Problems solved by technology

When the policy issued by the PCRF to the P-GW is not a Reflective QoS policy, even if the UE implements Reflective QoS on the uplink data, the P-GW will perform DSCP re-marking on the uplink data according to the policy issued by the PCRF, resulting in end-to-end end QoS cannot be achieved
In addition, if the network does not allow the terminal to perform Reflective QoS, but the terminal still performs Reflective QoS, the network cannot effectively control the illegal behavior of these UEs

[0089] Figure 4 Flow chart of PCRF formulating policies for UE accessing 3GPP core network through untrusted BBF access network and non-roaming scenario. Wherein, a GPRS (General Packet Radio Service, general packet radio service technology) tunnel protocol (GPRS Tunnel Protocol, GTP for short) is used between the ePDG and the P-GW. The process mainly includes the following steps:

[0090] Step 401: Optionally, after the UE accesses the BBF access network, it performs 3GPP-based access authentication, and the UE provides an International Mobile Subscriber Identification Number (IMSI for short) for access authentication.

[0091] Optionally, during the access authentication process, the 3GPP AAA (Authentication, Authorization, Accounting, verification, authorization and accounting) server decides whether the UE implements the Reflective QoS mechanism, and notifies the UE of the decision. Optionally, the UE first notifies the 3GPP AAA server of its capability indication of wh...

[0120] Figure 5 Flow chart of PCRF formulating policies for the UE to access the 3GPP core network through the untrusted BBF access network and in non-roaming scenarios. Wherein, the Proxy Mobile IPv6 (PMIPv6) protocol is adopted between the ePDG and the P-GW. The process mainly includes the following steps:

[0121] Steps 501-506 are the same as steps 401-406 of the fir tree, and will not be repeated here.

[0122] Step 507, the ePDG sends a gateway control session establishment message to the PCRF, which carries the UE's user ID, PDN ID, local IP address, and source UDP port number (if NA(P)T is detected, the message carries the source UDP port number ).

[0123] The ePDG may also send the decision obtained in step 506 by the network to determine whether the UE implements the Reflective QoS mechanism to the PCRF.

[0124] Step 508, the PCRF returns a gateway control session establishment confirmation message to the ePDG;

[0125] Step 509, after the ePDG selects the P-...

[0140] Figure 6 Shown is a flow chart of the PCRF formulating a policy when the UE accesses the 3GPP core network through the fixed broadband access network using the DSMIPv6 protocol. Among them, the fixed broadband access network is used as a trusted non-3GPP access network. The process mainly includes the following steps:

[0141] Step 601, optionally, the UE executes a 3GPP-based access authentication procedure that the fixed broadband access network participates in.

[0142] During the access authentication process, the 3GPP AAA server decides whether the UE implements the Reflective QoS mechanism, and notifies the UE of the decision. Optionally, the UE first notifies the 3GPP AAA server of its capability indication of whether to implement the Reflective QoS mechanism, and the 3GPP AAA server then determines whether the UE implements the Reflective QoS mechanism according to the capability indication.

[0143] Step 602, the UE obtains a local IP address from the fixed...

Abstract

The invention discloses methods and a system for achieving a QoS reflection mechanism. One method comprises that a policy and charging rule function (PCRF) entity devises and provides a QoS refection policy for a policy execution entity after judging that user equipment (UE) is accessed through a fixed broadband access network, and the policy execution entity executes the policy to the UE, wherein the QoS reflection policy comprises a policy and charging control (PCC) rule or a QoS rule. The other method comprises that the PCRF entity determines whether the US executes the decision of the QoS reflection mechanism and whether the QoS reflection policy is devised and provided for the policy execution entity according to the obtained network, and the policy execution entity executes the policy to the UE. According to the methods and the system for achieving the QoS reflection mechanism, the end-to-end QoS of the service of the UE which executes the QoS reflection can be guaranteed, and misconducts of the UE which is forbidden to execute the QoS reflection by the network can be controlled.

Description

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