Problems solved by technology

[0004] However, in some application scenarios, when an operator needs to launch a new service (such as red envelope service) or the operator deploys a new data intelligent network on the existing service network and PCC architecture, how does the operator Business development without changing the existing business network and PCC architecture still needs to be solved

Embodiment 1

[0071] This embodiment describes that the user accesses from E-UTRAN (EvolvedUniversalTerrestrialRadioAccessNetwork, evolved unified terrestrial radio access network) and uses PMIPv6 protocol between S-GW (serving gateway) and P-GW (packet data gateway), or UE When accessing the 3GPP system from a trusted non-3GPP network or an untrusted non-3GPP network and using the PMIPv6 protocol between A-GW (Security Gateway) / ePDG (Evolved Packet Data Gateway) and P-GW, establish an IP-CAN session process and the PCRF selection process. DRA is RedirectAgent, based on image 3 or Figure 4 The structure shown is implemented. Figure 5 It is a flowchart of Embodiment 1 of the selection method of PCRF of the present invention, such as Figure 5 As shown, it specifically includes the following steps 401-417:

[0072] Step 401: The UE accesses through E-UTRAN or accesses from a trusted non-3GPP network and requests to establish an IP-CAN session. The S-GW or A-GW / ePDG receives a message r...

Embodiment 2

[0092] This embodiment describes that in a non-roaming scenario, the UE accesses from E-UTRAN and the GTP ((GPRSTunnelProtocol, General Packet Radio Service Technology Tunneling Protocol) When a non-3GPP network or an untrusted non-3GPP network accesses the 3GPP system and the GTP protocol is used between A-GW / ePDG and P-GW, the process of establishing an IP-CAN session and the selection process of PCRF. DRA is RedirectAgent, based on image 3 or Figure 4 The structure shown is implemented. Figure 6 It is a flow chart of Embodiment 2 of the PCRF selection method of the present invention, specifically including the following steps 501-511:

[0093] Step 501: The UE accesses the EPS system through E-UTRAN or non-3GPP, and the P-GW receives a message requesting to establish an IP-CAN session, and the message carries a user ID and a PDN ID;

[0094] Step 502: The PCEF located at the P-GW sends an IP-CAN session establishment instruction message to the DRA, and the message carr...

Embodiment 3

[0107] This embodiment describes that the user accesses from the E-UTRAN and the PMIPv6 protocol is used between the S-GW and the P-GW, or the UE accesses the 3GPP system from a trusted non-3GPP network or an untrusted non-3GPP network and the A-GW / When using PMIPv6 protocol between ePDG and P-GW, establish IP-CAN session process and PCRF selection process. DRA is ProxyAgent, based on image 3 or Figure 4 The structure shown is implemented. Figure 7 It is a flow chart of Embodiment 3 of the PCRF selection method of the present invention, specifically including the following steps 601-617:

[0108] Step 601: The UE accesses through E-UTRAN or requests to establish an IP-CAN session from a trusted non-3GPP network, and the S-GW or a trusted non-3GPP access gateway (A-GW) receives the request to establish an IP-CAN session message, the message carries the user identifier and the PDN identifier;

[0109] Step 602: The BBERF located at the S-GW or A-GW sends a gateway contro...

Abstract

The invention provides a method and apparatus for selecting a policy and charging rules function. The method comprises the steps of acquiring, by a diameter routing agent (DRA), subscription information of a specific business subscribed by a user from a subscription profile Repository (SPR) or a business operation support system (BOSS); and selecting, by the DRA, a policy charging rules function (PCRF) supporting the specific business for user equipment (UE) or an IP connectivity access network (IP-CAN) session according to the subscription information of the specific business. The invention can support selection of different PCRFs for different businesses.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and device for selecting policy and charging rule functions. Background technique [0002] figure 1 It is a schematic diagram of a policy and charging control architecture (Policy and Charging Control, referred to as PCC) defined by the 3rd Generation Partnership Project (3rd Generation Partnership Project, referred to as 3GPP) in related technologies, as shown in figure 1 As shown, the Policy and Charging Rules Function (Policy and Charging Rules Function, PCRF for short) is the core of the entire PCC architecture. To formulate the control strategy, the PCRF needs to combine the service information received from the application function (ApplicationFunction, referred to as AF), the user subscription information received from the user subscription database (SubscriptionProfileRepository, referred to as SPR), and the strategy configured by the operator. The PCRF will issue the...
