In the present embodiment, after OCS receives the reservation credit line request of TDF entity transmission, can acquire this first rate group and this second rate group of reserving in the credit line request, then OCS can set up the incidence relation of the first rate group and the second rate group.

OCS also calculates the mandate business unit, and namely OCS also calculates the first mandate business unit corresponding to the first rate group according to this first rate batch total, and calculates the second mandate business unit corresponding to the second rate group according to this second rate batch total.Particularly, OCS can calculate the first mandate business unit according to the first rate group and user account remaining sum, and can calculate the second mandate business unit according to the second rate group and user account remaining sum.For example: rate corresponding to the first rate group is 1 yuan/M and rate corresponding to the second rate group is 2 yuan/M, user account remaining sum is 300 yuan, then the first rate group of calculating of OCS corresponding first authorize business unit be 300 yuan/(1 yuan/M)=300M, OCS calculate the second rate group corresponding second authorize business unit be 300 yuan/(2 yuan/M)=150M.Then OCS execution in step 409 and more above-mentioned the first mandate business unit and second that calculates are authorized the size of business unit, if first authorizes business unit to authorize business unit greater than second, then also need execution in step 411 after the OCS execution in step 410, authorize business unit if first authorizes business unit to be not more than second, then OCS does not need execution in step 411, i.e. execution in step 412 after the execution in step 410.

Step 410, OCS send to the TDF entity and reserve the credit line response.

In the present embodiment, after OCS calculates the second mandate business unit corresponding to this second rate group, then OCS sends to the TDF entity and reserves the credit line response, carries mandate business unit corresponding to this second rate group (being 150M) in this reservation credit line response.

Step 411, OCS send to the PCEF entity and reserve the credit line updating message.

In the present embodiment, when first authorizes business unit to authorize business unit greater than second, need this moment the PCEF entity to upgrade mandate business unit corresponding to the first rate group of reserving, if do not upgrade, can exist the business of the data flow of PCEF entity place carrying application to use the unit to surpass the phenomenon of mandate business unit corresponding to this application, thereby cause the user to exceed the quata to use; Therefore, OCS sends to the PCEF entity and reserves the credit line updating message, carries second in this reservation credit line updating message and authorizes business unit (being 150M), is updated to second with the mandate business unit that will reserve on the PCEF entity and authorizes business unit.After the PCEF entity received this reservation credit line updating message, the mandate business unit 300M that the first rate group of obtaining in the step 402 is corresponding was updated to 150M, exceeded the quata to use to avoid the user.

Step 412, TDF entity send data flow to the server of using.

The TDF entity receives this reservation credit line response that OCS sends, after getting access to mandate business unit corresponding to the second rate group, then the TDF entity can authorize business unit to use the unit to add up to the business of the data flow of carrying this application according to this, uses the unit to surpass this mandate business unit in order to avoid carry the business of the data flow of this application.Then the TDF entity sends to the server of application corresponding to this application with data flow, need to prove that the server of this application is not shown in Figure 4.

Step 413, TDF entity detection are used and are finished.

In the present embodiment, the TDF entity detection one of ordinary skill in the art will appreciate that to use finishing, and the TDF entity detection is used in the process that finishes and the prior art consistent, and the present invention is not described in detail at this.

Step 414, TDF entity send to OCS and stop credit control request information.

In the present embodiment, after the TDF entity detection was used end to this, the TDF entity can be added up the business of the data flow that obtains this application of carrying and use unit (the business use unit of namely using).The TDF entity sends to OCS and stops credit control request information, carries the business of this application in this termination credit control request information and uses unit and this second rate group.

Step 415, OCS send the re-authorization request message to the PCEF entity.

In the present embodiment, OCS receives this termination credit control request information that the TDF entity sends after detecting the application end, obtain the business of this application that this termination credit control request information carries and use unit and the second rate group, then OCS obtains the first rate group of this second rate group association according to the first rate group of setting up in the step 409 and the incidence relation of the second rate group.Then OCS sends the re-authorization request message to the PCEF entity, carries the first rate group in this re-authorization request message.

