Description
Technical field
The present invention relates to the method and apparatus of allocated quotas in online charging system more particularly to online charging system.
Background technique
Online charging system (Online Charging System, OCS) provides such a mechanism: charge information warp
By the real-time service access of direct reciprocal effect of the control with Internet usage.That is, the mirror of Internet usage
Power must be obtained before real resource is using generation by network.Further, since the authentication that resource uses may be within its scope
(for example, data volume or duration) is limited, and therefore, as long as the Internet usage of user continues, authentication needs frequently
Ground updates.
The billing mechanism provides following benefit: ensuring Internet resources before real resource use.But the mechanism
May also lead to the delay of business, if the authentication due to online charging functional entity (Online Charging Function,
OCF) side occur mistake and fail obtain Internet resources, then the business of terminal user will be delayed by or prevent.This is to prepayment
Take subscriber and brings very bad end-user experience using monitor/track/control post-paid subscriber with real-time.
For post-paid subscriber, which also brings such worry: network operator whether have the ability simultaneously by pre-payment and
Post-paid is fused in online payment mode.
Currently, in the side OCF or in the side charging triggering function entity (Charging Trigger Function, CTF),
Assuming that successful solution (Assume Positive Solution, APS) is widely used.In APS, introduces and assume successfully mould
Block (Assume Positive Module, APM), the module be used to detect the state of OCF and when the authentication of OCF can not obtain
When obtaining, fixed quota (Quota) is distributed.
The program is simultaneously not perfect, because each allocated quota of APM is fixed.Charging due to lacking subscriber is believed
Breath, fixed hypothesis success quota (Fixed Assume Positive Quota, FAPQ) may cause the control target of OCF
It is uncontrollable.
For example, by applying FAPQ, then may when the control target of OCF is that no excess spends (Over Charge)
Excess is generated to spend.For example, if the available amount of subscriber is enough for 2M, but FAPQ is 4M, then, 2M will be generated
Excess spend.At this point, a large amount of bill volumes can be generated if the charge rate that uses of excess is higher.
In another example when the control target of OCF is to pass through application in exact notice threshold point triggering usage amount notice
FAPQ then has very high possibility to cannot achieve the target.For example, user wishes to reach usage amount limit in usage amount
It is notified when 100%.It is assumed that current usage amount is the 98% of usage amount limit, then assume that successful solution, FAPQ are (false
It is set to the 8% of usage amount limit) it is distributed by APM.After quota is depleted, subscriber can receive notice, and at that time,
Usage amount alreadys exceed the 6% of usage amount limit.
Summary of the invention
In APS, when data service starts, OCF is the traffic assignments quota.If the authentication of OCF is unavailable,
Then APM is with fixed quota size for traffic assignments FAPQ, and then the business continues to run.Fig. 1 shows to apply and be based on
An example of FAPQ in the data session of DIAMETER agreement.In this example embodiment, when OCF allocated quotas, subscriber's
Alert notification thresholding is considered.
OCF allocated quota Quota=Min (NAT-RU, Maximum Quota).Wherein, NAT table shows alarm next time
Threshold value, RU (Real Usage) indicate currently practical usage amount；Maximum Quota indicates maximum allowable after authenticating every time
Quota, the value are configurable.It should be noted that APM can be with CTF DIAMETER router alignment by union.
In the present example, it is assumed that maximum allowable quota (Maximum Quota)=5M；Usage amount limit
(Allowance)=100M；Alarm threshold value (Alert Threshold) is respectively as follows: 75M, 85M, 95M and 100M；FAPQ=
4M；Effective time (Validity Time, VT)=120s of each allocated quota.
Referring to Fig.1, in step 101a, CTF sends diameter credit control initial request (CCR-I) to APM, wraps in the CCR-I
Include Multiple-Services-Credit-Control (multi-service diameter credit control) [Rating-Group...] etc..
In step 101b, CCR-I is forwarded to OCF by APM.
In a step 102, OCF is according to currently practical usage amount and alarm threshold value next time, allocated quotas.Due to RU=
67M, NAT=75M, therefore, allocated quota Quota=Min (NAT-RU, Maximum Quota)=5M.The quota it is effective
Time (VT)=120s.
