Problems solved by technology

In the process of implementing the present invention, the inventor found that in the prior art, hPCRF cannot identify which policy model to use, which will cause PCRF to issue wrong policy content to PCEF, and PCEF cannot implement the shortcomings of the PCRF issued policy

Embodiment 1

[0053] Wherein, the policy model information is policy model indication information, which can explicitly indicate which policy model should be adopted by the PCRF, and its value is off path or on path. The PCRF directly decides whether to use the offpath method or the on path method to deliver the policy information according to the indication value. For example, at this time, the interface message between the PDN GW and the PCRF needs to be extended. For example, if it is a Diameter protocol, a new attribute needs to be added to the credit control request (Credit Control Request, CCR) message reported by the PDN GW A value pair (attribute value pair, AVP) is used to represent the policy model indication, which can be called "POLICY-MODEL", and can have the following values: OFF PATH (0), ON PATH (1); PCRF determines the value according to the value Confirm the delivery method to be used. Alternatively, a new AVP may be added in the Re-Auth Response (RAA) message to respond ...

Embodiment 2

[0061] Among them, the policy model information is the mobility management protocol type between the PDN GW and the access side entity: its value is divided into two types: GTP and MIP, and MIP can be further subdivided into DSMIP, PMIP, MIPv4FACoA, etc.; when PCRF receives If the protocol type is MIP, use the off path method to deliver policy information. If the received protocol type is GTP, use the on path method to deliver policy information. Access-side entities include access-side gateways and terminals.

[0062] Then, in steps S34 and S36, for example, the interface message between the PDN GW and the PCRF is extended. If it is a Diameter protocol, a credit control request (Credit ControlRequest, CCR) message reported by the PDN GW needs to be added. The new AVP is used to represent the interface protocol field between the PDN GW and the access side entity, we call it ACCESS-PROTOCOL-TYPE, which can have the following values: MIP(0), GTP(1). Alternatively, a new AVP ma...

Embodiment 3

[0065] Wherein, the policy model information is a radio access (RAT) type. The value of the RAT type can be 3GPP-UTRAN, 3GPP-GERAN, 3GPP-GAN, IWLAN, etc., which can contain information supporting policy models, such as 3GPP-UTRAN, 3GPP-GERAN and 3GPP-GAN implicitly support onpath policies Model. Similarly, the policy model information can be carried in a CCR message, an RAA message or a newly defined message.

[0066] In step S38 and step S39, if the RAT type received by the PCRF is 3GPP-UTRAN, 3GPP-GERAN, 3GPP-GAN, the on path method can be adopted to issue policy information; if the RAT type received by the PCRF is non-3GPP If the wireless access type is not reported or the RAT type is not reported, then the offpath method can be used to deliver the policy information. Wherein, for the specific content of issuing policy information in an on path manner or an off path manner, refer to the description of Embodiment 1, and details are not repeated here.

Abstract

The embodiment of the invention discloses a method for reporting the strategic model information. The method comprises the following steps: the strategic model information is obtained; and the strategic model information is transmitted to a strategy and charging regulation functional entity. The strategic model information is used for the strategy and charging regulation functional entity which issues the strategic information to a strategy and charging executing functional entity. The embodiment of the invention also discloses a PDN gateway and a PCRF. The method and the device report the strategic model information to the PCRF by a PCEF entity (such as the PDN gateway) so as to lead the PCRF to be capable of knowing the issuing modes needed to be adopted according to the information andtransmitting the strategic information to the PCEF entity by the issuing mode, and has important application value in the aspects of promotion and application and the like of SAE.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and equipment for reporting policy model information. Background technique [0002] The System Architecture Evolution (SAE) defined by The 3rd Generation Partnership Project (3GPP) in TS23.041 and TS23.402, and optimizes and enhances the wireless packet access network architecture , please refer to the following figure 1 , shows an existing non-roaming SAE network architecture, and please refer to the following figure 2 , shows an existing roaming SAE network architecture. [0003] Before introducing the specific network elements in the two drawings, the following terms are explained first: [0004] IP Continuity Access Network (IP Connectivity Access Network, IP-CAN): When the user roams in the access network (when the location changes), the access network that can still preserve the IP service continuity (that is, not interrupt the service), such as the general Wireless ...
