摘要： A load balancing method is provided: A load balancer obtains an invalidation notification, where the invalidation notification includes an identifier of an invalid object on a target side, and the invalid object includes an invalid interaction node, an invalid session group on an interaction node, or an invalid session in a session group; the load balancer broadcasts the invalidation notification, where the invalidation notification is used to instruct an interaction node on a source side to delete recorded information about a load balancing protocol of the invalid object; and the load balancer reassigns an interaction node to an application interaction request when the load balancer receives the application interaction request sent by the interaction node on the source side and destination data in the application interaction request is empty. In this way, reliability of message exchanging is ensured when an interaction node is abnormal.

摘要： A method and a system for exercising policy control, a policy and charging enforcement function (PCEF) are provided, which can solve the problem that no policy control can be exercised over application service flows without an application function (AF). In the method, a PCRF receives information about an application event sent by a PCEF after subscribing the application event from the PCEF; and the PCRF generates a control policy for a service flow of the application according to the information about the application event. In the present invention, the PCEF sends the obtained information about the application event to the PCRF, so that even when no AF is involved, the PCRF can still generate a control policy according to policy contexts including the information about the application event and the like.
