Abstract

A method and processing device for controlling the communication of data associated with a user on a network 1 is described, in which the communication of data to and from a user is controlled according to user profile information. In a preferred embodiment, the user profile information is maintained in a database 9 accessible to processing devices 5 providing access to the network 1, and includes a volume allowance for a predetermined time period, a maximum transmission rate and current usage information for the user. Each time a user connects to the network 1, the method determines whether the user is within the volume allowance, and if so, permits access to the network 1. The communication of data is controlled according to the maximum transmission rate. The method may be implemented in software.

Claims

1. A method for controlling the communication of user data associated, at a plurality of network switches on a network, with a user on the network, the method comprising:

in at least one of the plurality of network switches,

accessing user profile information of the user, wherein the user profile information comprises at least a data volume allowance for the user;

monitoring a volume of data used by the user over the network regardless of which of a plurality of devices the user uses to access the at least one of the plurality of network switches;

controlling the communication of user data on the network by permitting said communication of user data through the plurality of switches while the volume of data used by the user is within the data volume allowance for the user, and

preventing said communication of user data if the volume of data used by the user reaches or exceeds the data volume allowance for the user.

2. A method as claimed in claim 1, in which the method further comprises obtaining current usage information for the user from an external database;

comparing the current usage information with the volume allowance for the user, and controlling the communication of user data according to the result of the comparison.

3. A method as claimed in claim 2, in which the volume allowance is a data volume for the user in a time period;

the current usage information includes a current volume for the user, the current volume corresponding to the volume of data associated with the user communicated on the network since the start of a current said time period, and the step of comparing comprises comparing the volume allowance with the current volume for the user.

4. A method as claimed in claim 3, in which, if the step of comparing determines that the current volume is greater than or equal to the volume allowance, the step of controlling comprises preventing data communication by the user until said current time period has expired.

5. A method as claimed in claim 4, in which, if the step of comparing determines that the current volume is less than the volume allowance, the step of controlling comprises permitting the communication of user data associated with the user whilst controlling a data rate.

6. A method as claimed in claim 3, in which, if the step of comparing determines that the current volume is less than the volume allowance, the step of controlling comprises permitting the communication of user data associated with the user whilst controlling a data rate.

7. A method as claimed in claim 6, the step of controlling the data rate comprises controlling the data rate according to a maximum data rate.

8. A method as claimed in claim 6, further comprising:

monitoring, in the at least one of the plurality of network switches, the volume of data associated with the user communicated on the network.

9. A method as claimed in claim 8, further comprising:

periodically determining a new current volume for the user;

comparing the new current volume with the volume allowance for the user, and controlling the communication of user data based upon the comparison.

10. A method as claimed in claim 9, wherein the volume allowance, the current volume, the data rate, the maximum data rate, and the time period are stored in the external database;

and wherein the at least one of the plurality of network switches is configured to communicate with the external database.

11. A method as claimed in claim 10, wherein the at least one of the plurality of network switches is configured to perform the step of monitoring, the method further comprising periodically sending the monitored volume of data for the user to the database for updating the current volume for the user.

12. A network switch associated with a device providing access to a user to a network, the network switch being configured to access user profile information of a user of the device, wherein the user profile information comprises at least a data volume allowance for the user, to monitor a volume of data used by the user over the network regardless of which of a plurality of devices the user uses to access the network switch, and to control the communication of data associated with the user at a plurality of points on the network, wherein the network switch prevents the user from accessing the network when the volume of data used by the user reaches or exceeds the data volume allowance for the user.

13. A method for controlling, at a plurality of points on a network, the communication of user data associated with a user on the network, the method comprising:

in at least one hub on the network,

accessing user profile information of the user, wherein the user profile information comprises at least a data volume allowance for the user;

monitoring a volume of data used by the user over the network regardless of which of a plurality of devices the user uses to access the at least one hub;

controlling the communication of user data on the network by permitting said communication of user data through the at least one hub while the volume of data used by the user is within the data volume allowance for the user, and

preventing said communication of user data if the volume of data used by the user reaches or exceeds the data volume allowance.

14. A method for controlling, at a plurality of points on a network, the communication of user data associated with a user on the network, the method comprising:

in at least one wireless access point on the network,

accessing user profile information of the user, wherein the user profile information comprises at least a data volume allowance for the user;

monitoring a volume of data used by the user over the network regardless of which of a plurality of devices the user uses to access the at least one wireless access point;

controlling the communication of user data at a plurality of points on the network by permitting said communication of user data through the at least one wireless access point while the volume of data used by the user is within a data volume allowance for the user, and

preventing said communication of user data if the volume of data used by the user reaches or exceeds the data volume allowance.

15. A network hub associated with a device providing access to a network, the network hub being configured to access user profile information of a user of the device, wherein the user profile information comprises at least a data volume allowance for the user, to monitor a volume of data used by the user over the network regardless of which of a plurality of devices the user uses to access the network hub, and to control the communication of data associated with the user at a plurality of points on the network, wherein the network hub prevents a user from accessing the network when the volume of data used by the user reaches or exceeds the data value allowance for the user.

16. A wireless access point associated with a device providing access to a network, the wireless access point being configured to access user profile information of a user of the device, wherein the user profile information comprises at least a data volume allowance for the user, to monitor a volume of data used by the user over the network regardless of which of a plurality of devices the user uses to access the wireless access point, and to control the communication of data associated with a user at a plurality of points on the network, wherein the wireless access point prevents a user from accessing the network when the volume of data used by the user reaches or exceeds the data volume allowance.
