Concrete, user data described in the present embodiment refers to user contracting data and user service data, can be such as user service identification, the user service data such as QoS control information, user traffic flow descriptor (business source IP address and port numbers, object IP address and port numbers, service protocol) needed for customer service that AF provides, and the user that SPR provides allow to use which business, does not allow to use which business, grade of service when using certain business, allow the user contracting datas such as the service bandwidth that uses and business rate.
PCRF can make the control strategy relevant to the business information in GPRS core net in conjunction with above-mentioned user data and the business information obtained by step 201.
In the present embodiment, because PCRF not only can obtain user data, the business information in GPRS core net can also be obtained by the mode such as mirror image, shunting, therefore PCRF can generate the control strategy relevant to network actual conditions according to the business information in GPRS core net, and the control strategy that PCRF is generated has more specific aim, more accurate.
Further, described strategy and charging rule functions module can gather core network service data by Diameter data protocol interface from Iu-PS, Gn, Gi interface described core net, and described strategy and charging rule functions module then can generate control strategy according to described core network service data and user data.
Concrete, described PCRF can adopt the mode such as mirror image, shunting from each interface of GPRS core net as Iu-PS, Gn, Gi intercept and capture signaling message and packet by Diameter data protocol interface.Wherein, Gi interface is the interface between GPRS and external packet data net, if the interface Gi in the gprs networks between GGSN and PDN is internet, be also simultaneously that IP address of terminal presents a little at outer data network, GPRS realizes interconnected by Gi interface and various public's Packet Based Network such as ISDN net; Gn interface be interface in same PLMN between SGSN and SGSN and between SGSN and GGSN as gsn, this interface protocol supports user data and the transmission about signaling; Iu-ps refers to the Iu interface of packet domain, is responsible for the Signalling exchange between core net and RNC, is used for transmitting the signaling between RNC and NODE-B and the data from wave point.The service traffics descriptor etc. that positional information residing when the signaling message intercepted and captured from above-mentioned each interface of GPRS core net in the present embodiment and packet specifically can include but not limited to the activation data of PDP, RAB assigns data, attachment message initial time, user use certain business, user use.PCRF can make the control strategy relevant to the business datum in GPRS core net in conjunction with above-mentioned core network service data and user data.
Preferably, in an embodiment as illustrated in figure 2, data analysis module gathers core network service data from Iu-PS, Gn, Gi interface described core net, and sends described core network service data by Diameter data protocol interface to PCRF.It is similar that data analysis module described in the present embodiment gathers from Iu-PS, Gn, Gi interface described core net the process that the specific implementation process of core network service data and above-mentioned PCRF gather core network service data from Iu-PS, Gn, Gi interface described core net, repeats no more herein.
In the present embodiment, because PCRF does not directly gather core network service data from core net, and only need the core network service data that reception data analysis module is sent by Diameter data protocol interface, thus simplified the work that PCRF gathers core network service data from core net, improve the safety and reliability of PCRF to a certain extent.
Further, the control strategy of generation is sent to strategy and charge execution function module by described strategy and charging rule functions module, carries out charging process by described strategy and charge execution function module according to described control strategy.

Fig. 3 is the flow chart of policy control method embodiment two of the present invention, and as shown in Figure 3, described policy control method can comprise the steps:
S301, data analysis module gathers core network service data from Iu-PS, Gn, Gi interface described core net;
In the present embodiment, described core network service data refer to the signaling message and packet that transmit in GPRS core net, the service traffics descriptor (comprising business time started, service ending time, service traffics) etc. that positional information residing when it specifically can include but not limited to, and the activation data of PDP, RAB assign data, attachment message initial time, user use certain business, user use.Data analysis module can adopt the mode such as mirror image, shunting from GPRS core net each network element interface as Iu-PS, Gn, Gi intercept and capture above-mentioned signaling message and packet.
S302, described data analysis module adopts DPI technology to the process of described core network service data analysis, generates core network service event;
Data analysis module carries out Data Analysis Services by technology such as deep packet inspection technicals (Deep Packet Inspection is called for short DPI) to the core network service data gathered, thus generates core network service event.Concrete, can according to the demand of operator pre-defined trigger event in data analysis module, write the threshold value thresholding of each trigger event simultaneously, and the algorithm corresponding with trigger event, the core network service data of collection are then generated core network service event according to the threshold value thresholding of predefined trigger event, trigger event and the algorithm corresponding with trigger event by data analysis module.
