Abstract

When a person of holding a mobile station gets near to a previously set target position, application 200 is started and service of utilizing positional information is provided to the person of holding the mobile station or a third party. The mobile station includes a position comparator 103 for comparing a current position of the mobile station calculated by a position calculator 102 by using a signal from an antenna 100 with a target position inputted from means for target position input 104 and an application controller 106 for controlling the application 200 by using a result of position comparison 120. Further, a frequency of position calculation is pertinently controlled in the position calculator 102 by a position calculation controller 107 operated by the result of position comparison 120.
