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
The present invention relates to the policy control field, particularly the method, system and device of controlling related information using transmission policy.
Background technology
Along with the fast development of wireless data service, the service quality and the charging of data business are also had higher requirement, for this reason, strategy has been proposed and the control (PCC) of chargeing in 3GPP.Referring to Fig. 1, the PCC logical architecture schematic diagram that Fig. 1 is proposed for prior art 3GPP.The policy control related entities comprises: policy control and charging rule functions (PCRF, Policy Control and Charging Rules Function) entity, strategy and charge execution function (PCEF, Policy and Charging Enforcement Function) entity, user-subscribed database (SPR, Subscription Profile Repository) and application level function entity (AF, Application Function) etc.Wherein, the PCRF entity is used for the decision corresponding strategy such as restriction, carrier policy, user contracting data and the current ongoing business information of user according to user access network, and this strategy is offered PCEF, carries out these strategies by PCEF.The PCEF entity is usually located on the PGW in the 3GPP network, is used to carry out that PCRF issues or the strategy of appointment.Wherein, have the Gx interface between PCRF entity and the PCEF entity, this interface makes PCRF can dynamically control PCEF and goes up the policy charging rule of carrying out.
When mobile terminal UE start access network promptly adheres to, can initiate to set up IP to PCEF and be communicated with access network (IP CAN Session, IP Connect Access Network) request, set up the corresponding Gx session of IP CAN Session between PCEF and the PCRF, PCRF gives PCEF with the policy distribution that generates, and realizes the policy control to the 3GPP network.
Also have the PCEF entity in non-3GPP (Non-3GPP) networks such as (WiMAX) of micro-wave access global inter communication technical forum, the PCEF entity in the Non-3GPP network is usually located on the AGW in the Non-3GPP network.Referring to Fig. 2, Fig. 2 sets up process for prior art subscriber equipment (UE) adhering to IP CAN Session during by Non-3GPP network insertion 3GPP network.When UE is attached to the Non-3GPP network, AGW is that UE distributes a Care-of Address (CoA, Care-of Address), UE uses this CoA to initiate mobile IP protocol (MIP to PGW, Mobile IP Protocol) register requirement, PGW is home address (HoA for the IP address of user's distributing IP CAN Session correspondence, Home Address) address information, with CoA and the binding of HoA address information, and, initiate the Gx session of IP CAN Session correspondence to PCRF and set up request according to the address that information such as HoA address information are obtained PCRF.From said process as can be seen, do not have the HoA address information on the Non-3GPP AGW, the address that can not obtain PCRF, therefore can't set up and PCRF between the Gx session, PCRF can't realize the policy control to the Non-3GPP network.
Summary of the invention
The embodiment of the invention proposes a kind of method of controlling related information using transmission policy, this method can be between the policy control related entities controlling related information using transmission policy, make between AGW and the PCRF and can set up the Gx session, thereby make PCRF can realize policy control the Non-3GPP network.

Step 301: the address that obtains the AGW of the address of PCRF of IP CAN Session corresponding identification, IP CAN Session correspondence and IP CAN Session correspondence;
Step 302: with address and the IP CAN Session corresponding identification notice AGW of the described PCRF that obtains.
Wherein, the above-mentioned step of obtaining and notifying can be by authentication, authorize accounting server (AAA Server) and carry out.
In the said method, described IP CAN Session corresponding identification can be the HoA address information of IP CAN Session correspondence, in following examples, abbreviate the HoA address information of IP CAN Session correspondence as the HoA address information, be described as IP CAN Session corresponding identification.
After the said method step, just can set up the pairing Gx session of IP CAN Session, thereby realize the policy control of PCRF the Non-3GPP network.The process of specifically setting up the Gx session is:
After described AGW receives the address and described IP CAN Session corresponding identification of described PCRF, further comprise: request message is set up in the Gx session that sends IP CAN Session correspondence to PCRF, carry described IP CAN Session corresponding identification in this message, PCRF sets up the Gx session according to the described message and the AGW that receive.
In the above-mentioned steps 301, the step of address that AAA Server obtains the PCRF of HoA address information and IP CAN Session correspondence can comprise: the address that receives the PCRF of HoA address information and IP CANSession correspondence from the anchor point entity.The anchor point entity can be PGW.The address of above-mentioned HoA address information and PCRF can adopt authentication request message, re-authentication requests message or gateway address update inquiry information to transmit.
In the above-mentioned steps 301, the step of address that AAA Server obtains the AGW of IP CAN Session correspondence can have several different modes.Wherein:
Mode one: comprise three steps:
(1) if the CoA of HoA address information correspondence is distributed by AAA Server, then receive the address of AGW from AGW, the CoA that address and the HoA address information of described AGW is corresponding is related; Otherwise,, then receive the address of the AGW of CoA and this CoA correspondence from AGW if the CoA of HoA address information correspondence is distributed by AGW.Specifically can adopt authentication request message or re-authentication requests message to transmit.
(2) receive the HoA address information of IP CAN Session correspondence and the CoA of HoA address information correspondence from the anchor point entity.The anchor point entity can be PGW.Can adopt authentication request message, re-authentication requests message or gateway address update inquiry information to transmit.
Above-mentioned steps (1) and (2) are order in no particular order.
(3) AAA Server is according to the address of related IP CAN Session of the CoA that receives in the above-mentioned steps and corresponding AGW thereof, thereby obtains the address of the AGW of IP CAN Session correspondence.
Mode two:
From address and the HoA address information of AGW reception AGW, the address that obtains the AGW of IP CAN Session correspondence.
Mode three:
Perhaps, receive the address of AGW and corresponding user's sign (User-ID), with the address correlation of described AGW IP CAN Session, the address that obtains the AGW of IP CAN Session correspondence to described user from AGW.
In the above-mentioned steps 302, with the address of the PCRF that obtains and the mode of HoA address information notice AGW be: address and the HoA address information of the described PCRF that obtains are sent to AGW.Wherein, the address of PCRF and HoA address information can adopt discrimination weight message to transmit.