In step 103a, OCF returns to diameter credit control and initially confirm (CCA-I) to APM, includes AVPs (category in the CCA-I
Property value to), Multiple-Services-Credit-Control (multi-service diameter credit control) [Rating-Group,
Granted-Service-Unit (Quota=5M), VT=120s...] etc..Wherein, include in Rating-Group is industry
Business is classified, and that include in Granted-Service-Unit is allocated quota Quota=5M.
In step 103b, CCA-I is forwarded to CTF by APM, includes AVPs, Multiple-Services- in the CCA-I
Credit-Control [Rating-Group, Granted-Service-Unit (Quota=5M), VT=120s...] etc..
In step 104a, CTF reports that diameter credit control updates request (CCR-U), wraps in the CCR-U since quota exhausts
Include AVPs, Multiple-Services-Credit-Control [Rating-Group, Used-Service-Unit
(5M) ...] etc..Wherein, include in Used-Service-Unit is this used quota.
In step 104b, APM forwards CCR-U to OCF.
In step 105, OCF carries out charging, currently practical usage amount=72M to the usage amount reported in CCR-U.So
Afterwards, OCF is according to currently practical usage amount and alarm threshold value next time, allocated quotas: Quota=3M, VT=120s.
In step 106a, it includes AVPs in the CCA-U that OCF, which returns to diameter credit control and updates confirmation (CCA-U) to APM,
Multiple-Services-Credit-Control [Rating-Group, Granted-Service-Unit (Quota=
3M), VT=120s...] etc..
In step 106b, APM does not receive the CCA-U from OCF in predetermined time period.So, APM is session
Distribute fixed quota FAPQ=4M, VTFAPQ=120s.
In step 106c, APM returns to CCA-U to CTF, includes AVPs, Multiple-Services- in the CCA-U
Credit-Control [Rating-Group, Granted-Service-Unit (FAPQ=4M), VTFAPQ=120s...] etc..
In step 107a, CTF reports CCR-U since quota exhausts, and includes AVPs, Multiple- in the CCR-U
Services-Credit-Control [Rating-Group, Used-Service-Unit (4M) ...] etc..
In step 107b, APM forwards the CCR-U to OCF.
In step 108, usage amount charging of the OCF to being reported in CCR-U, currently practical usage amount=76M.Due at this time
Alarm threshold value 75M is reached, and alert notification is triggered sending.Then, OCF is according to currently practical usage amount and alarm door next time
Limit value allocated quotas: Quota=5M, VT=120s.
In step 109a, OCF returns to CCA-U to APM, includes AVPs, Multiple-Services- in the CCA-U
Credit-Control [Rating-Group, Granted-Service-Unit (Quota=5M), VT=120s...] etc..
In step 109b, APM forwards CCA-U to CTF, includes AVPs, Multiple-Services- in the CCA-U
Credit-Control [Rating-Group, Granted-Service-Unit (Quota=5M), VT=120s...] etc..
In step 110a, after quota is consumed 3M, the VT of the quota is terminated, then CTF reports CCR-U, it should
It include AVPs, Multiple-Services-Credit-Control [Rating-Group, Used-Service- in CCU-U
Unit (3M) ...] etc..
In step 110b, APM forwards CCR-U to OCF.
In step 111, usage amount charging of the OCF to being reported in CCR-U, currently practical usage amount=79M.Then, OCF
According to currently practical usage amount and alarm threshold value allocated quotas next time: Quota=5M, VT=120s.
In step 112a, OCF returns to CCA-U to APM, includes AVPs, Multiple-Services- in the CCA-U
Credit-Control [Rating-Group, Granted-Service-Unit (Quota=5M), VT=120s...] etc..
In step 112b, APM forwards CCA-U to CTF, includes AVPs, Multiple-Services- in the CCA-U
Credit-Control [Rating-Group, Granted-Service-Unit (Quota=5M), VT=120s...] etc..
In step 113a, CTF reports CCR-U since quota exhausts, and includes AVPs1, Multiple- in the CCR-U
Services-Credit-Control [Rating-Group, Used-Service-Unit (5M) ...] etc..
In step 113b, APM forwards CCR-U to OCF.