Such as, data analysis module to the core network service data gathered as positional information residing when user uses certain business, user the customer service running state data such as the service traffics descriptor that uses carry out simple statistical analysis, and the user network business event generated for this user according to the threshold value thresholding of predefined trigger event, trigger event and algorithm corresponding to trigger event.Concrete, can according to the trigger event of the demand of operator pre-defined customer service running status in data analysis module, as the trigger event defining customer service running status is: user A uses the trigger event of ftp business flow for mono-day, and for its allocation threshold thresholding be 50M, the algorithm that then this trigger event is corresponding adds up for the ftp flow amount used from 00:00 point to 24:00 user A, and accumulated value and threshold value 50M are compared, if the accumulated value X of the ftp flow amount that user A uses from 00:00 point to 24:00 is greater than 50M, the user network business event that then data analysis module generates is: user A used the flow of ftp business to exceed threshold value thresholding (X-50) M the same day.
Again such as, data analysis module to the core network service data gathered as the activation data of PDP, RAB assign the network operation status datas such as data and carry out simple statistical analysis, and according to the threshold value thresholding of predefined trigger event, trigger event and algorithm corresponding to trigger event generating network quality of service event.Concrete, can according to the trigger event of the demand of operator pre-defined network operation state in data analysis module, trigger event as define grid running status is: the trigger event of PDP activation success rate in network, and for its allocation threshold thresholding be 20%, then the PDP activation data that data analysis module obtains within a period of time are calculated, the algorithm that this trigger event is corresponding is: can pass through PDP activation number of success/PDP activation number of attempt * 100% as PDP activation success rate and try to achieve, and the PDP activation success rate Y and threshold value thresholding 20% that calculate gained are compared, if the PDP activation success rate Y of current calculating gained is less than threshold value thresholding 20%, the network servicequality event that then data analysis module generates is: current network is busy.
S303, described data analysis module sends described core network service event by Diameter data protocol interface to strategy and charging rule functions module;
Described data analysis module sends described core network service event by Diameter data protocol interface to PCRF, particularly, described core network service event can be for the user network business event of user or for whole network of network quality of service event.Or be described with above-described embodiment, in the present embodiment, data analysis module is sent in the user network business event of " user A used the flow of ftp business to exceed threshold value thresholding (X-50) M the same day " and the network servicequality event of " current network is busy " that generate in above-mentioned steps to PCRF by Diameter data protocol interface.
S304, described strategy and charging rule functions module generate control strategy according to described core network service event and described user data;
Concrete, user data described in the present embodiment refers to user contracting data and user service data, can be such as user service identification, the user service data such as QoS control information, user traffic flow descriptor (business source IP address and port numbers, object IP address and port numbers, service protocol) needed for customer service that AF provides, and the user that SPR provides allow to use which business, does not allow to use which business, grade of service when using certain business, allow the user contracting datas such as the service bandwidth that uses and business rate.
The core network service event that PCRF can send in conjunction with above-mentioned user data and data analysis module, as user network business event or network servicequality event, thus generates corresponding control strategy.Or be described with above-described embodiment, such as, PCRF formulates related control strategies, as user service identification, Business Stream descriptor, final QoS of survice, user gradation, user A used the flow of ftp business to exceed the business rate etc. of threshold value thresholding (X-50) M, excess flow the same day according to the user network business event received " user A used the flow of ftp business to exceed threshold value thresholding (X-50) M the same day " and user data.Again such as, PCRF formulates related control strategies according to the network servicequality event " current network is busy " received and user data, as user service identification, Business Stream descriptor, final QoS of survice, user gradation, current network is busy, current network quality is corresponding business rate etc.
S305, the control strategy of generation is sent to strategy and charge execution function module by described strategy and charging rule functions module, carries out charging process by strategy and charge execution function module according to described control strategy.
Further illustrate above steps below by way of a specific embodiment, in the present embodiment, PCRF can also be set in advance in the trigger event in data analysis module according to operator and generate control strategy.Such as, for existing PCC system, PCRF issues the trigger event of " customer location change " when issuing control strategy first, so subscriber equipment (UserEquipment when user moves to new position, be called for short UE) GPRS serving GPRS support node (Serving GPRS SUPPORTNODE can be informed, be called for short SGSN) customer location change event, the information of user position is informed SGSN in the lump simultaneously.But, generally for the signaling traffic load alleviating gn interface, and only when user reaches the standard grade for the first time, the cell information residing for user just can be informed PCRF by PCEF by SGSN, makes PCRF correctly can issue control strategy corresponding to this community, user place; And when the switching across community only occurs user in business use procedure, and SGSN is not when changing, new cell number only can be informed SGSN by UE, and SGSN can not inform PCEF by Gn mouth, now, PCRF just cannot know the cell information at the current place of user immediately, issues accurately for the control strategy of new community; Only have when the switching of SGSN-spanning occurs user, new cell number, new SGSN numbering just can be informed PCEF by SGSN, and PCEF just can report trigger event to PCRF: SGSN changes, thus triggering PCRF issues the new control strategy for reposition.
