摘要： 研究了SIP在无线网络中的应用,探讨了由于其信令过于冗长,存在瓶颈现象的通常解决方案,采用SigComp技术对SIP信令进行压缩.在此基础上,提出了一种智能档案(smart profile)的机制.对于SIP会话过程中的固定消息部分,采用档案存储而减少传输消息的大小.试验测试和理论分析表明,该机制在精简SIP消息大小、节省信道资源的同时,也降低了SIP信令在无线网络中的传输延迟.

Abstract: 3GPP has decided that SIP should be chosen as a control protocol of its core network. But SIP messages are usually too lengthy even become a bottleneck of its application in wireless network. SigComp technology is thus presented as a usual solution to the problem, and a new scheme called smart profile is proposed. Both test results and theoretical analysis indicate that the new scheme will not only minimize the size of SIP messages to be transmitted and save the channel resources, but also reduce the delay of transmitting SIP signal in wireless network.
