US 2014/0237572 A1 · PORTAL AUTHENTICATION METHOD AND ACCESS CONTROLLER

Abstract

In a portal authentication method, a DHCP request message sent by a terminal is received by an AC. In response to finding that a user of the terminal is an unauthenticated user, a private network IP address is assigned to the terminal. After portal authentication of the terminal is finished, a wireless connection of the terminal is terminated by the AC. When a DHCP request message sent by the terminal again is received, a determination that the user of the terminal passes the authentication is made by the AC, a public network IP address is assigned to the terminal, and an accounting request message is sent to a RADIUS server. After finding that the terminal is offline, an accounting stop message is sent by the AC to the RADIUS server, the wireless connection of the terminal is disconnected, and the public network IP address is released.

Dependent claims

A portal authentication method, comprising:

receiving, by an Access Controller (AC), a Dynamic Host Configuration Protocol (DHCP) request message sent by a terminal, and in response to finding that a user of the terminal is an unauthenticated user, assigning a private network IP address to the terminal;
after portal authentication of the terminal is finished, disconnecting, by the AC, a wireless connection of the terminal;
when receiving a DHCP request message sent by the terminal again, determining, by the AC, that the user of the terminal passes the authentication, assigning a public network IP address to the terminal, and sending an accounting request message to a Remote Authentication Dial In User Service (RADIUS) server;
and
after finding that the terminal is offline, sending, by the AC, an accounting stop message to the RADIUS server, disconnecting the wireless connection of the terminal, and releasing the public network IP address.

2 more elements

An Access Controller (AC) comprising:

a processor;
and
a memory;
wherein the processor is to communicate with the memory, and to execute machine readable instructions stored in the memory;
wherein the memory stores machine readable instructions which are executable by the processor to:
receive a Dynamic Host Configuration Protocol (DHCP) request message sent by a wireless terminal, in response to finding that a user of the terminal is an unauthenticated user, to assign a private network IP address to the terminal;
when the portal authentication process of the terminal is finished, disconnect a wireless connection of the terminal;
when a DHCP request message sent by the terminal again is received, determine that the user of the terminal passes the authentication, assign a public network IP address to the terminal, send an accounting request message to a Remote Authentication Dial In User Service, RADIUS, server;
and
when the terminal is found to be offline, send an accounting stop message to the RADIUS server, disconnect the wireless connection of the terminal, and release the public network IP address of the terminal.

7 more elements

A portal authentication system, comprising:

a terminal;
an Access Controller (AC);
and a Remote Authentication Dial In User Service (RADIUS) server;
wherein the terminal is to send a Dynamic Host Configuration Protocol (DHCP) request message to the AC;
wherein the AC is to receive the DHCP request message sent by the terminal, and in response to finding that a user of the terminal is an unauthenticated user, to assign a private network IP address to the terminal;
after portal authentication of terminal is finished, to disconnect a wireless connection of the terminal;
when receiving a DHCP request message sent by the terminal again, to determine that the user of the terminal passes the authentication, assign a public network IP address to the terminal, and send an accounting request message to the RADIUS server;
after finding that the terminal is offline, to send an accounting stop message to the RADIUS server, disconnect the wireless connection of the terminal, and release the public network IP address;
and
wherein the RADIUS server is to start accounting for the terminal according to the accounting request message sent by the AC;
and to stop the accounting for the terminal according to the accounting stop message sent by the AC.
