APPARATUS AND METHOD FOR CALCULATING LOCATION OF MOBILE STATION IN WIRELESS NETWORK
First Claim
1. A method for measuring a position of a user equipment (UE) located in an indoor by a network node, the method comprising:
- receiving, from the UE, measurement information including a intensity of a signal received from an access point (AP) and feedback information including information about a sensor configured to measure movement of the UE and sensor measurement information regarding movement of the UE, measured by the sensor;
estimating the position of the UE based on the measurement information and information on a predetermined reference point corresponding to the intensity of the signal; and
calculating an indoor position of the UE by applying the information about the sensor and a sensor correction factor corresponding to the sensor measurement information to the estimated position of the UE.

Abstract
A method for measuring the indoor position of a UE by a network node according to an embodiment of the present invention may include: receiving, from the UE, measurement information including the intensity of a signal received from an access point (AP) and feedback information including information about a sensor configured to measure movement of the UE and sensor measurement information regarding movement of the UE, measured by the sensor; estimating the position of the UE based on the measurement information and received signal strength (RSS) from the AP, predetermined for each reference point; and calculating the indoor position of the UE by applying the information about the sensor and a sensor correction factor corresponding to the sensor measurement information to the estimated position of the UE.
