Embodiment
Consult shown in Figure 1, in the WiMAX charge system, by the operating position of access service network (ASN) statistics MSS/MS to Internet resources, AAA (checking, mandate, charging) client (AAAClient) generates ticket, and reports aaa server by the interface between ASN and the connection service network (CSN).For visit ground situation, the aaa server on visit ground is transmitted to the ownership place aaa server by agency's (Proxy) function with ticket.
For prepayment service, prepayment client (PPC) by the ownership place aaa server to prepaid server (PPS) application with upgrade quota, the charging center according to the MSS that reports to the Internet resources operating position in real time from user's the account amount of money of examining and making cuts.
In the WiMAX system, accessing business network gate (ASN GW) is from being divided into policy decision point (PDP) and Policy Enforcement Point (PEP) functional entity in logic, and wherein PDP is responsible for the processing of signaling plane, and PEP is responsible for the relevant treatment of data surface.
In the WiMAX system, for the prepayment service that rate is switched, tariff switch point is controlled by prepaid server, the main process that realizes prepayment service as shown in Figure 2:
Step 100, prepaid server (PPS) when issuing charging message, are carried quota information and rate information switching time to Policy Enforcement Point (PEP) in this charging message.
Step 110, Policy Enforcement Point statistics user's charge information.
Step 120, arrive rate switching time, strategy execution point identification charge information is to distinguish the charge information of rate before and after switching.
Step 130, triggering charge information reported event, Policy Enforcement Point reports described prepaid server by charging message with charge information.
Before step 140, prepaid server are switched rate and the charge information of rate after switching report the charging center, the user is chargeed.
Prepaid server comprises prepaid accounting quota (PrepaidAccounting Quota in the charging message that issues, PPAQ) attribute and rate are switched (PrePaidTariffSwitch, PTS) attribute, wherein: VQ in the described PPAQ attribute (flow quota) and DQ (duration quota) parameter are carried allocated quotas, carry by VT (flow threshold) or DT (duration threshold value) and trigger the quota thresholding that reports charge information; TSI (TariffSwitchInterval) parameter in the described PTS attribute is carried rate switching time; Carry the time that appointment reports charge information by TITSU (TimeIntervalafterTariffSwitchUpdate) parameter in the described PTS attribute.
In the charging message that Policy Enforcement Point reports, comprise prepaid accounting quota (PPAQ) attribute and rate and switch (PTS) attribute, wherein: carry the quota of having used by VQ in the PPAQ attribute or DQ parameter, carry the quota of using after the tariff switch point by the VUATS in the PTS attribute (VolumeUsedAfterTariffSwitch) parameter.
Below to realize that by the flow mode prepayment service is that example is elaborated:
VUATS is the flow after the tariff switch point; How long TSI is meant that carrying out rate after (second) switches, this parameter indication PEP from send request or upgrade quota message constantly (time stamp) be tariff switch point after counting what seconds; TITSU referred to before second tariff switch point, and first tariff switch point interior PEP of what seconds is afterwards reported VUATS to PPS; The total flow statistics is in the VQ or DQ of PPAQ, and the traffic statistics after the tariff switch point are in the VUATS of PTS.
If the user has arrived the quota thresholding before TITSU, PEP will send the quota update request, carry VQ in the request, upgrade former because thresholding arrives (" Threshold Reached "), and in PTS, indicate VUATS, PEP will ignore TITSU this moment, need comprise the value of new TSI and TITSU in addition in the AccountingResponse message of ownership aaa server.If the TITSU time arrives, then PEP delivery volume update request indicates VQ in PPAQ, upgrades former because switch renewal (Tariff SwitchUpdate), indicates VUATS in PTS.
