Description

A kind ofly consume the signing of limit service and manner of execution and system

Technical field

The present invention relates to communication technique field, particularly relate to and a kind ofly consume the signing of limit service and manner of execution and system.

Background technology

Third generation partner program (3rd Generation Partnership Project, referred to as 3GPP) strategy and charging control (Policy and Charging Control, referred to as PCC) framework be a functional framework that can be applied to multiple access technology.Such as, be applied to universal mobile telecommunications system (Universal Mobile Telecommunications System, referred to as UMTS) terrestrial radio access network (UMTS Terrestrial Radio Access Network, referred to as UTRAN), global system for mobile communications (Global system for Mobile Communication, referred to as GSM)/GSM data enhancing evolution (Enhanced Data rates for Global Evolution, referred to as EDGE) wireless access network, grouping system (the Evolved Packet System of intercommunicated wireless local area network (I-WLAN) and evolution, referred to as EPS) etc.

The schematic diagram of the non-roaming framework of Rel-8 PCC (framework 1) that Fig. 1 (a) is correlation technique, is described each logical functional entity in this PCC framework and interface function thereof referring to Fig. 1 (a):

Application Function (Application Function, referred to as AF), provides the access point of service application, and the Internet resources that these service application use need to carry out dynamic policy control.When service surface carries out parameter negotiation, related service information is passed to strategy and charging regulation function entity (Policy and Charging Rules Function by AF, referred to as PCRF), if these business information are consistent with the strategy of PCRF, then PCRF accepts this negotiation; Otherwise PCRF refuses this negotiation, and provide the acceptable service parameter of PCRF in feedback simultaneously.Subsequently, these parameters can be returned to subscriber equipment (User Equipment, referred to as UE) by AF.Wherein, the interface between AF and PCRF is Rx interface.

PCRF is the core of PCC, is responsible for the formulation of strategic decision-making and charging regulation.PCRF provides the network control rule based on business data flow, these network controls comprise the monitoring of business data flow, gate (Gating Control), service quality (Quality of Service, referred to as QoS) control and based on the charging regulation etc. of data flow.The strategy that PCRF is formulated and charging regulation send to strategy and charging execution function entity (Policy and Charging Enforcement Function, referred to as PCEF) perform, meanwhile, PCRF also needs to ensure that these rules are consistent with the CAMEL-Subscription-Information of user.PCRF generate strategy with charging regulation according to comprising: obtain the information relevant to business from AF; User policy, billing control and subscription information is obtained from user-subscribed database (Subscription Profile Repository, referred to as SPR); The information with carrying network of relation is obtained from PCEF.

PCEF, for performing the strategy formulated of PCRF and charging regulation at loading end.Business datum flow filter in the rule that PCEF sends according to PCRF is monitored business data flow, and then performs to these business data flows the strategy and charging regulation that PCRF formulates.When carrying is set up, the rule that PCEF sends according to PCRF carries out QoS mandate, and carries out gate control according to the execution of AF.According to the charging regulation that PCRF sends, PCEF performs the operation of corresponding service data flow charge, and charging both can be online charging, also can be offline charging.If online charging, then PCEF needs and Online Charging System (Online Charging System, referred to as OCS) carry out credit management together.During offline charging, exchange correlation charge information between PCEF and off-line accounting system (Offline Charging System, referred to as OFCS).Interface between PCEF and PCRF is Gx interface, and the interface between OCS is Gy interface, and the interface between OFCS is Gz interface.PCEF is usually located in the gateway (Gate-Way, referred to as GW) of network, as the GGSN (GGSN) in GPRS and the packet data gateway in I-WLAN (Packet Data Gateway, referred to as PDG).

Bearing binding and event reporting function entity (Bearer Binding and Event Reporting Function, referred to as BBERF), its function comprises bearing binding, the checking of up bearing binding and event report.When UE is accessed by E-UTRAN, and when adopting PMIPv6 agreement between S-GW and P-GW, BBERF is located in S-GW, when UE is by the access of trusted non-3 GPP access system, BBERF is positioned at trusted non-3 GPP access gateway, when UE by the access of trustless non-3 GPP access system time, BBERF is positioned at the packet data gateway (Evolved Packet Data Gateway, referred to as ePDG) of evolution.Now, PCEF no longer performs bearing binding function.

