Problems solved by technology

From the above process, it can be seen that there is no HoA address information on the Non-3GPP AGW, and the address of the PCRF cannot be obtained, so the Gx session with the PCRF cannot be established, and the PCRF cannot implement policy control on the Non-3GPP network

Embodiment 1

[0052] see Figure 4 , Figure 4 It is an implementation flow chart of transferring policy control related information and establishing an IPCAN Session in Embodiment 1 of the method of the present invention. In this embodiment, the user equipment (UE, User Equipment) accesses the 3GPP network through the Non-3GPP network at home, and the CoA is not allocated by the AAA Server. The Non-3GPP AGW obtains the home PCRF (hPCRF) address and HoA address information corresponding to the IP CAN Session through the home AAA Server (hAAA), and initiates a session establishment request corresponding to the IP CAN Session to the hPCRF.

[0053] Step 401: UE attaches to the AGW.

[0054] Step 402: The AGW acquires the CoA corresponding to the UE's IP CAN Session.

[0055] Step 403: The AGW transfers the CoA to the UE.

[0056] Step 404: The AGW sends the AGW address and CoA to the hAAA by using the re-authentication request message.

[0057] Step 405: The PGW receives the UE's MIP reg...

Embodiment 2

[0063] see Figure 5 , Figure 5 It is an implementation flow chart of transmitting policy control related information and establishing an IPCAN Session in the second embodiment of the method of the present invention. In this embodiment, the UE accesses the 3GPP network through the Non-3GPP network at home, and the CoA is allocated by the AAA Server. The Non-3GPP AGW obtains the HoA address information corresponding to the IP CAN Session through the hAAA, and the AGW obtains the corresponding hPCRF address through the HoA address information, and initiates a session establishment request corresponding to the IP CAN Session to the hPCRF.

[0064] Step 501: UE initiates an attach request to AGW.

[0065] Step 502: The AGW initiates an authentication request of the UE to the hAAA, which includes the address of the AGW.

[0066] Step 503: The hAAA assigns the CoA corresponding to the IP CAN Session to the UE.

[0067] Step 504: The hAAA transmits the CoA to the AGW by using th...

Embodiment 3

[0076] see Figure 6 , Figure 6 It is an implementation flowchart of transferring policy control related information and establishing an IPCAN Session in Embodiment 3 of the method of the present invention. In this embodiment, the UE accesses the 3GPP network at home through the AGW1 of the Non-3GPP network and establishes a corresponding IP CAN Session, and the hPCRF address corresponding to the IP CAN Session has been stored in hAAA. When the UE attaches to AGW2, it transmits the HoA address information corresponding to the IP CAN Session to AGW2, and AGW2 initiates an authentication request to hAAA, which carries the HoA address information, and AGW2 obtains the hPCRF address corresponding to the IP CAN Session in the authentication response, and sends it to hPCRF initiates a session establishment request corresponding to the IP CAN Session.

[0077] Step 601: The UE accesses the 3GPP network at home through the AGW1 of the Non-3GPP network and establishes a correspondin...

Abstract

The invention provides a method of transmitting associated information of strategy control, a system and a device, comprising: acquiring corresponding identification of IP CAN Session, corresponding address of strategy control and charging function of IP CAN Session, and corresponding address accessed into a gateway of IP CAN Session; informing acquired PCRF address and the corresponding identification of IP CAN Session to AGW. According o the method, the system and the device, the associated information of the strategy control is transmitted between the associated entity of the strategy control, thereby building Gx dialog between PCRF and AGW, realizing strategy control of PCRF on non-3GPP network.

Description

technical field [0001] The invention relates to the field of policy control, in particular to a method, system and device for transmitting policy control related information. Background technique [0002] With the rapid development of wireless data services, higher requirements are put forward for the service quality and charging of data services. For this reason, Policy and Charging Control (PCC) is proposed in 3GPP. see figure 1 , figure 1 It is a schematic diagram of the PCC logical architecture proposed by the prior art 3GPP. Policy control related entities include: Policy Control and Charging Rules Function (PCRF, Policy Control and Charging Rules Function) entity, Policy and Charging Enforcement Function (PCEF, Policy and Charging Enforcement Function) entity, user subscription database (SPR, Subscription Profile Repository), and application layer functional entity (AF, Application Function), etc. Among them, the PCRF entity is used to determine the corresponding s...
