删除Diameter路由代理中绑定的方法、系统及策略服务器
摘要：
本发明提供了一种删除Diameter路由代理中绑定信息的方法，包括：在第一策略服务器和第二策略服务器为用户设备建立的策略控制会话终结时，所述第一策略服务器判断所述第二策略服务器所在域是否存在Diameter路由代理DRA，如果存在，则向所述第二策略服务器所在域发送消息，请求删除所述DRA中所述用户设备的DRA绑定。本发明还提供一种策略服务器。提供了一种删除Diameter路由代理中绑定信息的系统。本发明在策略控制控制终结时，先判断是否存在DRA，在存在DRA时，才发送消息删除DRA绑定，避免了不必要的信令发送。
摘要（英）：

The invention provides a method for deleting bound information in a DRA (Diameter routing agent). The method comprises that when a strategy control session established by a first strategy server and a second strategy server for user equipment is terminated, the first strategy server determines whether a domain where the second strategy server is located exist any DRA (Diameter routing agent), and if any DRA exists, the first strategy server sends a message to the domain where the second strategy server is located to make a request of deleting DRA bindings in the user equipment. The invention further provides a strategy server. A system for deleting bound information in a DRA (Diameter routing agent) is further provided. According to the method, the system and the strategy server, when the strategy control session is terminated, whether a DRA exists or not is firstly determined, and only when a DRA exists, a message then is transmitted to delete the DRA bindings, and thus unnecessary signaling sending is prevented.