User-subscribed database (SPR) stores the user policy, billing control and subscription information relevant to charging with policy control.Interface between SPR and PCRF is Sp interface.

Online Charging System (OCS), carries out the control and management of user credit under online charging mode together with PCEF.

Off-line accounting system (OFCS), completes the billing operation under offline charging mode together with PCEF.

As shown in Fig. 1 (b), for disposing the Organization Chart (framework 2) of Sy interface under Fig. 1 (a) framework.Interface between OCS and PCRF is Sy interface, and the charging policy session on this interface is for transmitting accounting-related information.PCRF obtains accounting-related information from OCS, as one of foundation information formulating PCC/QoS rule.After OCS detects and authorizes quota (such as consumption threshold value) to arrive, charging policy report can be initiated to PCRF, trigger PCRF initiation session modification process, upgrade dependency rule.

It is access packet data network (Packet Data Network that above PCC framework achieves UE by each functional entity, referred to as PDN) IP that sets up connects the policy and charging control of Access Network (IP Connectivity Access Network, referred to as IP-CAN) session.

At present, the QoS of PCC framework support consumption limit service (spending limits) controls.The QoS of so-called consumption limit service controls to refer to that user has contracted certain business (such as video request program), user can in special time the certain limit of (such as every day) cumulative consumption (such as 10 yuan), enjoy higher QoS in this section of consumption to ensure, when cumulative spend amount exceedes this limit, lower QoS can only be obtained and ensure.The feature of this kind of business is that operator needs to change corresponding qos policy according to the situation of consumption, and consumption information is preserved in OCS.When user carries out this kind of business, when policy decision entity (PCRF) is generated strategy, need the consumption of perception user thus generate strategy; Or expand existing billing mechanism, special process is adopted to the charging of this kind of business.

In prior art, the credit management functionality of business has been consulted by PCEF and OCS, the information such as the charging policy (as rate group RG) in the CCR message that OCS sends according to PCEF, and combine local billing mechanism and carrier policy carries out credit management and control to the business that PCEF applies for, return CCA message to PCEF, carry the business credit quota of mandate in the message to PCEF.Existing online charging mechanism, when to be this business ask credit line to OCS to PCEF, if the business that this RG is corresponding is limited, OCS can return " out of credit ", continuation reports " out of credit " to PCRF by PCEF, now PCRF can think that request credit line is failed, and business is stopped.

For consumption limit service, be realized by extended credit management function and modified flow to an improvement project of prior art.Namely when OCS perceives business by limited time, not return " out of credit ", but again authorize for this business according to this instruction initiation IP-CAN session modification flow process request PCRF to PCEF, PCEF by carrying instruction (such as: new parameter identification).PCRF will reformulate or revise PCC rule for this restricted service, and be handed down to PCEF.PCEF performs new rule, and to OCS letter of application quota.OCS issues corresponding credit quota according to new charging policy for consumption limit service, realizes credit management and control.

Summary of the invention

Prior art and improvement project cannot solve the scene of following consumption limit service.Because the high QoS consumption restriction quota that user contracts be for a certain class or all business (Service A and Service B belongs to consumption restriction signing service, Service C does not belong to), and these business have identical or different charging rate RG(Service A, RG1; Service B, RG2; Service C, RG1), the credit mechanism of control of OCS is to issue credit quota for RG.Then when user has multiple business to use (Service A simultaneously, B, C), and some business belongs to the signing business (Service A and B) of consumption restriction, some is not (Service C), then OCS receives the CCR credit line request of RG1, then cannot determine whether as consumption restriction signing service Service A or non-consumption restriction signing service Service C, thus cannot make decision-making and the mandate of correct credit quota.

Embodiment

Basic thought of the present invention is, is sent the message of carrying the business information (such as service identification Service ID) of customer service, thus make OCS according to business information differentiated service by PCEF or PCRF to OCS, performs diameter credit control.

Concrete, for framework 1, can comprise the steps:

PCEF sends credit control request information to OCS, carries charge information (such as rating keys Charging key or rate group Rating Group) and the business information (such as service identification Service ID) of customer service;

Described OCS is that described customer service performs diameter credit control according to the charge information received and business information.

