质量。本文基于有限状态机提出了一种新的面向IMS网络的SIP信令协议栈。通过在软终端上的功能、性能和可靠性测试,本文提出的SIP协议栈能够有效地完成多媒体通信功能。
IMS (IP multimedia subsystem) is an important part of 3G system core network, and it uses SIP protocol to initiate session for end-to-end connection establishment, and then gains service quality requirement. This paper proposes a new SIP protocol stack for IMS network. The performance and reliability testing based on the soft-terminal shows that the proposed SIP protocol stack can effectively perform multimedia communication.
