MOBILE TERMINAL CAPABLE OF LOCALIZATION, LOCALIZATION SERVER AND METHOD FOR LOCALIZING THE MOBILE TERMINAL USING THE LOCALIZATION SERVER

摘要

A mobile terminal capable of localization, a localization server, and a method for localizing the mobile terminal using the localization server are disclosed. The disclosed localization server includes a control unit configured to control transmissions of visible-light signals from a multiple number of visible-light transmitting devices; and a position computing unit configured to compute a position of a mobile terminal based on time information regarding when the visible-light signals transmitted respectively from the plurality of visible-light transmitting devices were received at the mobile terminal, where the control unit controls the transmissions such that each of the plurality of visible-light transmitting devices sequentially transmits the visible-light signal for a particular first time period with no overlapping of transmission times of the visible-light signals transmitted respectively from the plurality of visible-light transmitting devices.

1. A mobile terminal capable of localization, the mobile terminal comprising:
a receiver unit configured to receive visible-light signals, the visible-light signals sequentially transmitted from a plurality of visible-light transceiver devices for a particular first time period such that there is no overlapping of transmission times; a time measuring unit configured to generate receiving time information regarding times at which the sequentially transmitted visible-light signals are received information; and a position computing unit configured to compute a position of the mobile terminal by using the receiving time information of the sequentially transmitted visible-light signals.
