Self-management network access using localized access management
View Patent ↗The invention provides a method and system for locally tracking network usage and enforcing usage plans at a client device. In an embodiment of the invention, a unique physical key, or token, is installed at a client device of one or more networks. The key comprises a usage application and one or more access parameters designated the conditions and/or limits of a particular network usage plan. Upon initial connection to the network, the usage application grants or denies access to the network based on an analysis of the current values of the access parameters. Therefore, network usage tracking and enforcement is made simple and automatic without requiring any back-end servers on the network while still providing ultimate flexibility in changing billing plans for any number of users at any time.
1. A method for managing network access of a device, which is capable of communicating with one or more networks, comprising the steps of:
identifying the device and a secure token as being associated with a user for which network access is to be discontinued;
accessing a serial number associated with the secure token;
adding the serial number to a watch list comprising a plurality of serial numbers, wherein each of the plurality of serial numbers is associated with a corresponding secure token and wherein each corresponding secure token is associated with a user for which network access it to be discontinued;
transmitting the watch list to a plurality of access points on a network, wherein each access point is configured to:
determine whether the device is currently connected to the network based on the serial number; and
disable a network usage feature set associated with the secure token based at least on the determination that the device is currently connected to the network.
2. The method of claim 1 , wherein the secure token comprises a secure tamper-resistant physical token.
3. The method of claim 1 , wherein secure token is configured to be operatively coupled to the device.
4. The method of claim 1 , wherein the secure token is configured to be local to and removably attachable to the device.
5. The method of claim 1 , wherein the secure token is implemented through a USB adaptor.
6. The method of claim 5 , wherein the application comprises a usage application.
7. The method of claim 1 , wherein the secure token is unique to the device.
8. The method of claim 1 , wherein the serial number is stored in the secure token.
9. The method of claim 1 , wherein the secure token comprises authentication information for authenticating the device to the network.
10. The method of claim 1 , wherein the secure token comprises a processor configured to execute an application.
11. A system for managing network access of a device, which is capable of communicating with one or more networks, the system comprising:
a computing apparatus configured to identify the device and a secure token as being associated with a user for which network access is to be discontinued;
a computing apparatus configured to access a serial number associated with the secure token;
a computing apparatus configured to add the serial number to a watch list comprising a plurality of serial numbers, wherein each of the plurality of serial numbers is associated with a corresponding secure token and wherein each corresponding secure token is associated with a user for which network access it to be discontinued;
a computing apparatus configured to transmit the watch list to a plurality of access points on a network, wherein each access point is configured to:
determine whether the device is currently connected to the network based on the serial number; and
disable a network usage feature set associated with the secure token based at least on the determination that the device is currently connected to the network.
12. The system of claim 11 , wherein the secure token comprises a secure tamper-resistant physical token.
13. The system of claim 11 , wherein secure token is configured to be operatively coupled to the device.
14. The system of claim 11 , wherein the secure token is configured to be local to and removably attachable to the device.
15. The system of claim 11 , wherein the secure token is implemented through a USB adaptor.
16. The system of claim 11 , wherein the secure token is unique to the device.
17. The system of claim 11 , wherein the serial number is stored in the secure token.
18. The system of claim 11 , wherein the secure token comprises authentication information for authenticating the device to the network.
19. The system of claim 11 , wherein the secure token comprises a processor configured to execute an application.
20. The system of claim 11 , wherein the application comprises a usage application.
