GSM SIM RECEIVING CDMA TERMINAL SETTING ADDITIONAL SERVICE BY MENU SYSTEM AND SETTING METHOD THEREOF, ROAMING SERVICE SYSTEM SUPPLYING SERVICE

摘要

PURPOSE: A GSM(Global System for Mobile communication) SIM(Subscriber Identity Module) CDMA terminal setting an additional service by a menu system is provided to perform an additional service-related setup with the menu system, and to make a GSM feature code correspond to the set additional service, thereby using the additional service in the CDMA terminal. CONSTITUTION: A GSM additional service information storage(1500) stores a feature code. A controller(1540) extracts the feature code corresponding to an additional service setup, transmits the feature code to a GSM system, requests an additional service setup of the GSM system, and displays a response result for the additional service setup request. A wireless transceiver(1530) performs wireless communication with a CDMA system. A display(1560) outputs characters or videos to a user. A keypad(1570) receives a key input signal from the user, and transmits the signal to the controller(1540). A data storage(1550) stores data necessary for controlling a CDMA terminal.