As shown in Figure 4, in embodiments of the present invention, data analysis module can adopt the mode such as mirror image, shunting each network element interface such as Iu-PS, Gn, Gi from GPRS core net to intercept and capture signaling message and packet, wherein, Gi interface is the interface between GPRS and external packet data net, if the interface Gi in the gprs networks between GGSN and PDN is internet, also be simultaneously that IP address of terminal presents a little at outer data network, GPRS realizes interconnected by Gi interface and various public's Packet Based Network such as ISDN net; Gn interface be interface in same PLMN between SGSN and SGSN and between SGSN and GGSN as gsn, this interface protocol supports user data and the transmission about signaling; Iu-ps refers to the Iu interface of packet domain, is responsible for the Signalling exchange between core net and RNC, is used for transmitting the signaling between RNC and NODE-B and the data from wave point.The service traffics descriptor etc. that positional information residing when the signaling message intercepted and captured from above-mentioned each interface of GPRS core net in the present embodiment and packet specifically can include but not limited to that PDP activation data, RAB assign data, attachment message initial time, user use certain business, user use.Concrete, when user A brings into use certain business, data analysis module can obtain SGSN information and the cell number information at user A place from SGSN by gn interface, and DPI process is carried out to the business information of the SGSN information at user A place obtained, cell number information and the current use of user, thus generate position event when user A brings into use certain business, and send this event by Diameter data protocol interface to PCRF; Simultaneously, data analysis module also continues by Iu-PS interface the positional information obtaining user A, and according to the requirement definition trigger event that operator presets, trigger event as definition is the trigger event of " change of user A subdistrict position ", therefore, when the switching across community occurs user A in business use procedure, data analysis module can also know the positional information at the current place of user A by Iu-PS interface, thus learns that the position of user changes information.Such as, user A can bring into use cell number information during certain business to store as threshold value thresholding by data analysis module, the algorithm that then this trigger event is corresponding is: the cell number information at the current place of user A obtained by Iu-PS interface and user A bring into use cell number information during this business to compare by data analysis module, if when the cell number information at the current place of user A and user A bring into use cell number information during this business inconsistent, the trigger event that then data analysis module generates is: user A subdistrict position changes, the cell number information at the current place of user A, data analysis module sends this trigger event by Diameter data protocol interface to PCRF, PCRF then generates the control strategy corresponding with this trigger event according to the trigger event of " user A subdistrict position changes, the cell number information at the current place of user A " that receive and the user data that obtained by AF with SPR, business rate etc. as corresponding in user service identification, Business Stream descriptor, final QoS of survice, user gradation, user current place cell number, user current place cell number, and this control strategy is sent to PCEF, carry out Business Processing by PCEF according to control strategy.
Alternatively, as the another kind of execution mode of above-described embodiment, user data can also be gathered by data analysis module from AF and SPR, thus make PCRF only need to receive trigger event and the user data of data analysis module transmission, and directly not carry out alternately with AF and SPR.
In the present embodiment, GPRS core network service data are obtained owing to adopting data analysis module, and generate core network service event after analyzing and processing is carried out to it, by the core network service event transmission generated to be generated the information source of control strategy to PCRF as PCRF, therefore, PCRF is made to obtain more accurate information, thus the control strategy generated also has more specific aim, more realistic demand, such as solve the switching that user only occurs across community in business use procedure, and SGSN is not when changing, PCRF is because cannot knowing cell information accurately and cannot issuing the problem of the control strategy for community.
Again due to for most Internet service, when business is brought into use, do not have equipment can serve as the function of AF, inform the information such as the server address of this business of PCRF, that is PCRF cannot know Business Stream descriptor, therefore, just need in PCEF built-in business detection mechanism in existing PCC system, as passed through DPI monitoring stream through the packet of PCEF, obtaining the Business Stream descriptor of this business, then informing PCRF by Gx interface.And in embodiments of the present invention, be carry out DPI monitoring by data analysis module, therefore, PCEF need not support DPI function.
