Description

Prepayment charging system and charging information collecting and reporting method

Technical field

The present invention relates to mobile communication system, particularly a kind of prepayment charging system and prepaid user charging information gathering and reporting method.

Background technology

Extensive use along with the flourish and wireless network of internet service, GPRS (General PacketRadio Service, GPRS), 3G, WiMAX (Worldwide InteroperabilityMicrowave Access, micro-wave access to global intercommunication) and B3G wireless systems such as (Beyond 3G, back 3G) obtained a large amount of application and concern.The increase of number of users and the increase of user's request provide new demand for wireless access network system: requirement can be supported big capacity, the multiple business that big data quantity and different service quality require.

Wireless access network finish mainly that business provides and the mobile subscriber between Packet Service transmit or the function of route, how to add up charge informations such as offering user's data amount/service time and be a very important aspect in the communication system.As shown in Figure 1, be existing WiMAX network architecture system figure, comprise MSS (Mobile Subscribe Station, mobile subscriber station), ASN (Access Service Network, access service network) and CSN (Connectivity Service Network, connectivity serving network), wherein:

MSS is a mobile subscriber terminal equipment, and the user uses this devices accessing WiMAX network;

ASN comprises BS (Base Station, base station) and ASN-GW (Access Service Network GateWay, access service network gateway) etc., is used to the WiMAX terminal equipment that the network function set of wireless access service is provided.As: based on as described in BS functions such as the compression of being connected of BS and MSS, RRM, measurement and power control, air interface data and encryption are provided; Based on described ASN-GW, for MSS authentication function provides the proxy function, supports the network of NSP to find and select, provide for MSS the functions such as Relay function (as the relaying of IP address assignment message), RRM of L3 information.

CSN is used to the WiMAX terminal that IP is provided Connection Service, as: for MSS distributing IP address, provide Internet to insert, AAA proxy or server are provided, authorization control based on the user is provided, ASN is provided the tunnel to CSN, be equivalent to the tunnel between the CSN, the switching between the different ASN under the HA (home agent) in the mobile IP technology, the charging that WiMAX user is provided and the clearing between the operator, the roaming condition, and various WiMAX service (as location-based business, multi-medium multi-packet broadcasting and broadcasting service, IP Multimedia System business) etc.

The process of transfer of data between each network element is still described in conjunction with Fig. 1 below:

The grouping busihess data message of descending MSS is by the Interface R3 between HA among the CSN and the ASN-GW among the ASN (being referred to as anchor ASN-GW), be sent to the ASN from the HA of CSN, and by the ASN-GW of ASN-GW process ASN inside and the R6 interface between the BS, and the R1 interface between BS and the MSS sends to the MSS data on the MSS;

If the ASN-GW (being referred to as to serve ASN-GW) of the BS that ASN-GW that links to each other with HA among the CSN and control MSS insert is not simultaneously, the grouping busihess data of descending MSS newspaper from the HA of CSN by the Interface R3 between the ASN-GW HA and the ASN, be sent among the ASN, and send on the MSS through the R6 interface between the inner anchor ASN-GW of ASN and the Interface R4, ASN-GW and the BS that serve between the ASN-GW and the R1 interface between BS and the MSS data MSS by anchor ASN-GW.Upstream data then is delivered to the CSN along opposite path from MSS and reaches end subscriber.

As mentioned above, the data path that corresponding uplink and downlink is all arranged for each Business Stream of each MSS in the interface of ASN inside, these all can require according to the QoS (Quality of Service, service quality) of each Business Stream when each Business Stream is set up and the employing mode of data path and setting up.When this service ending, when just Business Stream is ended, just need to discharge corresponding data path.User for pre-payment, general every next session at first, accounting server among the CSN or charging proxy wherein, from Online Charging System, apply for charging limits such as time/flow for this session distribution, and threshold value, these threshold values are used for when the remaining limit of charging information collecting NE Discovery is lower than this threshold value reporting the charge information of MSS simultaneously to the more limit of accounting server/agent application.

Still as shown in Figure 1, in the WiMAX system, in the prior art, data traffic in the charge information, duration etc. will be responsible for collection by service ASN-GW, and the data traffic that sends on eating dishes without rice or wine/receive, obtain the information of eating dishes without rice or wine such as data traffic confirmed, then collected from BS by service ASN-GW, service ASN-GW merges afterwards and reports accounting server.

