Description

A kind of method and system of definite policing rule

Technical field

The present invention relates in network treatment technology, particularly a kind of method and system of definite policing rule to policing rule.

Background technology

In different networks, how to determine that also the distributing policy rule carries out for the execution entity, as policy control and charging regulation (PCC, Policy Control and Charging) or service quality (QoS, Quality of Service) strategy is or/and charging regulation becomes a problem demanding prompt solution.

Micro-wave access to global intercommunication (WiMAX, Worldwide Interoperability for MicrowaveAccess) network work group (NWG, Network Work Group) the up-to-date service quality (QoS of standard, Quality of Service) framework as shown in Figure 1, portable terminal (MS, Mobile Station) be user's portable terminal, the user is undertaken alternately by MS and network; Service flow management entity (SFM, Service Flow Manager) is used to set up user traffic flow and for the traffic flow assignment Radio Resource set up etc., this functional entity is present among the ASN; Service flow authorization entity (SFA, Service FlowAuthorization) is used to the mandate of Business Stream, and this functional entity is present among the ASN; Policy functional entity (PF, Policy Function, PF) be used to user service flow that strategy is provided, this functional entity is by Internet Service Provider (NSP, Network Service Provider) provides, when the user roams, will have visit PF (V-PF, Visited PF) and local PF (H-PF, Home PF); Application Function (AF, Application Function) provides the functional entity of application service, user's MS is directly by application layer protocol connected reference AF, AF will notify PF initiatively to create Business Stream for the user, this functional entity is provided by Internet Service Provider (NSP, Network Service Provider).

Internet protocol multimedia subsystem (IMS, IP Multiedia Subsystem), as the core of next generation network " fusion ", realized the Core Network Architecture of the functions such as foundation, maintenance and management of Internet protocol (IP, Internet Protocol) multimedia service.Can between heterogeneous network, realize intercommunication based on IMS.The functive of IMS framework mainly contains:

(P-CSCF, Proxy-CSCF), it is user's first contact point in the IMS system to proxy-call session control function.The network of same operator can have one or more P-CSCF.Its major function is: based on the home domain name (home network domain name) that UE in the request provides, transmit session initiation protocol registration (SIP REGISTER) request of UE and give inquiry CSCF (I-CSCF); After the user registration success, can transmit user's SIP request and response message and give serving CSCF (S-CSCF); Charge information is sent to Charging Collection Function (CCF, Charging Collection Function); Carry out the medium correction; Check whether medium type in the SIP session, coded format etc. meet the requirements, can the requirement of QOS be satisfied etc.; Mutual by Gq reference point and strategy decisive function (PDF, Policy DecisionFunction), the transmission policy configuration information is to realize media authorization; Other functions are compressed as sip message; Protection sip message integrality, keep and the user between Security Association etc.

PDF is responsible for generating strategy according to the session and the medium relevant information that obtain from P-CSCF, and it is as a policy decision point based on LAN services rule (SBLP, Service Based Local Policy) control.Its function is: store session and medium relevant information; Generate authorization token and be used to identify PDF and session; When the bearer authorization request of receiving from Internet protocol-IP-CAN, provide authorization decision according to the session and the medium relevant information of storage; When session change process has been revised session and medium relevant information, upgrade corresponding authorization decision; Enable the ability of the carrying of having authorized; Forbid the carrying of having authorized, but keep the ability of mandate; Transmit an IMS charging identifier and give ggsn (GGSN), and transmit a GPRS (GPRS) charging identifier and give P-CSCF.

The WiMAX standard has just been done preliminary description in the R1 stage for merging with IMS: in the WiMAX-IMS in R1 stage integration program, the WiMAX network is just as an IP transmission network between IMS client and the IMS network, and the original framework of WiMAX network, interface are as changing the fusion that just can support this kind mode.

The PCC framework is a problem that mainly solves in the version 7 (R7) of 3GPP, its objective is the integrated of Qos and charging, and 3GPP has set up special PCC subject under discussion group and studied this problem.The current framework of PCC is the scheme that fusion forms based on charge on traffic (FBC, Flow Based Charging) framework according to the SBLP framework of R5 definition among the 3GPP and R6 definition.As shown in Figure 2: wherein, PDF among the SBLP and the CRF among the FBC are fused into a policy control and charging regulation function entity (PCRF, Policy and Charging Rules Function), PDF and CRF are the functional entitys of Rulemaking.With PEP among the SBLP and the transmission surface function (TPF among the FBC, TrafficPlane Function) is fused into policy control and charging execution function entity (PCEF, Policy andCharging Enforce Function), be gateway (GW), PEP and TPF are the functional entitys of executing rule.In addition, original function before application function (AF, Application Function) is still inherited promptly provides business information.

