Reporting Function, bearing binding and event reporting function entity) 18.
Wherein, information exchange is carried out using interface between above-mentioned each functional entity, such as establishes session etc..
It is Rx interface between PCRF13 and AF12 for example, being Sp interfaces between PCRF13 and SPR11,
It is Gxx interfaces between PCRF13 and BBERF18, is Gx interfaces between PCRF13 and PCEF14,
It is Sd interfaces between PCRF13 and TDF15, is Sy interfaces between PCRF13 and OCS16, PCEF14
Be Gy interfaces between OCS16, be Gyn interfaces between TDF15 and OCS16, TDF15 with
It is Gyn interfaces between OFCS17, is Gz interfaces between OFCS17 and PCEF14.Art technology
Personnel are by reference to the description as described in PCC parts in each versions of 3GPP, you can to understand above-mentioned each interface
Specific definition, therefore for succinct, the definition of above-mentioned each interface is no longer described in detail herein.
Wherein, in actual applications, above-mentioned each logical functional entity can be deployed in another hardware device,
Multiple logical functional entities can be deployed in same hardware device, or and not all logic function reality
Body is required.For example, PCEF is generally positioned in the GW (Gate-Way, gateway) 19 of network,
Such as the GGSN (Gateway GPRS Support Node, GPRS gateway support node) in GPRS
And the PDG (Packet Data Gateway, packet data gateway) in I-WLAN.In another example TDF
It can determine whether to dispose as requested.In another example OCS and OFCS can only dispose one of them.
Wherein, AF12 is the access point for providing service application, and network used in these service applications provides
Source needs to carry out dynamic policy control.When service surface carries out parameter negotiation, AF12 is by related service
Information transmission is to PCRF13, if these business information are tactful consistent with PCRF13,
PCRF13 receives the negotiation；Otherwise, PCRF13 refuses the negotiation, and provides simultaneously in feedback
The acceptable service parameters of PCRF13.Then, AF12 can return to these parameters UE (User
Equipment, user equipment).
Wherein, PCRF13 is PCC core, is responsible for strategic decision-making and the formulation of charging regulation.
PCRF13 provides the network control rule based on business data flow, and the control of these networks includes business number
According to the monitoring of stream, gate (Gating Control), QoS (Quality of Service, service quality) controls
And charging regulation based on data flow etc..The strategy and charging regulation that PCRF13 is formulated are sent to
PCEF14 is performed, meanwhile, PCRF13 also needs to ensure that these rules are consistent with the signing information of user.
PCRF13 generates strategy to be included but is not limited to the foundation of charging regulation：Obtained from AF12 and business
Related information, the user policy, billing control and subscription information obtained from SPR11, and from PCEF14
The information of the network related to carrying obtained.
Wherein, PCEF14 is used for the strategy and charging regulation formulated in loading end execution PCRF13.
PCEF14 flows into according to the business datum flow filter in the rule transmitted by PCRF13 to business datum
Row monitoring, and then these business data flows are performed with the strategy and charging regulation that PCRF13 is formulated.
When carrying is established, the rule that PCEF14 is sent according to PCRF13 carries out QoS mandates, and according to AF12
Execution carry out gate control.The charging regulation sent according to PCRF13, PCEF14 perform corresponding
Service data flow charge operates.Wherein, charging can be online charging or offline charging.Such as
Fruit is online charging, then PCEF14 needs and OCS16 carries out credit management together.If offline meter
Take, then exchange correlation charge information between PCEF14 and OFCS17.
Wherein, BBERF18 function includes bearing binding, the checking of up bearing binding and event
Report.When UE is accessed by E-UTRAN, and PMIPv6 is used between S-GW and P-GW
During agreement, BBERF18 is located in S-GW.When UE is accessed by trusted non-3 GPP access system
When, BBERF18 is located at trusted non-3 GPP access gateway, when UE passes through trustless non-3 gpp
Access system access when, BBERF18 be located at ePDG (Evolved Packet Data Gateway, evolution
Packet data gateway).Now, PCEF13 no longer performs bearing binding function.
Wherein, TDF15 is responsible for performing the business detection of data flow.It is by the application detected and its data
Stream description reports PCRF13.ADCs of the TDF15 according to PCRF13 activation
(Application Detection and Control, regular using being monitored and controlled) or pre-configured rule
The beginning and end of application is detected, and PCRF13 is notified at the beginning and end of application.TDF15 is simultaneously
It is also responsible for the functions such as gate, redirection, bandwidth limitation and the charging of Business Stream.SPR (user contracting datas
Storehouse) 11 store the user policy, billing control and subscription information related to charging to policy control.SPR11
Interface between PCRF13 is Sp interfaces.Under the scene using UDR, SPR1 network elements and Sp
Interface is substituted by UDR network elements and Ud interfaces.
Wherein, OCS16 carries out the control of user credit and pipe under online charging mode together with PCEF
Reason, can be controlled and managed to user credit by Gyn interfaces in the case where disposing TDF15.
And policy counter state is passed to by PCRF13 by Sy interfaces.
Wherein, OFCS17 completes the billing operation under offline charging mode together with PCEF14, in portion
Also cooperateed with the case of administration TDF15 with TDF15 and complete offline charging function.
It is one PDN of access that PCC frameworks shown in Fig. 1 are realized to UE by each functional entity
IP-CAN (the IP Connectivity that (Packet Data Network, packet data network) is established
Access Network, IP connections access network) session strategy and charging control.
