PDN, is the IP operation network of operator, and this network is served for user provides IP by the core net of operator.
In addition, policy control and charging control function (PCC, Policy and Charging Control) embed in EPS framework, in EPS framework, the each functional entity of PCC can distribute as follows: PCRF is "Policy and Charging Rules Function entity, strategy and charging execution function entity (PCEF, Policy and Charging Enforcement Function) be present in P-GW, bearing binding and event reporting function entity (BBERF, Bearer Binding and Event Report Function) can be present in S-GW, Application Function (the AF of business, Application Function) be present in the IP operation network of operator, user-subscribed database (SPR, Subscription Profile Repository) can unify with HSS.
In 3GPP, can find corresponding PDN network by APN (APN, Access Point Name).Conventionally UE is called to an IP to a connection of PDN network and connects Access Network (IP-CAN, IP Connectivity AccessNetwork) session.PCC is applicable to all 3GPP IP-CAN, its framework is (Fig. 2 is according to the non-roaming composition structural representation of the PCC of correlation technique) as shown in Figure 2, PCRF is mainly responsible for the formulation of strategy and charging regulation, by Gx interface, PCC strategy and the charging regulation of formulation are handed down to PCEF, PCEF installs, carries out PCC strategy, and report dependent event, with the mutual charge information of charge system.
PCRF is handed down to BBERF by Gxx interface by QoS (QoS, Quality ofService) rule, the mutual charge information of BBERF discord charge system, only reporting of responsible bearing binding and dependent event.AF provides business information by Rx interface to PCRF, and SPR has preserved the signing business information of user, and PCRF can be by Sp interface to the signing business information of SPR inquiring user.PCEF sends to Online Charging System (OCS by Gy interface by online charging information, Online ChargingSystem) be responsible for the statistics of online charging, by Gz interface, offline charging information is sent to off-line accounting system (OFCS, Offline Charging System).
At present, in PCC framework, PCRF can dynamically issue PCC strategy to PCEF, comprises the information of QoS and charging in policy information.The signing business information of user in the service related information that PCRF provides according to AF, the bearer related information that PCEF reports and SPR, formulates PCC strategy.
AF, for the access point of service application is provided, the Internet resources that these service application are used need to carry out dynamic policy control.In the time that service surface is carried out parameter negotiation, related service information is passed to PCRF by AF.If these business information are consistent with the strategy of PCRF, PCRF accepts this negotiation; Otherwise PCRF refuses this negotiation, and in the time of feedback, provide the acceptable service parameter of PCRF.Subsequently, AF can return to these parameters subscriber equipment (UE, User Equipment).Wherein, the interface between AF and PCRF is Rx interface.
PCRF is the core of PCC, for being responsible for the formulation of strategic decision-making and charging regulation.PCRF provides the rule of the network control based on business data flow, these network controls comprise detection, gate (Gating Control), service quality (QoS, Quality of Service) control and the charging regulation based on data flow etc. of business data flow.PCRF sends to PCEF to carry out the strategy of its formulation and charging regulation; Meanwhile, PCRF also needs to guarantee that these rules are consistent with user's CAMEL-Subscription-Information.Wherein, PCRF generate strategy with charging regulation according to comprising: that obtain from AF and information traffic aided, that obtain from SPR and relevant with charging with policy control user policy, billing control and subscription information and that obtain from PCEF by Gx interface and information carrying network of relation.
PCEF is usually located in gateway (GW, Gate-Way), carries out at loading end strategy and the charging regulation that PCRF formulates.Business datum flow filter in the rule that PCEF sends according to PCRF detects business data flow, and then these business data flows are carried out to strategy and the charging regulation that PCRF formulates; In the time that carrying is set up, the rule that PCEF sends according to PCRF is carried out resource distribution, and the information providing according to AF is carried out gate control; Meanwhile, the Event triggered that PCEF subscribes to according to PCRF reports event on bearer network; The charging regulation sending according to PCRF, PCEF carries out corresponding service data flow charge operation, and charging can be both online charging, can be also offline charging.If online charging, PCEF needs and Online Charging System (OCS, Online Charging System) carry out credit management together; When offline charging, the charge information of exchange correlation between PCEF and off-line accounting system (OFCS, Offline Charging System).Wherein, the interface between PCEF and PCRF is Gx interface, and the interface between PCEF and OCS is Gy interface, and the interface between PCEF and OFCS is Gz interface.PCEF also can strengthen and has business measuring ability (TDF, Traffic Detection Function).The ADC rule that application that what PCEF can issue according to this locality configuration or PCRF comprise detects control strategy (ADC, Application Detection and Control) apply and is detected and carry out strategy execution (as gate, redirected and limit bandwidth).PCEF is generally positioned on the gateway of network, as the grouped data network gateway of EPS (PDN-GW), GPRS (GPRS, GeneralPacket Radio Service) in GGSN (GGSN) and interconnected wireless network local area network (LAN) (I-WLAN, Interworking WLAN) in packet data gateway (PDG, Packet Data Gateway) etc.

