  • Patent number: 7836167
    Abstract: The present invention is directed to a method for monitoring the connection state of users. In the method, when a user accesses a network, the network loads a recognizable browser page on the user terminal and monitors the connection state of the user through message interaction with the browser page. With this method, it can be possible to reliably monitor the online state of the user, so that the authentication and accounting server can accurately charge the user who accesses the network and accepts the services of the network. The handshake mechanism can also be carried out with few or no limitations on the user terminal, thus guaranteeing monitoring of the connection state of users.
