摘要： Embodiments of the present invention disclose a method for routing control applied to a communication system including a CS domain and an IMS and in which a Routing Policy Decision-making Point (RPDP) is set; and the method includes: initiating a routing query to the RPDP by an interrogation network unit in the communication system upon receiving a service request; making a routing decision by the RPDP according to routing decision-making related information and the routing policy information, returning the routing decision to the interrogation networking unit by the RPDP; and performing subsequent routing control by the interrogation network unit according to the routing decision. Embodiments of the present invention also disclose a system for routing control. In accordance with the embodiments of the present invention, across-domain routing control is thus realized in different network application environments according to different demands.
摘要翻译：本发明的实施例公开了一种应用于包括CS域和IMS的通信系统的路由控制方法，其中设置了路由策略决策点（RPDP）并且所述方法包括：在接收到服务请求时，通过所述通信系统中的询问网单元向所述RPDP发起路由查询; 根据路由决策相关信息和路由策略信息，由RPDP进行路由决策，RPDP将路由决定返回给询问组网; 以及根据路由决定执行询问网络单元的后续路由控制。本发明的实施例还公开了一种用于路由控制的系统。根据本发明的实施例，根据不同的需求，可以在不同的网络应用环境中实现跨域路由控制。

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。
