Systems and methods for preparing communication events, such as telephone calls, for prepaying customers are described. The systems and methods permit, at the beginning of a communication event, the determination of a time limit for the event based on the available balance in a prepayment account associated with the event.

Systems and methods for prerating costs for a communication event

The invention provides systems and methods that operate to provide seamless roaming to a prepaid subscriber in as many markets as possible. To that end, the systems of the invention include a location register (LR) that can determine the type, or class, of serving market with which the roaming subscriber is registering. Once the class of the serving market is identified, the LR can modify a subscriber's profile as a function of this class, and return to the serving market a profile that will allow the serving market to employ the prepaid platform that services the subscriber and thereby provide services to the roaming subscriber. In optional embodiments, the LR may also respond to location requests from the prepaid platform. The location information may be employed by the subscriber to determine a rate structure for a call, and thereby decrement the subscriber's balance as a function of, at least in part, the location of the roaming subscriber.

Display sign support having detachable component parts and slideable

A portable advertising sign is positioned in proximity to a street and includes a message board. A low power transmitter is physically secured to the sign and generates a modulated RF output signal at a predetermined frequency within the broadcast band. An antenna colocated with the sign is coupled to the transmitter and radiates the transmitter output signal. A cassette tape player is positioned in a secure area physically spaced apart from the sign by a substantial distance and includes a colocated power supply for supplying a DC voltage. A cable conveys the audio output signal from the tape player and the DC voltage from the power supply to the transmitter. The sign message board displays the operating frequency of the transmitter to vehicles passing by the sign.
