Description

Message accounting and method
Technical field
The present invention relates to the communications field, particularly a kind of message accounting and method that is used for communication system.
Background technology
The charging way that present user's access fee is used is more single, in the speech epoch, because access and bundling are tightr, class of business is also few, access means and professional bundle substantially one to one, the expense of the expense of differentiated service and access and carrying not usually when chargeing.
Inserting packetizing, broadband, after the professional variation, insert with professional boundary more and more obvious, even access and business belong to the operation of same operator, at present simple monthly payment, timing charging way long, the meter flow can not satisfy the needs of operation, make the bandwidth resources of access carrier not to be utilized effectively, network planning difficulty, user's expenditure can not embody the value that the user obtains.
On the other hand, Access Network also embodies different value to the user, it is professional that the user experiences sometimes, what experience sometimes is the carrying of data, say it in another way, when the user to service supplier (SP, when serviceprovider) paying, what the user wished to enjoy is the business of paying, and is indifferent to this professional bandwidth that consumes, and at this moment the service supplier access fee that should bear bandwidth is used.When the user not directly when service supplier is paid, the user obtains to be worth by bandwidth consumed, used by the access fee that the user bears bandwidth this moment.
So when providing access service, need segment ability fair differentiated service supplier, access service supplier and user consumption to the charging of access service, and between them, reasonably insert cost allocation to access bandwidth to the user.
The mode of narrow band access has POTS (POTS plain old telephone service, the plain old telephone service system) dials up on the telephone and ISDN 2B+D (ISDN integrated service digital network ISDN, 2B+D is a basic rate interface, wherein B is the digital channel of 64kbit/s speed, D is the digital channel of 16kbit/s speed, the B channel is mainly used in and transmits user profile stream, the D channel is mainly used in the signaling information of transfer circuit exchange, also be used to transmit packet-switched data information) insert, broadband access is on the access means, extensive use at present ADSL (ADSL (Asymmetric Digital Subscriber Line)) arranged, LAN (local area network (LAN)), cable (cable), FTTH (Fiber to the home) from now on, WLAN (WLAN (wireless local area network)), 3G (third generation communication system) etc., the application meeting of broadband access more and more widely.The user need be through the authentication of operator when inserting, and the means of authentication mainly contain at present: PPPoE (point-to-point protocol on the Ethernet, PPP over Ethernet) authentication, web authentication, port binding.After authentication was passed through, operator charges to user's use, and was off line up to the user.
Below, with reference to Fig. 1, existing a kind of charging way is described.
As shown in Figure 1, it has described the last network process of generally held standard Radius (Remote Authentication Dial-InUser Service, a kind of agreement that realizes AAA (checking, mandate, charging)).RADIUS is current widely used a kind of aaa protocol, and its future development trend is the DIAMETER agreement.
At first, in step 101, user's demand of will reaching the standard grade authenticates and is sent to BAS (broadband accessserver, BAS Broadband Access Server is also referred to as BRAS, broadband remote access server), proposes the request of reaching the standard grade;
Then, in step 102, after BAS receives user's request, send authentication request packet, request to iSCP (integrated service control point);
Then, in step 103, iSCP sends corresponding response message to BAS;
If iSCP sends and inserts successful response message in step 103, then in step 104, BAS is configured the user according to the attribute that iSCP beams back; And BAS sends charging starting request message to iSCP in step 105 simultaneously;
Then, in step 106, iSCP beams back corresponding charging response message;
Then, in step 107, in the last network process of user, BAS regularly sends the real time billing request to iSCP;
Then, in step 108, iSCP beams back corresponding charging response message;
If in step 109, the user proposes the request of rolling off the production line, and then in step 110, after BAS receives user's request, sends charging ending request message to iSCP;
Then, in step 111, iSCP beams back corresponding charging response message;
Then, in step 112, after BAS received that the charging of iSCP finishes response message, disconnect user connected, at this moment user offline.
Below, the message format and the attribute commonly used of the Radius message in the superincumbent charging flow are described.
As shown in Figure 2, the radius message format has been described.
When Code=4, this radius message is represented the request of chargeing.When Code=5, this radius message is represented the response of chargeing.
Five kinds of Status Types (Acct-Status-Type) in the charging request message:
Start (1): client (Client) begins to provide service to designated user, the beginning of keeping accounts;
Stop (2): client stops to provide service to designated user, keeps accounts and finishes;
Interim-Update (3): report flow information midway, keep accounts in real time;
Reset-Charge (4): after authentication, iSCP initiatively requires client to change strategy, and client reports flow information.
