Description
Technical field
The present invention relates to the communications field, in particular to a kind of method for processing business.
Background technology
Third generation partner program (3rdGenerationPartnershipProject, referred to as 3GPP) strategy and charging control (PolicyandChargingControl, referred to as PCC) framework is a functional framework that can be applied to multiple access technology, such as, it can be applied to universal mobile telecommunications system (UniversalMobileTelecommunicationsSystem, referred to as UMTS) terrestrial radio access network (UMTSTerrestrialRadioAccessNetwork, referred to as UTRAN), global system for mobile communications (GlobalsystemforMobileCommunication, referred to as GSM)/GSM data enhancing evolution (EnhancedDataratesforGlobalEvolution, referred to as EDGE) wireless access network, grouping system (the EvolvedPacketSystem of intercommunicated wireless local area network (I-WLAN) and evolution, referred to as EPS) etc.
Fig. 1 is according to the non-roaming Organization Chart of the PCC of correlation technique, is described each logical functional entity in PCC framework and interface function thereof referring to Fig. 1:
Application Function (ApplicationFunction, 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 policy control and charging regulation function entity (PolicyandChargingRulesFunction, referred to as PCRF) by AF.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 (UserEquipment, 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 detection of business data flow, gate (GatingControl), service quality (QualityofService, 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 (PolicyandControlEnforcementFunction, 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; Obtain and user policy, billing control and subscription information from user-subscribed database (SubscriptionProfileRepository, referred to as SPR); The information with carrying network of relation is obtained from PCEF.
PCEF is usually located in gateway (Gate-Way, referred to as GW), performs the strategy formulated of PCRF and charging regulation at loading end.Business datum flow filter in the rule that PCEF sends according to PCRF detects business data flow, and then performs to these business data flows the strategy and charging regulation that PCRF formulates.When carrying is set up, PCEF carries out service quality (QualityofService, referred to as QoS) according to the rule that PCRF sends and authorizes, 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 (OnlineChargingSystem, referred to as OCS) carry out credit management together.During offline charging, exchange correlation charge information between PCEF and off-line accounting system (OfflineChargingSystem, 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 generally positioned on the gateway of network, such as, and the GGSN (GGSN) in GPRS and the packet data gateway (PacketDataGateway, referred to as PDG) in I-WLAN.
Bearing binding and event reporting function entity (BearerBindingandEventReportingFunction, 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 (EvolvedPacketDataGateway, 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) and PCEF carry out the control and management of user credit under online charging mode together.
Off-line accounting system (OFCS) completes the billing operation under offline charging mode together with PCEF.
It is access packet data network (PacketDataNetwork that PCC framework achieves UE by above each functional entity, referred to as PDN) IP that sets up connects the policy and charging control of Access Network (IPConnectivityAccessNetwork, referred to as IP-CAN) session.
Adopt current PCC framework, there is following problem:
(1) information of business is provided by AF, and PCRF carries out strategic decision-making according to this information.And in existing network application, under a lot of scene, there is no AF.IP Multimedia System (IMSIPMultimediaSubsystem, referred to as IMS) etc. the business of dialogue-based class can adopt session initiation protocol signaling (SessionInitiationProtocol, referred to as SIP, SIP is the signaling control protocol of an application layer) operation layer that conversates consults (such as, code encoding/decoding mode, medium type, required bandwidth etc.), the notification of business information PCRF that P-CSCF (AF namely in PCC framework) will consult, and carry out QoS mandate by PCRF.And the business of a large amount of non-session class in existing network, such as, voice transfer (the VoiceOverInternetProtocol of current application IP based network, referred to as VoIP), IPTV (IPTVInternetProtocolTelevision, referred to as IPTV), video request program (Video-On-Demand, referred to as VOD), the business etc. such as online game can not carry out the media negotiation of application layer and business information is pushed to the process of PCRF.For these non-session class business, although can carry out certain policy authorization by configuring some static policies on PCRF, but this mode strongly limit the advantage of PCC framework.
(2) current, the filter wrapped for detecting IP in the PCC rule that PCRF issues is all adopt five-tuple (that is, source IP address, source port, object IP address, destination interface, protocol number).And under some scene, only adopt five-tuple can not two kinds of different traffic differentiation out, this just needs more than four layers (according to inventionthe open systems Interconnect Reference Model (OpenSystemInterconnectionReferenceModel, referred to as OSI), more than 4 layers is session layer, presentation layer and application layer) information detect.
In order to overcome the above problems, need to carry out function enhancing to existing PCC framework, introducing business measuring ability (TrafficDetectionFunction, referred to as TDF) is a kind of effective method.TDF has two kinds of implementations, and one is integrated by TDF and PCEF, and another kind is that TDF and PCEF divides out deployment.Because TDF needs the infomation detection carrying out more than 4 layers, if deployment integrated with PCEF, the performance of original PCEF equipment will be reduced greatly; If separately disposed, although little on the impact of PCEF equipment, greatly will improve the performance requirement of TDF, thus can expense be improved.For the compromise how realizing performance and price preferably, at present effective solution is not yet proposed.