In addition, Go and Gx interface are merged into Gx+, provide charging regulation and policy control rule to PEP/TPF respectively, Gx interface support policy controlled function, be referred to as policy control (FBP) based on stream, the interface Gq and the Rx of PCC session-oriented layer and application layer merge into Rx+, and Gq is very similar on function with Rx interface, and the information of relevant IMS session of session control layer and media parameter is passed to PCC.Having increased a storing predetermined strategy (SPR, Subscription Profile Repository) functional entity in PCC, mainly is the entity that is used for preserving the signatory strategy of real-time user, better keeps network and user's policy consistency in PCC.

PCRF has comprised PDF among the SBLP and the function of the CRF among the FBC, provides QoS authorization message and charging regulation to GW.The initial conditions of PCRF formulation charging regulation comprises the information of three aspects: session that AF provides and medium relevant information; And the network carrying relevant multiple information signatory that PCEF provides with the user; That disposed on the PCRF or SPR provides with signatory, professional relevant information etc.After receiving the business information of AF, PCRF may need to check whether allow AF to transmit these information to PCRF.PCRF is responsible for controlling the behavior after GW receives SDF, for example packet loss operation, and this can realize by issuing PCC rules.Meanwhile, PCRF also must guarantee in the mapping of user's surface current amount, the processing of GW consistent with user's signatory situation, and this can realize by obtaining relevant information to SPR.For GPRS, PCRF must be able to support the policy control based on PDP Context.

PDF provides and authorizes QoS to GW, and GW compares the QoS request of this QoS and UE subsequently, determines subsequent operation then.In PCC, GW offers PCRF with the QoS of request, and the QoS and the PCRF that are contrasted this request by PCRF go up existing mandate QoS, and finish follow-up operation.That is to say, move on on the partial function of original GW and go among the PCRF to have carried out.In PCC, PCRF is only controlled entity, and GW just carries out entity.

In the PCC system, GW has comprised the TPF function of PEP and the FBC of SBLP, provides the strategy execution of user's surface current amount and charging regulation to implement.In addition, PCEF also has a feedback function, also is that it need be to PCRF feedback user face event message.For a SDF who is under the policy control, when having only corresponding gate to be in the state of open, GW just can allow it pass through.For a SDF who is under the FBC control, when having only the charging regulation that has an activation, GW just can allow it pass through.In the heavy qualification process of credit, GW also may allow a SDF to pass through.

No matter be policy control, the control of still chargeing all is to realize by carrying out the PCC rule that PCRF issued.May only carry the policy control rule in the PCC rule, also may only comprise charging regulation, also may comprise policing rule and charging regulation simultaneously.This execution mode help SBLP FBC to the smooth evolution of PCC, also help PCC and possess applicability widely.

WiMAX network and IMS fusion architecture that WiMAX network R1.5 version is formulated meet the requirement of PCC framework.

Lifting earlier the WiMAX network is the example explanation, in the WiMAX network, be divided into ASN and and CSN, physical NE has BS, ASN-GW among the ASN, and aaa server and PCRF functive etc. are arranged among the CSN.An ASN-GW links to each other with a plurality of BS, and these BS are managed.From Qos, SFM can realize on BS, and SFA or PCEF can realize on ASN-GW.

In the WiMAX network, GW is divided into anchor GW and service GW notion again, makes an explanation below:

(ASN-GW originally is called service ASN-GW when a MS switches between two ASN-GW, new ASN-GW is called target ASN-GW), will there be two possible scenes in the transmission of user conversation from target ASN-GW to CSN, respectively shown in the scene one and scene two of Fig. 3.

Scene one: target ASN-GW is to setting up a R4 data channel between the anchor ASN-GW, user data arrives first anchor ASN-GW by target ASN-GW, then by anchor ASN-GW again to CSN.

