摘要：
The present invention provides a method for obtaining a proxy call session control function address, comprising when a terminal accesses an IP multi-media subsystem through a world interoperability for microwave access (WiMAX) network in roaming scenarios, a visited authentication, authorization, and accounting server (V-AAA) of the terminal retransmitting an access request message sent by an access service network (ASN) or a dynamic host configuration protocol (DHCP) or a home agent (HA) of said terminal to a home authentication, authorization, and accounting server (H-AAA) of said terminal after receiving the access request message, and H-AAA finally deciding whether the P-CSCF is located in a visited network or a home network according to a roaming protocol and visited network capability, and returning the determined P-CSCF address information, included by H-AAA in an access accept message corresponding to said access request message, to the sender of said access request message through V-AAA.
摘要（中）：
本发明提供了一种用于获取代理呼叫会话控制功能地址的方法，包括当终端通过漫游场景中的微波接入（WiMAX）网络的世界互操作性访问IP多媒体子系统时，访问认证，授权和计费 服务器（V-AAA）将由所述终端的接入服务网络（ASN）或动态主机配置协议（DHCP）或本地代理（HA）发送的接入请求消息重传到家庭认证，授权和 计费服务器（H-AAA），H-AAA根据漫游协议和访问网络能力最终确定P-CSCF是否位于访问网络或家庭网络中，并返回 将由所述接入请求消息对应的接入接收消息中的H-AAA所包含的确定的P-CSCF地址信息发送给所述接入请求消息的发送者 哦V-AAA。
