ABSTRACT:
There is provided a positioning system which generates an appropriate response according to a positioning accuracy request class from a client device. A client device101specifies the positioning accuracy and the request class thereof that it requests to transmit a positioning request of a mobile station103to a server device102. The server device102checks the positioning accuracy requested by the client device101, and, if positioning results which satisfy the requested accuracy exist, responds the positioning results. If the positioning results which satisfy the requested accuracy do not exist, the server device102checks the accuracy request class, selects the positioning results with the highest positioning accuracy to respond to the client device101in the case of a second class (“Best Effort”), and notifies an error to the client device101in the case of a first class (“Assured”).