It is a packet data network (PDN of access that above PCC framework has been realized UE by each functional entity, Packet DataNetwork) IP that sets up connects the policy and charging control of Access Network (IP-CAN, IP Connectivity Access Network) session.
In prior art, in the time that user roams into visited place, there are two kinds of modes, one is ownership place route access (home routedaccess), one is local break-out access (local breakout access), local break-out access scene is as shown in Fig. 3 (Fig. 3 is the PCC roaming visited place access architecture schematic diagram according to correlation technique), PCEF is positioned at visited network, and the information interaction of visited network and home network is by visited network PCRF(V-PCRF) and home network PCRF(H-PCRF) between the transmission of roaming interface S9 interface.When user is in the time that access zone network accesses, VPCRF sets up S9 session/sub-session by S9 interface requests, and HPCRF formulates PCC strategy, issues PCC rule to VPCRF, and forward pass is to execution such as PCEF/BBERF.
At present, the individual business Requirement Increases of mobile communication, there is larger difference in the type of service of different operators, the rate that when user roams simultaneously, home network business is used in roaming place are higher, these two reasons cause user to roam into visited network needs when can being supported in access belonging area network business, can access by it local service (being called roaming local service) of visited network at the signing terminal of home network and id information, so not only can farthest strengthen user's experience and reduce rate, the characteristic service of the not available access zone network of its home operator network also can be provided for user simultaneously.
Because roaming local service belongs to access zone network, is independently with respect to the signing of home network, therefore, access corresponding strategies and the resource authorization of roaming local service function for user, need to be by access zone network VPCRF decision-making.And this user belongs to belonging area network, its rate account is at belonging area network OCS.Because roaming local service belongs to access zone network, contracting for home network, independently (belonging area network not necessarily has such business, or such business having but its to identify two zone networks also inconsistent), therefore such business information belonging area network OCS None-identified, cannot carry out to roaming local service the processing such as credit authorization of online charging.
In prior art, user roams into after access zone network, can only carry out online charging function by ownership place OCS, can pass through visited place network element (for example proxy OCS) interface to ownership place OCS, or can, by visited place VPCRF forward pass credit request to ownership place HPCRF, forward to OCS and carry out.But these methods of prior art all can only be for ownership place signing service, ownership place PCRF or OCS can get business and the rate CAMEL-Subscription-Information of ownership place.And for roaming local service, home network does not probably have the signing of related service, therefore cannot realize the online charging function to roaming local service by the kinds of schemes of prior art.
In addition, a kind of scheme of solution that prior art provides roaming local service is, roamer is signing and open roaming rate account to visited network, and these rate OCS(that account leaves visited network in that contracts is V-OCS).Visited network OCS(is V-OCS) can directly carry out account credit and management of balance to roamer according to this visited network is signing, implement credit control, and be not H-OCS to home network OCS() control of request credit.But the problem that this technical scheme exists is, user need to be in roaming place paying again, a large amount of remaining sums in original ownership place account cannot be used.And user leaves after this roaming place network, also need to settle accounts this roaming place expense, become bad accounts amount otherwise will be trapped in this roaming place holding account.Bring therefore to user's the use of roaming local service and be much equal to the processing of roaming local new account, grievous injury roaming local service make every effort to the principle to the business experience of the more convenient abundant and high-quality of user, and fail the substantive online charging problem that solves roaming local service.
For the problem of online charging function that cannot realize better access zone network in correlation technique and carry out roaming local service, effective solution is not yet proposed at present.

Preferably, send to V-OCS in credit threshold is carried at credit threshold response message by H-OCS in, H-OCS can also send to V-OCS by authorizing credit management indication to be carried in credit threshold response message, wherein, authorize credit management indication to carry out the credit management of online charging for informing V-OCS.
