Position estimation of a wireless terminal in a structure using base station signal information

A method for transmitting information, the method comprising:

• receiving, by circuitry of a wireless terminal, a wireless signal transmitted from a base station, the wireless signal including base station identification information;
• receiving, by the circuitry, internal location information for a building, the internal location information indicating a location within the building;
• accessing, by the circuitry, signal intensity information of the wireless signal received from the base station in response to acceptance of a predetermined user input operation after receiving the internal location information for the building;
• and
• transmitting, by the circuitry, the signal intensity information, the base station identification information, and the internal location information, wherein
• the signal intensity information is associated with the base station identification information and the internal location information in connection with a request for an estimated position for the location within the building, and
• the signal intensity information is transmitted after the acceptance of the predetermined user input operation.
