Claim:
A method for producing a small window at a client in a broadband data intelligent network, the broadband data intelligent network comprising the client and a portal server, the method comprising: pre-setting a first module and a second module at the client; when a user needs to use a data service of the broadband data intelligent network, obtaining, by the first module, the IP address of the client, and sending the IP address and authentication information input by the user to the portal server; upon receiving a past authentication message from the portal server, the first module making the second module to operate; generating, by the second module, the small window at the client to display access information of the client and provide the user with operation buttons; controlling the user's usage of the data service with the small window, comprising: sending, by the second module, handshaking messages periodically to the portal server, wherein the portal server is configured to: set an off-line reason of the user in a user record to a non-blank value after receiving a forced off-line message from an Integrated Service Control Center (ISCC) or a message from the client indicating the user has actively logged off; check whether an off-line reason of the user in the user record of a database is blank; if yes, return to the second module a handshaking successful response message; and otherwise, return to the second module a handshaking failed response message; and continuing to send handshaking messages periodically to the portal server by the second module in the case of receiving the handshaking successful response message, or ceasing the user's access of the data service and displaying the off-line reason of the user in the small window by the second module in the case of receiving the handshaking failed response message.