Client must be sent charging request message (beginning) after receiving and inserting successful message.ISCP if do not receive charging request message (beginning) in the regular hour, then discharges session after sending the successful message of access.When disconnect connecting (comprising aborted), the client request message (stopping) of must initiating to charge.
After iSCP receives charging request message (beginning), the most expensive possible rate according to next metering period, calculate flow (Remanent-Volum) or the duration (Session-Timeout) that allows the user to use according to user balance, if right and wrong prepaid user, the flow (Remanent-Volum) or duration (Session-Timeout) parameter that allow the user to use do not occur, and client need the amount of managing business not monitor.ISCP sends the response of chargeing to the user, comprises duration (Session-Timeout), flow (Remanent-Volum), rate interval switching time (Tariff-Switch-Interval).
The cycle of keeping accounts is that mutual agreement is good in real time, makes the form that can dynamically arrange within the specific limits.Like this can be according to different environmental conditions and different business demand settings in actual networking.The cycle of keeping accounts must be less than the time interval of any twice rate switching in real time.
In table 1, listed the attribute commonly used of Radius message:

3)Session-Timeout
How long this session (connection) can also be used.If this parameter does not occur, then client can not cut off connection because service time is oversize.This value is 0 in the response if charge, and then client reports the request of chargeing (stop) at once, and disconnection connects.
4)Remanent-Volume
How many K bytes this connection can also transmit, and has comprised to receive and send out both direction.If this parameter does not occur, then client can not cut off because the flow that uses is too many and connect.This value is 0 in the response if charge, and then client reports the request of chargeing (stop) at once, and disconnection connects.
5)Tariff-Switch-Interval
Rate will take place after how long crossing to be switched.This duration connects the last transmission request of chargeing from this to begin to count.If this parameter does not occur, then client thinks that rate does not take place to be switched.
Some difference of the message format of Diameter and the expression of attribute and Radius agreement is specifically referring to the related protocol " rfc 3588 Diameter Base Protocol " of diameter.
Prior art is to the mandate that inserts and authenticate fairly perfectly, aspect charging, only provides the charging to flow, duration, is not inserting the lateral areas separate service, thereby is making the charging way dullness, lacks flexibility.

Embodiment
The invention provides a kind of accounting access mode of combination, inserting the IAD of side classifies to business, adopt different charging policy at different business, by using the combination of these strategies, avoided the shortcoming of present single charging way, access carrier can be more accurately according to the operating position charge of resource, and user's expenditure can more objectively reflect the value that the user obtains.Because the flow that inserts is distinguished, access carrier can be distinguished the flow of different business operator and content supplier, thereby the present invention can provide the method for the disbursement and sattlement between access carrier and the service provider.
Be illustrated in figure 3 as the schematic diagram that the user inserts, subscriber equipment is connected with core net with other access device by IAD and enjoys miscellaneous service.The mode that inserts can be wired access, wireless access, optical fiber access etc.IAD among the figure refers to that mainly BAS (BAS Broadband Access Server) equipment, RNC (radio network controller), BSC (base station controller) etc. in wireless in the fixed network is from that nearest access device of core net.The present invention is engaged in classifying in the enterprising industry of this IAD, and produces corresponding ticket writing.
As shown in Figure 4, according to message accounting of the present invention, comprise an adress analysis module 11, a type of service determination module 12 and an accounting module 15.This message accounting is positioned on the access device.All all pass through this message accounting through the data of access device.
The adress analysis module 11 of this message accounting obtains the destination address of upstream message and the source address of downstream message from pass through the message of this message accounting.The result that the adress analysis module will be analyzed sends to accounting module 15.Because adress analysis module 11 is distinguished the business that inserts by the address, therefore can distinguish different service providers and content supplier.
The type of service determination module 12 of this message accounting will be classified by the business of this message accounting, and type of service is classified (such as http, ftp, rtp business etc.), distinguishes dissimilar business.The type of service that this type of service analysis module 12 obtains its analysis sends to accounting module 15.
Accounting module 15 is according to from the address information of adress analysis module 11 with from the traffic type information of type of service determination module 12, search the charging classification chart, definite to the current charging way of passing through the message of this message accounting (access device), and according to corresponding charging way charging.Store the agreement of basis and user signing, the charging policy different with the different service types execution in this charging classification chart to different addresses.In the present invention, this charging classification chart can utilize existing technology static state to dispose on IAD, or arrives IAD by the network management system dynamic-configuration.Shown among Fig. 5 should the charging classification chart example.
