Description

The consumption method for supervising of data flow and device, PCEF entity

Technical field

The present invention relates to the communications field, in particular to a kind of consumption method for supervising of data flow and device, PCEF entity.

Background technology

Third generation partner program (3rd Generation Partnership Project; Abbreviate 3GPP as) defined strategy and charging control architecture (Policy and Charging Control to the mobile network; PCC), as shown in Figure 1, each entity function is described as follows:

"Policy and Charging Rules Function (Policy and Charging Rules Function; Abbreviating PCRF as) entity uses Internet resources formulation resource control strategy for the professional business data flow that comprises in transmission course; Comprise service quality (Quality of Service abbreviates QoS as) control strategy and charging control strategy.

Strategy and charge execution function (Policy and Charging Enforcement Function; Abbreviate PCEF as) be used to carry out that PCRF issues or the last pre-configured PCC rule of PCEF; IP message to transmission over networks detects; Discern the business data flow that this IP message is subordinate to, and the QoS and the control of chargeing are provided business data flow.

The IP message that bearing binding and reporting events function (Bearer Binding and Event Report Function abbreviates BBERF as) are mainly used in transmission over networks detects, and the IP message is mapped on the corresponding bearer path according to rule.BBERF also carries out and carries reporting of dependent event, for example loses when carrying, and when the access network switching perhaps takes place, all need events corresponding be reported the PCRF entity, and request PCRF entity is made a strategic decision accordingly.

User-subscribed database (Subscription Profile Repository abbreviates SPR as) is used to preserve the business information that the user contracts, and works out the PCC rule for the PCRF entity necessary user signing contract information is provided.Online Charging System (Online Charging System abbreviates OCS as) and off-line accounting system (Offiine Charging System abbreviates OFCS as) are respectively applied for off-line and online charging.

In the user commenced business process, PCC provided QoS to guarantee according to following principle in transmission course for professional (being made up of some business data flows), to improve user's business experience, improved the Internet resources service efficiency:

The all corresponding concrete PCC rule of each business data flow that business comprises, operable QoS resource when having defined this business datum flow transmission in the PCC rule.Formally before bearer network transmission, the PCRF entity need be the business data flow decision-making and formulate the PCC rule according to various information at business data flow.The information of decision-making of PCRF entity and formulation PCC rule institute foundation comprises:

From the service negotiation information that AF receives, this service negotiation information is exactly before the user formally commences business and the information of carrying out said business of Correspondent Node negotiation, for example carries out the qos requirement of said business, information such as employed IP address, five-tuple;

User signing contract information from SPR receives for example comprises the QoS information that the user brings into use in the user signing contract information, when then the user commenced business, business must be in the operable QoS information of the user of user signing contract information defined to the requirement of QoS;

The self-defining strategy of operator of PCRF entity self storage.For example operator commences business and need differentiation control roamer and non-roaming user, and can dispose the self-defining strategy of operator this moment on PCRF;

Information from PCEF entity or BBERF reception.When for example the user was attached to network, PCRF need obtain the information of user access network through PCEF or BBERF, carried out strategic decision-making for the user commences business for PCRF;

Obtain user's credit information from OCS.In case for example user's credit uses up, when perhaps not enough, the PCRF entity just can't authorize said user to commence business.

The PCRF entity is regular to business data flow decision-making PCC according to above-mentioned information, and with PCC rule P CEF entity (if there is BBERF in the network, then the PCRF entity also need be formulated the QoS rule, and is handed down to BBERF).The PCEF entity need be set up corresponding the carrying according to the qos requirement of PCC rule, and the PCC rule is tied in the corresponding carrying (if there is BBERF in the network, then set up according to the QoS rule by BBERF and carry).If the carrying that has had the QoS of or QoS rule indication regular with PCC to be complementary in the network then is tied to the regular perhaps QoS rule of said PCC in the existing carrying.

After this; When the user commences business; When business data flow transmits on bearer network; Gateway device can match corresponding PCC rule/QoS rule according to the IP message that five-tuple will be formed (being made up of source IP address, source port number, purpose IP address, destination slogan, agreement) this business data flow; According to PCC rule/QoS rule and the binding relationship that carries, just can said business data flow be matched in the corresponding carrying, thereby guarantee for the transmission of business data flow on bearer network provides the indicated QoS of PCC rule/QoS rule.

In the operation process, also have other demands, such as for certain business, 10M supplied that the user is free to be used before operator hoped, when the user use exceed 10M after, just need collect certain expense; Operator hopes certain type of business was used a kind of bandwidth guarantee before preceding 10M for another example, need be to such traffic limits bandwidth after exceeding 10M.For above-mentioned scene, just require the user to commence business, when the PCRF entity issues the PCC rule to the PCEF entity; Also need issue the indication of consumption monitoring; Require PCEF that said service implementation consumption is monitored, when the flow of said business reaches the desired threshold value of monitoring, the PCEF entity will be implemented to report to the consumption monitoring; So that the PCRF entity is made a strategic decision to said business again, produce new control strategy.

