MOBILE TERMINAL AND METHOD

摘要

One aspect of the present invention relates to a mobile terminal having a positioning function, comprising: a GPS positioning unit configured to perform GPS based positioning to obtain a positioning result including a position of the mobile terminal and a measurement status regarding the GPS based positioning; a base station based positioning unit configured to perform base station based positioning to obtain a positioning result including a position of the mobile terminal and a measurement status regarding the base station based positioning; a historical positional information storage unit configured to store historical positional information including the positioning results obtained by the GPS based positioning unit and the base station based positioning unit; and a positioning determination unit configured to determine whether a valid positioning result regarding a camped base station of the mobile terminal is in the historical positional information, wherein when positioning is performed for the mobile terminal in response to activation of the positioning function, prior to activation of the GPS based positioning and the base station based positioning, the positioning determination unit identifies the camped base station of the mobile terminal, identifies positioning results regarding the identified base station in the historical positional information, detects a valid positioning result from the identified positioning results based on the measurement status of the identified positioning results and provides the detected positioning result as the positioning result for the mobile terminal.