In step 114, usage amount charging of the OCF to being reported in CCR-U, currently practical usage amount=84M.Then, OCF
According to currently practical usage amount and alarm threshold value allocated quotas next time: Quota=1M, VT=120s.
In step 115a, OCF returns to CCA-U to APM, includes AVPs, Multiple-Services- in the CCA-U
Credit-Control [Rating-Group, Granted-Service-Unit (Quota=1M), VT=120s...] etc..
In step 115b, APM does not receive the CCA-U from OCF in predetermined time period.So, APM is session
Distribute fixed quota FAPQ=4M, VTFAPQ=120s.
In step 115c, APM returns to CCA-U to CTF, includes AVPs, Multiple-Services- in the CCA-U
Credit-Control [Rating-Group, Granted-Service-Unit (FAPQ=4M), VTFAPQ=120s...] etc..
In step 116a, CTF reports CCR-U since quota exhausts, and includes AVPs, Multiple- in the CCR-U
Services-Credit-Control [Rating-Group, Used-Service-Unit (4M) ...] etc..
In step 116b, APM forwards the CCR-U to OCF.
In step 117, usage amount charging of the OCF to being reported in CCR-U, currently practical usage amount=88M.Due at this time
Alarm threshold value 85M is reached, and alert notification is triggered sending.Then, OCF is according to currently practical usage amount and alarm door next time
Limit value allocated quotas: Quota=5M, VT=120s.
……
In the example in fig 1, due to having used FAPQ, when usage amount reaches 76M and 88M, alert notification is triggered
It issues, although it is desirable that alert notification is triggered sending when usage amount reaches 85M and 85M.

Specific embodiment
Various embodiments of the present invention are described in detail below with reference to attached drawing.
Central scope of the invention is that each OCF is also based on ordering while for ongoing session allocated quotas
The real time billing information of consumer or the current value of the sensitive data according to subscriber generate DAPQ.The DAPQ is sent to APM
And it is stored in APM.If the APM does not receive the new quota from OCF distribution in predetermined time period next time,
The DAPQ of storage is distributed into ongoing session, to guarantee that the session continues.
Specifically, firstly, OCF receives the first request message from CTF forwarded via APM.
Secondly, OCF is in response to first request message, it is ongoing session allocated quotas, and according to subscriber
Real time billing information or the sensitive data according to subscriber current value, generate DAPQ.
OCF can be ongoing session allocated quotas by following formula,
Quota=Min (NAT-RU, Maximum Quota)
Wherein, Quota indicates institute's allocated quota, and NAT table shows alarm threshold value next time, and RU indicates currently practical use
Amount, Maximum Quota indicate maximum allowable quota.
The real time billing information of subscriber may include any one of following or appoint multinomial:
Currently available amount；
Alarm threshold value next time；
Currently practical usage amount.
In one example, OCF can generate DAPQ based on the real time billing information of subscriber in the following manner:
OCF first judge the sum of currently practical usage amount and this allocated quota whether be less than next time alarm threshold value or
Person is equal to alarm threshold value next time.
If it is less than alarm threshold value next time, then it is calculate by the following formula DAPQ,
DAPQ=Min (NAT-RU-Quota, Maximum Quota)
Wherein, Quota indicates institute's allocated quota, and NAT table shows alarm threshold value next time, and RU indicates currently practical use
Amount, Maximum Quota indicate maximum allowable quota.
If being equal to alarm threshold value next time, it is calculate by the following formula DAPQ,
DAPQ=ANDF*Allowance
Wherein, ANDF indicates that acceptable notice discrepancy factor, Allowance indicate usage amount limit.
The sensitive data of subscriber may include any one of following or appoint multinomial:
Amount can be used；
Alarm threshold value；
Actual use amount.
The mapping relations between the sensitive data of subscriber and DAPQ can be pre-generated, and the mapping relations are stored in
In OCF.In operation, OCF can be based on the current value of the sensitive data of subscriber, from mapping relations that are pre-generated and storing
It is middle to search corresponding DAPQ.
