Description
Technical field
The present invention relates to moving communicating field, relate in particular to a kind of method and system of management traffic.
Background technology
1. framework explanation
Fig. 1 is third generation partner program (3GPP, 3rd Generation Partnership Project) define strategy and charging control architecture (PCC, Policy and ChargingControl) schematic diagram for mobile network.Each entity function is described as follows:
PCRF (Policy and Charging Rules Function, "Policy and Charging Rules Function) business data flow that contains for business packet uses Internet resources to formulate resource control strategy in transmitting procedure, comprise QoS (Quality of Service, service quality) control strategy and charging control strategy.
PCEF (Policy and Charging Enforcement Function, strategy and charge execution function) for carrying out PCRF issues or the upper pre-configured PCC rule of PCEF, IP message to transmission over networks detects, identify the business data flow that this IP message is subordinate to, and provide QoS and charging control to business data flow.
BBERF (Bearer Binding and Event Report Function, bearing binding and reporting events function) is mainly used in the IP message of transmission over networks to detect, and IP message is mapped on corresponding bearer path according to rule.BBERF also carries out carrying the reporting of dependent event, and for example, when carrying is lost, or when access network occurs switching, all needs corresponding reporting events to PCRF, and request PCRF carries out corresponding decision-making.
TDF (Traffic Detection Function, transmission measuring ability) detects for carrying out application, and the application message of detection is reported to PCRF.Can also realize strategy that the application to detecting issues according to PCRF to the control of application implementation strategy, for example gate, limit bandwidth, application is redirected, and collects also and reports charge information etc. to charge system.
SPR (Subscription Profile Repository, user-subscribed database), for preserving the signing business information of user, provides necessary user signing contract information for PCRF works out PCC rule.OCS (Online Charging System, Online Charging System) and OFCS (Offline Charging System, off-line accounting system) are respectively used to off-line and online charging.
User, in the time of access network, sets up IP-CAN session between PCEF and PCRF, for the described user process of commencing business, PCRF issues QoS and the charging policy for business data flow to PCEF.PCC provides the process of QoS and charging control to describe as follows to business:
When user commences business, AF reports PCRF by business information or TDF by the application message detecting, has comprised five-tuple and other are as information such as service/application types in described service/application information.PCRF is according to described service/application information, for data flow is formulated PCC rule, described PCC rule comprises business datum flow template (SDF Template, comprise five-tuple information), service/application mark, authorizes QoS and bandwidth (to comprise QCI, MBR, GBR), charging policy etc.Described PCC rule is handed down to PCEF by PCRF.PCEF carries out bearing binding according to QCI, if the QCI correspondence in QCI and the PCC rule of existing carrying is tied to this PCC rule in this carrying; If the QCI correspondence in the QCI and the PCC rule that do not have to carry, the carrying that PCEF initiates and this QCI mates is set up, and this PCC rule is tied in this carrying.After bearing binding completes, just set up the corresponding relation of PCC rule and carrying.The PCC rule with identical QCI can be tied in same carrying, and multiple business data flows can be shared same carrying.After this in the time of data message process PCEF, PCEF mates the SDF Template in the five-tuple of this data message and carrying.When with the coupling of SDF Template wherein, just know which PCC rule of this data message controls, then according to PCC rule and the binding relationship that carries, further know which carrying this data message uses.Thereby for this data message provides corresponding QoS and Bandwidth guaranteed, simultaneously according to charging policy, collect the charge information of this data message, and report charge system.
Above-mentioned carrying is divided into GBR carrying and non-GBR carrying.Wherein GBR carrying is to provide absolute QoS and Bandwidth guaranteed for business data flow, use the data message of this carrying to be bound to provide quality of service guarantee according to the QoS of authorized appropriation and bandwidth resources for it, even use nervous in the situation that in network generation resource, can be by other data message preempting resources yet.Non-GBR carrying is to provide relative QoS and Bandwidth guaranteed for business data flow.Business data flow in all non-GBR carryings is all shared an APN-AMBR (this information is the shared signing bandwidth of all Non-GBR business that user carries out, and in the time of IP-CAN session establishment, is handed down to PCEF).In the time that Internet resources enough can be given described business data flow according to the mandate QoS of each business data flow and allocated bandwidth, can provide QoS and Bandwidth guaranteed for it, in the time that Internet resources generation use is nervous, described business data flow will be carried out resource according to QCI and seize.Therefore use the business of non-GBR carrying to obtain reliable QoS and Bandwidth guaranteed from network.
