Method, system and policy and charging rules function (PCRF) for achieving reflective quality of service (Qos) mechanism

Abstract

The invention discloses a method, a system and a policy and charging rules function (PCRF) for achieving a reflective quality of service (QoS) mechanism. The method comprises the steps that in the process that an authentication is established or accessed in a tunnel, the 3rd generation partnership project authentication authorization accounting (3GPP AAA) server decides whether user equipment (EU) implements the reflective QoS mechanism or not; the PCRF obtains the decision result that whether the reflective QoS mechanism is implemented or not, generates corresponding strategy according to the decision result and provides the strategy to a broadband forum (BBF) access network for implementation. The method, the system and the PCRF for achieving the reflective QoS mechanism on one hand supports all the access scenes in which the 3GPP and the BBF are connected and communicated mutually, and on the other hand whether the UE implements the reflective QoS or not can be effectively controlled by a network, so that a legal UE can be protected and an illegal UE can be prevented from preempting the network resource.

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, Home Subscriber Server), Policy and Ch...

Problems solved by technology

[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
