A method, system and pcrf for realizing reflective qos mechanism

Abstract

The invention discloses a method, a system and a policy and charging rule function entity (PCRF) for realizing a reflective quality of service (QoS) mechanism. Plan Authentication Authorization Accounting (3GPP AAA) server to decide whether user equipment (UE) implements reflective quality of service (QoS) mechanism; PCRF obtains the decision result of whether to implement reflective QoS mechanism, formulates corresponding strategies according to the decision result and provides it to broadband forum (BBF) access network implementation. On the one hand, the present invention supports all access scenarios of 3GPP and BBF interconnection; on the other hand, the network can effectively control whether the UE implements the reflective QoS mechanism, can protect legal UEs, and prevent illegal UEs from seizing network resources.

Description

technical field [0001] The present invention relates to the field of interconnection and intercommunication technology of the 3rd Generation Partnership Project (3GPP, 3rd Generation Partnership Project) and Broadband Forum (BBF, Broadband Forum), in particular to a method for realizing a reflective Quality of Service (QoS, Quality of Service) mechanism , system and PCRF. Background technique [0002] The structure of the existing 3GPP evolved packet system (EPS, Evolved Packet System) is as follows: figure 1 shown in figure 1 The EPS network architecture shown in the non-roaming scenario includes an Evolved Universal Terrestrial Radio Access Network (E-UTRAN, Evolved Universal Terrestrial Radio Access Network), a Mobility Management Entity (MME, Mobility Management Entity), and a service gateway (S-GW, Serving Gateway), Packet Data Network Gateway (P-GW, Packet Data Network Gateway, also known as PDN GW), Home Subscriber Server (HSS, HomeSubscriber Server), Policy and Cha...

[0010] Secondly, in this method, the network cannot effectively control the UE that does not follow the network decision. Even if the network instructs the UE not to implement the reflective QoS mechanism, the UE still implements the reflective QoS mechanism, and the network cannot prevent the UE from seizing the resources of other UEs.

[0011] At present, for the scenario where the UE accesses services through the BBF access network, the Reflective QoS mechanism can be used to realize the QoS control of the uplink data of the service data flow. The network can be controlled accordingly