Here the problem of Cun Zaiing is: service ASN-GW is as the intermediate NE of the transmission of data flow in ASN of MSS, carry out charging statistics and collecting function and have certain irrationality, because this can not characterize out the degree of support of ASN for the transfer of data of this MSS, can not reflect the data volume of this ASN well to this MSS of CSN transmission.

And moving along with MSS, the service ASN-GW of MSS correspondence will change, for keeping the continuity of charge information, part charge information and charging amount surplus value that the former service ASN-GW of this MSS needs to have collected send to new service ASN-GW, perhaps send to accounting server/agency, send to new service ASN-GW again by accounting server/agency, this processing mode has proposed the expense of too much transfer resource and the consistency assurance function of metering data to ASN, this is more obvious under the scene of fast moving, causes too much metering data transmitting between the new and old service ASN-GW or serving between ASN-GW and the accounting server/agency and transmit.

Moreover, owing to have certain correlation between charging and authentication, the authorization function module, and at present in the WiMAX system Authentication Authorization client be not and serve the ASN-GW correspondence, also be irrational therefore by serving the ASN-GW collecting charging information.

For realizing the collection of prepaid user charging information, be provided with the charging information collecting module in the charging information collecting network element, as shown in Figure 2, Fig. 2 only is that example describes with BS1, other are responsible for all being provided with identical charging information collecting module on all network elements of collecting charging information, the charging information collecting module is used for specifically carrying out the collection of conversation charging information, and whether monitors charging amount surplus value simultaneously above being equal to or less than threshold value, if then trigger the charge information that reports collection.

A kind of MSS as shown in Figure 2 moves handoff scenario, when supposing that MSS initially inserts on BS3, shown in Fig. 2 chain-dotted line, the R1 interactive interfacing of data flow between R6 interface, BS3 and MSS between the Interface R3 between HA and the ASN-GW1, ASN-GW1 and the BS3, Accounting Client is positioned on the ASN-GW1; After MSS moves and switches to BS1, the R1 interactive interfacing of data flow between R6 interface, BS1 and MSS between the Interface R4 between the Interface R3 between HA and the ASN-GW1, ASN-GW1 and the ASN-GW2, ASN-GW2 and the BS1 inserts the anchor ASN-GW of session and corresponding Accounting Client and remains unchanged before and after switching.

In the charging method of the present invention, the network element of concrete collecting charging information can be BS or the anchor ASN-GW that inserts session, also be to collect simultaneously by BS and anchor ASN-GW, be applied in charging method in the above-mentioned charge system with specific embodiment explanation below, in the following embodiments, what concrete execution charging information collecting and charging amount surplus value were monitored is the charging information collecting module that is arranged on BS and/or the ASN-GW, for convenience of description, and explanation no longer one by one.

Embodiment one

By the BS collecting charging information that inserts session, as shown in Figure 3, charging flow comprises the steps:

S101, Accounting Client are after receiving the success of subscription authentication authorization identifying, obtain to distribute to the charging amount and the threshold value thereof of session among accounting server/agency from CSN, and these charging amounts and corresponding threshold value are carried at the BS that notifies the access session in the prepaid accounting response message;

When the surplus value that S102, BS monitor certain charge information amount is equal to or less than threshold value, the charge information that at this session need collect of statistics collection on BS, and charge information is carried at reports service ASN-GW in the prepaid accounting request message;

S103, service ASN-GW are forwarded to Accounting Client with the prepaid accounting request message that this carries charge information;

The prepaid accounting request message of this session of this MSS that S104, Accounting Client report BS reports to accounting server/agency, applies for new amount;

In said process, the charge information that Accounting Client reports accounting server/agency at every turn is all charge informations that begin to count from this session, if the charge information that BS reports was added up stage by stage according to the time interval that reports at every turn, then Accounting Client need add up merging processing behind all charge informations that BS reports; If the charge information that BS reports also is the charge information that begins to collect according to session at every turn, then Accounting Client directly reports.

Charge information comprises session traffic information, Session Time information and session air interface information, air interface information generally comprises air interface and sends/and data traffic that the data traffic that receives and having obtained is confirmed.Accounting Client be collected and be reported to all charge informations all can by BS, also can collect Session Time information in this locality by Accounting Client, if the latter, Accounting Client reports accounting server/agency after also needing to merge the temporal information of oneself collecting.

