Base station and mobile terminal for location detection, and location detecting method
First Claim
1. A mobile terminal for location detection, comprising:
- a GPS receiver for detecting a location of a base station using a GPS;
a DSRC transceiver for extracting location information from a beacon signal transmitted from the base station in an area where location detection is impossible through the GPS receiver to detect the location of the base station; and
a central processing unit for extracting location detection data through the GPS receiver or the DSRC transceiver and displaying it on a map.

Abstract
Disclosed are a base station and a mobile terminal for location detection, and a location detecting method. The base station in which a plurality of antennas having RF modules are installed transmits a signal including location information of each of the antennas to the mobile terminal. The mobile terminal carries out location detection by selectively using location information received from a GPS receiver or location information received from a DSRC transceiver. The base station and mobile terminal for location detection can perform location detection with high accuracy using the existing DSRC service. Thus, the base station and mobile terminal can carry out location detection having an error of approximately 10 m in downtown areas or buildings.

2. A location detecting method comprising:
-
a) detecting a beacon signal including location information, transmitted from a base station, through a DSRC module installed in a mobile terminal;
b) when the beacon signal is detected, extracting the location information from the beacon signal to use it as location detection data; and
c) when the beacon signal is not detected, using location detection data detected using a GPS.
