For the purpose, technical scheme and the advantage that make the embodiment of the invention clearer, below in conjunction with the accompanying drawing in the embodiment of the invention, technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that obtains under the creative work prerequisite.
Fig. 2 is the flow chart of policy control method embodiment one of the present invention, and as shown in Figure 2, the policy control method of the present embodiment can comprise:
Step S201, strategy and charging rule functions module are obtained the business information in the core net;
In the present embodiment, the business information in the described core net can be the core net business datum, such as signaling message and the packet that transmits in the core net; Perhaps described business information also can be that the signaling message that transmits in the described core net and packet are carried out core net business event after the analyzing and processing.For example, the core net business datum can be from general packet radio service (General Packet Radio Service, be called for short GPRS) middle signaling message and the packet that transmits, PCRF passes through the modes such as mirror image, shunting from each interface of GPRS core net such as Iu-PS, Gn, Gi intercepting and capturing signaling message and packet.Wherein, the Gi interface is the interface between GPRS and the external packet data net, such as GGSN in GPRS network and public data network (Public Data Network, abbreviation PDN) the interface Gi between is internet, it simultaneously also is IP address of terminal presenting a little of data network externally, GPRS passes through Gi interface and various public's Packet Based Network such as integrated services digital network (Integrated Services Digital Network is called for short ISDN) and realizes interconnected; Gn interface is between the middle SGSN of same public land mobile network (Public Land Mobile Network is called for short PLMN) and SGSN and interface such as gsn between SGSN and GGSN, and this interface protocol is supported the transmission of user data and relevant signaling; Iu-ps refers to the Iu interface of packet domain, be responsible for core net and radio network controller (Radio Network Controller, be called for short RNC) between Signalling exchange, be used for transmitting between RNC and base station (NODE-B) signaling and from the data of wave point.Signaling message and the packet intercepted and captured from above-mentioned each interface of GPRS core net in the present embodiment specifically can include but not limited to packet data protocol (Packet Data Protocol, be called for short PDP) activation data, user plane carrying (Radio Access Bearer is called for short RAB) assignment data, adhere to the message zero-time, residing positional information, the employed service traffics descriptor of user etc. when the user uses certain professional.The signaling message that transmits in to above-mentioned core net and packet carry out generating core network service event after the analyzing and processing.Concrete, can be according to demand pre-defined trigger event in data analysis module of operator, write simultaneously the threshold value thresholding of each trigger event, and the algorithm corresponding with trigger event, data analysis module then generates core network service event according to threshold value thresholding and the algorithm corresponding with trigger event of predefined trigger event, trigger event.
Step S202, described strategy and charging rule functions module generate control strategy according to described business information and user data.
Concrete, user data described in the present embodiment refers to user contracting data and user service data, such as can being the user service datas such as the required QoS control information of the AF user service identification, the customer service that provide, user traffic flow descriptor (professional source IP address and port numbers, purpose IP address and port numbers, service protocol), and the user that SPR provides allows to use which business, does not allow to use which business, the grade of service when using certain professional, allow the user contracting datas such as the service bandwidth that uses and professional rate.
PCRF can make the control strategy relevant with business information in the GPRS core net in conjunction with above-mentioned user data and by the business information that step 201 is obtained.
In the present embodiment, because PCRF not only can obtain user data, can also obtain business information in the GPRS core net by modes such as mirror image, shuntings, therefore PCRF can generate the control strategy relevant with the network actual conditions according to the business information in the GPRS core net, so that the control strategy that PCRF generates has more specific aim, more accurate.
Further, described strategy and charging rule functions module can gather the core net business datum by Iu-PS, Gn, the Gi interface of Diameter data protocol interface from described core net, and described strategy and charging rule functions module then can generate control strategy according to described core net business datum and user data.