Accounting server/agent allocation among S105, the CSN is given the new amount of session, and these amounts are notified to Accounting Client;

S106, Accounting Client return these amounts notices BS to step S102, if BS monitors the surplus value of certain charge information amount when being equal to or less than threshold value once more, statistics collection on BS the charge information that need collect at this session and report;

In the above-mentioned steps,, these amounts and threshold value are notified to Accounting Client if the accounting server/agent allocation among the CSN is given the new amount of this session; Accounting Client is distributed to BS with these amounts and threshold value, otherwise when accounting server/agency refusal was distributed to the new amount of this session, initiation session was ended flow process, comprises the steps S107～S110:

When the accounting server among S107, the CSN/agency refusal is distributed to the new amount of session, in sending to the prepaid accounting response message of Accounting Client, carry refusal information;

S108, Accounting Client send the prepaid accounting response message by service ASN-GW to BS, carry the sign of session stop in this message, are used to notify BS to report the final charge information of this MSS session;

S109, BS collect the final charge information of MSS and send to Accounting Client by service ASN-GW, will report the back to discharge at the charging resource of this session then;

S110, Accounting Client report to accounting server/agency with the final charge information of this session of this MSS, will report the back to discharge at the charging resource of this session then, carry the session stop sign in the report message.

Can also comprise that accounting server/agency returns a step that finishes response.

Above-mentioned steps S108～S110 also can initiatively be ended to initiate after the abort message of this MSS session receiving the user by Accounting Client.

In above-mentioned charging process, charge information need and report by the BS collection, because BS directly connects MSS by the R1 air interface, can accurately add up packet sum and byte number sum that the MSS side is received and dispatched in this session, has improved the charging precision;

When being applied to this charge system, even MSS switches to BS2 by BS1 in session is carried out, owing to connect by interface between Accounting Client and the ASN-GW, not binding one by one, do not need to change the position of Accounting Client, avoid frequent Accounting Client migration and the problem of transmission of charge information between new and old Accounting Client, therefore guaranteed the continuity of charging and carrying out smoothly of session.

Flow process by the independent collecting charging information of anchor ASN-GW is similar with embodiment, and wherein, air interface information can send to anchor ASN-GW by BS in conversation procedure, also can ask BS to report before reporting charge information by anchor ASN-GW.

Embodiment two

Utilize BS and the anchor ASN-GW method of collecting charging information simultaneously, technical conceive comprises the steps:

1, Accounting Client is after receiving the success of subscription authentication authorization identifying, accounting server among the CSN/agency sends charging amount and the threshold value that this session of advice of charge Accounting Client distributes, (if session well afoot, so then accounting server/the agent application of initiatively being initiated in CSN by Accounting Client distributes charging amount and threshold value for new session);

2, Accounting Client begins charging amount and threshold value notice anchor ASN-GW to charge and/or begins to charge by service ASN-GW notice BS;

BS or anchor ASN-GW are responsible for monitoring and collecting the charge information that provides and can be pre-configured on the Accounting Client, by Accounting Client at conversation initial time notice BS or anchor ASN-GW, if all information all by one of them network element monitoring and collection, then do not need to notify another network element;

Perhaps, BS or anchor ASN-GW are responsible for monitoring and collecting the charge information that provides can be pre-configured in BS and/or anchor ASN-GW, only need Accounting Client with the amount and threshold value notice BS or the anchor ASN-GW that distribute, if all amount/threshold informations all by one of them network element monitoring, then do not need to notify another network element.

3, for each session, on BS and anchor ASN-GW, all can write down and collect corresponding charge information, when the surplus value of finding a certain charging amount (service time/or data traffic) is lower than threshold value, this network element just needs to trigger the process that Accounting Client starts the more charging amounts of application so, is divided into following two kinds of situations:

If the process of the more charging amounts of application that BS triggers, BS sends to the charge information of its required monitoring collection on the service ASN-GW so, service ASN-GW is forwarded to Accounting Client with this information, the charge information that Accounting Client notice anchor ASN-GW collects its required monitoring reports Accounting Client, Accounting Client merges charge information and reports accounting server/agency, applies for the more multi-prepayment amount (accounting server/agency will or directly apply for new charging amount by other accounting servers from Online Charging System) of this session simultaneously;

If the process of the more charging amounts of application that anchor ASN-GW triggers, the charge information that anchor ASN-GW collects its required monitoring sends Accounting Client, the charge information that Accounting Client is collected its required monitoring by service ASN-GW notice BS collecting and reporting, the charge information that BS collects its required monitoring sends on the service ASN-GW, service ASN-GW is forwarded to Accounting Client with this information, Accounting Client merges charge information and reports accounting server/agency, applies for the more multi-prepayment amount (accounting server/agency will or directly apply for new charging amount by other accounting servers from Online Charging System) of this session simultaneously.

