Method and system for generating policy and charging rules

Abstract

The present invention provides a policy and charging rule generation method and system, relating to the field of communication technologies. One policy generation device controls service identification functions of multiple dedicated networks, so that the multiple dedicated networks share the same service identification rule library. The method comprises the steps that when a mobile terminal sends an attach request, a gateway device sends a policy and rule request to a policy generation device; the policy generation device generates multiple incomplete policy and charging rules according to service type parameters and status information of the mobile terminal, and sends the multiple incomplete policy and charging rules to the gateway device; the gateway device sends an inquire request to a service identification rule library device; the service identification rule library device searches data packet feature information of each application identifier and returns the data packet feature information of each application identifier to the gateway device; and the gateway device generates policy and charging rules. The method and system are applied to network control.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a method and system for generating policy and charging rules. Background technique [0002] At present, mobile networks are generally general-purpose networks, that is, all service traffic is transmitted on the same network, so it is difficult to guarantee the security and integrity of information flow. In order to ensure the security and integrity of the information flow, a private network is proposed in the prior art. The private network is only used to transmit the data flow between users who legally access the private network, and other users cannot access the private network, so the private network can guarantee the security and integrity of the information flow. However, if an independent transmission line is set between both ends of the private network communication, the cost of the private network will be very high. Therefore, the prior art proposes a virtualizati...

Problems solved by technology

In the case of parallel operation and control of multiple dedicated networks, the PCRF entities independently proposed by each dedicated network will make the policy and charging rules in the entire network inconsistent, and business identification rules need to be established separately according to the PCRF entities in each dedicated network Libraries also increase the complexity and cost of network operation and maintenance
