Claim Text:
1. 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 D wherein D