In said process, Accounting Client is receiving certain network element (BS or anchor ASN-GW) is lower than the information that threshold value reports owing to the charge information of being monitored after, receive the charge information message that another network element (anchor ASN-GW or BS) reports again, if this message and Accounting Client do not match to the notice collecting and reporting message of its transmission, it promptly not the message response that needs the charge information of monitoring collection, Accounting Client will be ignored this reporting information so, and wait for the response reporting information of this network element after receiving the notification message of Accounting Client.

Perhaps, Accounting Client receives that earlier the charge information that BS initiates reports, and Accounting Client requires metering data to anchor ASN-GW then; Before anchor ASN-GW receives that this requires, find that the information that detects has been lower than threshold value, so also the charge information that can initiate reports, if the priority according to anchor ASN-GW is higher than BS, Accounting Client is after the charge information of receiving anchor ASN-GW initiation reports so, will ask metering data to BS, the Accounting Client data of just utilizing data that BS reported afterwards and anchor ASN-GW to report merge then.

4, return more session charging amount and threshold value as accounting server/agency, then Accounting Client is with these charging amounts with threshold value is notified anchor ASN-GW respectively and/or by service ASN-GW notice BS;

When Accounting Client receives the session stop message of this MSS or charging amount that accounting server/agency returns and threshold value when distributing failure (promptly this prepaid user does not have available amount) message, Accounting Client initiation session abort process, at this moment, go up collecting charging information from anchor ASN-GW if desired, Accounting Client is notified (may carry the sign of session stop in this message) to the request that anchor ASN-GW sends this conversation charging information that reports this MSS, the charge information at this session of anchor ASN-GW statistics collection on this equipment, and report the charge information of being monitored to give Accounting Client; Go up collecting charging information if also need from BS, Accounting Client sends the notice request (may carry the sign of session stop in this message) of this conversation charging information that reports this MSS simultaneously to service ASN-GW, service ASN-GW is with this request message notice BS, the charge information that the needs monitoring at this session of BS statistics collection on this equipment collected also reports service ASN-GW, and service ASN-GW directly transmits Accounting Client with the charge information that BS sends up; Accounting Client merges these charge informations, and the charge information of this session of this MSS is reported to accounting server/agency, and this session stop of notice accounting server/agency.

If carry the sign of session stop in request reports the message of this conversation charging information of this MSS, the network element that receives this message so will stop to charge, and discharge the charging resource after reporting charge information; If do not end session identification, then may notify each charging network element to discharge the charging resource by other network elements.

Session can be at a Business Stream or data path or at a MSS, and concrete condition will be according to the actual requirements and to Accounting Client setting/configuration.Charge information mainly is data traffic and service time, and wherein data traffic comprises: up byte number and/or upstream data bag number, descending byte number and/or downlink data packet number etc.Wherein, the charge information of the data flow of IP and wireless aspect etc. must be provided by anchor ASN-GW and/or BS, information such as Session Time can be directly collected or collected by anchor ASN-GW or BS at Accounting Client to be provided, can formulate neatly as for the concrete division of labor between anchor ASN-GW and the BS, BS also needs extra some information of collecting air interface that increase, and the specifying information of air interface then requires to determine according to the charging of different system.

In the following examples, be without loss of generality, we suppose that Accounting Client, anchor ASN-GW and service ASN-GW are set to different ASN-GW entities respectively in networking.

