Claim 8:
9. A positioning method used in a wireless communication system that communicates with a mobile station having a GNSS receiving function by using a small cell base station whose communicable area is a small cell having an area of a first size and a macro cell base station whose communicable area is a macro cell having an area larger than the small cell, the macro cell base station having a GNSS receiving function that receives radio waves transmitted from GNSS satellites and obtains GNSS data from the radio waves, the positioning method comprising:
a first transmission step of transmitting positioning data that is data obtained from the GNSS data by the macro cell base station and that is used for positioning with GNSS satellites to the small cell base station in a small cell in which the mobile station exists as user plane data that is data used for communication processing in the small cell using user planes;
a second transmitting step of transmitting the positioning data received by the small cell base station from the small cell base station to the mobile station; and
a positioning step of positioning the mobile station using the positioning data received from the small cell base station and the GNSS data obtained from the radio waves received by the mobile station from the GNSS satellites.