Wherein, OCS according to the charge information received and business information, can obtain local accounting-related information (the credit quota under the corresponding rate of such as this business), performs credit authorization.

OCS detect described customer service contracted consumption restriction time, can be specifically following four kinds of situations for described customer service performs diameter credit control:

(1 works as described OCS judges to there is available credit quota according to the described charge information received and business information, and meet mandate requirement (such as, with signing, the charge information (rate group or rating keys) received consumes that to limit the charge information (rate group or rating keys) used consistent) time, return Credit Control Answer message to described PCEF, carry the credit quota issued;

(2) when described OCS judges to there is available credit quota according to the described charge information received and business information, but do not meet to authorize and require (such as, with signing, the charge information (rate group or rating keys) received consumes that to limit the charge information (rate group or rating keys) used inconsistent) time, return Credit Control Answer message to described PCEF, carry analog threshold and arrive instruction;

(3) when described OCS judges to there is useless credit quota according to the described charge information received and business information, return Credit Control Answer message to described PCEF, carry refusal instruction and Reason For Denial value;

(4), when OCS is according to the described charge information received and business information, when detecting that described customer service arrives consumption threshold limit, send to described PCEF and carry Credit Control Answer message or the re-authorization request message that threshold value arrives instruction.

Wherein, trigger PCEF in above-mentioned (2) and initiate subsequent session modification process, upgrade PCC rule, that is: PCEF arrives instruction according to described analog threshold and initiates IP-CAN session modification flow process to PCRF, described PCRF is that PCC rule is reformulated or revised to described customer service, and is handed down to PCEF; PCEF performs the PCC rule that described PCRF issues, and resends credit control request information to OCS, carries charge information and the business information of customer service.

Trigger PCEF in above-mentioned (4) and initiate subsequent session modification process, upgrade PCC rule, that is: PCEF arrives instruction according to described threshold value and initiates IP-CAN session modification flow process to PCRF, and described PCRF is that PCC rule is reformulated or revised to described customer service, and is handed down to PCEF; PCEF performs the PCC rule that described PCRF issues, and resends credit control request information to OCS, carries charge information and the business information of customer service.

For framework 2, owing to having Sy interface between PCRF and OCS, thus between PCRF and OCS can between communication, specifically can comprise the steps:

PCRF sends charging policy conversation establishing message to OCS, carries the business information (such as service identification Service ID) of customer service;

OCS is that described customer service performs diameter credit control according to the business information received.

Particularly, above-mentioned PCRF normally carries out to OCS transmission charging policy conversation establishing message in IP-CAN session establishment process.

This charging policy conversation establishing message is the message that the present invention proposes, and it can be specifically credit control request information or re-authorization request message.

OCS is that described customer service execution diameter credit control specifically refers to according to the business information received: OCS returns charging policy response message to described PCRF, carry accounting-related information (include but not limited to consume the signing instruction of limit service, such as analog threshold arrives instruction or consumption limit service mark etc.).

After returning the charging policy response message of carrying accounting-related information to described PCRF at OCS, can comprise the steps: further

PCRF formulates corresponding PCC rule (such as special QoS guarantee (promote or reduce QoS), special rate (special Charging key or Rating Group)) according to described accounting-related information, and is handed down to PCEF;

PCEF performs the PCC rule that described PCRF issues, and sends credit control request information, carry charge information (such as rating keys Charging key or rate group Rating Group) and the business information of described customer service to OCS;

After described OCS receives described credit control request information, be that described customer service performs diameter credit control according to the described charge information received and described business information.

Described OCS detects that described customer service has been contracted consumption restriction, is that to perform diameter credit control can be specifically following four kinds of situations to described customer service according to the charge information received and business information:

(1) when described OCS judges to there is available credit quota according to the described charge information received and business information, and meet mandate requirement (such as, with signing, the charge information (rate group or rating keys) received consumes that to limit the charge information (rate group or rating keys) used consistent) time, return Credit Control Answer message to described PCEF, carry the credit quota issued;

(2) when described OCS judges to there is available credit quota according to the described charge information received and business information, but do not meet to authorize and require (such as, with signing, the charge information (rate group or rating keys) received consume that limit the charge information (rate group or rating keys) used inconsistent) time, send to described PCRF and carry the charging policy that analog threshold arrives instruction and report or return the Credit Control Answer message of carrying analog threshold arrival and indicating to described PCEF;

(3) when described OCS judges to there is useless credit quota according to the described charge information received and business information, return Credit Control Answer message to described PCEF, carry refusal instruction and Reason For Denial value;

(4) when described OCS is according to the described charge information received and business information, when detecting that described customer service arrives consumption threshold limit, send to described PCRF and carry the charging policy report that threshold value arrives instruction, or carry to described PCEF transmission Credit Control Answer message or the re-authorization request message that threshold value arrives instruction.

