Abstract
According to a method of controlling access to a prepaid packet data communication service, a prepaid server transmits a resource response in response to receipt of a resource request for prepaid resources from a prepaid client. The resource response specifies a quota of prepaid resources no greater than a prepaid account balance of a prepaid service subscriber and a resource usage threshold at which the prepaid client provides notification. The prepaid client then receives a notification from the prepaid client indicating that the threshold of prepaid resources has been reached, and in response to the notification, performs an accounting updating reflecting a portion of the prepaid account balance that has been consumed.