Please refer to Fig. 5, Fig. 5 is the PCC roaming visited place access architecture schematic diagram according to the embodiment of the present invention, the charging policy method of the roaming local service that in actual applications, the present embodiment provides can realize by the PCC roaming visited place access architecture shown in Fig. 5 completely.In the access architecture of PCC roaming visited place, visited network can be realized the online charging function of roamer being carried out to roaming local service, can use the roaming local service of online charging while making user roam into visited network.Compared with the PCC roaming visited place access architecture shown in Fig. 3, in the PCC roaming visited place access architecture shown in Fig. 5, visited place PCEF and visited place OCS are by Gy interactive interfacing, visited place OCS and ownership place OCS increase interface (for example diameter agreement) newly, realize the credit threshold mandate of ownership place OCS to visited place OCS, carried out the online charging credit management of roaming local service by visited place OCS.According to the framework shown in Fig. 5, can easily realize conversation establishing, modification and the termination flow processing of roaming local service.
Particularly, under roaming visited place access scene, when (visited place OCS receives the request of online charging session activation, create the credit control request information of IP-CAN), first visited place OCS judges whether the business that credit control request information is asked belongs to roaming local service, if threshold value request is sent and (can pass through agent way proxy or redirected mode redirect, be generally proxy; Threshold value request can send by credit threshold request message) to ownership place OCS.
Receiving after this online charging session activation request, whether ownership place OCS can be also that the legitimacy of roaming local service (or whether this user can authorize roaming local service) judges to the business of this request correspondence, if roaming local service (maybe can authorize the user of roaming local service), just be necessary to carry out further threshold value authorisation process, that is: send online chargeable session and activate response (credit control response message) to visited place OCS, ownership place OCS(is according to roaming agreement or approval authority of contract signature) in this corresponding message, (for example comprise credit threshold, can be the account amount of money, or the consumption such as time flow event) give visited place OCS.Otherwise ownership place OCS sends response message to visited place OCS, refuses this threshold value request.Then, online charging session activation response (being credit control response message) is sent to PCEF by visited place OCS, and wherein, the response of online charging session activation carries the credit line of this requested service.
In actual applications, the credit control request information that visited place OCS receives and be transmitted in the credit request message of ownership place OCS and can carry from the service related information of this request and can comprise: (this two be only that form is different for roaming local service mark or indication roaming local service mark, role is identical), or the authorization message that can carry this user in credit request message can be roaming local service mandate indication.And then ownership place OCS can judge that user's roaming local service authority carrys out decision-making and whether give active user a credit threshold mandate according to this information.
In actual applications, the credit threshold that ownership place OCS distributes to visited place OCS can be account amount of money threshold value or the flow threshold of this user's some, or time threshold, or event threshold etc., further, the threshold value that visited place OCS can authorize according to this ownership place OCS is carried out the operation such as credit management of the prior art and the processing of the account amount of money.
In addition, in business procedure, (the also account amount of money, flow in the time that the credit threshold of visited place OCS arrives, or the state that is finished of time, or the state that finishes of event), visited place OCS can send a request message again to ownership place OCS, again asks credit threshold, and the flow process that relevant treatment flow process issues threshold value with request is first identical.
And when last the roaming local service under this user's same APN finishes, visited place OCS will send online chargeable session ending message to ownership place OCS, report the use consumption (amount of money of visited place, flow, the time, or event etc.) and/or remain consumption to ownership place OCS.
The charging policy method of roaming local service above-described embodiment being provided below in conjunction with Fig. 6, Fig. 7 and preferred embodiment is further described, to better understand embodiments of the invention.