Wherein, for (2), OCS sends to described PCRF and carries after analog threshold arrives the charging policy report of instruction, can perform further:

PCRF arrives instruction according to described analog threshold and formulates corresponding PCC rule (such as special QoS guarantee (promote or reduce QoS), special rate (special Charging key or Rating Group)), and is handed down to PCEF; PCEF performs the PCC rule that described PCRF issues, and sends credit control request information, carry charge information (such as rating keys Charging key or rate group Rating Group) and the business information of described customer service to OCS.

For (2), OCS sends to described PCEF and carries the Credit Control Answer message that analog threshold arrives instruction, catches up with the flow process stating framework 1 the same, repeats no more herein.

For (3), when OCS detects that described customer service arrives consumption threshold limit, charging policy report can be initiated directly to PCRF, directly trigger PCRF and initiate IP-CAN session modification, comprise the steps: when described OCS detects that described customer service arrives consumption threshold limit, send to described PCRF and carry the charging policy report that threshold value arrives instruction, described PCRF is designated as described customer service according to described threshold value arrival and reformulates or revise PCC rule, and is handed down to PCEF; PCEF performs the PCC rule that described PCRF issues, and resends credit control request information to OCS, carries charge information and the business information of customer service.

Or, also can method as described in framework 1, send to PCEF to described PCEF and carry diameter credit control response message or the re-authorization request message that threshold value arrives instruction, trigger IP-CAN session modification.

For the ease of setting forth the present invention, be described in further detail below with reference to the enforcement of drawings and the specific embodiments to technical solution of the present invention.It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can combination in any mutually.

Fig. 2 and 3 is the flow chart of the present invention according to the embodiment of framework 1.Figure 4 and 5 are the flow chart of the present invention according to the embodiment two of framework 2.

Framework one

As shown in Figures 2 and 3, this flow process specifically describes as follows:

Step S201, IP-CAN conversation establishing completes, GW(PCEF) receive hPCRF(local PCRF) PCC that issues rule install execution.When there is BBERF, complete the establishment of gateway control session herein, BBERF receives QoS rule and performs simultaneously;

Step S202, GW(PCEF) send credit control request information to OCS, bring user ID, business information (as service identification ServiceID), charge information (as rate group Rating Group, rating keys Charging key);

The information that step S203, OCS receive according to OCS and this locality information stored of contracting carries out credit management and control.When OCS detects this service contracting of this user or this user consumption restriction, then give GW(PCEF) return Credit Control Answer message, carry user ID, business information (as service identification ServiceID) in message, and analog threshold arrives instruction.This analog threshold arrives instruction and is used to refer to GW(PCEF) the consumption restriction of this service contracting of this user or this user, need GW(PCEF) to hPCRF initiation session modification process, the QoS rule that please look for novelty, and carry out the process such as credit application and quota issue by new QoS rule;

Step S204, GW(PCEF) receive the Credit Control Answer message of OCS after, according to the analog threshold in message, trigger IP-CAN session modification flow process.Send CCR message rule for application to PCRF to upgrade, (namely OCS sends to GW (PCEF) to bring user ID, business information (as service identification Service ID) and analog threshold to arrive instruction in message.As required, other charge information (as rate group Rating Group) may be brought in message;

Step S205, hPCRF arrive instruction according to the threshold value in message after receiving the session modification request message that PCEF sends, and relevant business information, and other charge information that may simultaneously carry, and formulate new or amendment PCC/QoS rule.Such as, when judging the current use as consumption limit service, according to signing lifting or reduction QoS;

Step S206, PCRF issue IP-CAN session modification acknowledge message to GW(PCEF), bring the rule of the PCC/QoS after renewal in message; If there is GW(BBERF), PCRF will trigger gateway control session amendment, issue new QoS rule to GW(BBERF);

