Description
Technical field
The present invention relates to the communications field, in particular to a kind of Access Network method for sending information and device.
Background technology
Fig. 1 is according to third generation partner program (3rdGenerationPartnershipProject in correlation technique, referred to as 3GPP) strategy that defines and charging control (PolicyandChargingControl, referred to as PCC) configuration diagram, as shown in Figure 1, "Policy and Charging Rules Function entity (PolicyandChargingRulesFunction, referred to as PCRF) use Internet resources to carry out the formulation of service quality (QualityofService, referred to as QoS) and charging policy for business.PCRF formulates control strategy to be needed to combine from application function (ApplicationFunction, referred to as AF) business information that receives, from user-subscribed database (SubscriptionProfileRepository, referred to as SPR) user signing contract information that receives, the strategy etc. of operator's configuration.The control strategy formulated for business is handed down to strategy and charge execution function (PolicyandChargingEnforcementFunction by PCRF, referred to as PCEF) or bearing binding and event reporting function (BearingBindingandEventReportFunction, referred to as BBERF) perform.Simultaneously PCRF can subscribe to bearing bed dependent event to PCEF and/or BBERF, timely perception when there is described event with convenient bearing bed, and changes control strategy.In addition, PCEF and business measuring ability (TrafficDetectionFunction, referred to as TDF) the PCC rule (PCEF) that can issue according to PCRF or application and detection control (ApplicationDetectionandControl is called for short ADC) rule (TDF) perform and apply detection and control function.
Proxy-Call Session Control Function (Proxy-CallSessionControlFunction, referred to as P-CSCF) can be a kind of AF.P-CSCF can provide the business information of IP Multimedia System (IPMultimediaSubsystem, referred to as IMS) to PCRF, to carry out Operational Visit to user by IMS carrying out QoS guarantee.In addition, P-CSCF also can obtain the relevant information of network of current UE access from PCRF, for the management of IMS, charging and control.At present, IMS can obtain the current positional information of user by PCC framework, for Lawful Interception, charging and Service control.Fig. 2 is the flow chart obtaining Access Network information according to P-CSCF in correlation technique (AF), and as shown in Figure 2, this flow process comprises the steps:
Step S202, subscriber equipment (UserEquipment, referred to as UE) is attached to network, initiate attachment flow, or UE initiates other PDN connection building process.IP-CAN session establishment, PCEF and PCRF sets up Gx session;
Step S204, P-CSCF (AF) receives Trigger message, and needing initially to provide business information to PCRF and ask Access Network information reporting (positional information that namely UE is current and/or time-zone information) (i.e. AF session establishment) or AF to receive triggering needs upgrade business information and ask Access Network to report (i.e. AF session modification);
Step S206, AF provide business information to PCRF or upgrade business information, ask Access Network information reporting (customer position information and/or time-zone information) simultaneously.Particularly, AF sends authentication authorization request (Authentication-AuthorizationRequest to PCRF, referred to as AAR) message, request Access Network information reporting is carried (AttributeValuePair, referred to as AVP) by Access Network information (Required-Access-Info) property value of asking.AF does not likely provide any business information yet, only asks Access Network information reporting;
Step S208, PCRF preserve relevant information.If AF initially provides business information (i.e. AF session establishment) to PCRF, then PCRF is according to AAR message carry information (the IP address of UE, user ID, public data network (PublicDataNetwork, referred to as PDN) mark etc.) conversate binding, by IP connected reference network (IPConnectivityAccessNetwork, referred to as the IP-CAN) session association that AF session and step S202 are set up;
Step S210, PCRF are to AF return authentication authorization response (AuthenticationAuthorizationAnswer, referred to as AAA) message;
Step S212, if AF provides business information, then PCRF is according to formulation PCC rules such as business information, user contract, and Access Network information reporting request (customer position information and/or time-zone information) comprises in PCC rule by PCRF, is supplied to PCEF.If AF does not provide business information, then PCRF this locality generates a PCC rule (wherein quality of service class mark (QoSClassIdentifer, referred to as QCI), distribute and keep priority (AllocationRetentionPriority, referred to as ARP) consistent with QCI, ARP of default bearing), and report request to be included in PCC rule Access Network information (customer position information and/or time-zone information), be supplied to PCEF;
Step S214, PCRF send diameter (Diameter) re-authorization request (Re-AuthenticationRequest, referred to as RAR) message to PCEF, carry PCC rule;
After step S216, PCEF verify PCC rule, PCEF returns acknowledge message to PCRF;
Step S218, PCEF install and perform PCC rule, initiate carrying and set up or bearing modification flow process;
Step S220, if after PCEF receives the Access Network information that Access Network reports, PCEF sends Diameter credit control request (CreditControlRequest, referred to as CCR) to PCRF, carries Access Network information (customer position information and/or time-zone information); If PCEF requests customer position information, and PCEF does not receive, then PCEF provides public land mobile network (PublicLandMobileNetwork, referred to as PLMN) to identify (ID) to PCRF;
Step S222, PCRF return acknowledge message Diameter Credit Control Answer (CreditControlAnswer, referred to as CCA) to PCEF;
Step S224, PCRF send DiameterRAR message to AF, carry the Access Network information (customer position information and/or time-zone information) that PCEF reports, if PCEF reports to PCRF is PLMNID, then PCRF also provides PLMNID to AF;
Step S226, AF return acknowledge message Diameter re-authorization response (Re-AuthenticationAnswer, referred to as RAA) to PCRF.
In above-mentioned flow process, PCRF supposes that the Access Network information reported in step S210 is that AF asks in step S206, and therefore PCRF adopts the AF session of step S206 to AF reporting position information.Here suppose that PCRF needs to keep the state information between step S206 and step S214.But if UE has initiated multiple IMS session in the short time, and this multiple IMS session triggers P-CSCF have sent the request of multiple Access Network information reporting to PCRF, thus PCRF have sent the request of multiple Access Network information reporting at short notice to PCEF.Fig. 3 is the schematic diagram of the stream migration scene according to correlation technique, and when PCRF receives the Access Network information reporting from PCEF, it is which Access Network information reporting request of corresponding A F that PCRF cannot judge that this reports.Particularly in the scene of stream migration (IPflowmobility) as shown in Figure 3.Different Business Streams may transmit in different Access Networks, and therefore the positional information of user may be different, and PCRF, when receiving multiple Access Network information continuously, may cause information reporting inaccurate.
The inaccurate problem of information reporting can be caused for PCRF in correlation technique when receiving multiple Access Network information reporting, not yet proposing effective solution at present.
