一种防止呼叫会话控制功能实体活动资源挂死的方法
摘要：
本发明提供一种防止呼叫会话控制功能实体活动资源挂死的方法，会话边界控制设备故障恢复完成后，发送故障恢复消息给接入呼叫会话控制功能实体；所述接入呼叫会话控制功能实体收到故障恢复通知消息后，释放从会话边界控制接入的所有活动会话的用户资源，并通知其他呼叫会话控制功能实体释放从会话边界控制接入的所有活动会话的用户资源。本发明的方法能在会话边界控制设备故障恢复后，通知呼叫会话控制功能实体释放相应的资源，防止资源挂死。
摘要（英）：

The invention provides a method for preventing call/session control functional entity active resource from hanging. After recovery of session border controller failure is finished, a failure recoverymessage is transmitted to an access call/session control functional entity; and after receiving the failure recovery message, the access call/session control functional entity releases all the user resources of active session accessed from the session border control and notifies other call/session control functional entities to release all user resources of active session accessed from the sessionborder control. The inventive method can notify a call/session control functional entity to release correspondent resources after a session border controller failure is recovered, thereby preventingresources hanging.
