Abstract: PURPOSE: A handover method in a wireless communications system for train control capable of improving service quality of train communications is provided to reduce handover delay time by omitting a procedure of collecting channel information of a target base station candidate group in order to select one target base station. CONSTITUTION: An information storage unit stores base station identifier sequence information before a train departs(S310). By the base station identifier sequence information, a base station identifier installed in a service route of the train is arranged according to the direction of progress of the service route. A handover performing unit selects a next base station to a currently connected serving base station as a target base station using the base station identifier sequence information(S320). The handover performing unit determines handover to the target base station(S330). [Reference numerals] (S310) Downloading base station identifier sequence information; (S320) Selecting a target base station; (S330) Determining handover; (S340) Performing the handover

Abstract: PURPOSE: A multifunctional mobile terminal having a broadband voice encoder function and a DAB(Digital Audio Broadcasting) receiving function is provided to add a broadband voice encoder function, a DAB receiving function, and an MP3 player function to a mobile terminal. CONSTITUTION: A multifunctional mobile terminal comprises the first and second antennas(ANT1.ANT2), a mobile communication RF part(100), a DAB RF part(200), a terminal central processing part(300), a voice codec(400), an MPEG layer II/III decoder(500), a voice band codec(600), an audio DAC(Digital Analog Converter)(700), and an analog signal input/output part(800). The first and second antennas(ANT1.ANT2) transmit and receive mobile communication data and DAB data respectively. The mobile communication RF part(100) and the DAB RF part(200) execute RF signal processing for mobile communication data and DAB data respectively. The terminal central processing part(300) controls the overall operations of the multifunctional mobile terminal. The voice codec(400), if packet data are supplied from the terminal central processing part(300), regenerates a digital voice signal and transfers it to the voice band codec(600). In case that a digital voice signal is provided from the voice band codec(600), the voice codec(400) compresses the digital voice signal and supplies it to the terminal central processing part(300). The MPEG layer II/III decoder(500) regenerates a digital audio signal from the MP2 or MP3 packet data transmitted from the terminal central processing part(300) and outputs it to the audio DAC(700).