Step 416, PCEF entity send to OCS and upgrade credit control request information.

In the present embodiment, the PCEF entity receives the re-authorization request message that OCS sends, get access to the first rate group of carrying in this re-authorization request message, use the unit according to the business that this first rate group statistics obtains data flow corresponding to the first rate group, then the PCEF entity sends to OCS and upgrades credit control request information, carries business corresponding to this first rate group in this renewal credit control request information and uses the unit.

Step 417, OCS reduce user account, recomputate the mandate business unit.

In the present embodiment, be combined with the second rate group and carry out the charging processing in the business use unit that OCS will use, because business corresponding to this first rate group uses the unit to comprise the business use unit of this application, so OCS also business that this first rate group is corresponding uses the business of unit and this application to use difference and the first rate group of unit, thus the reducing of realization user account.Namely, the business of using is used the product of the unit rate corresponding with the second rate group, the sum of products that the business corresponding with data flow used rate corresponding to difference that the business of unit and this application uses the unit and the first rate group is as this use volume of user, then from user account, deduct this use volume of user, wherein, the business of data flow uses the business of unit and this application to use the difference of unit also can be zero.For example: OCS receives the business of the application of TDF entity transmission and uses the unit to be 70M, business corresponding to the first rate group that receives the transmission of PCEF entity uses the unit to be 90M, then use the volume that uses of unit to be 70M * 2 yuan/M=140 unit for the business of this application, and use use volume that the business corresponding to data flow of not carrying this application in the unit use the unit to be (90M-70M) * 1 yuan/M=20 unit for business corresponding to the first rate group, thereby OCS is 140 yuan+20 yuan=160 yuan to the capable concrete volume of reducing of user account.

Because 300 yuan of the remaining sums of user account before using beginning, use finish after OCS user account has been carried out 160 yuan reducing, then use and finish afterwards that the remaining sum of user account is 140 yuan.Because the remaining sum of user account is upgraded, so mandate business unit corresponding to the first rate group of storing in the PCEF entity also should upgrade, exceed the quata to use to avoid the user.So OCS recomputates the mandate business unit according to remaining sum and the first rate group of user account after upgrading, and the mandate business unit that will recomputate sends to the PCEF entity.Particularly, OCS recomputates and authorizes business unit to be: 140 yuan/(1 yuan/M)=140M.

Alternatively, OCS deletes the incidence relation of the first rate group and the second rate group.In the present embodiment, OCS receives in the renewal credit control request information of PCEF entity transmission, and after getting access to business corresponding to the first rate group of upgrading in the credit control request information and using the unit, finish owing to use, then OCS deletes the incidence relation of the first rate group and the second rate group, in order to avoid the foundation of the incidence relation in the next charging process of using of impact.

Step 418, OCS send to the PCEF entity and upgrade Credit Control Answer message.

In the present embodiment, OCS sends renewal Credit Control Answer message to the PCEF entity after obtaining the mandate business unit that recomputates, and carries this mandate business unit that recomputates (being 140M) in this renewal control response message.

The charging method that the embodiment of the invention four provides, application by TDF entity detection data flow coupling, and the PCRF entity sends application start message, the PCRF entity is determined the first rate group and the second rate group according to this application start message, and send to the TDF entity by use detecting control law, the TDF entity sends the credit line request of reserving to OCS, OCS sets up the incidence relation of the first rate group and the second rate group, and calculate the first rate group corresponding first authorize business unit and the second rate group corresponding second authorize business unit, send mandate business unit corresponding to the second rate group by reserving the credit line response to the TDF entity, when first authorizes business unit to authorize business unit greater than second, the second mandate business unit is sent to the PCEF entity by reserving the credit line updating message, authorize business unit so that the mandate business unit of reserving on the PCEF entity is updated to second; When the TDF entity detection finishes to application, use the unit to send to OCS by stopping credit control request information the business of the second rate group and application to OCS, OCS obtains the first rate group of the second rate group association, and the first rate group sent to the PCEF entity by the re-authorization request message, then receive the business use unit corresponding with this first rate group that the PCEF entity sends, and the business that will use is used the product of the unit rate corresponding with the second rate group, the business corresponding with data flow uses the sum of products of rate corresponding to difference that the business of unit and application uses the unit and the first rate group as user's use volume, user account is reduced, remaining sum and the first rate group according to user account recomputates the mandate business unit at last, and this mandate business unit that recomputates is sent to the PCEF entity.Thereby solved the problem that repeats charging, further, the phenomenon of also having avoided the user to exceed the quata to use.