The implementation procedure flow process as shown in Figure 2 of consumption monitoring:

Steps A 1-A3 is the PCRF entity issues a process from consumption monitoring indication to the PCEF entity; The rule definition (Charging Rule Definition) that charges in the flow chart is used to describe the PCC rule, i.e. business data flow of a corresponding description of Charging Rule Definition.Monitoring sign (Monitoring Key) is consumption monitoring sign; If having comprised Monitoring Key among the Charging Rule Definition just shows; Need implement the consumption monitoring to this business data flow, be that this Monitoring Key produces a consumption monitor message (Usage Monitoring Information) simultaneously.Usage Monitoring Information has comprised this momtoring key, has also comprised this Monitoring Key corresponding threshold (Granted Service Unit), and the information that comprises is not in addition described owing to have nothing to do with the present invention.From steps A 2, finding out has two business data flows (being Charging Rule Definition-1 and Charging Rule Definition-2); For these two business datum flow distribution identical Monitoring Key, explanation need be implemented the monitoring of same consumption for these two business data flows.Implement the consumption monitoring respectively for these two business data flows if desired; Then need produce Monitoring Key-1 for Charging Rule Definition-1; For Charging RuleDefinition-2 produces Monitoring Key-2; Simultaneously need be for these two Monitoring Key produce Usage Monitoring Information respectively, this situation is not being described here.

Steps A 1, the PCEF entity sends credit control request (Credit-Control-Request abbreviates CCR as) to the PCRF entity;

Steps A 2; The PCRF entity issues credit control response (Credit-Control-Answer to the PCEF entity; Abbreviate CCA as), comprise PCC rule (representing) with charging rule definition, require simultaneously to implement the consumption monitoring for said PCC rule; Be to have comprised monitoring key in the PCC rule, and produce the usage monitoring information that comprises threshold value for monitoring key.The PCRF entity also can send to the indication that comprises above-mentioned consumption monitoring in the authorization requests again of PCEF entity (Re-Auth-Request,, the abbreviate RAR as) message.

Steps A 3, corresponding PCRF entity issues RAR message to the PCEF entity, and then the PCEF entity returns authorization response (Re-Auth-Answer abbreviates RAA as) message to the PCRF entity again.

Step B, after the PCEF entity is received the PCC rule that the PCRF entity issues, installation rule.Simultaneously PCC rule corresponding service data flow (being business data flow 1 and business data flow 2) is implemented the consumption monitoring.

Step C1-C2 reports the process of consumption monitoring for the PCEF entity.

Step C1, when the PCEF entity reached the threshold value that steps A 2 issues to the accumulative total consumption of Monitoring Key monitoring, the PCEF entity carried out the consumption supervision and reporting.The PCEF entity sends CCR message to the PCRF entity, carries Usage Monitoring Information, has wherein comprised above-mentioned Monitoring Key, also comprises accumulative total consumption (representing with Used-Service-Unit) in addition.

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

Step D, according to the accumulative total consumption that reports, the PCRF entity is reformulated corresponding control strategies to the business data flow (being business data flow-1 and business data flow-2) that utilizes this monitoring key to carry out the consumption monitoring.

Step e 1-E2 reformulates the process of policy distribution for the PCRF entity.

Step e 1, the PCRF entity issues RAR message to the PCEF entity, for business data flow 1 and 2 issues control strategy again.

Step e 2, the PCEF entity returns response to the PCRF entity.

Above-mentioned consumption monitoring mechanism makes network become more flexible to the control of business.Yet in the operation process; Also there is following demand; For example operator hopes that initially one group of business data flow is implemented the consumption monitoring (is the identical monitoring key of said one group of business datum flow distribution; And be this monitoring key allocation threshold, for example business data flow shown in the flow chart 21 and business data flow 2), we are called the monitoring of group consumption with this situation.In to group consumption monitoring implementation process, if desired business data flow is wherein cancelled the consumption monitoring, be about to consumption monitoring cancellation from above-mentioned group of consumption monitoring of this business data flow, utilize existing consumption supervision and reporting mechanism still can't solve the demand.Monitor implementation modification for the consumption of the business data flow in the monitoring of enforcement group consumption in addition; Perhaps a new business data flow is added in the said group of consumption monitoring; When utilizing existing consumption monitoring mechanism to address the above problem, realize complicacy, have influence on systematic function.
