Abstract

A method and apparatus to control a client in a communication network accessed by the client through a service provider independent of a client controller. In one embodiment, a hardware capable Internet Service Provider (ISP) functions as the communications network service provider. A virtual ISP operates the client controller, leases Internet access time from the hardware capable ISP, and resells Internet services to users. A client accesses the network through a two stage authentication process. First, the hardware capable ISP authenticates the client using a user-provided ID and password. After successfully logging on to the hardware capable ISP, the client automatically sends a start session message containing user identity information to the client controller. In response, the client controller sends a control message to the client authorizing use of the network for a predetermined time period. When the client stops accessing the network, the client informs the client controller using an end session message. If the client wants to access the network beyond the predetermined time period, the client informs the client controller using a continue session message. If no end session or continue session message is received, the client controller assumes that the client is no longer accessing the network at the end of the predetermined time. The client controller can initiate communication with the client by sending other control messages, such as display and download commands.

Claims

1. A method using a client controller to control a client'"'"'s access to use a communications network, the client accessing the client controller through a service provider independent of the client controller, comprising the steps of:

receiving from the client a start session message containing user identity information, the start session message being received by the client controller using the communications network in accordance with a client control protocol, the start session message being sent automatically upon the client being logged on to the service provider independent of the client controller; and

sending to the client a control message to control the client'"'"'s access to use the communications network, the control message being sent from the client controller using the communications network in accordance with the client control protocol and in response to the start session message.

2. The method of claim 1, wherein said step of sending controls whether the client is authorized or denied access to use the communications network.

3. The method of claim 2, wherein the control message is a session authorization message authorizing the client to use the communications network for a predetermined period of time.

4. The method of claim 3, further comprising the step of:

determining if the client is authorized to use the communications network based on the user identity information,

and wherein said step of sending a session authorization message is only performed if the client is authorized to use the communications network.

5. The method of claim 3, further comprising the steps of:

receiving from the client a session continuation message containing the user identity information; and

sending to the client a continuation authorization message, based on the user identity information, authorizing the client to use the communications network for an additional predetermined period of time.

6. The method of claim 5, wherein the continuation authorization message is an additional session authorization message.

7. The method of claim 5, further comprising the step of determining if the client is authorized to continue to use the communications network based on the user identity information, and wherein said step of sending a continuation authorization message is only performed if the client is authorized to continue using the communications network.

8. The method of claim 2, further comprising the step of:

determining if the client is authorized to use the communications network based on the user identity information,

and wherein the control message is a deny session message if the client is not authorized to use the communications network.

recording information about an end of the client session in the usage log if no session continuation message has been received from the client during the predetermined period of time.

15. The method of claim 11, further comprising the steps of:

receiving from the service provider a communications network usage report; and

comparing the communications network usage report with the communications network usage log to determine discrepancies.
