摘要：

目前国内外各通信标准组织都将以3GPP IMS为基础的网络作为未来语音交换网络的演进方向，由于未来的IMS网络将在很长一段时间内与基于电路交换的电话网络共存，因此存在着IMS中SIP用户呼叫E.164号码被叫用户时的路由选择判断问题。为此，本文给出了3GPP IMS中SIP用户呼叫E.164号码被叫用户时在主叫归属S-CSCF可采取的三种路由方案：S-CSCF自身路由方案、ENUM查询判断方案以及BGCF路由判断方案，并对这三种方案进行了分析比较与应用建议。

Abstract:

At present, the international communication standard organizations take the network based on IMS as the evolution target of the future voice switch network, because the future IMS will coexists with the network based on CS for a long time, the problem of route selection and decision occurs when SIP user calls E.164 user in IMS. Therefore, this paper gives 3 route solutions when SIP user calls E.164 user in IMS: S-CSCF self routing solution, ENUM querying decision solution, and the BGCF routing selection solution, and gives the compare analyze and application suggestion at the same time.

Key words: IMS, SIP, E.164, routing
