METHOD FOR PROVIDING OPTIMAL-COST CALL ESTABLISHMENT MANAGEMENT IN SMART-TERMINALS, AND COMPUTER-READABLE RE CORDING MEDIUM FOR STORING CALL ESTABLISHMENT MANAGEMENT PROGRAM IN SMART-TERMINALS

摘要

PURPOSE: A call connection management method for optimizing communication fees in a smart terminal is provided to increase business profits of a specific telecommunication company by automatically calculating communication fees according to communication environments. CONSTITUTION: When a free call is available, a call connection management application determines whether a current call connection is an international call(S13,S14). When the current call connection is a domestic call, the application executes a call connection using an infrastructure communication network(S15). When the current call connection is the international call, the application sets a local call access number(S16). When the free call is unavailable, the application sets a toll-free access number(S17).
