Indoor/outdoor decision apparatus and indoor/outdoor decision method
First Claim
1. An indoor/outdoor decision apparatus for making an indoor/outdoor decision on whether a mobile communication terminal is located indoors or outdoors, comprising:
- a communication information acquiring unit which acquires communication information about wireless communication at the mobile communication terminal, the communication information including at least a value associated with a reception intensity of a radio wave received by the mobile communication terminal from at least one radio wave transmitter;
an environment information acquiring unit which acquires environment information indicative of an environment associated with the mobile communication terminal from the mobile communication terminal, the environment information including at least time information, weather information, and region information associated with the mobile communication terminal;
a criterion setting unit which sets a threshold as a criterion for the indoor/outdoor decision, according to the environment information acquired by the environment information acquiring unit; and
a deciding unit which makes the indoor/outdoor decision by comparing the value associated with the reception intensity acquired by the communication information acquiring unit, with the threshold set by the criterion setting unit.
