Description

Method and device for enabling policy and charging control Technical field

This document relates to the field of wireless communication technologies, and in particular, to a method and apparatus for enabling policy and charging control.

Background technique

1 is a schematic diagram of a system architecture of an existing Evolved Packet System (EPS). As shown in FIG. 1, an EPS of a 3rd Generation Partnership Project (3GPP) includes: an evolved universal E-UTRAN (Evolved Universal Terrestrial Radio Access Network), Mobility Management Entity (MME), Serving Gateway (S-GW, Serving Gateway), Packet Data Network Gateway (P-GW, Packet) The Data Network Gateway, the Home Subscriber Server (HSS), the 3GPP Authentication and Authorization Accounting (AAA) server, the Policy and Charging Rules Function (PCRF), and other supporting nodes.

The MME is used for control planes such as mobility management, non-access stratum signaling processing, and user mobility management context management; the S-GW is an access gateway device connected to the E-UTRAN, and is used in The data is forwarded between the E-UTRAN and the P-GW, and is responsible for buffering the paging waiting data; the P-GW is a border gateway of the EPS and the Packet Data Network (PDN), and is used for the access of the PDN and Forward data and other functions between EPS and PDN.

The EPS supports interworking with non-3GPP networks and implements interworking with non-3GPP networks through the S2a/b/c interface. Non-3GPP networks include trusted non-3GPP networks and untrusted non-3GPP networks. The IP access of the trusted non-3GPP network can be directly connected to the P-GW through the S2a; the IP access of the untrusted non-3GPP network needs to be connected to the P-GW by the Evolved Packet Data Gateway (ePDG). The interface between the ePDG and the P-GW is S2b. The user equipment (UE, User Equipment) can also be connected to the P-GW through the S2c interface using the DSMIPv6 protocol.

If the EPS system supports the policy and charging rules of the PCRF of the Policy and Charging Control (PCC), then the PCRF passes the receiving interface Rx and the operation. The service network of the Internet Protocol (IP) is connected to obtain service information. In addition, the PCRF is connected to the gateway device in the network through the Gx/Gxa/Gxb/Gxc interface, and is responsible for initiating the establishment of the IP-specific bearer and ensuring the service data. Quality of Service (QoS), and charge control.

The Policy and Charging Enforcement Function (PCEF) is located in the P-GW, and the PCRF and the P-GW exchange information through the Gx interface. When the interface between the P-GW and the S-GW is based on Proxy Mobile IP (PMIP), there is a Bearer Binding and Event Report Function (BBERF) in the S-GW, and S- The GW and the PCRF exchange information through the Gxc interface. When a trusted non-3GPP network accesses, a BBERF is also resident in the trusted non-3GPP access gateway, and the trusted non-3GPP network access gateway exchanges information with the PCRF through the Gxa interface. When the untrusted non-3GPP network accesses, the BBERF also resides in the ePDG, and the ePDG and the PCRF exchange information through the Gxb interface. The Gxa/Gxb/Gxc interface between BBERF and PCRF is collectively referred to as the Gxx interface. On the Gxx interface and the Gx interface, BBERF and PCEF are clients, and PCRF is a server. When a user accesses the network or a network switch occurs, BBERF and PCEF need to determine whether PCC is enabled and request policy control from the PCRF.

In the related art, the BBERF/PCEF can only decide whether to open the PCC and access the PCRF based on the currently accessed PDN identifier or the user identification number segment and its own configuration information, and the operator generally hopes to only sign some packages (such as the limit). The PCC is only turned on when the speed package is set to reduce the burden on the BBERF/PCEF and the PCRF.