Concrete, described PCRF can adopt by Diameter data protocol interface the modes such as mirror image, shunting from each interface of GPRS core net such as Iu-PS, Gn, Gi intercepting and capturing signaling message and packet.Wherein, the Gi interface is the interface between GPRS and the external packet data net, being internet such as the interface Gi between GGSN in GPRS network and the PDN, also is simultaneously IP address of terminal presenting a little of data network externally, and GPRS realizes interconnected by Gi interface and various public's Packet Based Network such as ISDN net; Gn interface is among the same PLMN between SGSN and SGSN and interface such as gsn between SGSN and GGSN, and this interface protocol is supported the transmission of user data and relevant signaling; Iu-ps refers to the Iu interface of packet domain, is responsible for the Signalling exchange between core net and the RNC, be used for transmitting between RNC and the NODE-B signaling and from the data of wave point.Activation data, the RAB assignment data that the signaling message of intercepting and capturing from above-mentioned each interface of GPRS core net in the present embodiment and packet specifically can include but not limited to PDP, adhere to the message zero-time, residing positional information, the employed service traffics descriptor of user etc. when the user uses certain professional.PCRF can be in conjunction with above-mentioned core net business datum and user data and is made the control strategy relevant with business datum in the GPRS core net.
Preferably, in embodiment as shown in Figure 2, Iu-PS, Gn, the Gi interface of data analysis module from described core net gathers the core net business datum, and sends described core net business datum by Diameter data protocol interface to PCRF.The process of Iu-PS, Gn from described core net of the specific implementation process that Iu-PS, the Gn of data analysis module described in the present embodiment from described core net, Gi interface gather the core net business datum and above-mentioned PCRF, Gi interface collection core net business datum is similar, repeats no more herein.
In the present embodiment, because PCRF does not directly gather the core net business datum from core net, and the core net business datum that only needs the receive data analysis module to send by Diameter data protocol interface, thereby simplified PCRF gathers the core net business datum from core net work, improved to a certain extent the safety and reliability of PCRF.
Further, described strategy and charging rule functions module are sent to strategy and charge execution function module with the control strategy that generates, and carry out charging by described strategy and charge execution function module according to described control strategy and process.
The present embodiment has adopted Diameter data protocol interface to gather the core net business datum from each interface on the core net, because Diameter requires each the node response on the chain of agents or confirms each request, has retransmission mechanism, therefore, fail safe, the reliability of PCRF image data have been improved.In addition, because the information source of PCRF generation control strategy is more extensive, so the control strategy that PCRF formulates is also more targeted, thereby so that PCEF can carry out the charging processing more targetedly.
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 Iu-PS, Gn, the Gi interface from described core net gathers the core net business datum;
In the present embodiment, described core net business datum refers to the signaling message and the packet that transmit in the GPRS core net, its specifically can include but not limited to PDP activation data, RAB assignment data, adhere to the message zero-time, residing positional information, the employed service traffics descriptor of user (comprising professional time started, service ending time, service traffics) etc. when the user uses certain professional.Data analysis module can adopt the modes such as mirror image, shunting each network element interface such as Iu-PS, Gn, Gi from the GPRS core net to intercept and capture above-mentioned signaling message and packet.
S302, described data analysis module adopt the DPI technology that described core net business datum is carried out analyzing and processing, generate core network service event;
Data analysis module carries out data analysis by technology such as deep packet inspection technicals (Deep Packet Inspection is called for short DPI) to the core net business datum that gathers to be processed, thereby generates core network service event.Concrete, can be according to demand pre-defined trigger event in data analysis module of operator, write simultaneously the threshold value thresholding of each trigger event, and the algorithm corresponding with trigger event, data analysis module then generates core network service event with the core net business datum that gathers according to threshold value thresholding and the algorithm corresponding with trigger event of predefined trigger event, trigger event.
For example, the customer service running state data such as residing positional information, the employed service traffics descriptor of user were carried out simple statistical analysis when data analysis module used certain professional to the core net business datum that gathers such as user, and generated user network business event for this user according to the threshold value thresholding of predefined trigger event, trigger event and algorithm corresponding to trigger event.Concrete, can be according to the trigger event of demand pre-defined customer service running status in data analysis module of operator, as the trigger event that defines the customer service running status is: user A used the trigger event of ftp business flow in one day, and be that its allocation threshold thresholding is 50M, the algorithm that then this trigger event is corresponding is for employed ftp flow amount adds up from the 00:00 point to 24:00 to user A, and accumulated value and threshold value 50M compared, if the accumulated value X of user A from the 00:00 point to the employed ftp flow amount of 24:00 is greater than 50M, then the user network business event of data analysis module generation is: user A used the flow of ftp business to exceed threshold value thresholding (X-50) M the same day.