Step S207, GW(PCEF) receive after response message and install and implementation strategy.As Policy Updates, event trigger etc.;

Step S208, GW(PCEF) again initiate credit control request information to OCS.User ID is brought, business information (as service identification Service ID), charge information (as rate group Rating Group) in message;

Step S209, OCS according to the information received and this locality contract store information carry out credit management and control.When OCS detects this service contracting of this user or this user consumption restriction, and this charging policy to meet consumption restriction signing (such as, rate group is the particular value that consumption limits when contracting), then issue credit quota to GW(PCEF according to CAMEL-Subscription-Information) (such as, flow quota and/or time quota);

Step S210, PCEF receive the quota that OCS issues, and perform the consumption statistics of related service, business is normally carried out, and performs subsequent treatment by existing procedure.

UE achieves the signing of consumption limited subscriber business by step S201-step S210 and performs.In business procedure, when the consumption of GW (PCEF) add up (duration and or flow) reach the quota that OCS issues time, GW(PCEF) again can initiate credit control request to OCS, repeat S208 ~ S210 step, follow-up execution and the statistics of business are provided.Until signing consumption threshold limit arrives, will following steps be performed:

Step S301, in business procedure, GW(PCEF) threshold value arrival, initiate credit control request information to OCS, and report consumption;

Step S302 works as OCS and detects that consumption threshold limit arrives (as GW(PCEF) and reports notice or self timer expiry etc.), then can initiate re-authorization request, further triggering session modification process, upgrades PCC/QoS rule, performs corresponding diameter credit control and consumption statistics;

Step S303, OCS are to GW(PCEF) send Credit Control Answer message, bring user ID in message, business information (such as service identification Service ID), and threshold value arrives instruction (threshold value of namely consuming limit service arrives mark).As required, other charge information (as rate group Rating Group) may be brought in message;

Step S304, GW(PCEF) receive the Credit Control Answer message of OCS after, according to the threshold value in message, trigger IP-CAN session modification flow process.Send CCR message rule for application to hPCRF to upgrade, in message, bring user ID, business information (as service identification Service ID) and threshold value to arrive instruction.As required, other charge information (as rate group Rating Group) may be brought in message;

Step S305, hPCRF receive GW(PCEF) after the session modification request message that sends, arrive instruction according to the threshold value in message, and relevant business information, and other charge information that may simultaneously carry, formulate new or amendment PCC/QoS rule.Such as, when judge current as consumption limit service inactive time, according to signing reduction or promote QoS;

Step S306, PCRF issue IP-CAN session modification acknowledge message to GW(PCEF), bring the rule of the PCC/QoS after renewal in message; If there is GW(BBERF), PCRF will trigger gateway control session amendment, provide the rule of the QoS after renewal to GW(BBERF);

If threshold value instruction is not arrived instruction in Credit Control Answer message in step 303 to send to PCEF, then OCS can initiate a re-authorization request message, sends and is indicated to GW(PCEF accordingly).Then herein, GW(PCEF) send re-authorization response message to OCS, carry internal user mark in message, and operation instruction (in such as result code, indicating services continues and sends having new credit control request).If terminate business after signing consumption limit service threshold value arrives, then signing operation instruction is that service ending is then without follow-up credit request message.Then follow-up S307-310 no longer performs, and related network elements does session termination process by prior art, and flow process terminates.Otherwise continue S307 flow process;

Step S307, GW(PCEF) install and perform the strategy that hPCRF issues.As Policy Updates, event trigger etc.;

Step S308, GW(PCEF) again initiate credit control request information to OCS.User ID is brought, business information (as service identification Service ID), charge information (as rate group Rating Group) in message;

Step S309, OCS according to the information received and this locality contract store information carry out credit management and control.When OCS detects this service contracting of this user or this user consumption restriction, but consumption limit service threshold value arrives (consumption of such as stipulated time is finished using), and charging policy to meet non-consumption limit service signing (such as, rate group is different from the value of consumption restriction strategy), then issue credit quota to GW(PCERF according to CAMEL-Subscription-Information) (such as, flow quota and/or time quota);

Step S310, PCEF receive the quota that OCS issues, and perform the consumption statistics of related service, business is normally carried out, and performs subsequent treatment by existing procedure.

