FIG. 1 is a conceptual diagram of a passenger management according to an example.

Facilities requiring security such as buildings or factories should control the passengers. A method 100 for tracking the location of a mobile terminal carried by a visitor can be used as a method of automatically managing a visitor. For example, if it is determined that a mobile device determined to be located outside the facility is located inside the facility, the user having the mobile device may be considered to have entered the facility. As another example, if it is determined that the mobile device that is determined to be located inside the facility is located outside the facility, the user having the mobile device may be considered to be out of the facility.

The criteria for determining the inside and outside of a facility may be the gate or wall of the facility. When the position of the mobile device is detected using a signal having a wide coverage, there may be a large error in the position of the detected mobile device. Thus, in order to accurately detect the position of the mobile device, a signal with narrow coverage can be used rather than a signal with wide coverage. For example, a beacon signal may be used to accurately detect the location of the mobile device.

The mobile device detects the beacon signal using a short range wireless communication function on the mobile device. For example, the short-range wireless communication function may be Bluetooth. The beacon signal can not be detected when the local wireless communication function of the mobile device is inactivated. If the predetermined condition is satisfied, the mobile device can detect the beacon signal if the short range communication function of the mobile device is automatically activated. A method for detecting a change in position of a mobile device based on a detected signal is described in detail below with reference to Figs. 2 to 8, wherein the local communication function of the mobile device is activated.