Under single session case, anchor ASN-GW and BS finish the monitoring and the collection of part charge information separately and finish end session flow process as shown in Figure 4, specifically comprise the steps:

S201, Accounting Client are after receiving the success of subscription authentication authorization identifying, obtain to distribute to the charging amount and the threshold value thereof of session among accounting server/agency from CSN, and these charging amounts and corresponding threshold value are carried at BS and the anchor ASN-GW that notice is relevant respectively in the prepaid accounting response message begin charging;

Wherein, the charge information of the data flow of IP and wireless aspect etc. must be provided by anchor ASN-GW and/or BS, information such as Session Time can be directly collected or collected by anchor ASN-GW or BS at Accounting Client to be provided, can formulate neatly as for the concrete division of labor between anchor ASN-GW and the BS, BS also needs extra some information of collecting air interface that increase, and the specifying information of air interface then requires to determine according to the charging of different system.

Following step S202～S207 is the process by the more charging amounts of application of BS triggering:

When the surplus value that S202, BS monitor certain charge information amount is equal to or less than threshold value, the charge information that at this session need collect of statistics collection on BS, and charge information is carried at reports service ASN-GW in the prepaid accounting request message;

S203, service ASN-GW are forwarded to Accounting Client with the prepaid accounting request message that this carries charge information;

S204, Accounting Client send the charge information request message to anchor ASN-GW, and notice anchor ASN-GW needs the collecting and reporting charge information;

S205, anchor ASN-GW statistics collection on this equipment the charge information that need collect at this session and be carried in the charge information response message and report Accounting Client;

Report to accounting server/agency after the prepaid accounting request message of this session of this MSS that S206, Accounting Client report BS and anchor ASN-GW merges, apply for new amount;

In said process, the charge information that Accounting Client reports accounting server/agency at every turn is all charge informations that begin to count from this session, if the charge information that BS and anchor ASN-GW report was added up stage by stage according to the time interval that reports at every turn, then Accounting Client need merge processing behind all charge informations that totally BS and anchor ASN-GW report respectively; If the charge information that BS and anchor ASN-GW report also is the charge information that begins to collect according to session at every turn, then Accounting Client directly merges.When if the temporal information of chargeing is collected voluntarily by Accounting Client, Accounting Client also needs to merge the temporal information of oneself collecting.

Accounting server/agent allocation among S207, the CSN is given the new amount of session, and these amounts are notified to Accounting Client, and Accounting Client is with these amounts notice BS and anchor ASN-GW;

Following step S208～S213 is the process by the more charging amounts of application of anchor ASN-GW triggering:

S208, anchor ASN-GW monitor certain charge information surplus value and are lower than threshold value, the charge information that at this session need collect of statistics collection on anchor ASN-GW, and charge information is carried in the pre-payment request message reports Accounting Client;

S209, Accounting Client send the charge information request message needs collecting charging information to service ASN-GW notice;

S210, service ASN-GW go up this charge information forwards to notify to BS needs charging information collecting;

S211, BS statistics collection on this equipment the charge information that need collect at this session and be carried at and report service ASN-GW in the charge information response message;

S212, service ASN-GW are sent to Accounting Client with this charge information response message;

Report to accounting server/agency after the prepaid accounting request message of this session of this MSS that S213, Accounting Client report BS and anchor ASN-GW merges, apply for new amount;

If the accounting server/agent allocation among the CSN is given the new amount of this session, these amounts and threshold value are notified to Accounting Client; Accounting Client is distributed to BS and anchor ASN-GW with these amounts and threshold value, otherwise when the accounting server among the CSN/agency refusal was distributed to the new amount of this session, initiation session was ended flow process, comprises the steps S214～S217:

When the accounting server among S214, the CSN/agency refusal is distributed to the new amount of session, in sending to the prepaid accounting response message of Accounting Client, carry refusal information;

S215, Accounting Client send the prepaid accounting response message to anchor ASN-GW, carry the sign of session stop in this message, the final charge information of this session that is used to notify anchor ASN-GW to report this MSS;

After anchor ASN-GW receives the prepaid accounting response message that carries the session stop sign, statistics collection on this equipment at the final charge information of this session and be carried in the prepaid accounting request message and report Accounting Client, will report the back to discharge at the charging resource of this session then.

S216, simultaneously Accounting Client sends the prepaid accounting response message to service ASN-GW, carries the sign of session stop in this message, the final charge information of this session that is used to notify BS to report this MSS;

Service ASN-GW is transmitted to BS with the prepaid accounting response message that this carries the session stop sign; The BS statistics collection on this equipment at the final charge information of this session and be carried at and report service ASN-GW in the prepaid accounting request message, the prepaid accounting request message that service ASN-GW carries this charge information again is transmitted to Accounting Client, and BS will discharge after reporting the prepaid accounting request message at the charging resource of this session then;

S217, Accounting Client merge the final charge information of this session of this MSS, report to accounting server/agency then, comprise the session stop sign, will report the back to discharge at the charging resource of this session then.

