Abstract

The present invention relates to a machine to machine communication (M2M) technique, and to a technique for changing an update period of location information in an M2M system. In particular, the present invention relates to a method and a device for allowing a common service entity to dynamically set an update period of location information in an M2M system.

Claims

1. A method of acquiring location information by a common service entity, the method comprising:

generating location policy resources according to a request of an originator;

making a request for location information of a device to a network service entity according to location update period information included in the location policy resources; and

changing the location update period information based on at least one piece of the location information received from the network service entity and state information of the device.

2. The method of claim 1, wherein the changing of the location update period information comprises, when there is no request of the originator, independently changing the location update period information based on at least one piece of the location information and the state information of the device.

3. The method of claim 1, wherein the location update period information includes list information including one or more location update period values.

4. The method of claim 3, wherein the making of the request for location information of the device comprises making the request for the location information of the device to the network service entity based on a first location update period value of the list information.

5. The method of claim 1, wherein the location update period information includes period set attribute information including one or more location update period sets that have been classified and configured according to each type of state information of the device.

6. The method of claim 5, wherein each of the location update period sets corresponds to list information including one or more location update period values configured according to the state information of the device.

7. The method of claim 5, wherein the location update period information includes period element attribute information including a location update period value applied to the making of the request for the location information of the device to the network service entity.

8. The method of claim 1, wherein the location policy information is changed according to a request for updating the location policy information from the originator.

9. The method of claim 1, wherein the state information of the device includes at least one piece of power information, speed information, absolute location information, relative location information of a previous location, time information, and application driving information.

10. A method of providing location information by a network service entity, the method comprising:

receiving a request for location information of a device from a common service entity based on a period determined according to location update period information; and

transferring the location information of the device to the common service entity,

wherein the location update period information is dynamically changed by the common service entity based on at least one piece of the location information of the device and state information of the device.

11. The method of claim 10, wherein the location update period information includes list information including one or more location update period values.

12. The method of claim 10, wherein the location update period information includes period set attribute information including one or more location update period sets that have been classified and configured according to each type of state information of the device.

13. The method of claim 12, wherein each of the location update period sets corresponds to list information including one or more location update period values configured according to the state information of the device.

14. A common service entity for acquiring location information, the common service entity comprising:

a controller configured to generate location policy resources according to a request of an originator; and

a transmitter configured to make a request for location information of a device to a network service entity according to location update period information included in the location policy resources,

wherein the controller changes the location update period information based on at least one piece of the location information received from the network service entity and state information of the device.

15. The common service entity of claim 14, wherein, when there is no request of the originator, the controller independently changes the location update period information based on at least one piece of the location information and the state information of the device.

16. The common service entity of claim 14, wherein the location update period information includes list information including one or more location update periods.

17. The common service entity of claim 16, wherein the transmitter makes a request for the location information of the device to the network service entity based on a first location update period value of the list information.

18. The common service entity of claim 14, wherein the location update period information includes period set attribute information including one or more location update period sets that have been classified and configured according to each type of state information of the device.

19. The common service entity of claim 18, wherein each of the location update period sets corresponds to list information including one or more location update period values configured according to the state information of the device.

20. The common service entity of claim 18, wherein the location update period information includes period element attribute information including a location update period value applied to the making of the request for the location information of the device to the network service entity.
