Abstract

Disclosed is a method for generating a house code (HC) in a home network based on a living network control protocol (LnCP), in which a (HC) having a small capacity is generated by using a region separation code and a household separation code and the generated HC is provided to each household. To this end, in the home network generating a HC for dividing each household and providing the generated HC to each household, the method comprises the steps of: generating a portion of the HC as region separation codes for dividing into plural regions; and generating another portion of the HC as household separation codes for providing to each household of the plural regions.

Claims

1. A method for generating a house code (HC) in a home network comprising the steps of:

generating one portion of the HC as region separation codes for separating plural regions; and

generating another portion of the HC as household separation codes for providing to each household of the plural regions.

2. The method of claim 1, further comprising a step of providing the generated region separation codes to the plural regions.

3. The method of claim 1, further comprising a step of providing the generated household separation codes to plural households.

4. The method of claim 1, wherein the step of generating the region separation codes further comprises a step of providing adjacent regions among the divided regions with different region separation codes.

5. The method of claim 1, wherein the household separation codes are used as unique codes for each household in the divided regions.

6. The method of claim 1, wherein a capacity of the HC is 2 bytes, the one portion has 3 bits, and the another portion has 13 bits.

7. The method of claim 2, wherein the step of generating the region separation code includes the steps of:

dividing regions to which the HC will be provided;

setting a basic region among the divided plural regions and providing a region separation code of the HC to the basic region;

determining an order of the divided regions to which the region separation code of the HC will be provided on the basis of the set basic region; and

selecting the divided regions one by one by the determined order and providing a region adjacent to the selected region with a region separation code not consistent with already provided region separation codes.

8. The method of claim 7, wherein the step of generating the household separation code includes a step of providing a household separation code of the HC not consistent with already provided codes to each household in the plural divided regions when the one region separation code is provided.

9. The method of claim 2, wherein the step of providing the region separation code of the HC includes the steps of:

setting regions adjacent one another among the plural regions as basic regions; and

providing the basic regions with the region separation codes without overlapping with one another.

10. The method of claim 7, wherein the step of providing a region separation code not consistent with already provided region separation codes includes the steps of:

operating region separation codes of the plural divided regions having the region separation codes among the divided regions adjacent to the selected one divided region by an exclusive OR; and

then

providing a value obtained from the exclusive OR to a region adjacent to the selected region as a region separation code.

11. The method of claim 10, further comprising the steps of:

determining whether the value obtained by the exclusive OR is consistent with region separation codes already provided to adjacent divided regions or not; and

providing a new value not consistent with already provided region separation codes to the adjacent divided regions by operating the first said value with sequentially preset values consecutively by the exclusive OR in case that the value obtained by the exclusive OR is consistent with region separation codes already provided to adjacent divided regions.

12. A method for generating a house code (HC) in a home network comprising the steps of:

dividing regions to which the HC will be provided;

setting a basic region among the divided plural regions and providing a region separation code of the HC to the basic region;

determining an order of divided regions to which the region separation code of the HC will be provided on the basis of the set basic region;

selecting the divided regions one by one by the determined order and providing one region separation code not consistent with already provided region separation codes to a region adjacent to the selected region; and

providing a household separation code of the HC not consistent with already provided codes to each household in the plural divided regions, when the region separation code is provided.

13. The method of claim 12, wherein the step of providing the region separation code of the HC includes the steps of:

setting regions adjacent one another among the plural regions as basic regions; and

providing the basic regions with the region separation codes without overlapping with one another.

14. The method of claim 12, wherein the step of providing one region separation code not consistent with already provided region separation codes includes the steps of:

operating region separation codes of the plural divided regions having the region separation codes among the divided regions adjacent to the selected one divided region by an exclusive OR; and

then

providing a value obtained from the exclusive OR to a region adjacent to the selected region as a region separation code.

15. The method of claim 14, further comprising the steps of:

determining whether the value obtained by the exclusive OR is consistent with region separation codes already provided to adjacent divided regions or not; and

providing a new value not consistent with already provided region separation codes to the adjacent divided regions by operating the first said value with sequentially preset values consecutively by the exclusive OR in case that the value obtained by the exclusive OR is consistent with region separation codes already provided to adjacent divided regions.
