Description
Technical field
The present invention relates to the mobile communication technology field, relate in particular to the charging method in the mobile pocket data business.
Background technology
Along with mobile pocket data business use extensive gradually, how mobile pocket data business is chargeed reasonably and accurately, become the problem of mobile operator common concern.(General Packet Radio Service, GPRS) network configuration can only recognize APN and this rank of PDP Context at customer traffic in current GPRS.And parallel a plurality of business data flows use same PDP Context carrying probably in the reality, and different business then may adopt different charging ways, and the current GPRS network can't satisfy this demand.For example, the user may carry out streaming media service and multimedia messaging service, MMS simultaneously, two business are carried among same APN and the PDP Context simultaneously, but charging regulation difference, as streaming media service according to user data traffic or time-based charging, multimedia messaging service, MMS is then according to event charging, as sending or receive a piece of news.
Can use identical billing solution for dissimilar IP is connected network, need propose a kind of new carrying billing structure, adopt a kind of general billing mechanism based on stream to current GPRS.
At this situation, the present standardized partnership projects of 3G (Third Generation) Moblie (3rd GenerationParmership Project, 3GPP) charging (the Flow BasedCharging that how to realize based on IP stream is being discussed, FBC), for a Packet data service, the user is called business data flow in the use data volume that this business consumed, and (Service Data Flow, SDF), business data flow is the set that a plurality of IP streams are formed.And in a PDP context, can carry a plurality of different business, and therefore can be less than charging granularity based on PDP context based on the charging granularity of IP stream, thus can provide the more charging means of horn of plenty for operator and service provider.
Aspects such as system configuration, functional requirement and message flow to FBC in the TS 23.125 of 3GPP are described.
The FBC system configuration of wherein supporting online charging as shown in Figure 1, the FBC system configuration of supporting offline charging as shown in Figure 2:
The effect of each functional module of FBC system is respectively:
Transmission surface function module (Traffic Plane Function, TPF) be the functional module of carrying packet service data stream, can distinguish the packet data package that belongs to the different business data flow, be used for offline charging information gathering and carry out online credit control, when carrying changes, foundation such as carrying, in modification and the delete procedure, TPF passes through the Gx interface to charging rule functions module (the service dataflow based Charging Rule Function that charges based on Business Stream, CRF) request charging regulation, can carry in the message: the information that the user is relevant with terminal, as Mobile Subscriber International ISDN number MSISDN, IMSI International Mobile Subscriber Identity IMSI, bearer properties is as Qos information and the relevant information of network, as Mobile Network Code MNC, Mobile Country Code MCC MCC.According to the charging regulation that CRF returns, TPF carries out packet filtering on the corresponding service data flow and metering data is collected.
A TPF can be selected according to the identification information of UE by one or more CRF service, can support predefined charging regulation and predefined filter.
CRF is the functional module of preserving charging regulation, support dynamically the charging regulation of (generating some charging regulation data in real time) and static state (use the user charging regulation is unalterable in the data service process, static charging regulation can be activated dynamically) according to professional criterion.TPF information, applied function module (the Application Function of CRF by receiving, AF) information and Online Charging System (OnlineCharging System, OCS) information is as input, be used to choose suitable charging regulation, the charging regulation of choosing sent to TPF in the TPF request or when specific events trigger is arranged
A CRF can corresponding a plurality of TPF.
AF represents all and uses relevant functional module, it can be operator oneself, also can be the third party service provider, AF provides corresponding information to make CRF can select or dispose corresponding charging regulation to CRF, and the information that AF provides comprises: the identification information of business data flow (can wildcard); The information that charging regulation is selected; Application/service identification, application/service billing rule trigger event, stream type (video, audio frequency) (optional), flow rate (optional).
An AF can be corresponding to a plurality of CRF, and AF can select CRF to carry out alternately according to the identification information of UE.
Credit control module (Credit Control, CC) being the functional module of carrying out credit control, only being used for Online Charging System, is to realize by increase new function in existing OCS, by the Ry interface, OCS can provide the input information of charging regulation selection to CRF.
Charging Gateway Functionality module (Charging Gateway Function, CCF) and charging information collecting functional module (Charging Collection Function, CGF) these two functional modules are used for off-line accounting system, can continue to use the realization in the existing GPRS network charging.
If bearer network is a GPRS network, then TPF is positioned at the GGSN place, and AF is a Service Gateway among the PDN, or service server, and AF is exactly P-CSCF in the time of on IMS is carried on GPRS network, and CRF is newly-increased logic module.
Equally, this billing mechanism also can be applied in the network configuration of 3GPP2 and WLAN.
According to existing realization mechanism based on service data flow charge, the implementation procedure of a this billing mechanism of service application as shown in Figure 3:
1, UE sends carrying to TPF and sets up request message.For GPRS, be exactly that GGSN receives Create PDP context Request message;
2, TPF asks charging regulation to CRF, carries the input information that decision CRF selects charging regulation in the message;
3, CRF selects corresponding charging regulation according to the information that obtains, and except carrying and user-dependent information that TPF brings up, this moment, CRF place may also can obtain controlling relevant information from the application of AF and service related information with from the credit of OCS;
4, CRF is handed down to TPF with charging regulation, as replying of charging regulation request message;
5, TPF carries out the action of using or deleting according to the operation indication to charging regulation that CRF provides to corresponding charging regulation;
6, TPF returns carrying to UE and sets up and to accept message, and UE just can be at the carrying transmitting data of having set up.
After execution of step 6, UE just can carry out miscellaneous service request and transfer of data in the carrying of having set up, set up professional the connection such as request with an application server in the network, required data in transport service request process, implementation and the abort process, reception is from information of application server or the like, and the transmission of these data all will take bearing resource.For the bearer network of having realized based on service data flow charge, at the TPF place, difference according to the Business Stream under each packet data package, TPF will use different charging regulations, generate different call details record (Call Detail Record, CDR), be a kind of formative ensemble of communication of the usefulness of chargeing, be used for online charging or offline charging.
Only illustrated that above TPF is to the situation of CRF request charging regulation when carrying is set up, except TPF in the initial foundation of carrying need report some bearer related informations to be used to select the charging regulation to CRF, relate to carrying at bearing modification or deleting load-bearing etc. and use situation about changing, also can cause the variation of corresponding charging regulation, at this moment TPF also needs to initiate the charging regulation request message to CRF, according to selecting, determine whether to implement new charging regulation by CRF from the information of TPF, AF and OCS.
With TPF to the process of CRF request charging regulation mutually independently, AF and OCS also can provide the input information of selecting charging regulation to CRF, wherein the information that provides of AF is professional relevant with application layer, the information that OCS provides is then relevant with the credit of business in the online charging, the CRF charging regulation that certain business data flow carrying is chargeed and be implemented according to the information available comprehensive selection.
At present, according among the standard 23.125v600 to the definition of charging regulation, charging regulation comprise in have:
The charging way of a particular traffic data stream: online charging or offline charging;
When offline charging, be to carry out record by flow, duration or flow and duration;
The charging key;
One or more business datum flow filter;
Priority.
Wherein, filter is to be used for distinguishing the packet data package that belongs to particular traffic data stream, and basic formation is the IP five-tuple, comprises source IP address, purpose IP address, source port number, destination slogan, host-host protocol number or application protocol number.The charging key is used for determining rate.Priority is to be used for determining to use which charging regulation to use when the charging regulation appearance is overlapping.
When implementing a specific transactions, TPF filters the packet data package of this business data flow according to selected charging regulation, generates charge information.May be not only one because be applied in a charging regulation on the business data flow, so TPF need be according to the priority of charging regulation, successively the packet data package of receiving is mated, generate charge information according to that charging regulation that mates most, for the packet data package that does not have on the coupling, use default charging way, be configured by operator, default charging regulation can be to use, also other billing mechanisms can be adopted.
After the charging of realization based on business data flow, according to existing implementation, on the carrying aspect, TPF need filter each packet data package, judge which business data flow is this packet data package belong to, which charging regulation of decision application charges then, this just needs the TPF place to carry out a large amount of matching processs at a high speed, therefore the disposal ability to TPF has proposed very high requirement, in realization, can cause the increase of cost, if disposal ability does not reach certain requirement, can cause the increasing of service delay, thereby reduce service quality.