The situation of foregoing description is in the process of commencing business user/applying, utilize the PCC framework shown in Fig. 1 to provide the process of QoS and charging control for service/application, the five-tuple that utilizes said process to connect in check business data flow can match in SDF Template, therefore can use special GBR or non-GBR carrying transmission.But five-tuple information and the upper all SDF Template of PCEF that actual conditions are some business data flows cannot mate, at this moment define according to existing standard, operator can abandon this part business data flow, or sets up a default bearing that has configured wildcard five-tuple and transmit this partial service data flow.Default bearing is also Non-GBR type, not for using any data flow of this carrying that absolute QoS and Bandwidth guaranteed is provided.Use the business data flow of default bearing and the business data flow sharing A PN-AMBR of other uses Non-GBR dedicated bearer.
2.TDF realizes the process of charging
When having disposed TDF in network, in the time of charging, there is the inaccurate problem of charging.Taking downstream data flow (network sends to user) as example, Fig. 2 is the schematic diagram of PCEF data streams in prior art, when described data flow with the speed of 200kb/S by TDF time, the ADC rule that TDF issues according to PCRF detects this data flow, identify application, and according to the control strategy on TDF, allow this data flow to pass through, and record flow information, report charge system.But in the time that this data flow arrives PCEF, the five-tuple of this data flow and SDF template coupling, PCEF implements to control to it according to corresponding PCC rule, carries out speed limit, and flow becomes 150kb/s, and causes packet loss.Carry out speed limit due to TDF and while not knowing this stream through PCEF, caused packet loss, and then cause the flow on TDF to be greater than the flow on PCEF.When in this case user charge, the flow (i.e. the flow after packet loss on PCEF) that should receive according to reality carries out charging, the flow that obvious TDF reports charge system is inaccurate, carries out charging according to this partial discharge, must cause the problem of overcharge.
For above-mentioned inconsistent at TDF and PCEF control for same data stream, and then cause consumption (for example flow, time etc.) inconsistent, produce the inaccurate situation of charging, existing implementation method has proposed a kind of solution to this:
(1) all SDF Template on PCEF are reported to TDF by PCRF
(2), when data flow is through TDF, while detection, TDF mates the five-tuple information of this data flow and SDF Template:
If do not mated with all SDF Template, illustrate and on PCEF, do not have corresponding PCC rule to control this data flow, the consumption of the TDF that therefore flows through is consistent with the consumption of flowing through on PCEF, not the inaccurate situation of accounting fee.In this situation, TDF directly reports consumption information to charge system.
If the coupling of SDF Template wherein, illustrates and have corresponding PCC rule to control this data flow on PCEF, likely cause the consumption of this data flow on TDF and PCEF inconsistent.
(3) in the situation that step (2) is mated, SDF Template corresponding this data flow is reported PCRF by TDF.
(4) PCRF requires PCEF to report the consumption information of the data flow that this SDF Template is corresponding, and consumption information is handed down to TDF.
(5) TDF carries out consumption correction, the for example relatively upper consumption of collecting of TDF and the consumption (reporting TDF by PCRF) from PCEF collection of TDF, if the consumption on TDF is greater than the consumption on PCEF, the consumption that TDF collects PCEF reports charge system, otherwise the consumption that TDF oneself collects reports charge system.
Above-mentioned to the control procedure of data flow in, in order to reach the object of accurate billing, PCRF needs constantly the consumption on monitoring PCEF, and need to pass to TDF by PCRF, or on TDF, monitor consumption and pass to PCEF by PCRF, to carry out consumption correction, realize accurate billing.This in Gx interface (PCEF and PCRF), the upper mode of transmitting consumption of Sd interface (TDF and PCRF), have mass data stream in network in, will cause the frequent consumption information of transmitting and process, the processing load that will certainly increase like this system equipment, affects network stabilization.
Whether above-mentioned implementation also has corresponding control strategy by the five-tuple identification of business data flow through this stream of TDF on PCEF.If the upper all SDFtemplate of the five-tuple of this stream and TDF do not mate, think that this stream is not subject to policy control on PCEF, just can not cause the upper inaccurate situation of charging of TDF yet.If the coupling of SDF Template wherein, thinks that this stream also needs to carry out policy control on PCEF, thereby need to carry out consumption correction to this stream, just can reach the object of accurate billing.
And this implementation does not consider that business data flow utilizes the situation of default bearing transmission.According to introduction above, utilize the business data flow of default bearing transmission all to use wildcard five-tuple, in this carrying, the five-tuple of all streams is all the same.When the QoS of network and bandwidth resources occur when nervous, the business data flow in default bearing and all non-GBR carryings all will carry out resource to be seized, and can cause partial data stream packet loss on PCEF equally like this.In the time that the stream of packet loss is the stream on default bearing, due to the five-tuple of these stream use wildcards, just cannot distinguish according to prior art is that packet loss has occurred which business data flow.Therefore just cannot utilize when this happens the accurate billing of existing techniques in realizing to business data flow.