As shown in Figure 5, determine the destination address of the upstream message by this message accounting or the source address of downstream message when address analysis module 11 and belong to group of addresses 1, and when type of service determination module 12 determined that the type of service of this upstream message or downstream message is type of service 1, accounting module 15 determined that charging way is monthly payment.Determine the destination address of the upstream message by this message accounting or the source address of downstream message when address analysis module 11 and belong to group of addresses 1, and when type of service determination module 12 determined that the type of service of this upstream message or downstream message is type of service 2, accounting module 15 determined that charging way is for to charge according to communication time.Determine the destination address of the upstream message by this message accounting or the source address of downstream message when address analysis module 11 and belong to group of addresses 1, and when type of service determination module 12 determined that the type of service of this upstream message or downstream message is type of service 3, accounting module 15 determined that charging way is for to charge according to communication flows.
Determining the charging way of current message when accounting module 15 be when chargeing according to communication time, and it is from duration statistical module 14 obtaining communication durations, and charges according to this communication time, the generation keep cost order, and the ticket writing of generation comprises the duration record.
Determining the charging way of current message when accounting module 15 is during according to communication flux accounting, it obtains the corresponding communication flow information from traffic statistics module 13, and charge according to this communication flows information, generating keep cost order, the ticket writing of generation comprises discharge record.
Determining the charging way of current message when accounting module 15 is during according to event charging, it obtains the number of times of corresponding business transaction from incident statistical module 16, and charge according to the number of times of this business transaction, generating keep cost order, the ticket writing of generation comprises the number of times of business transaction.In the present invention, each business transaction is called an incident, for example plays a film.Incident can determine that the foundation of business transaction session indicates the beginning of incident by the conversation procedure of each business transaction, and the end mark of business transaction session the end of the incident of incident.Utilize the business transaction number of times to charge to be mainly used in the situation of utilizing flow or duration to charge of being not suitable for.
When message accounting determined that the charging way of current message is monthly payment, it did not need to obtain information from duration statistical module 14 and traffic statistics module 13 and incident statistical module 16, chargeed according to every month fixing expense.
This message accounting is best on BAS equipment, but also this message accounting can be placed on other network element, will carry the traffic classification charging as long as can and use according to different reference address.
In addition, in this message accounting, message does not require by the order of adress analysis module 11, type of service determination module 12, traffic statistics module 13, incident statistical module 16 and duration statistical module 14, as long as they can analyze the message by this message accounting, and the result notification accounting module 15 that obtains is got final product.
In addition, accounting module 15 can be according to from the address information of adress analysis module 11 with from the traffic type information of type of service determination module 12, and determining to be paid by SP still is by user charges.For example, as shown in Figure 5, determine the destination address of the upstream message by this message accounting or the source address of downstream message when address analysis module 11 and belong to group of addresses n, and when type of service determination module 12 determines that the type of service of this upstream message or downstream message is type of service 2, accounting module 15 determines that charging way is that timing is long, and is paid by SP.The expense that produce this moment, according to using detail record and way of paying (long as timing in this example), (being the service provider corresponding to group of addresses n in this example) collects to corresponding business operator, and do not collect to the user by access carrier.Thereby, realized the disbursement and sattlement method between access carrier and the service provider.
Below, to describe according to charging method of the present invention with reference to Fig. 6, it comprises the steps:
At first, in step 501, obtain the destination address of the upstream message by access device and the source address of downstream message.
Then, in step 502, determine type of service by the message of access device.Obviously, the order of step 501 and step 502 can be put upside down.
Then, in step 503,, charge with reference to the charging classification chart according to step 501 and 502 information that obtain.In addition, charge when needing communication time information when this step, this charging method also comprises the step of adding up communication time.Charge when needing communication flows information when this step, this charging method also comprises the step of adding up communication time.Charge when needing business transaction number of times information when this step, this charging method also comprises the step of statistical service transaction count.
In the present invention, realize chargeing as adopting radius or diameter agreement, last network process is identical with last network process shown in Figure 1, and its difference only is the generation of charging bill in the real time billing process.
When being inconvenient to revise radius agreement or diameter agreement, IAD will need the business of user charges to use statistical information to report iSCP, do not need the business of user charges to use for other, only generate service recorder, gather, charge and clearing for the charge system off-line, do not report iSCP in real time.
In the message of radius agreement or diameter agreement, also can increase the information field of describing professional type of service, use professional charging can distinguish the user more accurately.This information field is as describing with the AVP of diameter (Attribute-Value Pair, property value to), and is as follows:
