Problems solved by technology

[0015] It can be seen from the above that the accounting packets of PPP users and L2TP users are different. At this time, if the Radius server only supports PPP-type accounting packets, it will affect the accounting of L2TP users.

Embodiment Construction

[0032] In order to better understand the present invention, the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0033] see figure 1 , the implementation process of charging according to the PPP method when an L2TP user goes online is as follows:

[0034] Step 101, the L2TP user normally accesses the LAC (L2TP Access Concentrator, L2TP access concentrator);

[0035] Step 102, LAC establishes a tunnel with LNS (L2TP Network Server, L2TP network server), wherein LAC and LNS form an access server;

[0036] Step 103, the LAC establishes a session with the LNS;

[0037] Step 104, the LAC sends the accounting start message to the Radius server: by modifying the Acct-Status-Type attribute in the Accounting-Request message from tunnel-link-start (value 12) to start (value 1) report text to achieve;

[0038] Step 105, the LNS sends the accounting start message to the Radius server: realize the same as above,...

Abstract

The invention discloses a method for charging an L2TP user in a PPP mode. The method comprises the following steps: A, before a user is on-line, if a charging server used by an access server supports charge in a L2TP mode, the user is configured to charge in the L2TP mode on the access server; and if the charging server used by the access server does not support the user to charge in the L2TP mode, the user is configured to charge in the PPP mode and enter step B; B, when the user is online, a tunnel is established, after conversation establishment is completed, the access server changes a tunnel-link-start message into a start message, and transmits to the charging server; and C, when the user is off line, the access server changes the tunnel-link-stop message into a stop message and transmits the stop message to the charging server. The method ensures that the access server can selectively transmits a charging message supported by the charging server according to the functional completeness supported by equipment of the charging server, thereby improving the compatibility of various charging servers.

Description

technical field [0001] The invention belongs to the field of network communication billing, and in particular relates to a method of billing L2TP (Layer 2 Tunneling Protocol, second-layer tunneling protocol) users according to PPP (Point to Point Protocol, point-to-point protocol) through the unification of billing messages. method. Background technique [0002] With the rapid development of network technology, the types of access users become more and more complex. Normally, when the Radius (remote authentication dial-up user service) server charges different types of users, it is inconsistent with the charging packets sent and received between the access devices. In order to realize normal billing, the types of billing packets supported by access devices such as broadband access servers and billing servers such as Radius must be consistent, otherwise, normal billing of users will be affected, such as access devices The sent accounting packets cannot be recognized by the ...
