Web Authentication and Accounting Method and System Based on Dynamic Host Configuration Protocol

Abstract

The invention discloses a web authentication and charging method based on Dynamic Host Configuration Protocol (DHCP), which includes: assigning a first IP address to a user terminal according to the current location of the user terminal, and completing the pre-authentication with the first IP address as an identifier User registration; after the first IP address is authenticated, modify the status of the first IP address to pass the authentication, and forward the billing message based on the first IP address; when the user terminal moves, according to the current location of the user terminal, the user The terminal allocates a second IP address, and uses the second IP address as an identifier to complete the user registration before authentication; after the second IP address is authenticated, modify the status of the second IP address to pass the authentication, and the status of the first IP address to be offline, And the charging message is forwarded based on the second IP address. The invention also discloses a DHCP-based web authentication and charging system at the same time.

Description

technical field [0001] The invention relates to authentication and charging technology in the wireless communication field, in particular to a web authentication and charging method and system based on Dynamic Host Configuration Protocol (DHCP, Dynamic Host Configuration Protocol). Background technique [0002] Point-to-Point Protocol over Ethernet (PPPOE, Point-to-Point Protocol over Ethernet) and DHCP are two commonly used dynamic access technologies. Among them, PPPOE has included authentication and accounting functions when it is designed, and it can detect based on the connection Online status can be used as a mainstream technology in home broadband networks. However, DHCP itself has no authentication and accounting, and provides fast access in ordinary LANs. If there is no connection status, it cannot detect user status. [0003] At present, in some business scenarios, such as wifi services provided by operators, DHCP technology is used to realize fast access of users...

AI Technical Summary

Problems solved by technology

In this way, the authentication and accounting system will not be able to know the existence of the new IP address. When the user terminal uses the new IP address to request authentication and accounting, the authentication and accounting system will consider it as an illegal access and reject it.

[0007] 2. The account cannot be authenticated online

[0008] Usually, the user terminal will experience illegal offline problems such as power failure and browser error. Since there is no DHCP connection, even if the user shuts down, the user status on the operator’s equipment will only be cleared when the DHCP lease expires. Therefore, if the lease is not During the expiration period, it will continue to send accounting messages to the remote user dial-in authentication server (RADIUS, Remote Authentication Dial In User Service) to keep online, so that the account will be online for a long time

When the user terminal obtains an IP address again, if the old IP address obtained can directly access the Internet, then when the obtained new IP address is re-authenticated, the "authentication rejected" problem will occur due to the account being online.
