摘要： A method of handling a Session Initiation Protocol communication within an IP Multimedia Subsystem, where the communication is subject to a call forwarding operation handled by a Session Initiation Protocol Application Server. The method comprises receiving an INVITE at a Serving Call/State Control Function serving a user equipment identified by a R-URI of the INVITE, and at the Serving Call/State Control Function, adding a URI of the Serving Call/State Control Function to the INVITE route header together with an Original Dialog Identifier, and maintaining at the Serving Call/State Control Function a mapping between the Original Dialog Identifier and said R-URI. The INVITE is forwarded to said Application Server, and the R-URI changed to a URI of a user equipment to which the call is to be forwarded. A forwarding indicator is added to the INVITE header, and the INVITE returned to the Serving Call/State Control Function. At the Serving Call/State Control Function, the presence of said forwarding indicator is identified, and in response the original R-URI identified on the basis of the Original Dialog Identifier contained in the returned INVITE. Call restrictions and IFCs are identified on the basis of original R-URI.
摘要翻译：一种在IP多媒体子系统内处理会话发起协议通信的方法，其中通信受到由会话发起协议应用服务器处理的呼叫转移操作。该方法包括：在服务于由INVITE的R-URI标识的用户设备的服务呼叫/状态控制功能处接收INVITE，并且在服务呼叫/状态控制功能处，将服务呼叫/状态控制功能的URI添加到 INVITE路由报头和原始对话标识符，并且在服务呼叫/状态控制功能处保持原始对话标识符和所述R-URI之间的映射。 INVITE被转发到所述应用服务器，并且R-URI改变为呼叫转发到的用户设备的URI。转发指示符被添加到INVITE报头中，并且INVITE返回到服务呼叫/状态控制功能。在服务呼叫/状态控制功能中，识别所述转发指示符的存在，并且响应于基于返回的INVITE中包含的原始对话标识符识别的原始R-URI。在原始的R-URI的基础上确定呼叫限制和IFC。