Above step S201 ~ S310, for the complete consumption limit service of framework 1 signing, authorize and perform, and threshold value arrive after cancellation and the flow process upgraded.

Embodiment two

Figure 4 and 5 are the flow chart of the present invention according to the embodiment two of framework 2,

This flow process specifically describes as follows:

Step S401, gateway control session has created, and the gateway that PCEF is positioned at receives IP-CAN session establishment request message, triggers IP-CAN conversation establishing flow process;

Step S402, GW(PCEF) receive IP-CAN carrying foundation request, the PDN carrying the PDN network of user ID and request access in this IP-CAN session establishment request message identifies;

Step S403, GW(PCEF) initiate the instruction of IP-CAN conversation establishing to hPCRF, and in this IP-CAN session establishment Indication message, carry user ID, PDN mark and the IP address (IP Address) for UE distribution;

Step S404, hPCRF also judge the subscription data of not this user according to user ID, then send signing document request to SPR, and in this signing document request, carry user ID and PDN mark;

Step S405, SPR return user signing contract information (that is, signing document response) according to user ID and PDN mark;

Step S406, what return as SPR signingly shows, the strategic decision-making of PCRF needs to depend on accounting-related information, and PCRF not yet obtains relevant information (such as this IP-CAN session is first IP-CAN session of this user and PDN), then need to initiate charging policy session.PCRF will send charging policy conversation establishing message to OCS, bring user ID, IP address in message, and business information (as service identification);

Step S407, OCS carry out local search and decision-making according to charging policy conversation establishing and this locality information stored of contracting, and send charging policy session and reply to hPCRF.Accounting-related information is brought in message.Such as, when OCS detects this service contracting of this user or this user consumption restriction, then in message except carrying user ID, business information (as service identification Service ID), also can bring corresponding signing instruction (such as consuming limit service mark or analog threshold etc.).This signing instruction is used to refer to this service contracting of this user of PCRF or this user consumption restriction, needs to formulate corresponding PCC/QoS rule to ensure the QoS of such user or such business;

Step S406 and step S407, need to trigger according to realization mechanism, at least can comprise following several executive mode: (now the associated billing information of all for this UE business can be sent to hPCRF by OCS) can be performed during first IP-CAN conversation establishing under this PDN of certain UE; Can perform when each IP-CAN conversation establishing of certain UE (now, PCRF can trigger the need of the charge information obtaining OCS according to the strategic decision-making of this business); Can perform when the session first of hPCRF and this OCS that (this type of scene is such as that whole UE and business List contracts when certain class charge information, then once can be handed down to hPCRF and do local storage and follow-up local IP access.Such charge information of OCS upgrades rear notice hPCRF and upgrades.); Can in the IP-CAN session modification process of certain UE, strategic decision-making needs to obtain this machine charge information, and triggers the charging policy session of execution and OCS;

Step S408, after hPCRF receives the charging policy session response message of OCS, according to the signing instruction (such as consuming limit service mark or analog threshold etc.) in message, and other CAMEL-Subscription-Information returned, network strategy, UE access information etc. generate strategy (comprising PCC rule, event trigger etc.).When judging the current use as consuming limit service, then can formulate special PCC/QoS rule (as special QoS can be provided to ensure, authorizing special Charging key or Rating Group etc.);

Step S409, hPCRF are to GW(PCEF) return IP-CAN session establishment acknowledge message, issue the strategy of formulation;

Step S410, GW(PCEF) receive after response message and install and implementation strategy, as PCC rule, event trigger etc.And initiate credit control request information according to authorization rule to OCS.User ID is brought, business information (as service identification Service ID), charge information (as rate group Rating Group) in message;

Step S411, OCS according to the information received and this locality contract store information carry out credit management and control.When OCS detects this service contracting of this user or this user consumption restriction, and this charging policy to meet consumption restriction signing (such as, rate group is the particular value that consumption limits when contracting), then issue credit quota to GW(PCERF according to CAMEL-Subscription-Information) (such as, flow quota and/or time quota);

Step S412-415, performs subsequent treatment by existing process ends.GW(PCEF) place gateway returns carrying and sets up response (S412), carries the IP address of distribution.If needed, corresponding load creating process (S413 and S414) may be initiated and set up IP-CAN session response.According to the consumption statistics of the quota execution related service that OCS issues, business is normally carried out.

