Description
Technical field
The present invention relates to the communications field, particularly, relate to third generation partner program (3rd GenerationPartnership Project abbreviates 3GPP as) grouping system, especially, relate to a kind of strategy and billing control method and system based on time zone, the current place of user.
Background technology
In third generation partner program stage 7 (3GPP Release7) standards system, strategy and billing function are realized by the strategy and control (Policy and Charging Control the abbreviates PCC as) framework that charges.The PCC framework is a functional framework that can be applied to multiple access technology, for example, it can be applied to universal mobile telecommunications system (Universal Mobile Telecommunications System, abbreviate UMTS as) terrestrial radio Access Network (UMTS Terrestrial Radio Access Network, abbreviate UTRAN as), global system for mobile communications (Global system for MobileCommunication abbreviates GSM as)/GSM data strengthens evolution (EDGE) wireless access network and intercommunicated wireless local area network (I-WLAN) etc.
PCC has mainly realized two big functions, that is, and and policy control functions and billing function.Fig. 1 is the general frame figure of PCC, below each logical functional entity and interface function thereof in the PCC framework shown in Figure 1 is described.
Application Function (Application Function abbreviates AF as) provides the access point of service application, and the employed Internet resources of these service application need carry out dynamic policy control.When service surface was carried out parameter negotiation, AF passed to policy control and charging regulation function entity (Policy and Charging Rules Function abbreviates PCRF as) with related service information.If these business information are tactful consistent with PCRF's, then PCRF accepts this negotiation; Otherwise PCRF refuses this negotiation, and provides the acceptable service parameter of PCRF in feedback simultaneously.Subsequently, AF can return to these parameters subscriber equipment (User Equipment abbreviates UE as).Wherein, the interface between AF and the PCRF is a Rx interface.
Policy control and charging regulation function entity (PCRF) are the cores of PCC, are 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 detection, gate (Gating Control), service quality (Qualityof Service the abbreviates QoS as) control of business data flow and based on the charging regulation of data flow etc.PCRF sends to the PCEF execution with the strategy and the charging regulation of its formulation, and simultaneously, PCRF needs also to guarantee that these rules are consistent with user's CAMEL-Subscription-Information.PCRF generates strategy and comprises with the foundation of charging regulation: obtain and professional relevant information from AF; Obtain and subscriber policy and billing control and subscription information from user-subscribed database (Subscription Profile Repository abbreviates SPR as); Obtain and carry the information of network of relation from PCEF.
PCEF (Policy and Control Enforcement Function): strategy and charging execution function entity, be usually located in the gateway (Gate-Way abbreviates GW as), carry out strategy and the charging regulation that PCRF formulated at loading end.PCEF detects business data flow according to the business datum flow filter in the rule that PCRF sent, and then these business data flows are carried out strategy and the charging regulation that PCRF formulated.When carrying was set up, the rule that PCEF sends according to PCRF was carried out the QoS mandate, and carried out gate control according to the execution of AF.According to the charging regulation that PCRF sends, PCEF carries out corresponding business data flow billing operation, and chargeing both can be online charging, also can be offline charging.If online charging, then PCEF needs and Online Charging System (Online Charging System abbreviates OCS as) carry out credit management together.During offline charging, exchange correlation charge information between PCEF and the off-line accounting system (OfflineCharging System abbreviates OFCS as).Interface between PCEF and the PCRF is the Gx interface, and the interface between the OCS is the Gy interface, and the interface between the OFCS is the Gz interface.PCEF generally is positioned on the gateway of network, as the packet data gateway among GGSN among the GPRS (GGSN) and the I-WLAN (Packet Data Gateway abbreviates PDG as).
User-subscribed database (SPR) has been stored and policy control and relevant subscriber policy and the billing control and subscription information of chargeing.Interface between SPR and the PCRF is the Sp interface.
Online Charging System (OCS) and PCEF carry out the control and the management of user credit under the online charging mode together.
Off-line accounting system (OFCS) is finished billing operation under the offline charging mode with PCEF.
In the prior art, PCRF the PCC rule that issues comprise PCEF when installed PCC rule, when delete/indication of time of deexcitation PCC rule, and when can be included in again the time indication etc. of the PCC rule that please look for novelty to PCRF.Utilize this mechanism, PCC can support based on the different time sections in a day user to be chargeed.
For example, at dead of night or morning, the indication in the PCC rule that PCEF issues according to PCRF, installed has the PCC rule than cheap rate, and the user is carried out strategy and the control of chargeing.In the time of by day, these PCC rules of PCEF deletion/deexcitation, and installed has the PCC rule of higher rate.Because UE constantly moves, when UE roamed into different time zone, PCRF just can not lay down a regulation according to the time zone at himself place.For example, when the time zone at user time zone, current place and PCRF self place was same time zone, PCC had formulated a PCC rule downloading and has given PCEF, and indication PCEF installs this rule at locality 8:00 in the morning, and 22:00 deletes this rule at night.When UE has taken place to move, with PCRF not when the same time zone, this rule must be the 8:00 point installation rule of the local time at UE place, the 22:00 deletion rule.Rather than the time in time zone, PCRF place.In the prior art, PCRF can't be known the be moved new time zone at place, back of UE, also just can't carry out strategy and charging is controlled based on time zone, the current place of UE.
Fig. 2 is the PCC framework of Release 8, PCRF passes through the Gxx interface to bearing binding and event reporting function entity (Bearer Binding and Event Reporting Function, abbreviate BBERF as) issue the relevant QoS rule of IP connection Access Network (IP-CAN) session, issue the relevant PCC rule of IP-CAN session by the Gx interface to PCEF.The BBERF function comprises the checking and the event report of bearing binding, up bearing binding, usually be present in the gateway, as EPS (Evolved PacketSystem, the grouping system of evolution) Serving Gateway (gateway), the ePDG in (EvolvedPacket Data Gateway, the packet data gateway of evolution) and be used to non-3 GPP access network pass of inserting the EPS system etc.Under the framework of Rel-8, PCRF can not accurately be known time zone, the current place of UE equally, can't carry out strategy and the control of chargeing according to time zone, the current place of UE.