Again for example, data analysis module carries out simple statistical analysis to network operation status datas such as the activation data of the core net business datum that gathers such as PDP, RAB assignment data, and according to the threshold value thresholding of predefined trigger event, trigger event and algorithm corresponding to trigger event and generating network quality of service event.Concrete, can be according to the trigger event of demand pre-defined network operation state in data analysis module of operator, trigger event such as the define grid running status is: PDP activates the trigger event of success rate in the network, and be that its allocation threshold thresholding is 20%, the PDP activation data that then data analysis module was obtained within a period of time calculates, the algorithm that this trigger event is corresponding is: can activate number of success/PDP activation number of attempt * 100% by PDP such as PDP activation success rate and try to achieve, and the PDP that will calculate gained activates success rate Y and threshold value thresholding 20% compares, if the PDP of current calculating gained activates success rate Y less than threshold value thresholding 20%, then the network servicequality event of data analysis module generation is: current network is busy.
S303, described data analysis module sends described core net business event by Diameter data protocol interface to strategy and charging rule functions module;
Described data analysis module sends described core net business event by Diameter data protocol interface to PCRF, particularly, described core net business event can be for user's user network business event or for whole network of network quality of service event.Or describe with above-described embodiment, in the present embodiment, data analysis module is sent in the network servicequality event of user network business event He " current network is busy " of " user A used the flow of ftp business to exceed threshold value thresholding (X-50) M the same day " that generate in the 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 net business event and described user data;
Concrete, user data described in the present embodiment refers to user contracting data and user service data, such as can being the user service datas such as the required QoS control information of the AF user service identification, the customer service that provide, user traffic flow descriptor (professional source IP address and port numbers, purpose IP address and port numbers, service protocol), and the user that SPR provides allows to use which business, does not allow to use which business, the grade of service when using certain professional, allow the user contracting datas such as the service bandwidth that uses and professional rate.
PCRF can in conjunction with the core net business event of above-mentioned user data and data analysis module transmission, such as user network business event or network servicequality event, thereby generate corresponding control strategy.Or describe with above-described embodiment, for example, PCRF formulates the relevant control strategy according to the user network business event " user A used the flow of ftp business to exceed threshold value thresholding (X-50) M the same day " that receives and user data, uses the same day flow of ftp business to exceed the professional rate etc. of threshold value thresholding (X-50) M, excess flow such as user service identification, Business Stream descriptor, final QoS of survice, user gradation, user A.Again for example, PCRF formulates the relevant control strategy according to the network servicequality event " current network is busy " that receives and user data, such as user service identification, Business Stream descriptor, the final professional rate that QoS of survice, user gradation, current network are busy, the current network quality is corresponding etc.
S305, described strategy and charging rule functions module are sent to strategy and charge execution function module with the control strategy that generates, and carry out charging by strategy and charge execution function module according to described control strategy and process.