In the framework shown in Fig. 1, two kinds of policy control modes based on dosage are supported.One of which
It is by carrying out dosage collection based on Gx and Sd interfaces, i.e., by PCRF13 according to being based on Gx and Sd interfaces
The dosage and other information (such as dosage thresholding) collected carries out strategic decision-making.Another kind is to be based on Gy
And Gyn interfaces carry out dosage collection：I.e. by OCS16 according to being collected based on Gy and Gyn interfaces
Information carries out dosage statistics, and the parameter that dosage and OCS of the OCS16 based on statistics are pre-set is sentenced
The dosage state of disconnected user, the policy counter status information related to dosage of user is connect by Sy
Mouth notice PCRF13 carries out strategic decision-making.Wherein, there is no Sd and Gyn when not disposing TDF network elements
Interface.
In view of in framework shown in Fig. 1, if the dosage of PCC policy controls is entered based on Gx/Sd interfaces
Row collection, now OCS also can gather information by Gy/Gyn interfaces and carry out charging, therefore be based on Gx/Sd
The collection that interface is carried out can have the consistency problem that information is gathered with the Gy/Gyn interfaces of charging.This can
The additional workload of later maintenance can be introduced.Therefore, can unify to use billing interface (such as Gy/Gyn
Interface) dosage of collection carries out policy control.In the 3GPP agreements, it has been specified that PCRF13
Sy interfaces between OCS16.The interface is used for OCS16 to PCRF13 transmission policy counter shapes
State information.And the dosage of Gy and Gyn interfaces collection is the important of OCS16 assessment strategy counter status
One of information source.
In actual applications, after not supporting that Sy interfaces and OCS are not responsible due to the OCS of part producer
Paid service, it can be considered to separate a part and dosage policy-related (noun) function from OCS.
The functional network element separated uniformly is responsible for the pre-payment dosage statistics related to the PCC of postpaid service user.
As shown in Fig. 2 it is the PCC controls system for the post payment service that dosage collection is carried out based on Gy interfaces
The Organization Chart of system.As shown in Fig. 2 also carry out Gy Interface Controllers for postpaid service user, now Gy
Interface is simultaneously not connected to OCS, but connects dosage monitoring device 20.Dosage monitoring device 20 and PCRF13
Between use Sy interfaces.Dosage monitoring device 20 can also accept report form statistics and/or data analysis, with
And application function derived from the dosage monitoring such as user's notice.But for prepayment service, due to PCEF
Do not support to export Gy and Gyn to OCS and dosage monitoring device simultaneously to same data session with TDF
The problem of interface.I.e.：PCEF is not supported for same data session while is supported two Gy interface controls
System；TDF is not supported for same data session yet while is supported two Gyn Interface Controllers.This just makes
Into independent dosage monitoring device can not be disposed for prepayment service.
In view of this, as shown in figure 3, being the strategy of the present invention and the reality of charging control (PCC) system
Apply the configuration diagram of example.Wherein, Fig. 3 and Fig. 1 main distinction is, in Accounting Client (such as
PCEF14 and TDF15) dosage monitoring device 20 is introduced between OCS16.Wherein, dosage monitors
Gy interfaces are used between device 20 and PCEF14, Gyn interfaces are used between TDF15, with PCRF13
Between use Sy interfaces, Gy and Gyn interfaces are used between OCS16.Wherein, when in the absence of TDF15
When, then Gyn interfaces are correspondingly not present.Wherein, the dosage monitoring device 20 can carry out dosage and add up
Judge with dosage corresponding strategies counter status.For example, adopted between dosage monitoring device 20 and PCRF13
Dosage corresponding strategies counter status is interacted with Sy interfaces, wherein Sy interfaces, which can refer in 3GPP, closes
In the definition of Sy interfaces, and dosage state is with reference to the definition in 3GPP on Sy interface strategies counters.
Wherein, dosage monitoring device 20 can carry out the real time billing between PCEF14/TDF15 and OCS16
The transmission of message, the wherein Real-time charging messages can include：Real-time meter from PCEF14/TDF15
Take request and the real time billing response from OCS16, etc..Therefore, dosage monitoring device 20 can be
PCEF (or TDF) transmits Real-time charging messages between OCS, and carries out dosage monitoring, and with
PCRF interacts dosage corresponding strategies counter status, without requiring PCEF (or TDF) supports pair
Two Gy interfaces (or Gyn interfaces) controls are supported simultaneously in same data session, so as to prop up
Hold the independent dosage monitoring to prepayment service.To the tactful of the present invention and counted below based on Fig. 3 framework
Expense control method illustrates, it is to be understood that this method can depart from Fig. 3 framework and exist.
As shown in figure 4, it is the strategy and the schematic flow sheet of the embodiment of billing control method of the present invention.
It includes：
Step 41：Dosage monitoring device is in network element (such as PCEF or TDF) between Online Charging System

Step 42：Dosage monitoring device gathers the dosage traffic contained in the real time billing request, to enter
Row dosage monitors.
Wherein, the network element in step 41 can be foregoing PCEF 14 or TDF15.Wherein, should
Real-time charging messages are such as being related to real time billing request and real time billing response.Wherein, step 31 is main
For transmitting Real-time charging messages.
Wherein, in step 42, the dosage letter contained in dosage monitoring device collection real time billing request
Amount can be included with carrying out the operation of dosage monitoring：Dosage monitoring device adds up the history dosage of user, and
The dosage state of user, and the plan related to PCRF interaction transmission dosages are judged according to the history dosage
Slightly counter and its status information.Wherein, step 42 is mainly used in dosage monitoring.
Illustrate the present invention's from two angles of transmission of dosage monitoring and Real-time charging messages separately below
