Abstract
The invention relates to a method, a system and a policy control and charging roles function (PCRF) for realizing backward quality-of-service (QoS) insurance and content charging. The method comprises the steps of receiving a strategy and charging control request which is initialized by an application in response to service initiation of the application, wherein the strategy and charging control request carries a service identification and quintuple information which corresponds with the service identification; acquiring a corresponding PCC strategy according to the service identification; and transmitting a correspondence between the PCC strategy and the quintuple information to a policy control and charging enhancement function (PCEF), thereby realizing QoS insurance and content charging for different services. The method, a system and a policy control and charging roles function make the policy control and charging enhancement function (PCEF) correctly perceive different services.
Description
Technical field
The disclosure relates to communication technical field, especially, relate to one and realize backward QoS (QualityofService, service quality) ensure and the method for content charging, system and PCRF (PolicyControlandChargingRulesFunction, policy control and charging rule functions).
Background technology
A significant capability of intelligent pipeline controls based on the differentiation strategy and charging that the deep layer perception of service traffics are realized to business dimension.Now general business recognition method configures predefined traffic identification rule at PCEF, distinguishes different business by object IP address or 7 layers of DPI (DeepPacketInspectio, deep-packet detection) technology.But there is some problem following in this scheme based on predefine traffic identification rule: (1), can be increasing to the maintenance difficulties of PCEF along with the increase of number of services and business renewal frequency, (2) different ICP (InternetContentProviderInternet, content supplier) same CDN (ContentDeliveryNetwork may be rented, content distributing network) server, when so user uses different business, because content is in same CDN server, cause object IP address the same with port numbers, and then cause PCEF (PolicyControlandChargingEnforcementFunction, policy control and charge execution function) carrying out differentiated service by object IP address can be failed, thus correct backward QoS guarantee cannot be realized, the policy and charging control of the business dimensions such as content charging.