Above-mentioned steps S215～S217 also can initiatively be ended to initiate after the abort message of this MSS session receiving the user by Accounting Client.

In above-mentioned charging process, charge information need be collected simultaneously and reported by BS and anchor ASN-GW, because BS directly connects MSS by the R1 air interface, can accurately add up packet sum and byte number sum that the MSS side is received and dispatched in this session, improved the charging precision;

And anchor ASN-GW directly connects CSN by Interface R3 can accurately add up the data volume that CSN issues, or MSS sends to the data volume of CSN, has therefore also improved the charging precision;

When being applied to this charge system, even MSS switches to BS3 by BS2 in session is carried out, owing to connect by interface between Accounting Client and the ASN GW, therefore not binding has one by one guaranteed the continuity of charging and carrying out smoothly of session.

Embodiment three,

Another kind utilizes BS and the anchor ASN-GW method of collecting charging information simultaneously, and technical conceive comprises the steps:

1, Accounting Client is after receiving the success of subscription authentication authorization identifying, accounting server among the CSN/agency sends charging amount and the threshold value that this session of advice of charge Accounting Client distributes, if (user has had the session of well afoot, so then accounting server/the agent application of initiatively being initiated in CSN by Accounting Client distributes the charging amount for new session, and threshold value);

2, Accounting Client sends to notice anchor ASN-GW with charging amount and threshold value and begins to charge, and anchor ASN-GW sends to the BS notice by service ASN-GW again to begin to charge;

BS or anchor ASN-GW are responsible for monitoring and collecting the charge information that provides and can be pre-configured on the Accounting Client, send to BS or anchor ASN-GW when the conversation initial simultaneously by Accounting Client, if all information all by one of them network element monitoring and collection, then do not need to notify another network element;

Perhaps, BS or anchor ASN-GW are responsible for monitoring and collecting the charge information that provides can be pre-configured in charging BS and/or anchor ASN-GW, only need Accounting Client with the amount and threshold value notice BS or the anchor ASN-GW that distribute, if all amount/threshold informations all by one of them network element monitoring, then do not need to notify another network element.

3, for each session, on BS and anchor ASN-GW, all can write down and collect corresponding charge information, be lower than the threshold value of setting when the surplus value of finding a certain index (service time/or data traffic), this network element just needs to trigger the process that Accounting Client starts the more charging amounts of application so, is divided into following two kinds of situations:

1), if the process of the more charging amounts of application that BS triggers, BS sends to the charge information of its required monitoring collection on the service ASN-GW so, service ASN-GW is forwarded to this information on the anchor ASN-GW, the information that charge information that anchor ASN-GW collects its required monitoring and BS report gathers and reports Accounting Client, and Accounting Client reports accounting server/agency to apply for the more multi-prepayment amount (accounting server/agency will or directly apply for new charging amount by other accounting servers from Online Charging System) of this session simultaneously charge information;

2), if the process of the more charging amounts of application that anchor ASN-GW triggers, anchor ASN-GW reports charge information by service ASN-GW notice BS, the charge information that BS collects its required monitoring sends on the service ASN-GW, service ASN-GW is forwarded to this information on the anchor ASN-GW, (can collect when anchor ASN-GW triggers by this charge information with the charge information that its required monitoring is collected for anchor ASN-GW, also can be to collect later in the response that anchor ASN-GW receives BS) and the information that reports of BS gather and report Accounting Client, Accounting Client reports accounting server/agency to apply for the more multi-prepayment amount (accounting server/agency will or directly apply for new charging amount by other accounting servers from Online Charging System) of this session simultaneously charge information.

In this process, if anchor ASN-GW is after reporting charge information by service ASN-GW notice BS, receive the reporting information that BS sends, but report request message with anchor ASN-GW notice BS and do not match, promptly be not the response of BS to this message, the message that initiatively reports but BS monitors also simultaneously that certain charge information amount surplus value of its monitoring is lower than threshold value, anchor ASN-GW will ignore this reporting information so, and wait for that BS reports the response reporting information of request message receiving anchor ASN-GW notice BS.