Scene two: target ASN-GW grappling user conversation again is directly connected to CSN as new anchor ASN-GW.

These two kinds of scenes all can take place when ASN-GW switches, generally speaking, user conversation will be through target ASN-GW to anchor ASN-GW, again by anchor ASN-GW to CSN, but when original anchor ASN-GW can initiatively require serve as new anchor ASN-GW by it to target ASN-GW in some cases, or as target ASN-GW to think that anchor ASN-GW responded slow, under the situations such as inadequate resource, can initiatively initiate request, require to serve as the new ASN-GW that retouches to anchor ASN-GW.

In order to represent that clearly same user is through the situation of a plurality of GW in the ASN, below the ASN-GW that will provide the R3 data channel to link to each other with core net is called R3GW, the GW that directly links to each other with BS is called R6 GW, under a lot of scenes, R3 GW and R6 GW are same GW, be accompanied by user terminal and move, after various handoff scenario took place, R3GW may be two different GW with R6GW.

In wireless network, BS and Cell are two basic conceptions, introduce respectively below:

BS is the wireless base station; Cell is the sub-district (perhaps crying the sector) below the base station, possible configuration becomes a plurality of carrier frequency and a plurality of sub-districts (perhaps crying the sector) of forming in base station BS, just the overlay area of BS can be divided into a plurality of sub-districts (perhaps crying the sector), and certain base station also can have only a sub-district.When MS moves, can cause the switching between the same BS different districts Cell, that is to say that to have BS constant, but the switching that Cell changes.

The introducing of diameter (Diameter) agreement is as the aaa protocol of supporting based on the AAA framework of IP technology.The Diameter major function is: during the resource of authentication (Authentication) user in using network system to the affirmation of user identity; Authorize (Authorization) network system authorized user to use its resource in a particular manner; (Accounting) charges) network system is collected, recording user is to the use of Internet resources, so that collect resource accounting to the user, perhaps is used for purposes such as audit.With Internet access business supplier ISP is example, and user's network insertion operating position can be got off by accurate recording by flow or time.

Diameter message is made up of message header and message body, and the message body part is a unit with AVP, and each AVP has carried a concrete message parameter value, and each AVP comprises AVP head and Data part.Wherein, Event-Trigger AVP is an enumeration type, when this AVP when PCRF sends to PCEF, after being used to refer to which incident generation, PCEF need apply for the PCC rule again, when this AVP when PCEF sends to PCRF, corresponding some incident of its indication takes place.

Diameter message comprises credit control request (CCR) message and credit control response message (CCA), and wherein, CCR message is to be a service request credit authorization between client and the credit control server; CCA is used for confirming to receive CCR message between credit control server and the client.

Underdraw as can be seen from above-mentioned, the 3GPP normal structure at first proposes the PCC framework, because the PCC framework meets Qos control and the network development trend of chargeing based on Business Stream, so increasing standard formulation tissue is introduced the part of PCC standard as its standard, corresponding PCC framework is originally what 3GPP formulated, a lot of characteristics only meet the standard of 3GPP, so all can carrying out some to the PCC framework, these various normal structures of introducing the PCC framework improve, so that the situation of the network of its adaptation own.

But, in the network that merges the PCC framework, also do not customize the method for different PCC rules at present according to the MS access information.Further, also do not determine the method for policing rule at present according to the MS access information.

Summary of the invention

The embodiment of the invention provides a kind of method of definite policing rule, and this method can be determined different policing rules according to the MS access information.

Embodiment one to embodiment three explanation is the embodiment that how determines the PCC rule according to the MS access network information

Embodiment one

In the PCC framework, (comprise WiMAX PCC, 3GPP PCC, 3GPP2 MMD, all PCC frameworks such as TispanIMS) in, when the MS access network, IP is communicated with access network (IP-CAN, IP-Connectivity Access Network) under session foundation or the PCEF change situation, need to set up application layer conversation between PCEF and the PCRF, because in 3GPP, interface between PCEF and the PCRF is the Gx interface, so between session be called the Gx session, PCEF sets up in the request message to increase in the Gx session and carries the MS access network information, and PCRF generates the PCC rule according to receiving the MS access network information that this message carries in conjunction with existing information.

In 3GPP2, interface between PCEF and the PCRF is the Ty interface, so between session be called the Ty session, PCEF sets up in the request message to increase in the Ty session and carries the MS access network information, PCRF generates the PCC rule according to receiving the MS access network information that this message carries in conjunction with existing information.

Fig. 6 is the method flow diagram of preferred embodiment one definite PCC rule of the present invention, and its concrete steps are:

Under step 601～602, the registration of MS access network, IP-CAN session foundation or the PCEF situation of change, PCEF to set up and PCRF between application layer conversation, PCEF sends CCR message to PCRF, application layer conversation (Gx Session or Ty Session) is set up in request, carry the access network information of MS in the CCR message, this access network information is NAP or Access Network Code.

After step 603, PCRF receive this CCR message,, generate the PCC rule according to some information of current mechanism access network information in conjunction with the MS that carries.

How generating the PCC rule can be according to the strategy decision that is provided with.For example: at PCRF the access network information of MS, some information of current mechanism and the corresponding relation between each PCC rule three are set in advance, generate the PCC rule according to corresponding relation, in the PCC rule, have and how to charge, how charging is identified and how to control information such as charging.

Step 604, PCRF return CCA message and give PCEF, carry the PCC rule in the message.

Step 605, PCEF carry out and receive the PCC rule that CCA message is carried.

Embodiment two

In the PCC framework, when the MS access network, under IP-CAN session foundation or the PCEF change situation, to set up Gx Session or Ty Session between PCEF and the PCRF, in setting up Gx Session or Ty Session process, PCRF sets up in session and points out in the response message that PCEF will report the MS access network information to change incident, when MS moves the access network information variation that causes MS when switching, PCEF will report the MS access network information to change the access network information that incident reports MS simultaneously, after PCRF determines the PCC rule according to the MS access network information that reports, in response message, issue this PCC rule, PCEF carries out the PCC rule that issues, Fig. 7 reports the MS access network information to change the method flow diagram of incident for preferred embodiment two of the present invention issues, its concrete steps are:

Step 701, when MS access network, IP-CAN session set up or the PCEF change situation under, PCEF to set up and PCRF between Gx Session or Ty Session, PCEF sends CCR message to PCRF, Gx Session or Ty Session are set up in request, carry the access network information of MS in the CCR message, this access network information is NAP or Access Network Code.

After step 702, PCRF receive this CCR message, according to some information of current mechanism access network information in conjunction with the MS that carries, generate the PCC rule, PCRF has indicated PCEF and need report the MS access network information to change incident in the PCC rule, PCRF returns CCA message and gives PCEF, carries the PCC rule in the message.

Fig. 8 changes the method flow diagram of incident for preferred embodiment two of the present invention reports the MS access network information, and its concrete steps are:

Step 801, because MS moves, process such as re-authentication takes place or other situation causes when the MS access network information changes, include but not limited to that NAP or Access Network Code change, PCEF gives PCRF by CCR information reporting access network information change incident.CCR message except that existing content, the content of also carrying as shown in Table 1:

AVP	The value of AVP	Classification
AVP	The value of AVP	Classification	Event-Trigger	Increasing a value in existing Event-Trigger AVP indicates access network information to change incident.Can increase the Access_Network_Change value during specific implementation finishes.	Newly-increased
Access network information	The value of access network information is NAP or Access Network Code	Newly-increased	Event-Trigger		Newly-increased

Table one

Be that CCR message is carried the more revaluate that MS information changes event identifier and MS access network information.

After step 802, PCRF receive this CCR message,, regenerate the PCC rule according to some information of current mechanism more revaluate in conjunction with the MS access network information that carries.

In embodiments of the present invention, the PCC rule that PCC rule and the PCEF that regenerates carried out for MS can be different, also can be identical, under same case, the more revaluate that shows the MS access network information does not influence the PCC rule, after this moment, PCRF received that the MS access network information changes event identifier, might not be with the PCC rule downloading that regenerates.

Step 803, PCRF return CCA message and give PCEF, carry the PCC rule in the message.

After step 804, PCEF receive CCA message, carry out the PCC rule of carrying.

Embodiment three

In embodiments of the present invention, the WiMAX network adopts the PCC framework with the IMS network integration time, as shown in Figure 9, Fig. 9 is embodiment of the invention WiMAX network adopts the PCC framework with the IMS network integration time a schematic diagram, and this schematic diagram is actually the schematic diagram of prior art.

