摘要
电信网络逐步向IP网络演进,基于IP网络的SIP(会话初始协议)逐步成为视频、音频多媒体业务互通的主要会话控制协议。呼叫控制为了满足多种网络融合互通的需要,提出以SIP协议互联互通,兼容传统信令的设计思想。呼叫控制实体通过实时同步用户号码实现呼叫寻址。基于IP网络呼叫控制实体会话逻辑处理上只有源和目的节点,没有中间节点,简化了呼叫寻址的处理逻辑。基于IP技术设计的呼叫控制为实现媒体设备动态组网提供了设计参考。
With the gradual evolution of teleeom network to IP network,SIP based on IP network has become the main session control protocol of video and audio multimedia service. In order to meet the needs of integration and interoperability of a variety of networks,a design of call control using SIP protocol for interoperability is proposed, which is compatible with the traditional signaling. The call control entity achieves call addressing through real-time synchronous user number.The IP network call control session handles only the source and destination node and there is no intermediate node ,which simplifies the processing logic of call addressing.The call control based on IP network offers a design reference to the implementation of dynamic media device network.
