Description

Broadband user's caller charging method

Technical field

The present invention relates to the communications field, particularly relevant a kind of broadband user's caller charging method.

Background technology

Adopting the charging method of user and access interface binding is the common method that present telecom operators carry out the xDSL broadband charging, and it can solve the problem of account takeover, because customer position information also can be used to charge.At ATM (Asynchronous TransferMode, asynchronous transfer mode) DSLAM (Digital Subscriber Line AccessMultiplexer, the DSL access and multiplexing device) in, authentification of user can pass through ATM PVC (Permanent Virtual Connection, the permanent virtual connection) information is come the access interface of consumer positioning, yet, in IP DSLAM (based on the DSL access device of IP technology), be difficult to allow BAS Broadband Access Server (BAS) initiatively discover user's port information.At present, under general situation, charging can realize by following method: 1. VLAN of each user; 2. dual VLAN sign; 3. adopt a special agreement.

Wherein, VLAN of each user (Virtual Local Area Network, VLAN) is also adopted by some telecom operators, because the user can be identified by the VLAN ID in user's traffic, yet this solution has following weak point:

At first, it has changed the convergence-level network of operator, and usually, low and middle-grade ethernet terminal switches only support less than 1024 or be limited to the VLAN of 128-256 that it needs operator's upgrading convergence-level network to satisfy the demand of VLAN.

Secondly, a lot of configurations are introduced into convergence-level network, BAS and IP DSLAM:

■ is a lot of, and configuration task is introduced into aggregation network, realizes that these VLAN configuration tasks are pretty troublesome.

The a lot of IPDSLAM of ■ can only support VLAN such as the AN2000B less than 1K.

Can ■ BAS support that 4K VLAN also is a problem.

Dual VLAN sign remains not standardized as yet technology, and it can reduce the VLAN configuration task of aggregation network, also can reduce the VLAN degree of depth requirement to IPDSLAM.Yet also there are some shortcomings in this solution:

The Ethernet switch interconnection of the dual VLAN sign of the different manufacturers' of ■ application is still a problem.

■ does not support the middle Ethernet switch of dual VLAN identification technology can think that dual VLAN sign message is a big message (surpassing the message length that switch is supported) and abandon it.

■ needs BAS to support.

■ needs the hardware supports of IP DSLAM.

As for certain protocol, one of them is by Guangdong Telecom science and technology research institute called after VBAS.IP DSLAM can report to BAS with user port information passively.Yet, revise the instability that BAS may cause system.

Therefore how realizing the caller charging of IP DSLAM and not revising BAS is a difficult point.Tell about traditional implementation method below: operators such as present China Telecom have adopted ADSL (ADSL (Asymmetric Digital Subscriber Line)) technology to open the broadband user in large quantities, authentication and accounting technology commonly used comprises PPPoE (point to point protocol of propagating on the Ethernet), 802.1x, or web authentication, wherein the PPPoE technology is the most general.

Please refer to Fig. 1, this is a flow chart that authenticates by PPPoE in existing network, and there are user, IP DSLAM (IP-based Digital Subscriber Line Access Multiplexer), BAS (BAS Broadband Access Server) and charging service platform in the each side that wherein relates to.The flow process that authenticates by PPPoE in existing network is as follows: step 101 is that PPPoE finds the stage, sets up a pppoe session in this stage between BAS and user PC.Step 102 is carry out the point-to-point protocol parameter PPP LCP (point-to-point connection control protocol) stage mutual.In the step 103, the user initiates point-to-point protocol authentication request (sending with PAP password indentification protocol form).In the step 104, IP DSLAM is left intact and only information is transparent to BAS.Following step 105, BAS encapsulation username and password request charging service platform is done authentication.The authentication of charging service platform is passed through in the request of step 106 return authentication.In the step 107, BAS sends point-to-point protocol authorization response information notification authentication to IP DSLAM to be passed through.IP DSLAM is simple transparent transmission response message in step 108

Give the user.PPP IPCP (IP control protocol) stage begins the end of step 109 point-to-point protocol authorization phase simultaneously.

