Abstract:
1. A method of realizing event detection, comprising: receiving, by a network device configured as a policy and charging enforcement function (PCEF), policy and charging control (PCC) rules and an Event-Trigger parameter bound to a designated PCC rule sent by a policy control and charging rules function (PCRF) wherein the Event-Trigger parameter is further bound to identifiers (IDs) of IP flows in the designated PCC rule; wherein a manner of binding the Event-Trigger parameter to the designated PCC rule further comprises: carrying the Event-Trigger parameter and the designated PCC rule in a newly added parameter and indicating that the Event-Trigger parameter is bound to the designated PCC rule; and the Event-Trigger parameter is one or more Event-Trigger parameters, and the designated PCC rule carried in the newly added parameter is zero or more than one PCC rule; and detecting, by the PCEF network device, a status of IP flows which are denoted by respective IDs of the corresponding IP flows in the designated PCC rule.
