First Claim
Patent Images
1. A mobile radio terminal comprising:
- a communication unit configured to establish radio communication with a base station;
a memory unit configured to store an application;
a control unit configured to;
execute the application stored in the memory unit;
receive, from the application, a request to obtain the current position of the mobile radio terminal;
determine, when the mobile radio terminal is in radio communication with a base station of a contract carrier, that the mobile radio terminal is not roaming or, when the communication unit is in radio communication with a base station of a roaming carrier, that the mobile radio terminal is roaming;
obtain the current position of the mobile radio terminal, and provide the current position of the mobile radio terminal to the application, if the mobile radio terminal is not roaming; and
notify the application that that the current position of the mobile radio terminal cannot be obtained if the mobile radio terminal is roaming.

Abstract
When active software makes a request for measuring position information, during roaming, a control unit does not execute GPS measurement, but notifies the software of an error indicating that, for example, measurement is failed, and thereby prevents establishment of communication for a function which cannot be executed by the software.
