Embodiment 1

[0037] This embodiment describes when the UE is within the coverage of 3GPP, and the 3GPP core network adopts the EPC architecture; in the EPC, the interface protocol between the S-GW and the P-GW is based on PMIP. This embodiment describes the process of UE initiating a session. The UE initiates a session establishment request, the P-GW selects a PCRF through the DRA, and the selection result is saved in the DRA, and then the S-GW and the AF select the same PCRF through the DRA. The flow chart of this embodiment is shown in Figure 2, described as follows:

[0038] The processing flow of P-GW is as follows:

[0039] 202. Before the P-GW informs the PCRF that the IP-CAN session is established, it queries the locally saved association relationship table. If the PCRF address corresponding to the IP-CAN session is not found, it sends a message indicating the establishment of the IP-CAN session to the DRA, and informs the IP -CAN session establishment, obtain PCRF address, the me...

Embodiment 2

[0056] This embodiment describes when the UE is in a trusted non-3GPP coverage area, and the 3GPP core network adopts the EPC architecture. The MIP protocol is used between the trusted non-3GPP access gateway and the P-GW to establish a MIP tunnel. This embodiment describes that the UE initiates an IP-CAN session. During the process, the P-GW selects a PCRF through the DRA, and the selection result is stored in the DRA. Afterwards, the trusted non-3GPP access gateway and the AF select the same PCRF through the DRA. The flowchart of this embodiment is shown in Figure 3, and each step is described as follows:

[0057] The processing flow of P-GW is as follows:

[0058] 302. Before the P-GW informs the PCRF that the IP-CAN session is established, it queries the locally saved association relationship table. If the PCRF address corresponding to the IP-CAN session is not found, it sends a message indicating that the IP-CAN session is established to the DRA, and informs the IP -CAN...

Embodiment 3

[0073] This embodiment describes when the UE is in an untrusted non-3GPP coverage area, and the 3GPP core network adopts the EPC architecture. This embodiment describes that the UE initiates an IP-CAN session, during which the P-GW selects a PCRF through the DRA, the DRA stores the selection result, and then the AF selects the same PCRF through the DRA. The flow chart of this embodiment is shown in Figure 4, and each step is described as follows:

[0074] 402. Before the P-GW informs the PCRF that the IP-CAN session is established, it queries the association table stored locally. If the PCRF address corresponding to the IP-CAN session is not found, it sends a message indicating the establishment of the IP-CAN session to the DRA, and informs The IP-CAN session is established, and the PCRF address is obtained, and the message includes UE ID, UE IP Address, and PDN ID;

[0075] 404. After receiving the message, the DRA uses the UE ID, UE IP Address, and PDNID contained in the me...

Abstract

The invention discloses a selection method of a strategy under non-roaming state and an accounting rule function server, which realized that the PCC strategy of each IP-CAN conversion is decided only by a PCRF. The method comprises that an association relation list is established on a Diameter routing agent DRA, the association relation list stores an IP communication access network IP-CAN conversation information and corresponding strategy and accounting rule function server PCRF address information, a strategy and accounting execution function entity RCEF and a gateway control function entity GWCF obtain the PCRF address information corresponding to the IP-CAN conversation through the DRA so as to achieve the subsequent processing when a strategy which aims at the IP-CAN conversation and an accounting control PCC strategy are demanded or updated to the PCRF or when an application function entity AF demands sending down the application or service information to the PCRF.

Description

technical field [0001] The invention relates to a method for selecting a policy and charging rule function server in a wireless network. Background technique [0002] The 3GPP evolved packet system (EPS, Evolved Packet System) consists of evolved UTRAN (E-UTRAN, Evolved Universal Terrestrial Radio Access Network), MME (Mobility Management Entity), S-GW (Serving Gateway, Serving Gateway), PDN GW (Packet Data Network GateWay, data network gateway, P-GW for short), HSS (Home Subscriber Server), 3GPP AAA server (3GPP Authentication Authorization Accounting Server), PCRF (Policy and Charging RulesFunction, strategy and Billing rule function server), and other supporting nodes. Among them, MME is responsible for mobility management, non-access stratum signaling processing, user mobility management context management and other control plane related work; S-GW is an access gateway device connected to E-UTRAN, between E-UTRAN and PDN The GWs forward data and are responsible for cac...