Optionally, in the embodiment shown in fig. 4, be a kind of as example take the TDF entity detection to the application with the data flow coupling.Optionally, the TDF entity detection also can be two or more to the application with the data flow coupling.If the TDF entity detection has two or more to the application with the data flow coupling in the step 404, in the so follow-up step, when processing application related information, then need to process two or more application message.Here repeat no more.

Fig. 5 is the flow chart of charging method embodiment five of the present invention, and present embodiment is to before the present invention's step 413 embodiment illustrated in fig. 4, and the PCEF entity knows that the processing procedure when the mandate business unit of reservation is finished using is introduced.

As shown in Figure 5, this charging method can comprise:

Step 501, PCEF entity know that the mandate business unit of reservation finishes using.

In the present embodiment, when data stream transmitting during to the PCEF entity, the PCEF entity can be added up business corresponding to the first rate group and use the unit, when business corresponding to this first rate group uses the unit to equal mandate business unit corresponding to the first rate group that the PCEF entity obtains from OCS, then the mandate business unit of explanation reservation is finished using, for example: rate corresponding to the first rate group is 1 yuan/M, the mandate business unit of reserving is 150M, and then mandate business unit corresponding to the first rate group this moment is 150M.

Step 502, PCEF entity send to OCS and upgrade credit control request information.

In the present embodiment, after the PCEF entity knows that the mandate business unit of reservation is finished using, send the renewal credit control request information to OCS, business corresponding to the first rate group and the first rate group that carry in this renewal credit control request information used unit (being 150M).

Step 503, OCS send the re-authorization request message to the TDF entity.

In the present embodiment, OCS receives the renewal credit control request information that the PCEF entity sends after the mandate business unit that the PCEF entity is reserved is finished using, obtain the first rate group and business corresponding to the first rate group upgraded in the credit control request information and use the unit.According to the incidence relation of this first rate group and the second rate group, obtain the second rate group of the first rate group association, then OCS sends the re-authorization request message to the TDF entity, carries the second rate group in this re-authorization request message.

Step 504, TDF entity send to OCS and upgrade credit control request information.

In the present embodiment, the TDF entity receives the re-authorization request message that OCS sends, get access to the second rate group of carrying in this re-authorization request message, obtain the employed professional unit that uses of application corresponding to the second rate group according to this second rate group statistics, for example: use employed business and use the unit to be 50M, then the TDF entity sends to OCS and upgrades credit control request information, carries the employed professional unit (being 50M) that uses of application corresponding to this second rate group in this renewal credit control request information.

Step 505, OCS reduce user account, recomputate the mandate business unit.

In the present embodiment, OCS uses unit and business corresponding to this first rate group to use the unit according to the business of this application, and user account is reduced.Particularly, be combined with the second rate group and carry out the charging processing in the business use unit that OCS will use, because business corresponding to this first rate group uses the unit to comprise the business use unit of this application, so OCS also business that this first rate group is corresponding uses the business of unit and this application to use the difference of unit be combined with the first rate group to carry out the charging processing, thus the reducing of realization user account.Namely, the business of using is used the product of the unit rate corresponding with the second rate group, the sum of products that the business corresponding with data flow used rate corresponding to difference that the business of unit and this application uses the unit and the first rate group is as this use volume of user, then from user account, deduct this use volume of user, wherein, the business of data flow uses the business of unit and this application to use the difference of unit also can be zero.For example: OCS receives the business of the application of TDF entity transmission and uses the unit to be 50M, business corresponding to the first rate group that receives the transmission of PCEF entity uses the unit to be 150M, then use the volume that uses of unit to be 50M * 2 yuan/M=100 unit for the business of this application, and use use volume that the business corresponding to data flow of not carrying this application in the unit use the unit to be (150M-50M) * 1 yuan/M=100 unit for business corresponding to the first rate group, thereby OCS is 100 yuan+100 yuan=200 yuan to the capable concrete volume of reducing of user account.

