Description
Technical field
The present invention relates to communication technical field, more specifically, relate to a kind of ground access roaming scene of visiting and support by the method and system of patronage data connection.
Background technology
Third generation partner program (3rd Generation Partnership Project; Abbreviate 3GPP as) strategy be a functional framework that can be applied to multiple access technology with control (Policy and Charging Control the abbreviates PCC as) framework that charges.For example; Be applied to UMTS (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 Mobile Communication; Abbreviate GSM as)/the GSM data strengthen the grouping system (Evolved PacketSystem abbreviates EPS as) of evolution (Enhanced Data rates for Global Evolution abbreviates EDGE as) wireless access network, intercommunicated wireless local area network (I-WLAN) and evolution etc.
Fig. 1 is the sketch map of the non-roaming framework of Rel-8 PCC of correlation technique, below with reference to Fig. 1 each logical functional entity and interface function thereof in this PCC framework 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 is carried out parameter negotiation; AF passes to strategy and charging regulation function entity (Policyand Charging Rules Function with related service information; Abbreviate PCRF as), if these business information and PCRF's is tactful consistent, then PCRF accepts and should consult; Otherwise the PCRF refusal should be consulted, and in feedback, provided the acceptable service parameter of PCRF simultaneously.Subsequently, AF can return to subscriber equipment (User Equipment abbreviates UE as) with these parameters.Wherein, the interface between AF and the PCRF is a 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 monitoring, gate (Gating Control), service quality (Quality of Service the abbreviates QoS as) control of business data flow and based on the charging regulation of data flow etc.PCRF sends to strategy and charging execution function entity (Policy and Charging Enforcement Function with the strategy and the charging regulation of its formulation; Abbreviate PCEF as) carry out; Simultaneously, PCRF need guarantee that also 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 user policy, 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 is used for carrying out strategy and the charging regulation that PCRF formulated at loading end.PCEF monitors 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 based on 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 (Offline Charging 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 is usually located in the gateway (Gate-Way abbreviates GW as) of network, like the packet data gateway among GGSN among the GPRS (GGSN) and the I-WLAN (Packet Data Gateway abbreviates PDG as).
Bearing binding and event reporting function entity (Bearer Binding and Event ReportingFunction abbreviates BBERF as), its function comprises the checking and the event report of bearing binding, up bearing binding.When UE inserts through E-UTRAN; And when adopting the PMIPv6 agreement between S-GW and the P-GW; BBERF is located in S-GW, and when UE inserted through the non-3GPP connecting system of trusted, BBERF was positioned at the trusted non-3 GPP access network and closes; When UE inserts through trustless non-3GPP connecting system, BBERF is positioned at the packet data gateway (Evolved Packet DataGateway abbreviates ePDG as) of evolution.At this moment, PCEF no longer carries out the bearing binding function.
User-subscribed database (SPR) has been stored and the policy control and the relevant user policy, billing control and subscription information that charges.Interface between SPR and the PCRF is the Sp interface.
Online Charging System (OCS) carries out the control and the management of user credit under the online charging mode with PCEF.
Off-line accounting system (OFCS) is accomplished the billing operation under the offline charging mode with PCEF.
Above PCC framework has been realized UE is packet data network (Packet Data Network of visit through each functional entity; Abbreviate PDN as) policy and charging control of IP connection access network (IP ConnectivityAccess Network the abbreviates IP-CAN as) session of being set up.
At present, the support of PCC framework is called by the patronage data and connects (Sponsored data connectivity).What is called is connected the consumption consumption that is meant that user institute access service produces by the patronage data, is not to be born by user oneself, but is born by professional provider.At this moment; When the user initiates such Operational Visit; AF is when providing the business information that is connected by the patronage data to PCRF; Also provide by patronage data link information, like sponsor sign (Sponsor Identity), identification service provider (Application ServiceProvider) and application message, and such professional consumption threshold value of professional provider's sponsored visit that possibly provide to PCRF (be user can such professional consumption of free access).
For the policy and charging control that realizes connecting, in SPR, will preserve by patronage data connection document, comprising the application information list of sponsor's sign and each Applications Service Provider to by the patronage data.For being connected by the patronage data, PCRF also will connect document based on the quilt patronage data of from SPR, obtaining and authorize the data link information of being supported that AF provides except that business information being carried out the QoS mandate, whether allow to carry out being supported the data connection.
Yet; Prior art does not solve following problem: insert under the scene (as shown in Figure 2 when UE is in visit ground; HPLMN is meant the ownership place public land mobile communication network among Fig. 2), the UE visit is positioned at professional by the connection of patronage data that visited network provides, and this moment is because home network maybe be owing to there not being corresponding subscription data; And it is professional to cause ownership place PCRF refusal to authorize this quilt to support data to connect, and is supported data to connect business thereby make UE when roaming, can't visit this.
