摘要

PURPOSE: A mobile communication system capable of automatically selecting the lowest price is provided to enable a user to select whether to use a lowest price selecting function whenever the user uses an international call service, and to operate the function only when the user selects to use the function. CONSTITUTION: A user dials a telephone number(100). A system recognizes a service subscriber in reference to a subscriber profile(110). The system decides whether an international call service ID number is included in the dialed telephone number(120). If so, the system refers to an international call service charge data table(130). The system replaces the international call service ID number with a searched lowest price service ID number(140). The system connects an international call with a newly formed telephone number(150).
