Document Type and Number:
Japanese Patent JP2002528016
Kind Code:
A
Abstract:
A pre-paid subscriber account system for use with wireless telephone systems is disclosed. The system, which monitors a subscriber's call, deducts the cost of the call from the subscriber's pre-paid account in real-time, warns the subscriber during a call when the account is nearing depletion, and terminates the call when the account is depleted. The system can also prevent the initiation of a new call when the account is depleted. The system and method uses signaling techniques that will allow the metering or billing of the call, along with any authorization or restrictions, to be done remotely from the actual switching of the call. Call events or chargeable events are transmitted to the pre-paid control system while the communications path of the call is held at the switching system awaiting control information.
