MOBILE COMMUNICATION SYSTEM FOR PROVIDING A TELEMATICS SERVICE USING AN UNSTRUCTURED SUPPLEMENTARY SERVICE DATA PROTOCOL, A TERMINAL DEVICE AND A METHOD THEREOF, CAPABLE OF TRANSMITTING DATA WITH LARGER CAPACITY

摘要

PURPOSE: A mobile communication system for providing a telematics service using an unstructured supplementary service data protocol, a terminal device and a method thereof are provided to supply a data transceiving path between a terminal device mounted on a car and a telematics service provider using an unstructured supplementary service data protocol.;CONSTITUTION: An exchange(240) performs unstructured supplementary service data protocol communication to receive car information. A relay device(280) performs the unstructured supplementary service data protocol communication with a home location register(260). The relay device transfers a service processed result to the terminal device through the home location register and the exchange.;COPYRIGHT KIPO 2010
