When a result of this judgment is affirmative, the terminal10A transmits an assistance information request to a position measuring assistance server50.When the assistance information is returned from the position measuring assistance server50in response to this the assistance information request, in the cellular phone10A, the assistance information is received and stored, and then prepared for a command for position measuring by the user, for which possibility of being made is higher in a short period. As a result, it is possible to perform quickly the position measuring of a current location of the mobile communication terminal.
