Abstract

A method of controlling provision of services from a network element to a subscriber comprising: defining a credit threshold representing the amount of credit remaining to the subscriber below which services will no longer be provided to that subscriber; responsive to a request for a first service from the subscriber, defining a quota of service units and, in the event that the credit remaining to the subscriber after funding said quota falls below the credit threshold, returning a service control indication with said quota; responsive to a subsequent request for a second service from the subscriber, returning a defined quota of service units with said service control indication; and monitoring usage of said service units in providing the first or second service and when it is determined that the quota has been used up, acting on the service control indication to interrupt said service provision.

Claims

1. A method of controlling provision of services from a network element to a subscriber, the method comprising:

defining a credit threshold representing an amount of credit remaining to the subscriber below which services will no longer be provided to that subscriber;

responsive to a request for a first service from the subscriber, defining a quota of service units and, in the event that credit remaining to the subscriber after funding said quota falls below the credit threshold, returning a service control indication with said quota;

responsive to a subsequent request for a second service from the subscriber, returning the defined quota of service units with said service control indication; and

monitoring usage of said service units in providing the first service or the second service and when it is determined that the quota has been used up, acting on the service control indication to interrupt a service provision.

2. The method according to claim 1, wherein said method is used to control provisions of services from the network element to the subscriber in a wireless network.

3. The method according to claim 1, wherein the request for the first service is transmitted from the subscriber as a credit control request message in accordance with a predetermined protocol.

4. The method according to claim 3, wherein the service control indication and said quota are returned to the subscriber in the form of a credit control answer message in accordance with said predetermined protocol.

5. The method according to claim 3, wherein said predetermined protocol is a diameter protocol.

6. The method according to claim 1, wherein said quota is defined as a value in an attribute value pair.

7. The method according to claim 1, wherein said service control indication is associated with an action value defining one of a plurality of actions to be implemented when it is determined that the quota has been used up.

8. The method according to claim 7, wherein said actions are selected from the group comprising terminate service, redirect service, and restrict access to service.

9. The method according to claim 1, wherein said quota is defined in terms of data volume.

10. The method according to claim 1, wherein said quota is defined in terms of time.

11. The method according to claim 1, wherein a low credit indication is provided with the service control indication when the credit falls below the credit threshold.

12. The method according to claim 11, wherein when a new quota is requested for either the first service or the second service, said service provision is terminated if the low credit indication has been provided, until it has been established that there is sufficient credit to fund the new quota.

13. An online charging system controlling the provision of services between a network element and a subscriber in a communications network, the online charging system comprising:

means for defining a credit threshold representing an amount of credit remaining to the subscriber below which services will no longer be provided to that subscriber;

means, responsive to a request for a first service from the subscriber, for defining a quota of service units and, in the event that credit remaining to the subscriber after funding said quota falls below the credit threshold, for returning a service control indication with said quota, said means being responsive to a subsequent request for a second service from the subscriber for returning the defined quota of service units with said service control indication.

14. The online charging system according to claim 13, comprising a diameter credit control server.

15. The online charging system according to claim 13, which comprises means for providing a low credit indication with the service control indication when the credit falls below the credit threshold.

16. A communications network including an online charging system according to claim 13 and a network element, the communications network comprising:

means for monitoring usage of said service units and providing the first service or the second service and when it is determined that the quota has been used up, said means being operable to act on the service control indication to interrupt a service provision.

17. The communications network according to claim 16, wherein the communications network is implemented as a wireless communications network.

18. The communications network according to claim 16, wherein said monitoring means is implemented in a diameter credit control application client.

19. The communications network according to claim 18, wherein the network element is selected from a group comprising a network access server, session initiation protocol proxy, messaging service, content service, and gaming server.

20. The communications network according to claim 16, wherein the network element comprises means for terminating service when a new quota is requested if a low credit indication has been provided, until it has been established that there is sufficient credit to fund the new quota.

21. A computer program product embodied on a computer readable medium, the computer program product comprising program code means which, when loaded into a computer, carries out the steps of:

responsive to a request for a first service from a subscriber in a network, defining a quota of service units and, in the event that credit remaining to the subscriber after funding said quota falls below a credit threshold, returning a service control indication with said quota; and

responsive to a subsequent request for a second service from the subscriber, returning the defined quota of service units with said service control indication.

22. A computer program product embodied on a computer readable medium, the computer program product comprising program code means which, when loaded into a computer, causes a computer to carry out a method comprising:

monitoring usage of service units in providing at least one of a first service and a second service, and when it is determined that a defined quota of service units has been used up, acting on a service control indication to interrupt a service provision.
