Abstract: A method, apparatus, and system for disaster recovery of an IP Multimedia Subsystem (IMS) are provided. The method includes: triggering a redundant Call Session Control Function (CSCF); obtaining, by the redundant CSCF, user backup data of registered IMS Private User Identities (IMPIs) that are associated with IMPUs and user service configuration data of IMS Public User Identities (IMPUs) in an IMS subscription from a network storage entity of a user; and recovering, by the redundant CSCF, a corresponding service according to the obtained user backup data of the registered IMPIs and user service configuration data of the IMPUs in the IMS subscription. With the present invention, the one-IMPU multi-IMPI, one-IMPI multi-IMPU, or multi-IMPI multi-IMPU service can be recovered, and this enables the user to have better service continuity experiences.

Abstract: A Serving Call Session Control Function (S-CSCF) receives a registration request message carrying an IMS Private User Identity (IMPI) and IMS Public User Identity (IMPU) pair. The S-CSCF determines: a lack of registration data corresponding to the IMPI and IMPU pair; and that the registration request message includes a reg-id parameter indicating that the registration request message relates to a multi-registration. The S-CSCF sends a Server Assignment Request (SAR) message to a Home Subscriber Server (HSS). The SAR message carries the IMPI and IMPU pair, a parameter for identifying that the SAR message relates to an initial registration of a user, and a multiple registration indication which indicates that the SAR message relates to a multi-registration associated with the IMPI and IMPU pair. The S-CSCF receives a Server Assignment Answer (SAA) message carrying registration backup data corresponding to the IMPI and IMPU pair from the HSS.

Abstract translation: 服务呼叫会话控制功能（S-CSCF）接收携带IMS私有用户身份（IMPI）和IMS公共用户身份（IMPU）对的注册请求消息。 S-CSCF确定：缺少对应于IMPI和IMPU对的注册数据; 并且注册请求消息包括指示注册请求消息涉及多注册的注册参数。 S-CSCF向归属订户服务器（HSS）发送服务器分配请求（SAR）消息。 SAR消息携带IMPI和IMPU对，用于识别SAR消息与用户的初始注册相关的参数，以及指示SAR消息与与IMPI和IMPU相关联的多注册的多个注册指示 对。 S-CSCF从HSS接收携带对应于IMPI和IMPU对的注册备份数据的服务器分配应答（SAA）消息。