UE achieves the signing of consumption limited subscriber business by step S401-step S415 and performs.In business procedure, when the consumption of GW (PCEF) add up (duration and or flow) reach the quota that OCS issues time, GW(PCEF) again can initiate credit control request to OCS, repeat S410 ~ S411 step, provide new credit quota to continue the follow-up execution of business.Until signing consumption threshold limit arrives, triggering session modification process.

As shown in Fig. 1 (b) framework, OCS, by Sy interface and PCRF direct interaction (as Fig. 5), triggers re-authorization, and initiation session amendment Sum fanction upgrades.Or by Gy interface and GW(PCEF) mutual, initiate re-authorization and session modification flow process.Below then implement to describe respectively to this two class.

If Fig. 5, OCS are by Sy interface and PCRF direct interaction, its execution step is:

Step S501, in business procedure, when OCS detects that consumption threshold limit arrives (such as GW(PCEF) and reports notice or self timer expiry etc.), then can initiate re-authorization request, further triggering session modification process, upgrade PCC/QoS rule, perform corresponding diameter credit control and consumption statistics;

Step S502, OCS send charging policy report to PCRF.Bring user ID in message, business information (such as service identification Service ID), and threshold value arrives instruction (threshold value of namely consuming limit service arrives mark).As required, other charge information (as rate group Rating Group) may be brought in message;

After step S503, PCRF receive charging policy report, return charging policy report response to OCS.User ID is carried in message, and operation instruction (in such as result code, indicating services continues and sends having new credit control request).If terminate business after signing consumption limit service threshold value arrives, then signing operation instruction is that service ending is then without follow-up credit request message.Then follow-up flow process will no longer perform, and related network elements does session termination process by prior art, and flow process terminates.Otherwise continue S504 flow process;

Step S504, hPCRF arrive instruction according to the threshold value in charging policy report, and relevant business information, and other charge information that may simultaneously carry, and adjust and upgrade PCC/QoS rule.Such as, when judge current as consumption limit service inactive time, according to signing reduction or promote QoS;

Step S505, PCRF issue PCC/QoS rule and provide message to GW(PCEF) bring the PCC/QoS rule after renewal in message; If there is GW(BBERF), PCRF will trigger gateway control session amendment, provide the rule of the QoS after renewal to GW(BBERF);

Step S506, GW(PCEF) receive after rule provides message and install and implementation strategy renewal, as PCC rule, event trigger etc.

Step S507, GW(PCEF) again initiate credit control request information to OCS.User ID is brought, business information (as service identification Service ID), charge information (as rate group Rating Group) in message;

Step S508, OCS according to the information received and this locality contract store information carry out credit management and control.When OCS detects this service contracting of this user or this user consumption restriction, but consumption limit service threshold value arrives (consumption of such as stipulated time is finished using), and charging policy to meet non-consumption limit service signing (such as, rate group is different from the value of consumption restriction strategy), then issue credit quota to GW(PCERF according to CAMEL-Subscription-Information) (such as, flow quota and/or time quota);

Step S509, GW(PCEF) return rule to hPCRF response message is provided;

Step S510, GW(PCEF) receive the quota that OCS issues, perform the consumption statistics of related service, business is normally carried out, and performs subsequent treatment by existing procedure.

The consumption limit service that above step S401 ~ S415 and S501 ~ S510 structure composed 2 is complete signing, authorize and perform, and threshold value arrive after cancellation and the flow process upgraded.

As Fig. 3, in framework 2, OCS is by Gy interface and GW(PCEF) mutual, upgrade handling process and the step of the amendment of threshold value initiation session, identical with framework 1, see step S301 ~ S310.The consumption limit service of then step S401 ~ S415 and S301 ~ S310 structure composed 2 signing, authorize and perform, and threshold value arrive after cancellation and upgrade another complete flow process.

In the improvement project of prior art, OCS is that analog threshold arrives situation to the new parameter identification that PCEF returns, and triggering session amendment upgrades dependency rule, has reused the existing flow process realizing framework.There is redundancy message and the process such as the mutual and session modification flow process of discrimination weight.The embodiment of the present invention two overcomes above-mentioned defect.