Because 300 yuan of the remaining sums of user account before using beginning, know that at PCEF OCS has carried out 200 yuan reducing to user account after the mandate business unit of reservation is finished using, then the remaining sum of user account is 100 yuan at this moment.Because the remaining sum of user account is upgraded, so mandate business unit corresponding to the second rate group of reserving in the mandate business unit that the first rate group of reserving in the PCEF entity is corresponding and the TDF entity also should upgrade, so that the user can continue to use this application to avoid simultaneously the user to exceed the quata to use.So OCS recomputates the first mandate business unit according to remaining sum and the first rate group of the rear user account of renewal, and recomputate the second mandate business unit according to remaining sum and the second rate group of user account after upgrading.For example: rate corresponding to the first rate group is that 1 yuan/M, rate corresponding to the second rate group are 2 yuan/M, the new balance of user account is 100 yuan, then OCS recomputates first and authorizes business unit to be: 100 yuan/(1 yuan/M)=and 100M, OCS recomputates second and authorizes business unit to be: 100 yuan/(2 yuan/M)=50M.

Step 506, OCS send to the TDF entity and upgrade Credit Control Answer message.

In the present embodiment, OCS is after obtaining the second mandate business unit that recomputates corresponding to the second rate group, send renewal Credit Control Answer message to the TDF entity, carry the second mandate business unit (being 50M) that this recomputates in this renewal control response message.Correspondingly, the TDF entity receives this renewal Credit Control Answer message, obtain the second rate group of carrying in this renewal Credit Control Answer message corresponding recomputate second authorize business unit, and the mandate business unit that will reserve be updated to recomputate second authorize business unit, for example: the TDF entity is updated to 50M with 150M.

Step 507, OCS send to the PCEF entity and upgrade Credit Control Answer message.

In the present embodiment, OCS is after obtaining the first mandate business unit that recomputates corresponding to the first rate group, the the first mandate business unit that relatively recomputates first and the size of the second mandate business unit that recomputates, with recomputate first authorize business unit and recomputate second authorize smaller value in the business unit to be carried to upgrade in the Credit Control Answer message to send to the PCEF entity, carry the second mandate business unit (being 50M) that this recomputates in this renewal control response message, correspondingly, the PCEF entity receives this renewal Credit Control Answer message, the the second mandate business unit that recomputates that obtains to carry in this renewal Credit Control Answer message, and the mandate business unit that will reserve is updated to the second mandate business unit that recomputates, for example: the PCEF entity is updated to 50M with 150M, exceeds the quata to use to avoid the user.

Further, after execution of step 507, the PCEF entity uses the unit to add up to the business of data flow again, the TDF entity uses the unit to add up to the business of this application again, until using to this, the TDF entity detection finishes, the TDF entity obtains the business of the again application of statistics and uses the unit, and the TDF entity sends to OCS and stops credit control request information, carries the business of again this application of statistics in this termination credit control request and uses unit and the second rate group.After OCS receives this termination credit control request information, obtain the business that stops this application in the credit control request information and use unit and the second rate group, incidence relation according to the first rate group and the second rate group, obtain again the business of data flow corresponding to the first rate group of statistics to the PCEF entity and use the unit, then the business that will use of OCS is used the unit to be combined with the second rate group to carry out the charging processing, because the business of this data flow use unit has comprised the business of this application and has used the unit, carried out the charging processing so OCS uses the business of unit and this application to use the difference of unit to be combined with the first rate group the business of this data flow again.Detailed process sees also the description of the present invention's middle step 413 embodiment illustrated in fig. 4 ~ step 418, does not repeat them here.

