摘要： A method, a device and a system for evaluating network reliability are disclosed in the embodiments of the present invention. The method includes: determining an analysis object by acquiring network topology information; acquiring a network failure mode of the analysis object; and analyzing and evaluating reliability of the analysis object in a hierarchical and overall way with respect to the failure mode. As the concept of a hierarchical analysis is introduced into the analysis, analysis properties of analysis objects (for example, a node and a connection) are divided according to hierarchies, so that the network is effectively decomposed, an overall decomposing analysis is ensured, and the difficulty of the analysis is reduced.
摘要翻译：在本发明的实施例中公开了一种用于评估网络可靠性的方法，装置和系统。该方法包括：通过获取网络拓扑信息来确定分析对象; 获取分析对象的网络故障模式; 并且以关于故障模式的分层和整体方式分析和评估分析对象的可靠性。随着层次分析的概念被引入到分析中，分析对象（例如，节点和连接）的分析属性根据层次划分，使得网络被有效地分解，确保了整体分解分析，以及分析的难度降低。

摘要： A method for realizing an Internet protocol (IP) multimedia subsystem (IMS) disaster tolerance includes the steps as follows. An S-CSCF receives a user registration, and backs up necessary data which is required when a user service processing is restored on a storage entity in a network. An I-CSCF of user's home domain receives a service request of the user, and if it is found that the S-CSCF currently providing a service for the user fails, assigns a new S-CSCF to the user, and forwards the service request to the newly assigned S-CSCF. The newly assigned S-CSCF interrogates and acquires subscription data of the user and the necessary data backed up by the original S-CSCF from the storage entity, and then restores the user service processing according to the subscription data and the backup data. A device for realizing an IMS disaster tolerance is also provided.
摘要翻译：实现互联网协议（IP）多媒体子系统（IMS）容灾的方法包括以下步骤。 S-CSCF接收用户注册，并且备份在网络中的存储实体上恢复用户服务处理所需的必需数据。用户归属域的I-CSCF接收用户的服务请求，如果发现当前为用户提供服务的S-CSCF失败，则向用户分配新的S-CSCF，并转发该服务请求到新分配的S-CSCF。新分配的S-CSCF询问并从存储实体获取用户的订阅数据和由原始S-CSCF备份的必要数据，然后根据订阅数据和备份数据恢复用户服务处理。还提供了用于实现IMS容忍的设备。

摘要： 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.
摘要翻译：提供了一种用于IP多媒体子系统（IMS）的灾难恢复的方法，装置和系统。该方法包括：触发冗余呼叫会话控制功能（CSCF）; 通过冗余CSCF从用户的网络存储实体获得与IMPU相关联的注册的IMS私有用户身份（IMPI）的用户备份数据和IMS订阅中的IMS公共用户身份（IMPU）的用户服务配置数据; 以及根据获得的IMS订阅中的IMPU的IMPI的用户备份数据和IMPU的用户服务配置数据，由冗余CSCF恢复对应的服务。利用本发明，可以恢复一IMPU多IMPI，一IMPI多IMPU或多IMPI多IMPU服务，使用户能够获得更好的服务连续性体验。
