Strategy and charging control (PCC, Policy and Charging Control) be the part of EPS, each functional entity of PCC can distribute as follows in the EPS framework: the "Policy and Charging Rules Function entity, strategy and charging execution function entity (PCEF, Policy and Charging Enforcement Function) is present among the P-GW, bearing binding and event reporting function entity (BBERF, Bearer Binding andEvent Report Function) can be present among the S-GW, professional Application Function (AF, Application Function) is present in carrier network agreement (IP, Internet Protocol) business network, user-subscribed database (SPR, Subscription Profile Repository) can be unified with HSS.
In 3GPP, can find corresponding PDN network by APN (APN, Access Point Name).Usually UE is called an IP to a connection of PDN network and connects Access Network (IP-CAN, IP Connectivity Access Network) session.
PCC is applicable to the IP-CAN session of all 3GPP, its framework as shown in Figure 2, PCRF mainly is responsible for the formulation of strategy and charging regulation, by the Gx interface PCC strategy and the charging regulation of formulating is handed down to PCEF, PCEF installs and carries out the PCC strategy, and report dependent event, with the mutual charge information of charge system.
PCRF by the Gxx interface with service quality (QoS, the Quality of Service) rule downloading of business to BBERF, the mutual charge information of BBERF discord charge system, only responsible bearing binding and dependent event reports.AF provides business information by Rx interface to PCRF, and SPR has preserved the business information that the user contracts, and PCRF can be by the Sp interface to the signatory business information of SPR inquiring user.PCEF sends to Online Charging System (OCS by the Gy interface with online charging information, OnlineCharging System) carries out the statistics of online charging, by the Gz interface offline charging information is sent to off-line accounting system (OFCS, Offline Charging System).
At present, in the PCC framework, the business information that the user contracts among the beared information that the business information that PCRF provides according to AF, PCEF report and the SPR is formulated the PCC strategy, dynamically issues the PCC strategy to PCEF, comprises QoS and charge information in the policy information.
PCC also has the consumption monitoring function, the consumption in consumption that can the Real Time Monitoring user resources and the control billing mechanism.PCRF arranges and sending threshold value (such as duration and/or flow) is realized the consumption monitoring to PCEF, to formulate dynamic PCC strategy.When reaching threshold value or IP-CAN session termination, PCEF reports consumption (such as duration and/or the flow that consumes) to PCRF.PCRF stores the consumption information reporting when last IP-CAN session termination of user to SPR.
But, because PCRF is based on user class to the mechanism that reports of SPR, when certain IP-CAN session termination, if still there is other IP-CAN session in UE and in the IP-CAN conversation procedure, UE initiates again new IP-CAN session, at this moment, the duration that the UE that obtains from SPR is signatory and/or the surplus of flow do not conform to the real surplus amount, so that impact is to the threshold value accuracy of new IP-CAN session consumption monitoring.For example, when PCRF is selected in the new IP-CAN session of initiating, do not have (for example to select the PCRF identical with existing IP-CAN session, the situation of many PCRF load balancing), to cause the user's that selected PCRF gets access to from SPR business information accurate not, thereby affect the PCC strategy that PCRF formulates.
Therefore, when how to be implemented in the IP-CAN conversation establishing, the surplus from SPR gets access to accurate duration and/or flow has become present problem demanding prompt solution.