The charging method that the embodiment of the invention five provides further, receives the renewal credit control request information that the PCEF entity sends by OCS, and sends the re-authorization request message to the TDF entity after the mandate business unit that the PCEF entity is reserved is finished using; The TDF entity receives the re-authorization request message that OCS sends, and sends the renewal credit control request information to OCS; OCS receives the renewal credit control request information that the TDF entity sends, and according to the employed professional unit that uses of application corresponding to the second rate group user account is reduced, then remaining sum and the first rate group according to user account recomputates the first mandate business unit, and recomputate second according to the remaining sum of user account and the second rate group and authorize business unit, what OCS will recomputate second authorizes business unit to be carried to upgrade in the Credit Control Answer message and sends to the TDF entity, and will recomputate first authorize business unit and recomputate second authorize smaller value in the business unit to be carried to upgrade in the Credit Control Answer message to send to the PCEF entity.Thereby solved the problem that repeats charging, further, the phenomenon of also having avoided the user to exceed the quata to use.

Fig. 6 is the flow chart of charging method embodiment six of the present invention, and present embodiment is to before the present invention's step 413 embodiment illustrated in fig. 4, and the processing procedure when the PCEF entity detection changes to charge information is introduced.

As shown in Figure 6, this charging method can comprise:

Step 601, PCEF entity detection change to charge information.

In the present embodiment, when the PCEF entity will detect charge information and changes, charge information can affect rate corresponding to rate group, and wherein, this charge information can be position, APN (the Access Point Name at user place; Be designated hereinafter simply as APN) etc., one of ordinary skill in the art will appreciate that charge information affects in rate corresponding to rate group and the prior art consistent, the present invention is not described in detail at this.Then need OCS elder generation to carry out the charging processing according to the charge information before changing and rate group, and then carry out the charging processing according to the charge information after changing and rate group.

Business corresponding to the first rate group that the PCEF entity can be added up before charge information changes used the unit, and for example: rate corresponding to the first rate group before charge information changes is 1 yuan/M, and business corresponding to the first rate group uses the unit to be 90M.

Step 602, PCEF entity send to OCS and upgrade credit control request information.

In the present embodiment, after the PCEF entity detection changes to charge information, send to upgrade credit control request information to OCS, carry business use unit (being 90M) corresponding to charge information, the first rate group and the first rate group after the variation in this renewals credit control request information.

Step 603, OCS send the re-authorization request message to the TDF entity.

In the present embodiment, OCS receives the renewal credit control request information that the PCEF entity sends after the PCEF entity detection changes to charge information, obtain business use unit corresponding to charge information, the first rate group and the first rate group after the variation in the renewal credit control request information.According to the incidence relation of this first rate group and the second rate group, obtain the second rate group of the first rate group association, then OCS sends the re-authorization request message to the TDF entity, carries the second rate group in this re-authorization request message.

Step 604, TDF entity send to OCS and upgrade credit control request information.

In the present embodiment, the TDF entity receives the re-authorization request message that OCS sends, get access to the second rate group of carrying in this re-authorization request message, obtain the employed professional unit that uses of application corresponding to the second rate group according to this second rate group statistics, for example: use employed business and use the unit to be 70M, then the TDF entity sends to OCS and upgrades credit control request information, carries the employed professional unit (being 70M) that uses of application corresponding to this second rate group in this renewal credit control request information.

Step 605, OCS reduce user account, recomputate the mandate business unit.

