Description
Technical field
The present invention relates to mobile communication field more particularly to a kind of method and systems for managing data flow.
Background technique
1. framework explanation
Fig. 1 is third generation partner program (3GPP, 3rd Generation Partnership Project) definition
For the strategy and charging control architecture (PCC, Policy and ChargingControl) schematic diagram of mobile network.Each reality
Body function is described below:
PCRF (Policy and Charging Rules Function, "Policy and Charging Rules Function) includes for business
Business data flow formulate resource control scheme, including QoS (Quality of using Internet resources in transmission process
Service, service quality) control strategy and charging control strategy.
PCEF (Policy and Charging Enforcement Function, strategy and charge execution function) is used for
PCC rule that is that PCRF is issued or being pre-configured on PCEF is executed, the IP packet of transmission over networks is detected, identifies the IP
The business data flow that message is subordinate to, and QoS and charging control are provided to business data flow.
(Bearer Binding and Event Report Function's BBERF reports achievement in bearing binding and event
Can) be mainly used for detecting the IP packet of transmission over networks, and IP packet is mapped to corresponding carrying according to rule and is led to
On road.BBERF also executes reporting for carrying dependent event, such as when access network switching is lost or occurred in carrying,
It requires for corresponding event to be reported to PCRF, request PCRF carries out corresponding decision.
TDF (Traffic Detection Function transmits detection function) will test for executing application detection
Application message be reported to PCRF.It can also realize tactful to using implementation strategy using being issued according to PCRF to what is detected
Control, such as gate, bandwidth limitation collects using redirection and reports charge information etc. to charge system.
SPR (Subscription Profile Repository, user-subscribed database) is used to save user's signing
Business information works out PCC rule for PCRF and provides necessary user signing contract information.OCS (Online Charging System,
Online charging system) and OFCS (Offline Charging System, off-line accounting system) be respectively used to offline and online meter
Take.
User establishes IP-CAN session when accessing network between PCEF and PCRF, commenced business for the user
Cheng Zhong, PCRF issue the QoS and charging policy for business data flow to PCEF.PCC provides QoS and charging control to business
Process is described below:
When user commences business, the application message that business information or TDF will test is reported to PCRF by AF, institute
It states and contains five-tuple and other such as service/application type information in service/application information.PCRF according to the business/
Application message formulates PCC rule for data flow, and the PCC rule includes that (SDF Template, that is, wrap business datum flow template
Information containing five-tuple), service/application mark authorizes QoS and bandwidth (including QCI, MBR, GBR), charging policy etc..PCRF will
The PCC rule is handed down to PCEF.PCEF executes bearing binding according to QCI, if had in QCI and the PCC rule of carrying
QCI is corresponding, then the PCC rule is tied in the carrying；If the QCI in QCI and the PCC rule not carried is corresponding,
PCEF is initiated and the matched carrying of the QCI is established, and the PCC rule is tied in the carrying.After bearing binding is completed,
Just establish the corresponding relationship of PCC rule and carrying.PCC rule with identical QCI can be tied in the same carrying, i.e.,
Multiple business data flows can share the same carrying.Hereafter when data message passes through PCEF, PCEF is by the data message
SDF Template on five-tuple and carrying is matched.When with wherein SDF Template matching, it is known that the data
Message is which PCC rule control, further according to the binding relationship of PCC rule and carrying, is further known to data message use
Which carrying.To provide corresponding QoS and Bandwidth guaranteed for the data message, while according to charging policy, collecting the data
The charge information of message, and it is reported to charge system.
Above-mentioned carrying is divided into GBR carrying and non-GBR carrying.Wherein GBR carrying be provided for business data flow it is absolute
QoS and Bandwidth guaranteed are bound to provide according to the QoS and bandwidth resources of authorized appropriation for it using the data message of the carrying
Quality of service guarantee, even if in the case where resource occurs for network using anxiety, it will not be by other data message preempting resources.
Non-GBR carrying is that opposite QoS and Bandwidth guaranteed are provided for business data flow.Business datum in all non-GBR carryings
(information is the signing bandwidth that all Non-GBR business that user carries out are shared to the shared APN-AMBR of stream, in IP-CAN
When session establishment, it is handed down to PCEF).When Internet resources enough can be according to the authorization QoS and bandwidth of each business data flow points
Described in dispensing when business data flow, QoS and Bandwidth guaranteed can be provided for it, when Internet resources occur using anxiety
It waits, the business data flow will execute resource according to QCI and seize.It therefore can not be from network using the business of non-GBR carrying
Obtain reliable QoS and Bandwidth guaranteed.
