A method and a system of realizing event detection are provided, which detect a status of an Internet Protocol (IP) connectivity access network (IP-CAN) bearer corresponding to a policy and charging control (PCC) rule by binding an Event-Trigger parameter to the PCC rule, thereby realizing small-granularity detection for the specific PCC rule and reducing the load of the system. Furthermore, a status of the IP-CAN bearer or an IP flow is realized by binding the Event-Trigger parameter to an IP-CAN identifier (ID) or an IP flow ID, so as to avoid the problem about too large granularity of the binding of event detection and IP-CAN session and reduce the burden of the IP-CAN bearer detection and message exchange.
A method of realizing event detection, comprising:
A network device configured as a policy and charging enforcement function (PCEF), configured to receive a policy and charging control (PCC) rule bound to an Event-Trigger parameter, wherein the Event-Trigger parameter is further bound to identifiers (IDs) of IP flows in a designated PCC rule and further configured to detect a status of IP flows denoted by respective IDs of the corresponding IP flows in the designated PCC rule;
A system of realizing event detection, at least comprising a network device configured as a Policy and Charging Enforcement Function (PCEF) and a network device configured as a Policy control and Charging Rules Function (PCRF) in another server in the network, wherein
