摘要
移动IP技术对于移动性的支持在网络层,需要对网络协议进行修改,而SIP协议在应用层提供了对移动性的支持,无需底层网络协议的改变。文中深入探讨了SIP协议在应用层支持个人移动性的工作原理,设计了两个典型的个人移动性应用场景,进行了试验验证并对试验结果进行了分析讨论。试验充分证明了SIP协议在应用层对于个人移动性的良好支持,为解决底层移动协议对移动性支持所带来的种种问题以及移动IP缺失的环境提供了有益的补充。
Mobile IP technology for support for mobility in the network layer,network protocols need to be modified,while the SIP protocol at the application layer provides support for mobility without changing the underlying network protocol.This in-depth study of the SIP protocol at the application layer mobility support individuals working principle,design of two typical individual mobility scenarios were tested and the test results are analyzed and discussed.Test fully proved SIP protocol at the application layer mobility for individuals with good support,to address the underlying mobility protocols for mobility support for the various problems arising from missing as well as mobile IP environment provides a useful supplement.