In the present embodiment, OCS uses unit and business corresponding to this first rate group to use the unit according to the business of this application, and user account is reduced.Particularly, be combined with the second rate group and carry out the charging processing in the business use unit that OCS will use, because business corresponding to this first rate group uses the unit to comprise the business use unit of this application, so OCS also business that this first rate group is corresponding uses the business of unit and this application to use the difference of unit be combined with the first rate group to carry out the charging processing, thus the reducing of realization user account.Namely, the business of using is used the product of the unit rate corresponding with the second rate group, the sum of products that the business corresponding with data flow used rate corresponding to difference that the business of unit and this application uses the unit and the first rate group is as this use volume of user, then from user account, deduct this use volume of user, wherein, the business of data flow uses the business of unit and this application to use the difference of unit also can be zero.For example: OCS receives the business of the application of TDF entity transmission and uses the unit to be 70M, business corresponding to the first rate group that receives the transmission of PCEF entity uses the unit to be 90M, then use the volume that uses of unit to be 70M * 2 yuan/M=140 unit for the business of this application, and use use volume that the business corresponding to data flow of not carrying this application in the unit use the unit to be (90M-70M) * 1 yuan/M=20 unit for business corresponding to the first rate group, thereby OCS is 140 yuan+20 yuan=160 yuan to the capable concrete volume of reducing of user account.

Because 300 yuan of the remaining sums of user account before using beginning, PCEF detect charge information change after OCS user account has been carried out 160 yuan reducing, then the remaining sum of user account is 140 yuan at this moment.Because the remaining sum of user account is upgraded, and variation has also occured in charge information, so mandate business unit corresponding to the second rate group of reserving in the mandate business unit that the first rate group of reserving in the PCEF entity is corresponding and the TDF entity also should upgrade, so that the user can continue to use this application to avoid simultaneously the user to exceed the quata to use.So charge information and the first rate group of OCS according to the remaining sum of user account after upgrading, after changing recomputates first and authorize business unit, and the charge information according to the remaining sum of user account after upgrading, after changing and the second rate group recomputate second and authorize business unit.For example: rate corresponding to the first rate group was that rate corresponding to the second rate group was 4 yuan/M after 2 yuan/M, charge information changed after charge information changed, the remaining sum of user account is 140 yuan after upgrading, then OCS recomputates first and authorizes business unit to be: 140 yuan/(2 yuan/M)=and 70M, OCS recomputates second and authorizes business unit to be: 140 yuan/(4 yuan/M)=35M.

Step 606, OCS send to the TDF entity and upgrade Credit Control Answer message.

In the present embodiment, OCS is after obtaining the second mandate business unit that recomputates corresponding to rear the second rate group of charge information variation, send renewal Credit Control Answer message to the TDF entity, carry the second mandate business unit (being 35M) that this recomputates in this renewal control response message.Correspondingly, the TDF entity receives this renewal Credit Control Answer message, obtain the second rate group of carrying in this renewal Credit Control Answer message corresponding recomputate second authorize business unit, and the mandate business unit that will reserve be updated to recomputate second authorize business unit, for example: the TDF entity is updated to 35M with 150M.

Step 607, OCS send to the PCEF entity and upgrade Credit Control Answer message.

In the present embodiment, OCS is after obtaining the first mandate business unit that recomputates corresponding to rear the first rate group of charge information variation, the the first mandate business unit that relatively recomputates first and the size of the second mandate business unit that recomputates, with recomputate first authorize business unit and recomputate second authorize smaller value in the business unit to be carried to upgrade in the Credit Control Answer message to send to the PCEF entity, carry the second mandate business unit that this recomputates in this renewal control response message, be 35M, correspondingly, the PCEF entity receives this renewal Credit Control Answer message, the the second mandate business unit that recomputates that obtains to carry in this renewal Credit Control Answer message, and the mandate business unit that will reserve is updated to the second mandate business unit that recomputates, for example: the PCEF entity is updated to 35M with 150M, exceeds the quata to use to avoid the user.

