Abstract

A user terminal finds an outdoor path up to an outdoor access point of a building in which a destination is located, using an outdoor map. The user terminal receives an indoor map of the building to find an indoor path up to the destination from an indoor access point of the building using the indoor map. The user terminal reflects the indoor path to the outdoor path to create an outdoor and indoor linked path.

Claims

1. A method for finding a destination in a user terminal, the method comprising:

finding an outdoor path up to an outdoor access point of a building in which the destination is located, using an outdoor map;

receiving an indoor map of the building;

finding an indoor path up to the destination from an indoor access point of the building using the indoor map; and

reflecting the indoor path to the outdoor path to create an outdoor and indoor linked path.

2. The method of claim 1, wherein the outdoor map includes one or more outdoor access points to the building, and the indoor map includes one or more indoor access points to the building.

3. The method of claim 2, wherein the indoor map and the outdoor map are separately stored in different storage spaces, respectively.

4. The method of claim 3, wherein the indoor map and the outdoor map have a delete period and a delete process that are set different each other.

5. A user terminal, comprising:

a first storage storing an outdoor map;

a path finding unit configured to find an outdoor path using the outdoor map up to an outdoor access point of a building when the destination is located at an indoor location within the building, find an indoor path up to the destination from an indoor access point of the building using an indoor map, and reflect the indoor path to the outdoor path to create an outdoor and indoor linked path;

a communication unit configured to receive the indoor map of the building; and

a path providing unit configured to provide the outdoor and indoor linked path to a user.

6. The user terminal of claim 5, further comprising an input unit configured to input the destination;

and a second storage for storing the indoor map.

7. The user terminal of claim 6, wherein the outdoor map includes one or more outdoor access points to the building and the indoor map includes one or more one or more indoor access points to the building.

8. A method for finding a destination of an indoor location in a user terminal having an outdoor map, the method comprising:

determining whether or not an indoor map of a building at which the destination is located is stored;

finding a path up to the destination using the outdoor map and the indoor map when the indoor map is stored;

finding an outdoor path up to an outdoor access point of the building using the outdoor map when the indoor map is not stored;

providing the outdoor path; and

requesting the indoor map of the building.

9. The method of claim 8, further comprising:

receiving the indoor map;

finding an indoor path up to the destination from an indoor access point using the indoor map; and

reflecting the indoor path to the outdoor path to create an outdoor and indoor linked path.

10. The method of claim 9, wherein the user terminal is a fixed user terminal, the method further comprising:

relaying the indoor path to another portable user terminal when a user enter an inner place at which the destination of the inner location is located.
