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.
