Abstract: Efficient processing and/or routing of emergency calls in an IMS (IP Multimedia Subsystem) for VoIP (Voice over IP) subscribers can be enabled. In one aspect, an E911 profile is generated, for example, by an application server, for each VoIP subscriber based in part on current location information associated with the subscriber, such as, the subscriber's IP address. The E911 profile is pushed to the HSS (Home Subscriber Server) of the IMS. The E911 profile can then be stored in the HSS and can be queried by an E-CSCF (Emergency Call Session Control Function) during emergency call processing. Moreover, when an emergency call is received from the subscriber, the E-CSCF can retrieve the E911 profile associated with the subscriber from the HSS and route the call to an appropriate PSAP (Public Safety Answering Point) based on an analysis of the information in the E911 profile.

Abstract translation: 可以启用用于VoIP（IP语音）用户的IMS（IP多媒体子系统）中的紧急呼叫的有效处理和/或路由。 在一个方面，部分地基于与用户相关联的当前位置信息，例如用户的IP地址，例如由应用服务器为每个VoIP用户生成E911简档。 E911配置文件被推送到IMS的HSS（归属订户服务器）。 然后可以将E911配置文件存储在HSS中，并在紧急呼叫处理期间通过E-CSCF（紧急呼叫会话控制功能）进行查询。 此外，当从用户接收到紧急呼叫时，E-CSCF可以从HSS检索与订户相关联的E911简档，并且基于对该信息的分析将呼叫路由到适当的PSAP（公共安全应答点） E911配置文件。

Abstract: Many of the current IMS standards and enriched services were originally designed for the individual subscribers that are serviced by the wireless network. However, the IMS standards do not fully address the problem of providing the IMS enriched services and features to business PBX customers or wholesale customers that do not directly register to the IMS network. The present invention discloses a method for providing IMS enriched services and features to business PBX customers or wholesale customers through the use of a static provisioning and registration method.

Abstract: A method for providing multimedia services to subscriber user equipment (UE) within an IP multimedia subsystem network (IMS) may include configuring the IMS to enable a single UE to fork register and cooperate with multiple serving-call session control functions (S-CSCFs). After obtaining IP connectivity, the single UE signals to register with the IMS and the IMS determines whether the UE is configured to fork register with multiple S-CSCFs. If the UE is configured, the IMS determines which S-CSCFs are eligible for the UE registration and fork registers the UE to multiple S-CSCFs of the eligible S-CSCFs. Consequently, incoming and outgoing calls to/from the UE are routed by the IMS to any of the multiple registered S-CSCFs.
