On the other hand, the terminal device 100 transmits location information related to the current location so that it can be determined whether the terminal device 100 enters the building and is located in the building when the indoor route guidance service is used. In order to transmit to the , the current location is checked, and the current location check may be performed using, for example, a Global Positioning System (GPS).

First, a method for determining the movement between floors using stairs will be described.

When a specific acceleration pattern is identified based on the acceleration information, the determination unit 220 determines that the terminal device 100 is walking and detects building-related information related to the building.

Here, the building-related information includes location information corresponding to stores in the building, parking lot-related information (eg, parking lot map, number of parking lots, parking status indication, etc.) and internal facility information (eg, elevator, escalator, corridor (stairway) map). etc.), which refers to an InDoorMap including at least one of them, and is preferably stored in advance.

Accordingly, the determination unit 220, when determined based on the horizontal movement information of the terminal device 100, the position change of the terminal device 100 is internal facility information (eg, elevator, escalator, corridor (stairway) map, etc.) Determines whether it matches the position of .

That is, the determination unit 220 determines that the terminal device 100 is walking on the stairs when the change in the location of the terminal device 100 occurs at the location where the internal facility is located.

Next, a method of determining the movement between floors using an elevator will be described.

When the specific acceleration pattern is not confirmed based on the acceleration information, the determination unit 220 checks the acceleration change in the first direction z based on the first acceleration change information of the acceleration information.

As such, when the acceleration change in the first direction z is confirmed, the determination unit 220 checks the position change in the horizontal direction based on the horizontal movement information.

At this time, when the acceleration change in the first direction z is confirmed, but the position change in the horizontal direction is not confirmed, since the terminal device 100 is moving vertically in the elevator, the determination unit 220 ) determines that the terminal device 100 has boarded the elevator.

Finally, a method of determining the movement between floors using an escalator will be described.

The determination unit 220, when the specific acceleration pattern is not confirmed based on the acceleration information, checks the position change in the horizontal direction based on the horizontal movement information.

When the position change in the horizontal direction is confirmed as described above, the determination unit 220 checks the vibration change of the terminal device 100 based on the first acceleration change information and the second acceleration change information of the acceleration information.

At this time, if the change in the position in the horizontal direction is confirmed, but the change in vibration of the terminal device 100 is not confirmed, since the terminal device 100 is moving on the escalator, the determination unit 220 determines the terminal device 100 ) is judged to have boarded the escalator.

On the other hand, the process of determining whether to move between floors using elevators and escalators can be determined using the location of internal facility information (e.g., elevator, escalator, corridor (stairway) map, etc.) of building-related information, unlike the above. Of course.

Thereafter, the determination unit 220 notifies the determination unit 230 that the determination of whether the terminal device 100 moves between floors is completed.

The determination unit 230 performs a function of detecting the position of the terminal device 100 in the building by using the sound signal when the sound signal is detected by the terminal device 100 only in case of inter-floor movement.

More specifically, when the terminal device 100 is moving between floors, the determiner 230 checks whether the terminal device 100 executes an application related to a route guidance service.

That is, when the application related to the route guidance service is executed in the terminal device 100 and the indoor route guidance service is being used, the determination unit 230 receives the sound signal detected from the terminal device 100 .

In this case, the sound signal may be an audio frequency band signal including floor-related information in a building, and is output through a speaker located on each floor.

Accordingly, the determination unit 230 may detect a specific floor reached by the terminal device 100 in the building moving between floors based on the floor-related information. Thereafter, the determination unit 230 determines the location of the terminal device 100 in the building as a specific floor.

On the other hand, if it is confirmed that the application related to the route guidance service is not executed in the terminal device 100 , the determination unit 230 generates and transmits an execution request signal to the terminal device 100 so that the application can be executed.

Thereafter, when the application related to the route guidance service is driven in the terminal device 100 and a sound signal is detected, the determination unit 230 uses the sound signal as described above to move between floors and reach a specific location of the terminal device 100 . The process of detecting the floor and determining the location of the terminal device 100 in the building as a specific floor is performed in the same manner.

On the other hand, when a specific floor reached by the terminal device 100 in a building is confirmed by moving between floors using an acoustic signal, the control unit 240 is configured such that the indoor map data indicating the identified specific floor is provided to the terminal device 100 . will take control

As a result, when the application related to the route guidance service is running in the terminal device 100 , the providing unit 240 determines the specific floor reached by the terminal device 100 moving between floors on the indoor map data provided in real time. If it is confirmed that the application related to the route guidance service is not executed in the terminal device 100, after activating the application of the terminal device 100, the terminal device 100 moves between floors and displays a specific floor reached. The displayed indoor map data will be provided.
