Here, the illustrative embodiment of the present invention The examples and the description thereof are intended to explain the present invention, but are not intended to limit the invention.

Figure 1 is based on the definition of 3GPP defined in the TS 23.402 specification? The network architecture diagram of the 55/58 interface of Figure 1 is shown in Figure 2 for the network architecture diagram of the S2a and S2b interfaces of non_3GPP access defined by the 3GPP in TS 23.402. As shown in Figure 1, 2, where:

The Policy and Charging Rules Function (PCRF) is mainly used to complete the policy decision and flow-based charging control. The entity is based on the carrier policy, user subscription data, and the service currently being performed by the user. The information determines the corresponding strategy and provides the policy to PCEF/BBERF, which is executed by PCEF. The PCEF is a functional entity integrated by the PDN-GW. The BBERF is a functional entity integrated in the S-GW or non_3GPP access network. The policy includes the detection rules of the service data flow, whether it is gated, QoS, and flow-based charging rules. The strategy here can be a PCC rule or a separate attribute. For the sake of simplicity, the strategy is not differentiated in this article.

The PCEF (Policy and Charging Enforcement Function) is mainly used to complete the detection of the service data flow, the execution of the policy, and the flow-based charging. The entity is integrated in the PDN-GW for execution. The policy that is sent or specified by the PCRF is specifically to perform the detection and measurement of the service data flow, to ensure the QoS of the service data flow, the user plane traffic processing, and the session management of the trigger control plane.

BBERF (Bearer Binding and Event Report Function), which is integrated in the S-GW or Trusted Non-3GPP Network MAG (Mobile Access Gateway) or Un-trusted Non_3GPP Network The EPDG (Evolved Packet Data Gateway) is configured to perform bearer binding on the service flow according to the QoS information of the service flow provided by the PCRF, and verify the uplink bearer binding, and report the event to the event trigger according to the event trigger. The PCRF maps the downlink service flow to the corresponding bearer according to the TFT (Traffic Flow Template) of the service flow provided by the PCRF.

The S5/S8 reference point is an interface for the transfer of control plane and user plane data between the S-GW and the PDN-GW. Based on the PM5-based S5/S8 interface, the control plane is the PMIPV6 protocol stack message, and the user plane is based on the user. GRE tunnel. In the case of multiple PDN connections for the same user, the S-GW may have multiple S5/S8 interfaces connected to multiple PDN-GWs.

The S2a reference point is an interface for the transfer of control plane and user plane data between the trusted non-3GPP network MAG device and the PDN-GW. The reference point can be based on the PMIP protocol or the MIP protocol.

The S2b reference point is the interface between the control plane and user plane data between the un-trusted non-3GPP network ePDG device and the PDN-GW. The reference point is based on the PMIP protocol.

The Gx (S7) reference point enables the PCRF to dynamically adjust the policy control and charging related functions performed by the PCEF, such as establishing, maintaining, and terminating IP-CAN sessions; the PCEF requests PCC rules from the PCRF; the PCRF provides PCC rules to the PCEF; -CAN bearer setup mode, etc. The PCEF can also provide IP-CAN related information to the PCRF through this reference point, and report bearer events. This reference point uses the Diameter protocol defined by the IETF (Internet Engineering Task Force).

The Gxa/Gxb/Gxc reference point is used by the PCRF to deliver QoS information of the service flow to the BBERF, including an IP filter for identifying the service data flow, such as a source IP address, a destination IP address, a protocol type, a source port number, and a destination port. Number, etc.; QoS information of the service flow, such as QCI, ARP, GBR, MBR; and BBERF event triggers report events to the PCRF. This reference point uses the Diameter protocol defined by the IETF.

Referring to FIG. 1 and FIG. 2, the Gx reference point is between the PCEF and the PCRF. In the EPS network structure based on the PMIP/MIP interface, the information exchanged between the PCEF and the PCRF includes: the PCRF sends the charging rule to the PCEF, and the service The control policy, the PCEF performs charging and control of the service flow according to the charging rule and the control policy delivered by the PCRF; the PCRF configures, updates, and deletes the PCC rule to the PCEF; the PCEF reports the user plane event to the PCRF. Between BBERF and PCRF is the Gxx reference point. When BBERF is integrated into the S-GW in the 3GPP network, it is the Gxc interface. When BBERF is integrated in the trusted non-3GPP access network, it is the Gxa interface; when BBERF is integrated in non-trust The non-3GPP access network is the Gxb interface. The information exchanged between the BBERF and the PCRF includes: PCRF to BFEEF configuration, update, delete QoS rules BjF reports the user plane event to the PCRF; the event report is transmitted between the BBERF and the PCRF via the PCRF.

Gateway; or MAG integrated in a trusted non-3GPP access network; or ePDG integrated in an untrusted non-3GPP access network. Referring to FIG. 4, the method in this embodiment mainly includes:

401: Receive a service flow on a downlink PMIP/MIP interface link.

402: Statistics the traffic of the service flow and the active packet loss traffic; 403: The traffic of the service flow is decremented with the active packet loss traffic as the reported downlink service statistics traffic.

In this embodiment, the PMIP/MIP interface includes a PMIP-based S5 interface, an S8 interface, an S2a interface, and an S2b interface, or a MIP-based S2a interface. After receiving the service flow sent by the interface, the function entity that implements the method of the embodiment collects the traffic of the service flow. However, due to resource limitations, for example, the bearer bandwidth is insufficient, the downlink buffer queue is full, and the ECM-IDLE The downlink data buffer is discarded after the paging UE fails in the state. Therefore, the function entity also actively discards the traffic according to the service flow statistics, so as to obtain the traffic of the service flow actually received by the user, that is, the downlink service flow and the active packet loss. The difference in traffic is the reported downlink traffic statistics.

{ TimeStamp— Value }

氺 [Service_ Identifier]

The SDFVolume-Value field defines the downstream traffic of the service flow; the TimeStamp-Value field defines the timestamp of the downstream traffic statistics; and the Service-Identifier field defines the service flow. Since the 3GPP 29.212 specification defines an event report indication message Event-Report-Indication AVP to pass BBERF to PCEF information, such as RAT-TYPE, the above-mentioned new event SDFVOL is added to the AVP of the Event-Report-Indication - OF—MINUS, to transmit downlink traffic statistics to the PCEF. The AVP is defined as follows:

Event-Report-Indication:: = < A VP Header: xxx >

* [Event-Trigger]

[SDFVOL— OF— MINUS]

* [AVP] The method in this embodiment collects the actual downlink traffic flow according to the traffic flow and the active packet loss traffic on the downlink PMIP/MIP interface link, and passes the Gxa after the service flow reports the timer expires or the service flow ends. The event report indication message on the interface or the Gxb interface or the Gxc interface notifies the policy and the charging execution entity PCEF of the statistical downlink traffic flow, so that the PCEF performs corresponding verification on the user service flow charging, and the downlink is resolved to the user. The problem of multi-billing of business traffic has improved customer satisfaction.
