ABSTRACT:
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.
