Claim 6:
7. A mobile terminal configured to exchange information with another mobile terminal in a predetermined communication range, the mobile terminal comprising:
a positioning device configured to perform positioning using a radio wave;
a communication device having smaller power consumption than the positioning device, and being configured to detect a relative positional relationship with the other mobile terminal using wireless communication;
a battery configured to supply power to at least the positioning device and the communication device, wherein
the mobile terminal is
configured to at least reduce power to be used by the positioning device, when the relative positional relationship between the other mobile terminal is within a predetermined range, the mobile terminal acquires and sets a position of the other mobile terminal to as to a current position, and
when the relative positional relationship with the other mobile terminal is without the predetermined range, the mobile terminal sets the current position based on the position of the other mobile device and a distance from the mobile terminal to the other mobile terminal,
wherein
the other mobile terminal performs positioning of the position the other mobile terminal:
(i) when power consumption of the positioning device of the other mobile terminal is smaller than power consumption of the positioning device of the mobile terminal, or
(ii) when positioning accuracy of the positioning device of the other mobile terminal is higher than positioning accuracy of the positioning device of the mobile terminal.