Below further specify above steps by a specific embodiment, in the present embodiment, PCRF can also be set in advance in the trigger event in the data analysis module and generate control strategy according to operator.For example, for existing PCC system, PCRF issues the trigger event of " customer location change " when issuing control strategy first, subscriber equipment (User Equipment when the user moves to new position so, be called for short UE) can inform GPRS serving GPRS support node (Serving GPRS SUPPORT NODE, be called for short SGSN) customer location change event, simultaneously the information of user position is informed SGSN in the lump.But, usually in order to alleviate the signaling traffic load of gn interface, and only when the user reaches the standard grade for the first time, just SGSN can inform PCRF by PCEF with the residing cell information of user, so that PCRF can correctly issue this control strategy corresponding to residential quarter, user place; And in professional use procedure, only stride the switching of residential quarter as the user, and SGSN is not when changing, UE only can inform SGSN with new cell number, and SGSN can not inform PCEF by the Gn mouth, at this moment, PCRF just can't be known the cell information at the current place of user immediately, issues accurately the control strategy for new residential quarter; Only have when the switching of SGSN-spanning occurs the user, SGSN just can inform PCEF with new cell number, new SGSN numbering, and PCEF just can report trigger event to PCRF: SGSN changes, thereby 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 modes such as mirror image, shunting each network element interface such as Iu-PS, Gn, Gi intercepting and capturing signaling message and packet from the GPRS core net, wherein, the Gi interface is the interface between GPRS and the external packet data net, be internet such as the interface Gi between GGSN in GPRS network and the PDN, simultaneously also be IP address of terminal presenting a little of data network externally, GPRS realizes interconnected by Gi interface and various public's Packet Based Network such as ISDN net; Gn interface is among the same PLMN between SGSN and SGSN and interface such as gsn between SGSN and GGSN, and this interface protocol is supported the transmission of user data and relevant signaling; Iu-ps refers to the Iu interface of packet domain, is responsible for the Signalling exchange between core net and the RNC, be used for transmitting between RNC and the NODE-B signaling and from the data of wave point.Signaling message and the packet of intercepting and capturing from above-mentioned each interface of GPRS core net in the present embodiment specifically can include but not limited to PDP activation data, RAB assignment data, adheres to the message zero-time, residing positional information, the employed service traffics descriptor of user etc. when the user uses certain professional.Concrete, when user A brings into use certain professional, data analysis module can obtain by gn interface SGSN information and the cell number information at user A place from SGSN, and the business information of SGSN information, cell number information and the current use of user at the user A place that obtains is carried out DPI process, thereby position event when generating user A and bringing into use certain professional, and send this event by Diameter data protocol interface to PCRF; Simultaneously, data analysis module also continues to obtain the positional information of user A by Iu-PS interface, and according to the predefined requirements definition trigger event of operator, trigger event such as definition is the trigger event of " change of user A subdistrict position ", therefore, when user A strode the switching of residential quarter in professional use procedure, data analysis module can also be known by Iu-PS interface the positional information at the current place of user A, thereby learnt that user's position changes information.For example, cell number information when data analysis module can bring into use user A certain professional is stored as the threshold value thresholding, the algorithm that then this trigger event is corresponding is: the cell number information the when cell number information at the current place of user A that data analysis module will obtain by Iu-PS interface and user A bring into use this business compares, when the cell number information when if the cell number information at the current place of user A and user A bring into use this business is inconsistent, then the trigger event of data analysis module generation 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 by the user data that AF and SPR obtain, such as professional rate corresponding to user service identification, Business Stream descriptor, the final current place of QoS of survice, user gradation, user cell number, the current place of user cell number etc.; And this control strategy sent to PCEF, carry out Business Processing by PCEF according to control strategy.
Alternatively, another kind of execution mode as above-described embodiment, can also gather user data from AF and SPR by data analysis module, thereby so that PCRF only needs trigger event and the user data of the transmission of receive data analysis module, and directly do not carry out alternately with AF and SPR.
In the present embodiment, owing to adopting data analysis module to obtain GPRS core net business datum, and it is carried out generating after the analyzing and processing core network service event, transfer to PCRF generates control strategy as PCRF information source by the core net business event that will generate, therefore, so that PCRF obtains more accurate information, thereby the control strategy that generates also has more specific aim, more realistic demand, for example solve the user and in professional use procedure, only striden the switching of residential quarter, and SGSN is not when changing, and PCRF can't issue the problem for the control strategy of residential quarter because knowing cell information accurately.
Again because for most Internet service, when business is brought into use, there is not equipment can serve as the function of AF, inform the information such as server address that PCRF should business, that is to say that PCRF can't know the Business Stream descriptor, therefore, just need to be in the built-in professional mechanism of surveying of PCEF in existing PCC system, as by the packet of DPI monitoring stream through PCEF, obtain this professional Business Stream descriptor, then inform PCRF by the Gx interface.And in embodiments of the present invention, be to carry out the DPI monitoring by data analysis module, therefore, PCEF needn't support the DPI function.