The visioning procedure figure of IP-CAN session when Fig. 6 is UE roaming according to the preferred embodiment of the invention, as shown in Figure 6, this flow process comprises the following steps (step S602-step S630):
Step S602, sets up in the process of IP-CAN session in UE request, and the gateway that PCEF is positioned at receives IP-CAN session establishment request message, and in this IP-CAN session establishment request message, carries the PDN mark of the PDN network of user ID and request access;
Step S604, PCEF sends IP-CAN session establishment Indication message to V-PCRF, and in this IP-CAN session establishment Indication message, carries user ID, PDN mark and the IP address (IP Address) for UE distribution;
When UE access visited network, visited network provides ownership place roaming scheme and roaming local service scheme, and UE has selected roaming local service scheme; PCEF sends local the roaming of UE scheme indication to VPCRF in message;
Step S606, V-PCRF judges that according to user ID this user is roamer.If PCRF is not also for this user sets up S9 session, V-PCRF sends a request message to H-PCRF, and to set up S9 session, also a S9 session is set up in request simultaneously, V-PCRF carries also this user's CAMEL-Subscription-Information not of user in S9 session, PDN mark and IP address etc.If PCRF is for this user has set up S9 session, V-PCRF sends a request message to H-PCRF, and to revise S9 session, also a S9 session is set up in request simultaneously, V-PCRF carries also this user's CAMEL-Subscription-Information not of user in S9 session, PDN mark and IP address etc.;
VPCRF supports roaming local service function, in the support feature carrying in this CCR request message, RLS(roaming local service is set) function; If this function is not essential function, except support feature capability negotiation, VPCRF need to send request the mandate of asking this roaming local service to HPCRF; Concrete request mode does not limit, for example, in this CCR message, carry RLS requestAVP to HPCRF etc.;
Step S608, H-PCRF also judges not this user's subscription data according to user ID, H-PCRF sends signing document request to SPR, and in this signing document request, carries user ID and PDN mark;
Step S610, SPR returns to user signing contract information (, signing document is replied) according to user ID and PDN mark;
If now ownership place SPR did not also provide the roaming local service document of contracting to H-PCRF, so now SPR will provide to H-PCRF.
Or H-PCRF is just mutual to obtain the signing document of roaming local service with SPR after device start.
Step S612, H-PCRF is according to the request message of VPCRF, and the judgement such as the access information of the user signing contract information returning, network strategy, UE authorizes roaming local service, or formulates distributing policy:
If HPCRF is according to the information such as CAMEL-Subscription-Information and roaming agreement, authorize the roaming local service function of visited place, return to response message to VPCRF, in message, may comprise and represent that support feature, the HPCRF of this function support authorize the details such as indication and the list of mandate operator that may exist and the business of mandate list to the RLS of VPCRF.Mandate VPCRF can be to roaming local service independent resource mandate and policy development (such as user class mandate);
If HPCRF does not support to roam local service, or support but do not authorize the roaming local service of visited network to this user, HPCRF returns to corresponding support feature indication, and the indication that whether allows RLS that may exist (for example RLS report or reject, or directly refuse this message, carry relevant reject cause); If desired HPCRF formulates corresponding strategies, and strategy comprises PCC rule, event trigger etc., carries the strategy of formulation in the message that H-PCRF returns to V-PCRF;
Step S614, the message that V-PCRF storage HPCRF returns.According to authorizing roaming local service or PCC rule, return to corresponding response message to PCEF.If the strategy that HPCRF formulates is as prior art flow performing rule issues.If HPCRF authorizes V-PCRF to carry out roaming local service function, VPCRF formulates this traffic aided PCC rule and is handed down to PCEF, and corresponding QoS rule issues each BBERF, installs and carries out;
Step S616, if online charging PCEF will activate online charging session.Provide relevant input message to visited place OCS and ownership place OCS decision-making.Owing to being roaming local service, PCEF sends credit control request information to visited place OCS.
Step S618, visited place OCS judges that this business, for roaming local service, needs to ask to ownership place OCS the overall credit threshold of whole or such business of this user.
Step S620, this request message of visited place OCS forward pass (adopt proxy or redirect mode, be generally proxy), to ownership place OCS, carries roaming local service mark or indication information in this message.
Step S622, ownership place OCS (for example judges whether to meet authorising conditional, can judge that this business is for roaming local service according to the services of roaming indication in message or mark, judge whether to authorize such business according to roaming agreement or signing accounts information), send response message to visited place OCS.Authorize whole credit threshold if meet authorising conditional, carry to access zone network VOCS in response message, this threshold value can be the consumptions such as the account amount of money, or time flow event.In actual applications, when ownership place OCS authorizes visited place OCS credit threshold, can also send to the mandate credit management indication of visited place OCS, this mandate credit management knowledge is carried out the credit management of online charging for informing visited place OCS, or ownership place OCS only authorizes credit threshold to visited place OCS, implicit expression informs that visited place OCS carries out the credit management of online charging.
Step S624, VOCS is according to the business information of PCEF credit request and ownership place mandate and the threshold value that issues, carry out credit authorization, issue corresponding credit quota to PCEF, concrete technical finesse is similar to the credit management flow process of ownership place and OCS and the ownership place PCEF of prior art.