After authentication, carry out next step charging flow.The process of charging flow can be referring to Fig. 1.At first the PPP ipcp phase is finished in step 110.In the following step 111, BAS sends billing information request to begin to charge to the charging service platform, whether BAS detects the user by PPPLCP (Link Control Protocol) echo (Echo) mechanism or BAS approval (acknowledges) mechanism online, BAS stops to charge with notice charging service platform to the charging service platform by sending PPPoEPADT (The PPPoE Active Discovery Terminate, termination messages).The charging identifier here is NAS-PORT (Network Access Server-PORT, a dialup server port) attribute.The charging service platform is responded the request of charging in the step 112.

This traditional charging identifier that method adopted is NAS-PORT, need make amendment to existing online BAS equipment disposition, tends to so the normal operation of existing network is brought bigger risk.How utilizing initiatively report of user information of DSLAM equipment, and BAS equipment is not done any change, reduce risk to greatest extent, to reach the purpose of plug and play, is one of problem of present operator care.

Summary of the invention

The object of the present invention is to provide a kind of broadband user's caller charging method, to overcome above-mentioned the deficiencies in the prior art, solving present broadband user's caller charging method need make amendment and the problem that causes risk to produce to the BAS equipment disposition.

For achieving the above object, the invention provides a kind of broadband user's caller charging method, may further comprise the steps: a.IP DSLAM obtains PPPoE PPP PAP authentication request information and PPPoE PPP CHAP Authentication Response information; B.IP DSLAM comes the consumer positioning address according to user MAC (Media Access Control, media interviews control) address; The user name that c.IP DSLAM modification PPPoE PPP PAP authentication request information or PPPoE PPP CHAP Authentication Response information provide; PPPoE PPPPAP authentication request information that d.IP DSLAM will revise or PPPoE PPP CHAP Authentication Response information are delivered to BAS; E.BAS with PPPoE PPP PAP authentication request information and PPPoE PPP CHAP Authentication Response information translation is and the RADIUS attribute of user name corresponding; F.OSS (operation supportsystem, OSS) according to the user name of revising to user's authentication of chargeing.

Above-mentioned modification user name is position (port) information to be added to original subscriber's name become amended user name together, also can be that the user name that original users is used replaces with positional information.The positional information here comprise node number, frame number, groove number, port numbers.The byte length scope of every value is a node number in the positional information: 1～65535, and frame number: 1～255, groove number: 1～255, port numbers: 1～255.

The present invention has walked around BAS, does not need the BAS end is made amendment, and extra configuration task lacks than VLAN of each user and dual VLAN sign.And transparent to client, satisfied the demand that caller is chargeed.Major advantage particularly of the present invention concentrates on the following aspects:

1. to showing BAS without any influence (whole process is not carried out any modification and other extra works to BAS).

2. to existing charge system influence little (DL SAM scheme of the present invention need be revised the workload of account software will be than supporting VBAS to bring the index word much smaller).

3. do not influence VLAN planning (this scheme does not relate to vlan information, can free configure user VLAN).

4. have nothing to do with centralized and distributed authentication form (with the layout of BAS in network).

5. be not subjected to the restriction (frame number---the machine frame sign can independently define) of original hardware machine frame identification means

The present invention is further illustrated below in conjunction with accompanying drawing and embodiment.

Embodiment

Relevant detailed description of the present invention and technology contents, existing as follows with regard to accompanying drawings:

Please refer to Fig. 2, this is a flow chart that authenticates of the present invention, and there are user, IP DSLAM (IP-based Digital Subscriber Line Access Multiplexer), BAS (BAS Broadband Access Server) and charging service platform in the each side that wherein relates to.The flow process that authenticates by PPPoE (point to point protocol of propagating on the Ethernet) is as follows in the present invention: step 201 is that PPPoE finds the stage, sets up a pppoe session in this stage between BAS and user PC.Step 202 is carry out the point-to-point protocol parameter PPP LCP stage mutual.In the step 203, the user initiates point-to-point protocol authentication request (sending with PAP password indentification protocol form).In the step 204, IP DSLAM obtains PPP authentication information (PAP, password authentication protocol) and by adding or replacing customer position information and revise user name, will change amended user name then and send.

Following step 205, BAS encapsulates amended user name request charging service platform and does authentication.After the charging service platform authenticates amended user name, in the request of step 206 return authentication.In the step 207, BAS sends point-to-point protocol authorization response information notification authentication to IP DSLAM to be passed through.IP DSLAM simple transparent transmission response message in step 208 is given the user.PPP IPCP (IP control protocol) stage begins the end of step 209 point-to-point protocol authorization phase simultaneously.

