SYSTEM AND METHOD FOR FINDING HIGH ACCURACY POSITION OF MOBILE DEVICE BASED ON SECURE DIGITAL-CARD, UNIVERSAL SUBSCRIBER IDENTITY AND ULTRA-WIDEBAND

摘要

The present invention relates to a system for measuring an indoor location with high accuracy based on convergence of an SD-CARD, a USIM, and a UWB and a method thereof which are used in an indoor location service. A system for measuring an indoor location with high accuracy based on convergence of an SD-CARD, a USIM, and a UWB according to a first aspect of the present invention comprises: a mobile terminal (10) for transceiving data by being coupled with at least one of a UB-SIM (20a) and a UB-CARD (20b) by an interface; and a location measuring server (30) for receiving GPS location information of the mobile terminal (10) through a communication network (50), and transmitting indoor map data to the mobile terminal through the communication network (50) when the mobile terminal is located in a service region building area by using the GPS location information.
