Fig. 6 is the present a kind of WiMAX system and the sketch map of PCC framework fusion; As shown in Figure 6; PCEF links to each other with functional entity among the ASN-GW through Interface R3; Link to each other with PCRF through the Gx interface, PCEF is as the protocol converter between the functional entity of PCRF and ASN-GW, PCEF can be further as the execution body of IP layer qos policy control; Being that PCEF will be that the message of Interface R3 sends to ASN-GW from the message conversion of the Gx interface of PCRF, will be that the message of Gx interface sends to PCRF from the message conversion of the R3 interface of ASN-GW.PCEF specifically can link to each other with functional entity SFA among the ASN-GW or data pathway function entity (DPF, Data Path Function) or charging proxy (Accounting Agent); Also can link to each other with SFA, DPF and charging proxy respectively.The PCC rule is used for that a server data stream is assigned to an IP connection access network network, and (IPConnectivity Access Network IP-CAN) carries.
In Fig. 6, also can the Function Decomposition of the PCEF of original 3GPP be distributed in the CSN network and ASN network of WiMAX system.
PCEF functional entity in the CSN network is called here and is inserted PCEF (I-PCEF), is responsible for transmitting interactive messages between interior policy and charging enforcement entity of ASN and the PCRF, carries out the mutual conversion of Interface R3 message and Gx interface message.If system supports the ability that the policy and charging enforcement entity in the ASN is directly communicated by letter with PCRF, comprise interface definition and the migration of carrying out body, can only keep the functional entity of PCEF in ASN.Policy and charging enforcement entity in the ASN network is divided into grappling PCEF, is called A-PCEF here, and service PCEF, is called S-PCEF here.A-PCEF is made up of policy and charging enforcement entities such as grappling SFA and/or Accounting Clients; As the anchor point of PCEF in the ASN network, be responsible for to receive the charging policy information that issues by the CSN network and pass to S-PCEF with the message that receives S-PCEF and be uploaded to the CSN network.S-PCEF is made up of policy and charging enforcement entities such as grappling DPF/FA, service SFA and/or charging proxies.S-PCEF comprises the function of service SFA and/or charging proxy as the policy and charging enforcement point of PCC rule.
In the PCC framework, for charging, use each layer independent counting, promptly application layer is done the application layer charging, and Access Network is done Access Network and is chargeed, and re-uses charge associated sign afterwards and carries out association to the ticket of each layer generation.
Set up in the process at Business Stream, qos policy and charging policy information all can send to PCEF by PCRF, and PCEF carries out the collection of charge information according to the requirement of charging policy and reports.
At PCRF when PCEF sends the PCC rule, the corresponding application layer charging identifier of each PCC rule and relevant rate information, and some the regular traffic flow informations of this PCC of application.Wherein, Rate information is preset information decision in information, the CAMEL-Subscription-Information among the AAA Server and/or the PCRF that is provided according to AF by PCRF; When PCEF and OCS are mutual, use this rate information request pre-payment quota, the charge information that reports at PCEF comprises this rate information.
In the PCC framework, the process that a utility cession of business is chargeed is:
At first; AF issues this utility cession corresponding media description information and application layer charging identifier to PCRF; Generally; The corresponding application layer charging identifier of utility cession, the corresponding a plurality of media description informations of utility cession, every group media descriptor can have medium type and bandwidth resources, the description of data stream information that is comprised and the largest request bandwidth information of an application layer sign, correspondence.
Then, after this utility cession that PCRF issues AF carries out authorisation process, send response message, wherein can comprise Access Network charging entity sign and one or more groups Access Network charging identifier information to AF.
A group of access net charging identifier information comprises: one or more groups description of data stream information that an Access Network charging identifier and this Access Network charging identifier are corresponding.Description of data stream information comprises media description information sequence number and inner data flow sequence number thereof.If do not spell out description of data stream information, then the Access Network charging identifier is to all data flow in should utility cession.
PCRF sends to PCEF and carries out for after this utility cession is provided with the PCC rule, and PCEF charges according to this PCC rule, generates charge information, carries out chargeing and the Access Network charging corresponding to the application layer of this utility cession through OCS or OFCS.
If PCC framework and WiMAX network merge, then PCEF is business when chargeing when carrying out the PCC rule, also should Accounting Client and/or charging proxy from ASN obtain charge information (also this implementation specifically not being narrated at present).
Though such scheme has proposed and need the Access Network charge information and the application layer charge information of same utility cession be associated, but do not propose how to be associated.In the such scheme; The charging policy information in the PCC rule is not issued in the Accounting Client and/or charging proxy among the ASN; Accounting Client among the ASN and/or charging proxy are when PCEF reports charge information; In theory can be according to fine granularity and with the mode collecting charging information of whole supports, support prepaid mode well, this can cause the waste of the resource and the bandwidth resources of WiMAX system.In the such scheme, also not describing to rate information, all is to carry out according to self strategy in the distribution to the calculating of user's rate and quota, is introducing newly when professional, need make amendment to strategy, is unfavorable for the introducing of business.Further, in such scheme, also not do not consider because the mobile meeting of MS causes Accounting Client and/or the variation of charging proxy among the ASN, thus the situation of the variation of the charge information that causes reporting.
In addition, such scheme is just chargeed to business according to the PCC rule by PCEF, and the entity in the WiMAX system can't charge to business, causes the policy and charging enforcement entity less at WiMAX, and the business of chargeing when need can produce bottleneck effect more for a long time.
In sum, also do not provide a kind of scheme that PCC framework fusion Business Stream to MS in the WiMAX system is chargeed at present.