After authentication, carry out next step charging flow.The process of charging flow can be referring to Fig. 2.At first the PPP ipcp phase is finished in step 210.In the following step 211, BAS sends billing information request to begin to charge to the charging service platform, whether BAS detects the user by PPP LCP echo mechanism or BAS approval mechanism online, and BAS stops to charge with notice charging service platform to the charging service platform by sending PPPoE PADT.The charging identifier here changes into based on user name rather than NAS-PORT attribute.The charging service platform is responded the request of charging in the step 212.

How the subject matter of chargeing is/when IP DSLAM reports to authentication and accounting server with customer position information.If we can report this information on one's own initiative and not need to revise BAS, this clearly helps us to satisfy the demand of operator.

Nearly all Point-to-Point Protocol over Ethernet client software is all carried out the PAP authentication rather than is carried out CHAP (handshake authentication protocol) in PPP authorization phase and BAS.Thus, we can obtain PPP PAP authentication information and revise user authentication information in the user name.BAS carries out the translation of normal PPP to RADIUS (Remote Authentication Dial InUser Service dial-in customer remote authentication service).The user name of revising is used in the subscription authentication meeting, and this user name has comprised the station address with frame, groove and port information.Chargeing also can be according to this user name.This scheme has the following advantages:

■ does not need the BAS end is made amendment, and he has walked around BAS.

■ is transparent to client

■ has satisfied the demand of ABoC

The extra preparation task of ■ is lacked than VLAN of each user and dual sign.

Unique weak point is that authentication and charge system need revision.

From the session of BAS and authentication server, CHAP authentication procedure and PAP similar but can introduce inquiry/response mechanism, this does not influence, and user name of the present invention is revised or displacement.

Between user and BAS, conversation procedure is changed into following pattern:

I) BAS inquiry user

Ii) the user responds inquiry with challenge value (Challenge Value) and title.

Iii) BAS is to inquire that success or failure back and forth should query-responses.

From this angle, we can see that when the PAP authentication, the present invention can revise the CHAP title just as revising user name in the PAP authentication process.Different is the form of CHAP information and PAP information.The ppp protocol of CHAP number be 0xc223 PAP then be 0xc023.

In order to carry out corresponding function, can revise the name field of query-response information with CHAP.

If adopt periodic inquiry, this process also is similarly, because system is only interested in query-response information.

The OSS of one embodiment of the present of invention (operation support system, OSS) flow process comprises:

I) OSS provides and comprises telephone number, node number, frame number, the user profile of slot number and port numbers.

Ii) OSS produces a corresponding number of the account on accounting server.

IPDSLAM obtains the authentication request message (comprising the VLAN label) of following PPPoE PPP PAP:

Biasing: 16 bytes

Length: 11 bytes

Keyword: 0x8864000000000000c02301

Keyword mask: 0xffff000000000000ffffff

IPDSLAM obtains the inquiry back message using (comprising the VLAN label) of following PPPoE PPP CHAP:

Biasing: 16 bytes

Length: 11 bytes

Keyword: 0x8864000000000000c22302

Keyword mask: 0xffff000000000000ffffff

After obtaining this information, DSLAM can location notch item and port numbers, provides the positional information of node number, frame number, slot number and port numbers.Positional information is the character string of the variable-length of maximum 17 minimum 7 bytes, and its form is:

Node number frame number slot number port numbers

Wherein the scope of every value is a node number: 1～65535, and frame number: 1～255, slot number: 1～255, port numbers: 1～255.For node number, if it is 1, insert 1, frame number, slot number and port numbers also are like this.

About each adsl port is revised user name three kinds of possible actions are arranged:

■ revises user name. and the position authentication becomes " positional information # user name " before being added to user name.For example, if user name is aaa, node number is 10, and frame number is 3, and slot number is 10, and port id is 23, and then new user name is " 10#3#10#23#aaa ".

■ replaces user name, and the used user name of original users is replaced by positional information, and for example, if user name is aaa, node number is 10, and frame number is 3, and slot number is 10, and port id is 23, and then new user name is " 10#3#10#23 ".

■ will not revise. this port is not done any operation.

The above introduction only is preferred embodiment of the present invention, can not limit scope of the invention process with this.The variation that is equal to that those skilled in the art in the present technique field are done according to the present invention for example with the improvement that each step makes up and those skilled in that art know among the above embodiment, all should still belong to the scope that patent of the present invention contains.