4, return more session amount as accounting server/agency, then the charging amount that Accounting Client is new with these charging amounts and threshold value notice anchor ASN-GW and/or by anchor ASN-GW and the new charging amount of service ASN-GW notice BS.

Return the distribution failed message if receive session stop message or the accounting server/agency of this MSS when Accounting Client, Accounting Client initiation session abort process then specifically comprises:

Accounting Client is notified (may carry the sign of session stop in this message) to the request that anchor ASN-GW sends this conversation charging information that reports this MSS, the charge information at this session of anchor ASN-GW statistics collection on this equipment, go up collecting charging information if also need from BS, need anchor ASN-GW to send the notice request (may carry the sign of session stop in this message) of this conversation charging information that reports this MSS simultaneously to service ASN-GW, service ASN-GW is with this request message notice BS, the charge information that the needs monitoring at this session of BS statistics collection on this equipment collected also reports service ASN-GW, and service ASN-GW directly is transmitted to anchor ASN-GW with the charge information that BS sends up; Otherwise do not need anchor ASN-GW notice BS to report charging message.

(this charge information can be to collect after anchor ASN-GW receives the charging request message of Accounting Client to the charge information that charge information that anchor ASN-GW collects BS and anchor ASN-GW collect, also can be the response collection later on that receives BS at anchor ASN-GW) merge, and the charge information after will merging reports Accounting Client, Accounting Client reports to accounting server/agency with the charge information of this session of this MSS then, and this session stop of notice accounting server/agency.

If in request reports the message of this conversation charging information of this MSS, carry the sign of session stop, receive this message so after, this network element will stop to charge, and report the back to discharge the charging resource.If do not end session identification, so will be by the release that plays charging resource in his the network element informing charging unit.

For the content of charge information, the charge information of the data flow of IP and wireless aspect etc. must be provided by anchor ASN-GW and/or BS, provides but can be directly collect or collected by anchor ASN-GW or BS at Accounting Client for information such as Session Times.

Session can be at a Business Stream or data path or at a MSS, and concrete condition will be according to the actual requirements and to Accounting Client setting/configuration.Charge information mainly is data traffic and service time, and wherein data traffic comprises: up byte number, upstream data bag number, descending byte number and downlink data packet number etc.Wherein, the charge information of the data flow of IP and wireless aspect etc. must be provided by anchor ASN-GW and/or BS, information such as Session Time can be directly collected or collected by anchor ASN-GW or BS at Accounting Client to be provided, can formulate neatly as for the concrete division of labor between anchor ASN-GW and the BS, BS also needs extra some information of collecting air interface that increase, and the specifying information of air interface then requires to determine according to the charging of different system.

As shown in Figure 5, idiographic flow comprises the steps:

S301, Accounting Client are after receiving the success of subscription authentication authorization identifying, obtain to distribute to the charging amount and the threshold value thereof of session among accounting server/agency from CSN, and these charging amounts and corresponding threshold value be carried at send to anchor ASN-GW notice in the prepaid accounting response message and begin to charge, anchor ASN-GW begins the BS notice that this prepaid accounting response message that carries charging amount and threshold value thereof is transmitted to charge;

Following step S302～S306 is the process by the more charging amounts of application of BS triggering:

When the surplus value that S302, BS monitor certain charge information amount is equal to or less than threshold value, the charge information that at this session need collect of statistics collection on BS, and charge information is carried at reports service ASN-GW in the prepaid accounting request message;

S303, service ASN-GW are forwarded to this prepaid accounting request message that carries charge information on the anchor ASN-GW;

S304, anchor ASN-GW statistics collection on this equipment the charge information that need collect at this session and merge with charge information that the BS that receives reports;

S305, anchor ASN-GW are carried at the charge information that merges in the prepaid accounting request message and report Accounting Client;

S306, Accounting Client report to accounting server/agency with the charge information after the merging of this session of this MSS, and apply for new amount;

Accounting server among S307, the CSN/agency distributes the new charging amount of this session according to the charge information of this session of receiving, and new charging amount and threshold value be carried in the prepaid accounting response message be notified to Accounting Client; Accounting Client is transmitted to BS with new charging amount and these amount notice anchors of threshold value ASN-GW again by anchor ASN-GW;

