Abstract
Accordingly, the present invention provides a toolkit for building programmable rules of operation for a prepaid mobile communications unit and for loading the rules into the prepaid mobile unit's internal memory. A rules development language is provided with a predetermined syntax. A rule set is composed of sentences comprising strings of sequential operands terminated by a delimiter operand. Each operand comprises a low-level operator and its corresponding argument. The function of each low-level operator is predefined, with the number of corresponding arguments varying according to the operator type. Once constructed, the rules are compressed and loaded into the internal memory of a prepaid mobile unit and used to determine call restrictions, click rates, surcharges, or otherwise process calls. The compressed rules are encoded into number segments which are delivered to the internal memory of the prepaid mobile unit using a transport mechanism such as, for example, the mobile unit's keypad, or using an over-the-air transport protocol. Inside the communication device mobile communications unit, the compressed rules are then reassembled from the received number segments and stored…