Being under the rate handoff scenario of 12:00 and 21:00 at tariff switch point, the flow process of carrying out prepayment service by the flow mode is an example, and the some expense is 10K/$ from 12:00 to 21:00, from 21:00 to next day the 12:00 expense be 20K/$, consult shown in Figure 3ly, realize that the processing procedure of prepayment is as follows:
Step a, the PEP that possesses prepayment client (PPC) ability send the beginning Accounting Request Start message of chargeing to Home AAA (HAAA); Home AAA (HAAA) judges the PEP support prepaid by PPAC; PPS obtains 10$ to the SCP requested fee.PPS returns user's VQ=50K by PPAQ, VT=40K, and TSI=3600S, PPS record allocated quotas 50K is 20K/$ because the current time is 11 rates, is (50K*0.05$/K) so authorize back user's the distribution amount of money.HAAA sends Accounting Response message to PEP, carries above PPAQ information in the message.
Step b, user carry out Operational Visit, PEP statistics user's flow operating position.
Step c, user's use amount reaches 40K, has arrived and has given user's allocated quota thresholding.
After steps d, 11:35 allocation thresholding arrive, PEP will ask quota to be upgraded to HAAA, PEP sends Accounting Request Interim Update message to HAAA, comprise PPAQ in the message, wherein VQ=40K indicates the flow that the user has used 40K, upgrade former because ' threshold reached ', the HAAA request of receiving is transmitted to PPS.
Step e, PPS record tariff switch point (12 point) is user's use traffic 40K before, calculate the flow that the user has used 2$ according to rate 20K/$, also has 8$, PPS is to user's 50K flow of reallocating, PPS writes down to user's allocated quotas 100K, amount of money 5$, VQ=100K in PPAQ, VT=90K, TSI=1500S (25min*60s/min).HAAA sends Accounting Response message to PEP, carries above PPAQ and PTS information in the message.
Step f, 12:00 arrive tariff switch point.
Step g, user carry out Operational Visit, and this moment, PEP added up user's flow operating position.
Step h, user's use amount reaches 90K, has arrived and has given user's allocated quota thresholding.
After step I, 19:00 allocation thresholding arrive, PEP upgrades to HAAA request quota, PEP send Accounting Request Interim Update (comprise PPAQ wherein VQ=90K indicate the flow that the user has used 90K, upgrade former because ' threshold reached ', PTS comprises the flow after the VUATS=10K tariff switch point) give HAAA, the HAAA request of receiving is transmitted to PPS.
Step j, PPS record switching point (12 point) is user's use traffic 80K before, the user uses 10K afterwards, then the user has used 5$ (80K*0.05$/K+10K*0.1$/K), so because the current time is 19 rates is 10K/$, PPS distributes the 40K flow to the user, and record distributes 140K to the user, amount of money 9$ (100K*0.05$/K+40K*0.1$/K), VQ=140K among the PPAQ, VT=130K, TSI=7200S.
Step k, 21:00 arrive tariff switch point.
Step 1, user carry out Operational Visit, PEP statistics user's flow operating position.
Step m, user's use amount reaches 130K, has arrived and has given user's allocated quota thresholding.
After step n, 22:00 allocation thresholding arrive, PEP upgrades to HAAA request quota, PEP send Accounting Request Interim Update (comprise PPAQ wherein VQ=130K indicate the flow that the user has used 130K, upgrade former because " threshold reached ", PTS comprises the flow after the VUATS=20K tariff switch point) give HAAA, the HAAA request of receiving is transmitted to PPS.
Step o, PPS record switching point (12 point) is user's use traffic 100K (80+20) before, and the user uses 30 (10+20) K afterwards, and then the user has used 8$ (100K*0.05$/K+30K*0.1$/K) to also have 2$, and PPS gives user's allocated quotas 10K.So because the current time is 22 rates is 20K/$, PPS writes down to the user and distributes 150K, distributes amount of money 9$ (100K*0.05$/K+40K*0.1$/K+10K*0.05$/K) to use amount of money 8$.VQ=150K among the PPAQ, VT=140K, TSI=50400S.
Step p, user's use amount reaches 140K, has arrived and has given user's allocated quota thresholding.