As shown in the figure: this network comprises that SFM, SFA, agency (Agent), PCRF and AF connect successively.In this framework, the WiMAX network has been introduced the Agent functive, the introducing of this functive mainly is in order not change the Gx interface of original PCC framework, Gx interface between PCEF and the PCRF be do not support ambulant, promptly in IP-CAN conversation procedure, PCEF and PCRF can not move, and Gx session between the two keeps always.When the WiMAX network is introduced the PCC framework, PCEF is put into ASN-GW (being SFA in the drawings) entity to be realized, and for same MS, along with moving of MS, ASN-GW can change, in order not change existing PCC framework and to adapt to the WiMAX network characteristics, so proposed this functive of Agent, the main effect of this functive is to transmit the Gx interface message, the variation of shielding SFA, promptly shield the conversion of ASN-GW, have an interface to be referred to as R3 or R3-PCC interface between Agent and the SFA, different with the Gx interface of PCC framework is R3 or R3-PCC interface allows that PCEF can change in IP-CAN Session process.By Agent, can realize: use existing Gx interface between Agent and the PCRF, at PCRF, Agent is exactly a PCEF that can not move, use R3 or R3-PCC interface simultaneously between Agent and the SFA, SFA is an entity of carrying out the PCC rule in fact, and SFA can move variation.From high-level angle, can regard SFA and Agent as a PCEF jointly, so just meet the regulation of former PCC framework fully.

On the basis of framework shown in Figure 9, in the R3 Session or the Gx Session process between R3-PCC Session and Agent and the PCRF that set up between SFA and the Agent, CCR message is carried the access network information of MS, its method as shown in figure 10:

Step 1001, SFA send CCR message to Agent, and indication R3 Session or R3-PCCSession set up, and CCR message is carried the access network information of MS.

In embodiments of the present invention, SFA also can send other message of the access network information that carries MS, be used for substituting CCR message, as Policy-Decision message, Resource-Reservation message, Location-Update message, qos policy request message or charging regulation request message etc., so long as the bearer messages between SFA and the Agent gets final product.

In embodiments of the present invention, the entrained content of Diameter CCR message is as shown in table 2:

AVP	The value of AVP	Classification
AVP	The value of AVP	Classification	Access network information	NAP or Access Network Code	Newly-increased

After step 1002, Agent receive CCR message, judge self whether user session information of store M S, as Session-ID, if not, then execution in step 1003;

If, judge again that then the MS access network information in the user session information of store M S is whether consistent with the entrained MS access network information of CCR message, if, execution in step 1005; If not, execution in step 1003 then.

Step 1003, Agent send the CCR message of the access network information that carries MS to PCRF.

In embodiments of the present invention, the entrained content of CCR message is as shown in Table 3:

Table three

After step 1004, PCRF receive CCR message, generate the PCC rule and return to Agent in CCA message according to the access network information of the MS that carries and the information of current mechanism, the PCC rule of carrying in this message can point out to report the MS access network information to change incident.

Step 1005, Agent return CCA message and give SFA, and this message is carried the PCC rule.

In embodiments of the present invention, SFA also can send other message of carrying the PCC rule, be used for substituting CCA message, as Policy-Decision message, Resource-Reservation message, Location-Update message, qos policy request message or charging regulation request message etc., so long as the bearer messages between SFA and the Agent gets final product.

After step 1006, SFA receive CCA message, carry out according to the PCC rule of carrying.

On the basis of framework shown in Figure 9, MS moves and causes that Agent can report access network information to give PCRF when access network information changed.Its detailed process is as shown in figure 11:

Step 1101, MS move, the re-authentication process is finished or other situation causes that SFA changes, and SFA will set up the application layer conversation with Agent, sends CCR message to Agent, carries the MS access network information, and indication R3 or R3-PCC Session set up.

In the present embodiment, SFA can be the SFA after MS switches, the SFA under when SFA that MS networks for the first time or MS network re-entry etc.

In embodiments of the present invention, SFA also can send other message of carrying the PCC rule, is used for substituting CCR message, so long as the bearer messages between SFA and the Agent gets final product.

In embodiments of the present invention, CCR message carry increase content as shown in Table 4:

Table four