For example, if the sensitive data of subscriber be actual use amount, can pre-generate actual use amount with
Mapping relations between DAPQ are simultaneously stored in OCF.During OCF allocated quotas, it can be based on currently practical usage amount,
The DAPQ for corresponding to the current actual use amount is searched from actual use amount and the mapping relations of DAPQ.
It include OCF in first response message is ongoing session finally, OCF sends the first response message to APM
The effective time of allocated quota and the quota, and generate DAPQ and the DAPQ effective time.
After APM receives first response message, store DAPQ in the first response message and DAPQ it is effective when
Between, and the first response message is forwarded to CTF.
In one example, APM can delete the effective time of DAPQ and the DAPQ in the first response message, and will more
The first response message after new is forwarded to CTF.In another example, APM can directly turn complete first response message
It is sent to CTF, namely does not delete the effective time of DAPQ therein He the DAPQ.
Then, APM receives the second request message from CTF and second request message is forwarded to OCF.
Then, APM judge its whether received in predetermined time period from OCF correspond to second request message
The second response message.It include new quota and the effective time of the new quota of OCF distribution in second response message, with
And the effective time of the new DAPQ and the new DAPQ generated.
If APM does not receive the second response message in predetermined time period, APM is ongoing session distribution
The DAPQ of last time storage, and the effective time of the DAPQ He the DAPQ are sent to CTF.
If APM receives the second response message in predetermined time period, APM is stored in second response message
The effective time of new DAPQ and the new DAPQ, and second response message is forwarded to CTF.
In one example, APM can delete the effective of the new DAPQ and new DAPQ in the second response message
Time, and updated second response message is forwarded to CTF.In another example, APM can be directly by complete second
Response message is forwarded to CTF, namely does not delete the effective time of new DAPQ and the new DAPQ therein.
Above scheme of the invention can be applied in a variety of sessions, such as the data session based on DIAMETER agreement.
It hereinafter will be applied to the data session based on DIAMETER agreement for the solution of the present invention to be described in detail.
It is applied in the data session based on DIAMETER agreement Fig. 2 shows according to an embodiment of the invention
The distribution method of DAPQ.In the present embodiment, when OCF allocated quotas and DAPQ, the alert notification thresholding of subscriber is considered.
It is similar with the example in Fig. 1, OCF be ongoing session allocated quota Quota=Min (NAT-RU,
Maximum Quota).In addition, being retouched so that OCF generates DAPQ based on the real time billing information of subscriber as an example in the present embodiment
It states.
It should be noted that APM can be with CTF DIAMETER router alignment by union.
In the present embodiment, similarly, it is assumed that maximum allowable quota (Maximum Quota)=5M；Usage amount limit
(Allowance)=100M；Alarm threshold value (Alert Threshold) is respectively as follows: 75M, 85M, 95M and 100M；It is acceptable
Notice discrepancy factor (Acceptable Notification Deviation Factor, ANDF)=4M；Every sub-distribution
Effective time (Validity Time, VT)=120s of quota and the DAPQ of generation.
Referring to Fig. 2, it includes Multiple- in the CCR-I that in step 201a, CTF, which sends CCR-I to APM,
Services-Credit-Control [Rating-Group...] etc..
In step 201b, CCR-I is forwarded to OCF by APM.
In step 202, OCF is ongoing session allocated quotas, and generates DAPQ.Due to RU=67M, NAT
=75M, therefore, allocated quota Quota=Min (NAT-RU, Maximum Quota)=5M, VT=120s；The DAPQ of generation
=Min (NAT-RU-Quota, Maximum Quota)=Min (75M-67M-5M, 5M)=3M (herein, RU+Quota < NAT),
VTDAPQ=120s.
In step 203, OCF returns to CCA-I to APM, includes AVPs, Multiple-Services- in the CCA-I
Credit-Control [Rating-Group, Granted-Service-Unit (Quota=5M, DAPQ=3M), VT=
120s, VTDAPQ=120s...] etc..

Services-Credit-Control [Rating-Group, Used-Service-Unit (5M) ...] etc..
In step 204b, APM forwards CCR-U to OCF.
