Claim 4:
5. The positioning system according to claim 1, wherein the plurality of first base stations each includes:
a small cell base station having a small cell, which is an area of a first size, as a communicable area; and
a first macro cell base station that has a macro cell, which is an area larger than the small cell, as a communicable area and that has a GNSS reception function of receiving radio waves transmitted from GNSS satellites and obtains GNSS data from the radio waves,
the macro cell base station transmits 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 addressed to the mobile station, the user plane data being data used for communication processing in small cells using user planes,
the small cell base station transmits the user plane data including the positioning data received from the macro cell base station to the mobile station,
the mobile station obtains the positioning data from the user plane data from the small cell base station, and performs positioning of the mobile station using the obtained positioning data and the GNSS data obtained from the radio waves received by the mobile station from the GNSS satellites.
