Embodiment
For making purpose of the present invention, technical scheme and advantage clearer, below with reference to the accompanying drawing embodiment that develops simultaneously, the present invention is described in further detail.
The embodiment of the invention keeps the hPCRF address constant by the address information of transmitting hPCRF between distributed PCEF; Or, Anchor GW or AGW be by being saved in AAA/HSS with the hPCRF address information, and the PCEF relevant with this UE (comprising Anchor GW and AGW) passes through to AAA/HSS again and read and push away the hPCRF address information under hPCRF address information or the AAA/HSS and keep the hPCRF address constant for the relevant PCEF of this UE.
To achieve these goals, the embodiment of the invention has proposed a kind of implementation strategy and the system of the control of chargeing.
At first, mobile IP (the MIP that elder generation relates to the embodiment of the invention, Mobility IP) technology is briefly introduced, because the ambulant demand of UE is increasing, common IP technology can not have been supported moving of UE, therefore, on the basis of common IP technology, produced MIP, make UE when mobile, can not change its home address, i.e. related two IP addresses of UE, one is home address, another is a Care-of Address, UE obtains a home address by home network, in the time of outside UE moves to home network, obtain a Care-of Address by strange land agency (FA, Foreign Agent), and this Care-of Address informed home agent (HA, Home Agent), HA binds together home address and the Care-of Address of UE, and sets up the tunnel between HA and the Care-of Address, set up after the tunnel, HA just can send to the packet that mails to the UE home address Care-of Address of UE by the tunnel.
The MIP technology is divided into two big classes at present: the client moves IP (CMIP, Common ManagementIP) and proxy-mobile IP (PMIP, Proxy Mobility IP), and CMIP is based on the MIP technology of UE, just needs UE to participate in the technology of the binding procedure of MIP; PMIP is based on the MIP technology of network, does not need UE to participate in the process of MIP, and the behavior that network can be acted on behalf of UE replaces UE to initiate the MIP binding.
Fig. 4 is the system configuration schematic diagram of the embodiment of the invention implementation strategy and the control of chargeing.Referring to Fig. 4, this system comprises: AGW, Anchor GW, hPCRF and aaa server or home subscriber system (AAA/HSS, Authentication, Authorization, Accounting/Home SubscriberSystem), wherein,

The embodiment of the invention can be divided into that UE is attached to network and UE switches two kinds of situations between heterogeneous network.
Be attached to the situation of network for UE, if between the PCEF based on PMIP, then can keep the hPCRF address constant by the address information of between distributed PCEF, transmitting hPCRF; If between AGW and the Anchor GW based on CMIP, Anchor GW is by being saved in the hPCRF address information aaa server or home subscriber system (AAA/HSS, Authentication, Authorization, Accounting/Home Subscriber System), the PCEF relevant with this UE passes through to AAA/HSS again and reads and push away the hPCRF address information under hPCRF address information or the AAA/HSS and keep the hPCRF address constant for the relevant PCEF of this UE; When UE under roaming state, and AGW is when setting up session prior to Anchor GW, by the address information notice AGW of vPCRF with hPCRF.
For the situation of switching between the UE heterogeneous network, if between AGW and the Anchor GW based on PMIP, source AGW is saved in AAA/HSS with the address information of hPCRF, and from the address that AAA/HSS obtains hPCRF, the hPCRF address is constant before and after guaranteeing to switch when UE is carried out access authentication for target AGW; If between AGW and the Anchor GW based on CMIP, because UE has been saved in AAA/HSS with the hPCRF address when being attached to network, therefore, the PCEF of target AGW directly obtains the address of hPCRF from AAA/HSS when UE is carried out access authentication, thereby the hPCRF address is constant before and after guaranteeing to switch.
Fig. 6 is the schematic flow sheet of the embodiment of the invention one.In the present embodiment, UE is attached to network, and the PCEF of Access Network (AGW) sets up session earlier, and referring to Fig. 6, this flow process comprises:
Step 601, the UE access network, network carries out access authentication to UE;
Step 602, AGW is initiated to the session of hPCRF;
In this step, AGW obtain network to the access authentication of UE by information, be initiated to the session of hPCRF, obtain PCC rule information; If UE is roaming, AGW is initiated to the session of vPCRF, and vPCRF and hPCRF set up session then, and AGW obtains the hPCRF address by vPCRF.
After AGW obtains the hPCRF address, if based on PMIP, execution in step 603a～605a; If based on CMIP, execution in step 603b～607b.
Step 603a, AGW sends agent binding update messages to Anchor GW;
In this step, in agent binding update (PBU, the Proxy Binding Update) message that sends, carry the hPCRF address information by mobile option of redetermination (mobility option) parameter.
In this step, Anchor GW according to the hPCRF address information that receives to the hPCRF initiation session,
Step 605a, Anchor GW sends agent binding to AGW and responds (PBA, Proxy BindingAcklowege) message.
Step 603b, AGW stores the hPCRF address information into AAA/HSS;
Step 604b, UE sends Binding Update (BU, Binding Update) request message to Anchor GW;
In this step,, then in the Binding Update authentication process, obtain the hPCRF address information if carry out the Binding Update authentication at AAA/HSS, execution in step 606b, otherwise, execution in step 605b.
Step 605b, Anchor GW obtains relevant hPCRF address information from AAA/HSS;
In this step, relevant hPCRF address information is meant that AGW among the step 603b stores the hPCRF address information of AAA/HSS into.
Step 606b, Anchor GW and hPCRF set up session;
In this step, hPCRF sends to Anchor GW with PCC rule information, and Anchor GW carries out PCC rule information.
Step 607b, Anchor GW sends binding to UE and responds (BA, Binding Acklowege) message.
