To provide a terminal location estimation method capable of accurately estimating
a location of a mobile terminal when providing information services according to
the location of the terminal in a radio communication system. A positioning server
sends a location measurement probe message to the mobile terminal in order to measure
the location of the terminal. Each of base stations receives a response message
broadcasted from the terminal, measures the reception level and delay spread and
sends the measurement results to the positioning server. The positioning server
has a radio wave propagation estimating portion and a database for storing estimation
results thereof. The server estimates the location of the terminal by checking
the measurement results of the base stations against the estimation results on
radio wave propagation stored in the database.