The case where foregoing description is during user commences business/applies, and is industry using PCC framework shown in FIG. 1
Business/application provides the process of QoS and charging control, using the above process connect controlled business data flow five-tuple can
It is fitted in SDF Template, therefore dedicated GBR or non-GBR carrying transmission can be used.However actual conditions are also
All SDF Template can not be matched in the five-tuple information and PCEF of some business data flow, at this moment according to existing
Standard definition, operator can abandon this partial service data flow, or establish one and be configured with wildcard five-tuple
Default bearing transmits this partial service data flow.Default bearing is also Non-GBR type, i.e., is not appointing using the carrying
What data flow provides absolute QoS and Bandwidth guaranteed.It is dedicated using Non-GBR using the business data flow and other of default bearing
The business data flow of carrying shares APN-AMBR.
The process of 2.TDF realization charging
When deploying TDF in network, there is a problem of charging inaccuracy in charging.With downstream data flow, (network is sent
To user) for, Fig. 2 is the schematic diagram that PCEF handles data flow in the prior art, when the data flow is with the rate of 200kb/S
When passing through TDF, the ADC rule that TDF is issued according to PCRF detects the data flow, identifies application, and according to TDF
On control strategy, allow the data flow to pass through, and record flow information, be reported to charge system.But when the data flow to
When up to PCEF, five-tuple and SDF the template matching of the data flow, PCEF implement to control according to corresponding PCC rule to it
System carries out speed limit, and flow becomes 150kb/s, and leads to packet loss.Since TDF is not aware that the stream by being limited when PCEF
Speed leads to packet loss, and then the flow on TDF is caused to be greater than the flow on PCEF.When charge in this case to user,
Charging should be carried out according to practical received flow (flow i.e. on PCEF after packet loss), it is clear that TDF is reported to charge system
Flow be it is inaccurate, carry out charging, the problem of necessarily leading to overcharge according to this partial discharge.
For above-mentioned inconsistent in TDF and PCEF control for same data stream, so cause dosage (such as flow, when
Between etc.) inconsistent, the situation of charging inaccuracy is generated, existing implementation method proposes a kind of solution to this:
(1) all SDF Template on PCEF are reported to TDF by PCRF
(2) when data flow passes through TDF, when being detected, TDF is by the five-tuple information and SDF Template of the data flow
Matching:
And if all SDF Template are mismatched, and illustrate do not have corresponding PCC rule control number on PCEF
According to stream, therefore the dosage for flowing through TDF is consistent with the dosage flowed through on PCEF, not the situation of accounting fee inaccuracy.TDF in this case
Directly dosage information is reported to charge system.
If matched with SDF Template therein, illustrate there is corresponding PCC rule control data flow on PCEF,
It is inconsistent to be then likely to result in dosage of the data flow on TDF and PCEF.
(3) in step (2) matched situation, the corresponding SDF Template of the data flow is reported to PCRF by TDF.
(4) PCRF requires PCEF to report the dosage information of the corresponding data flow of SDF Template, and by dosage information
It is handed down to TDF.
(5) TDF carries out dosage correction, such as TDF compares the dosage collected on TDF and the dosage collected from PCEF is (logical
Cross PCRF and be reported to TDF), if the dosage on TDF is greater than the dosage on PCEF, the PCEF dosage collected is reported to by TDF
Charge system, the dosage that otherwise TDF oneself is collected are reported to charge system.
In the above-mentioned control process to data flow, in order to achieve the purpose that accurate billing, PCRF needs constantly monitoring
Dosage on PCEF, and need to pass to TDF by PCRF, or monitor dosage on TDF and pass to PCEF by PCRF, with
Dosage correction is carried out, realizes accurate billing.This transmit on Gx interface (PCEF and PCRF), Sd interface (TDF and PCRF) is used
The mode of amount when having mass data stream in a network, will lead to frequently transmit and handle dosage information, in this way will certainly
The processing load for increasing system equipment, influences network stabilization.
Whether above-mentioned implementation also has phase by the stream of TDF by the five-tuple identification of business data flow on PCEF
The control strategy answered.If all SDFtemplate are mismatched on the five-tuple and TDF of the stream, then it is assumed that the stream exists
Not by policy control on PCEF, it would not also lead to the situation of charging inaccuracy on TDF.If with SDF Template therein
Matching, then it is assumed that the stream is also required to carry out policy control on PCEF, to need to carry out dosage correction to the stream, can be only achieved
The purpose of accurate billing.
And this implementation does not account for the case where business data flow is transmitted using default bearing.According to Jie of front
It continues, all uses wildcard five-tuple using the business data flow that default bearing transmits, i.e., the five-tuple all one of all streams in the carrying
Sample.When the QoS of network and bandwidth resources occur nervous, the business data flow on default bearing and all non-GBR carryings is all
It carries out resource to seize, equally will cause partial data stream packet loss on PCEF in this way.When the stream of packet loss is on default bearing
When stream, since these streams use the five-tuple of wildcard, just cannot be distinguished according to the prior art is which business data flow occurs
Packet loss.Therefore the accurate billing to business data flow can not be just realized using the prior art when this happens.