Following step S308～S314 is the process by the more charging amounts of application of anchor ASN-GW triggering:

S308, anchor ASN-GW monitor certain charge information amount surplus value when being lower than corresponding threshold value, send the charge information request message and notify BS to need collecting charging information to service ASN-GW;

S309, service ASN-GW are sent to this charge information request message on the BS;

After S310, BS receive the charge information request message, statistics collection on this equipment the charge information that need collect at this session and be carried at and report service ASN-GW in the charge information response message;

S311, service ASN-GW are sent to this charge information response message on the anchor ASN-GW;

S312, anchor ASN-GW statistics collection on this equipment the charge information that need collect at this session and merge with charge information that the BS that receives reports;

S313, anchor ASN-GW are carried at the charge information that merges in the prepaid accounting request message and report Accounting Client;

S314, Accounting Client report to accounting server/agency with the charge information after the merging of this session of this MSS, and apply for new amount;

In said process, the charge information that Accounting Client reports accounting server/agency at every turn is all charge informations that begin to count from this session, if the charge information that BS and anchor ASN-GW report was added up stage by stage according to the time interval that reports at every turn, then Accounting Client need merge processing behind all charge informations that totally BS and anchor ASN-GW report respectively; If the charge information that BS and anchor ASN-GW report also is the charge information that begins to collect according to session at every turn, then Accounting Client directly reports after receiving the charge information that anchor ASN-GW reports at every turn.When if the temporal information of chargeing is collected voluntarily by Accounting Client, Accounting Client also needs to merge the temporal information of oneself collecting.

If the accounting server/agent allocation among the CSN is given the new amount of this session, these amounts and threshold value are notified to Accounting Client; Accounting Client is distributed to BS and anchor ASN-GW with these amounts and threshold value, otherwise when the accounting server among the CSN/agency refusal was distributed to the new amount of this session, initiation session was ended flow process, comprises the steps S315～S321:

When the accounting server among S315, the CSN/agency refusal is distributed to the new amount of session, in sending to the prepaid accounting response message of Accounting Client, carry refusal information;

S316, Accounting Client send the prepaid accounting response message to anchor ASN-GW, carry the sign of session stop in this message, the final charge information of this session that is used to notify anchor ASN-GW to report this MSS; Anchor ASN-GW transmits the prepaid accounting response message carry the session stop sign by service ASN-GW to BS, the final charge information of this session that is used to notify BS to report this MSS;

S317, service ASN-GW transmit BS with this prepaid accounting response message;

S318, BS statistics collection charge information is reported at the final charge information of this session and by charge response message on this equipment served ASN-GW; And will report the back to discharge at the charging resource of this session;

The charge information that S319, service ASN-GW send up BS directly is transmitted to anchor ASN-GW by charge response message and handles;

S320, the anchor ASN-GW statistics collection final charge information at this session on this equipment merges the final charge information of BS collection and the final charge information of anchor ASN-GW collection, reports Accounting Client; And will report the back to discharge at the charging resource of this session;

S321, Accounting Client are carried at the final charge information after the merging of this session of this MSS in the session charging report request message and report accounting server/agency, and this message comprises the session stop sign; And will report the back to discharge at the charging resource of this session.

Accounting server/agency returns a response message to Accounting Client after receiving session charging report request message.

Above-mentioned steps S115～S117 also can initiatively be ended to initiate after the abort message of this MSS session receiving the user by Accounting Client.

When being applied to this charge system, even MSS switches to BS3 by BS1 in session is carried out, owing to connect by interface between Accounting Client and the ASN-GW, therefore not binding has one by one guaranteed the continuity of charging and carrying out smoothly of session.

Said method can be used for following networking situation:

1, Accounting Client, anchor ASN-GW and service ASN-GW are arranged on separately respectively in three physical entities;

2, Accounting Client is arranged on the anchor ASN-GW, connects anchor ASN-GW by internal interface, but is not together with service ASN-GW; Anchor ASN-GW and service ASN-GW are in the same place, but are not together with Accounting Client; Accounting Client is in the same place with service ASN-GW, but is not together with anchor ASN-GW; Perhaps these three network elements all together.

For above-mentioned second kind of situation, then some related news will become inside story, but not the message that transmits on the interface of ASN inside, perhaps can directly omit.

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.
