Method for evaluating correlation validity between estimation result and location information in wireless communication system, and apparatus supporting same

A method for evaluating correlation validity between a measured result and location information which is performed by a network entity in a wireless communication system, the method comprising:

• receiving, by the network entity, a measured result at a first point of time from a user equipment;
• receiving, by the network entity, location information at a second point of time from the user equipment;
• obtaining, by the network entity, correlation validity information for determining a correlation and evaluating correlation validity;
• determining, by the network entity, the correlation between the location information and the measured result;
• and
• performing, by the network entity, the correlation validity evaluation for determining whether the location information has a high correlation with the measured result based on the correlation,
• wherein both the measured result and the location information are used for network performance optimization by the network entity when the location information is determined to have a high correlation with the measured result based on the correlation validity evaluation,
• wherein the measured result is used for the network performance optimization by the network entity when the location information is determined to have a low correlation with the measured result based on the correlation validity evaluation,
• wherein the correlation validity information comprises time information at the first point of time, information about a speed of the user equipment at the first point of time, time information at the second point of time and information about a speed of the user equipment at the second point of time,
• wherein the correlation is determined by calculating a distance interval between a location of the user equipment at the first point of time and a location of the user equipment at the second point of time as the correlation, and the distance interval is calculated as Dmp=|Tm−Tp|×vp, and
• wherein Dmp is the distance interval, Tm is the first point of time, Tp is the second point of time, and vp is a speed of the user equipment.
