Background technology

Third generation partner program (3rd Generation Partnership Project, referred to as 3GPP) defines for movement The strategy of network and charging control architecture (Policy and Charging Control, PCC), as it is shown in figure 1, each entity function is such as Lower description:

"Policy and Charging Rules Function (Policy and Charging Rules Function, referred to as PCRF) entity is that business packet contains Business data flow use in transmitting procedure Internet resources formulate resource control scheme, including service quality (Quality of Service, referred to as QoS) control strategy and charging control strategy.

Strategy and charge execution function (Policy and Charging Enforcement Function, referred to as PCEF) are used for holding That performing PCR F issues or pre-configured on PCEF PCC rule, detects the IP message of transmission over networks, and identifying should The business data flow that IP message is subordinate to, and business data flow provides QoS and charging control.

Bearing binding and reporting events function (Bearer Binding and Event Report Function, referred to as BBERF) are main It is used for the IP message of transmission over networks is detected, and IP message is mapped on the bearer path of correspondence according to rule. BBERF also performs to carry reporting of dependent event, such as, lose when carrying, or the when of there is access network switching, all needs Corresponding reporting events is carried out corresponding decision-making to PCRF entity, request PCRF entity.

User-subscribed database (Subscription Profile Repository, referred to as SPR) is for preserving the business of user's signing Information, works out, for PCRF entity, the user signing contract information that PCC rule provides necessary.Online Charging System (Online Charging System, referred to as OCS) and off-line accounting system (Offiine Charging System, referred to as OFCS) be respectively used to from Line and online charging.

During user commences business, PCC is that business (being made up of some business data flows) is being transmitted across according to following principle Journey provides QoS guarantee, to improve the business experience of user, raising Internet usage efficiency:

Each business data flow that business packet contains corresponding concrete PCC rule, this business datum defined in PCC rule The QoS resource that can use during streaming.At business data flow formally before bearer network transmits, PCRF entity needs root According to various information be business data flow decision-making and formulate PCC rule.PCRF entity decision-making also formulates the letter of PCC rule institute foundation Breath includes:

The service negotiation information received from AF, this service negotiation information is exactly before user formally commences business and Correspondent Node is consulted The information carrying out described business, such as carry out the qos requirement of described business, the information such as the IP address that used, five-tuple；

The user signing contract information received from SPR, such as comprise the QoS information that user begins to use, then use in user signing contract information Time commencing business in family, business must be in the QoS information that the user of user signing contract information defined can use to the requirement of QoS；

The self-defining strategy of operator of PCRF entity self storage.Roamer and non-roaming subscriber are carried out industry by such as operator Business needs to distinguish and controls, and now can configure the self-defining strategy of operator on PCRF；

The information received from PCEF entity or BBERF.Such as when user is attached to network, PCRF needs to pass through PCEF Or BBERF obtains the information of user access network, it is that user commences business and carries out strategic decision-making for PCRF；

The credit information of user is obtained from OCS.The most once the credit of user is finished, or time not, PCRF entity is with regard to nothing User described in method mandate commences business.

PCRF entity according to above-mentioned information to business data flow decision-making PCC rule, and by PCC rule P CEF entity (as Really there is BBERF in network, then PCRF entity also needs to formulate QoS rule, and is handed down to BBERF).PCEF entity Need the qos requirement according to PCC rule to set up to carry accordingly, and PCC rule is tied in the carrying of correspondence (if Network exists BBERF, is then set up carrying by BBERF according to QoS rule).If network has had and PCC rule Or the carrying that the QoS of QoS rule instruction matches, then be tied to existing holding by described PCC rule or QoS rule In load.

Hereafter, when user commences business, the when that business data flow transmitting on bearer network, gateway device can be according to five yuan Group (being made up of source IP address, source port number, purpose IP address, destination slogan, agreement) will form this business data flow IP message matches corresponding PCC rule/QoS rule, according to PCC rule/QoS rule and the binding relationship of carrying, so that it may To be matched by described business data flow in corresponding carrying, thus provide PCC for business data flow transmission on bearer network QoS guarantee indicated by rule/QoS rule.

There is also other demands during operation, such as certain business, operator wishes that front 10M is freely to make for user , after user uses beyond 10M, it is necessary to collect certain expense；Operator wishes to exist certain class business for another example Use a kind of Bandwidth guaranteed before front 10M, need such business is limited bandwidth after beyond 10M.For above-mentioned scene, Just require that user commences business, while PCRF entity issues PCC rule to PCEF entity, in addition it is also necessary to issue consumption monitoring Instruction, it is desirable to described service implementation consumption is monitored by PCEF, when the flow of described business reaches to monitor required threshold value, Consumption monitoring enforcement will be reported by PCEF entity, in order to PCRF entity carries out decision-making to described business again, produces new control System strategy.

Step A2, PCRF entity issues diameter credit control response to PCEF entity, and (Credit-Control-Answer is referred to as CCA), comprise PCC rule (representing with charging rule definition), require to implement consumption for described PCC rule simultaneously Monitoring, i.e. contain monitoring key, and produce the usage comprising threshold value for monitoring key in PCC rule monitoring information.PCRF entity also can be sent to PCEF entity authorization requests again (Re-Auth-Request, Referred to as RAR) message comprises the instruction of above-mentioned consumption monitoring.

Step A3, corresponding PCRF entity issues RAR message to PCEF entity, then PCEF entity returns to PCRF entity Authorization response (Re-Auth-Answer, referred to as RAA) message again.

Step B, after PCEF entity receives the PCC rule that PCRF entity issues, installation rule.Simultaneously to PCC rule Corresponding business data flow (i.e. business data flow 1 and business data flow 2) implements consumption monitoring.

Step C1-C2 is the process that PCEF entity reports consumption to monitor.

Step C1, when PCEF entity reaches, to the accumulative consumption that Monitoring Key monitors, the threshold value that step A2 issues, PCEF entity carries out consumption supervision and reporting.PCEF entity sends CCR message to PCRF entity, carries Usage Monitoring Information, wherein contains above-mentioned Monitoring Key, comprises in addition accumulative consumption and (uses Used-Service-Unit table Show).

Step C2, PCRF entity returns CCA response to PCEF entity.

Step D, according to the accumulative consumption reported, the PCRF entity business to utilizing this monitoring key to carry out consumption monitoring Data stream (i.e. business data flow-1 and business data flow-2) reformulates corresponding control strategy.

Step E1-E2 is the process that PCRF entity reformulates policy distribution.

Step E1, PCRF entity issues RAR message to PCEF entity, re-issues control plan for business data flow 1 and 2 Slightly.

Step E2, PCEF entity returns response to PCRF entity.

Above-mentioned consumption monitoring mechanism so that network becomes more flexible to the control of business.But operation during, there is also as Lower demand, such as operator initially wish that one group of business data flow is implemented consumption monitoring (is described one group of business datum flow point Join identical monitoring key, and be this monitoring key allocation threshold, the such as business datum shown in flow chart 2 Stream 1 and business data flow 2), this situation is referred to as group consumption monitoring by us.Group consumption is being monitored in implementation process, if Need business data flow therein is cancelled consumption monitoring, will the consumption monitoring of this business data flow from above-mentioned group of consumption monitoring Cancel, utilize existing consumption supervision and reporting mechanism to there is no method and solve the demand.Industry in monitoring additionally for enforcement group consumption Amendment is implemented in the consumption monitoring of business data stream, or is added by a new business data flow in described group of consumption monitoring, utilizes existing When having consumption monitoring mechanism to solve the problems referred to above, it is achieved complicated, have influence on systematic function.