Step S626, PCEF installs and implementation strategy.As PCC rule, event trigger etc.PCEF place gateway is set up IP-CAN session to returning to reply, and carries the IP address of distribution;
Step S628, in business procedure, the credit line that visited place OCS is handed down to PCEF is used up, and business continues, PCEF continues to send credit control request information to visited place OCS application credit line, and in request message, reports current use consumption;
Step S630, visited place OCS stores current use consumption, and total threshold value of authorizing according to ownership place OCS, judges whether the credit line of authorizing PCEF new.Send response message to PCEF, carry the credit line of new mandate.The credit management interaction flow of PCEF and visited place V-OCS in the visited network of step S628 and step S630, the credit management that can use for reference ownership place PCEF and ownership place OCS in existing home network.
Wherein, if ownership place OCS licenses to, total credit threshold of visited place arrives and service needed continues, and visited place OCS can send a request message again to ownership place OCS, again asks the total threshold value of credit, and carries current actual use consumption to ownership place OCS; Relevant treatment flow process asks to authorize the processing of total threshold value first with step S620 and step S622.
Through above-mentioned flow process, can carry out the online charging function of roaming local service.In the time of conversation end, (granularity can be last the IP-CAN session under each IP-CAN session or this APN, specifically determine according to carrier policy), the threshold value residue consumption (and/or current use consumption) that ownership place OCS licenses to visited place OCS need to report to ownership place OCS, PCEF will send credit final report and initiate credit session termination to visited place OCS, and idiographic flow is described as shown in Figure 7.
Please refer to Fig. 7, the termination flow chart of IP-CAN session when Fig. 7 is UE roaming according to the preferred embodiment of the invention, as shown in Figure 7, this flow process comprises the following steps (step S702-step S730):
Step S702, PCEF detects the triggering IP-CAN session that need to terminate, this triggering may be from other network elements, UE or PCEF self (for example PCC rule is all deleted);
Step S704, PCEF sends IP-CAN session termination Indication message to VPCRF; Inform that this IP-CAN session of VPCRF is just deleted, and provide relevant information to VPCRF;
Step S706, the relevant PCC rule of roaming local service in this IP-CAN session is generated by VPCRF, receives after this session termination request VPCRF by identification and deletes this rule-like and relevant information thereof;
Step S708, if this IP-CAN session exists corresponding S9 session or son reply, VPCRF is the termination request of forward to HPCRF(by transmission S9 session modification or termination request message), the termination of this IP-CAN session of notice HPCRF.If this IP-CAN session is last the IP-CAN session under this APN, the S9 session that terminates, otherwise revise S9 session, sub-session corresponding to this IP-CAN session terminates;
Step S710, HPCRF will identify and delete the PCC rule that this IP-CAN is relevant, and deletes the information that this IP-CAN session is relevant, such as CAMEL-Subscription-Information etc.;
Step S712, PCEF deletes all PCC rules that this IP-CAN is relevant;
Step S714, HPCRF sends the corresponding message of S9 session modification or termination to VPCRF;
Step S716, VPCRF sends IP-CAN session termination response message to PCEF, informs the finalization process of this IP-CAN session.This message is the response message of step S704;
Step S718, for the roaming local service of online charging, PCEF sends final report to visited place OCS, and carries residue credit (and/or current use consumption) to visited place OCS;
Step S720, visited place OCS judges this business for roaming local service, residue credit (and/or using consumption) corresponding to credit threshold that need to authorize to ownership place OCS report ownership place OCS;
Step S722, visited place OCS sends credit final report to ownership place OCS, carries residue credit (and/or using consumption) corresponding to credit threshold that ownership place OCS authorizes in message, and informs the termination of this credit;
Step S724, ownership place OCS stores this residue credit, sends response message to visited place OCS; If existed, online chargeable session terminates;
Step S726, visited place OCS sends credit final response message to PCEF, and this online charging session that terminates.
In addition, carry out in process in business, when IP-CAN session modification occurs, change if relate to charge information, may trigger PCEF and will initiate credit request or send final report request to visited place OCS; Concrete PCEF and visited place OCS, and the interaction process flow process of ownership place OCS is with the credit management flow process in Fig. 6 and Fig. 7.Relate to charging relevant treatment flow process identical, be not repeated in this description here.