Further, after execution of step 607, the PCEF entity uses the unit to add up to the business of data flow again, the TDF entity uses the unit to add up to the business of this application again, until using to this, the TDF entity detection finishes, the TDF entity obtains the business of the data flow of this application of carrying and uses unit (business of namely using is used the unit), the TDF entity sends to OCS and stops credit control request information, carries the business of again this application of statistics in this termination credit control request and uses unit and the second rate group.After OCS receives this termination credit control request information, obtain the business that stops this application in the credit control request information and use unit and the second rate group, incidence relation according to the first rate group and the second rate group, obtain again the business of data flow corresponding to the first rate group of statistics to the PCEF entity and use the unit, then OCS uses unit and the second rate group according to the business of this application, the business of the data flow that obtains from PCEF is used unit and the first rate group and new charge information to carry out charging and is processed, particularly, business that OCS will use is used unit and the second rate group and new charge information to be combined to carry out the charging processing, because the business of this data flow uses the unit to comprise that the business of this applications uses the unit, so using the business of this data flow difference and the first rate group of business use unit of unit and this application and new charge information to be combined, OCS carries out again the charging processing.Detailed process sees also the description of the present invention's middle step 413 embodiment illustrated in fig. 4 ~ step 418, does not repeat them here.

The charging method that the embodiment of the invention six provides further, receives the renewal credit control request information that the PCEF entity sends by OCS, and sends the re-authorization request message to the TDF entity after the PCEF entity detection changes to charge information; The TDF entity receives the re-authorization request message that OCS sends, and sends the renewal credit control request information to OCS; OCS receives the renewal credit control request information that the TDF entity sends, and use the unit that user account is reduced according to employed professional unit and business corresponding to the first rate group used of application corresponding to the second rate group, then according to the remaining sum of user account, charge information after the variation and the first rate group recomputate first and authorize business unit, and according to the remaining sum of user account, charge information after the variation and the second rate group recomputate second and authorize business unit, what OCS will recomputate second authorizes business unit to be carried to upgrade in the Credit Control Answer message and sends to the TDF entity, and will recomputate first authorize business unit and recomputate second authorize smaller value in the business unit to be carried to upgrade in the Credit Control Answer message to send to the PCEF entity.Thereby solved the problem that repeats charging, further, the phenomenon of also having avoided the user to exceed the quata to use.

Need to prove, the business of rate corresponding to corresponding rate, the second rate group of cited the first rate group, user account remaining sum, application uses unit and business corresponding to the first rate group to use each numerical value of unit in the various embodiments described above of the present invention, all be in order to be illustrated, the present invention is not as limit.

Fig. 7 is the structural representation of TDF physical embodiment one of the present invention, and as shown in Figure 7, the TDF entity of present embodiment can comprise: receiver module 11, detection module 12 and sending module 13, and wherein, receiver module 11 is used for receiving the data flow that the PCEF entity sends; And after sending module 13 sends application start message to the PCRF entity, receive the application detection control law that the PCRF entity sends, use the detection control law and carry the first rate group corresponding to data flow and the second rate group corresponding with the application of data flow coupling.Detection module 12 is for detection of the application of the data flow coupling that obtains to receive with receiver module 11.Sending module 13 is used for sending application start message to the PCRF entity, carry information detection module 12 acquisitions and the application data flow coupling in the application start message, and the IP five-tuple of data flow, so that the PCRF entity is used the second corresponding rate group according to the first rate group corresponding to IP five-tuple matched data stream according to the information matches of using; And after the detection control law is used in receiver module 11 receptions, send the credit line request of reserving to OCS, comprise the first rate group and the second rate group in the request of reservation credit line; So that OCS sets up the incidence relation of the first rate group and the second rate group; And after detection module 12 detects the application end, send the termination credit control request information to OCS, stop carrying in the credit control request information business use unit and the second rate group of application, so that OCS uses the business of described application the product of the unit rate corresponding with described the second rate group, the business corresponding with described data flow uses the sum of products of rate corresponding to difference that the business of unit and described application uses the unit and described the first rate group as user's use volume, deducts described user's use volume from user account.

The description of interaction flow between above-mentioned each module in specifically can reference method embodiment repeats no more here.