After step q, 23:00 allocation thresholding arrive, PEP upgrades to HAAA request quota, PEP send Accounting Request Interim Update (comprise PPAQ wherein VQ=140K indicate the flow that the user has used 140K, upgrade former because " threshold reached ", so do not comprise PTS because there is rate to switch) give HAAA, the HAAA request of receiving is transmitted to PPS.
PPS record switching point (12 point) is user's use traffic 110K (80+20+10) before, and the user uses 30K (not changing) afterwards, and then the user has used 8.5$ (110K*0.05$/K+30K*0.1$/K) to also have 1.5$, and PPS gives user's allocated quotas 10K.So because the current time is 23 rates is 20K/$, PPS writes down to the user and distributes 160K (50K+50K+40K+10K+10K), distributes amount of money 10$ (100K*0.05$/K+40K*0.1$/K+10K*0.05$/K+10K*0.05$/K) to use amount of money 8.5$.VQ=160K among the PPAQ, VT=150K, TSI=46800S.PPS detects last capital rationing to the SCP application and distributes, and the capital rationing remaining sum has been 0, sends the ACCT_req request to SCP and distributes new capital rationing.Do not apply for specifically new quota (if apply for, then the last user's of PPS capital rationing will increase the number of applying for) in this flow process.
Step r, user carry out Operational Visit, PEP statistics user's flow operating position.
Step s, user's use amount reaches 150K, has arrived and has given user's allocated quota thresholding.
After step t, 24:00 allocation thresholding arrive, PEP upgrades to HAAA request quota, PEP send Accounting Request Interim Update (comprise PPAQ wherein VQ=150K indicate the flow that the user has used 150K, upgrade former because ' threshold reached ', so do not comprise PTS because there is rate to switch) give HAAA, the HAAA request of receiving is transmitted to PPS.
Step u, PPS record switching point (12 point) is user's use traffic 120K (80+20+10+10) before, the user uses 30K (not changing) afterwards, then the user has used 9$ (120K*0.05$/K+30K*0.1$/K) to also have 1$, so because the current time is 24 rates is 20K/$, PPS can give user's allocated quotas 20K again.VQ=170K among the PPAQ, VT=170K, TSI=43200S.(the assignable capital rationing of PPS is 0, if last PPS is successful to SCP request for funds quota, then PPS will still have the assignable capital rationing of residue, and flow process will repeat aforementioned each step).
Step v, user's use amount reaches 170K, has arrived and has given user's allocated quota thresholding.
Step w, because VQ=VT, so PEP send Accounting Request Stop (comprise PPAQ wherein VQ=170K indicate the flow that the user has used 170K, upgrade former because " quotareached ") give HAAA, the HAAA request of receiving is transmitted to PPS.
Step x, PPS record switching point (12 point) is user's use traffic 140K (80+20+10+10) before, the user uses 30K (not changing) afterwards, then the user has used 10$ (140K*0.05$/K+30K*0.1$/K), because the amount of money that the user distributes has used up PPS and sent Accounting Response message, PEP discharges the user and connects.
At above-mentioned steps b between u, if having disconnected, the user connects or PEP disconnection connection, PEP will send Accounting Response message to AAA, and professional stop (the ClientService termination) of assignable cause client, and AAA transmits this request to PPS.PPS determines the capital rationing of employed flow of user and remaining flow quota correspondence, and sends amount of money return request to SCP.When SCP receives the amount of money return messages of PPS transmission, add this part amount of money to the user account remaining sum.
Though above-mentioned is that example describes in the charge on traffic mode, but be not limited to this, also can be to realize in the time-based charging mode, as adding up in the DQ of PPAQ the total time of using, VUATS is the service time after the tariff switch point etc., its implementation and charge on traffic mode in like manner repeat no more.
Obviously, those skilled in the art can carry out various changes and modification to the present invention and not break away from the spirit and scope of the present invention.Like this, if of the present invention these are revised and modification belongs within the scope of claim of the present invention and equivalent technologies thereof, then the present invention also is intended to comprise these changes and modification interior.