In step 205, usage amount charging of the OCF to being reported in CCR-U, currently practical usage amount=72M.Then, OCF
For ongoing session allocated quotas, and generate DAPQ.Due to RU=72M, NAT=75M, therefore, allocated quota
Quota=Min (NAT-RU, Maximum Quota)=3M, VT=120s；The DAPQ=ANDF*Allowance=1M of generation
(herein, RU+Quota=NAT), VTDAPQ=120s.
In step 206a, OCF returns to CCA-U to APM, includes AVPs, Multiple-Services- in the CCA-U
Credit-Control [Rating-Group, Granted-Service-Unit (Quota=3M, DAPQ=1M), VT=
120s, VTDAPQ=120s...] etc..
In step 206b, APM does not receive the CCA-U from OCF in predetermined time period.So, APM is
The DAPQ=3M of the last storage of session distribution of progress, for continuing the session.
In step 206c, APM returns to CCA-U to CTF, includes AVPs, Multiple-Services- in the CCA-U
Credit-Control [Rating-Group, Granted-Service-Unit (DAPQ=3M), VTFAPQ=120s...] etc..
In step 207a, CTF reports CCR-U since quota exhausts, and includes AVPs, Multiple- in the CCR-U
Services-Credit-Control [Rating-Group, Used-Service-Unit (3M) ...] etc..
In step 207b, APM forwards the CCR-U to OCF.
In a step 208, usage amount charging of the OCF to being reported in CCR-U, currently practical usage amount=75M.Due at this time
Alarm threshold value 75M is reached, and alert notification is triggered sending.Then, OCF allocated quotas, and generate DAPQ.Due to RU=
75M, NAT=85M, therefore, allocated quota Quota=Min (NAT-RU, Maximum Quota)=5M, VT=120s；It is raw
At DAPQ=Min (NAT-RU-Quota, Maximum Quota)=Min (85M-75M-5M, 5M)=5M (herein, RU+
Quota < NAT), VTDAPQ=120s.
In step 209a, OCF returns to CCA-U to APM, includes AVPs, Multiple-Services- in the CCA-U
Credit-Control [Rating-Group, Granted-Service-Unit (Quota=5M, DAPQ=5M), VT=
120s, VTDAPQ=120s...] etc..

In step 213b, APM forwards CCR-U to OCF.
In step 214, usage amount charging of the OCF to being reported in CCR-U, currently practical usage amount=84M.Then, OCF
Allocated quotas, and generate DAPQ.Due to RU=84M, NAT=85M, therefore, allocated quota Quota=Min (NAT-RU,
Maximum Quota)=1M, VT=120s；DAPQ=ANDF*Allowance=1M (herein, the RU+Quota=of generation
NAT), VTDAPQ=120s.
In step S215a, OCF returns to CCA-U to APM, includes AVPs, Multiple-Services- in the CCA-U
Credit-Control [Rating-Group, Granted-Service-Unit (Quota=1M, DAPQ=1M), VT=
120s, VTDAPQ=120s...] etc..
In step S215b, APM does not receive the CCA-U from OCF in predetermined time period.So, APM is positive
The DAPQ=1M once stored in the session distribution of progress, for continuing the session.
In step 215c, APM returns to CCA-U to CTF, includes AVPs, Multiple-Services- in the CCA-U
Credit-Control [Rating-Group, Granted-Service-Unit (DAPQ=1M), VTFAPQ=120s...] etc..
In step 216a, CTF reports CCR-U since quota exhausts, and includes AVPs, Multiple- in the CCR-U
Services-Credit-Control [Rating-Group, Used-Service-Unit (1M) ...] etc..
In step 216b, APM forwards the CCR-U to OCF.
In step 217, usage amount charging of the OCF to being reported in CCR-U, currently practical usage amount=85M.Due at this time
Alarm threshold value 85M is reached, and alert notification is triggered sending.Then, OCF allocated quotas, and generate DAPQ.Due to RU=
85M, NAT=95M, therefore, allocated quota Quota=Min (NAT-RU, Maximum Quota)=5M, VT=120s；It is raw
At DAPQ=Min (NAT-RU-Quota, Maximum Quota)=Min (95M-85M-5M, 5M)=5M (herein, RU+
Quota < NAT), VTDAPQ=120s.
In the embodiment of fig. 2, by using DAPQ, alert notification is just touched on the point that usage amount reaches 75M and 85M
