ABSTRACT:
A prepaid service platform monitors a prepaid balance for a mobile station that operates in accordance with a prepaid wireless service plan. When the prepaid balance reaches a predetermined value, such as zero, the prepaid service platform signals to the mobile station's home location register (HLR). In response, the HLR changes at least one call authorization in an HLR profile for the mobile station and also signals to the serving system currently serving the mobile station. The serving system responsively changes at least one call authorization in a serving-system profile for the mobile station. As a result of these changes to the mobile station's call authorizations, the mobile station may be prevented from making and/or receiving chargeable calls.
