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 a region separation code for dividing plural regions; and generating another portion of the HC as a household separation code for separating households in each of the plural regions.

Claims

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

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

generating another portion of the HC as a household separation code for identifying each household of the plural regions, wherein the step of generating the region separation code includes the steps of;

dividing regions to which HCs will be provided;

setting a basic region from the divided regions and providing at least one region separation code of the HCs to the basic region;

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

selecting the other 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, and

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 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.

2. The method of claim 1, further comprising the steps of:

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

providing a new value not consistent with the region separation codes already provided to the adjacent divided regions.

3. The method of claim 2, wherein the step of providing the new values includes:

operating the value obtained by the exclusive OR with sequentially preset values consecutively by the exclusive OR in case that the determining step determines that the values obtained by the exclusive OR is consistent with the region separation codes already provided to the adjacent divided regions.

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

dividing regions to which HCs will be provided;

setting a basic region among the divided regions and providing at least one region separation code of the HCs to the basic region;

determining an order of other divided regions to which the region separation codes of the HCs will be provided on the basis of the set basic region;

selecting the other divided regions one by one by the determined order and providing one region separation code of the HC 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 household separation codes to each household in the divided regions when the region separation codes are provided, the household separation code identifying a household,

wherein some regions not adjacent to each other have a same separation code so a number of separation codes used to separate the divided regions is less than a number of the divided regions.

5. The method of claim 4, wherein the step of providing the region separation code of the HC includes the steps of:

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

providing the basic regions with the region separation codes with the adjacent basic regions having different region separation codes.

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

dividing regions to which HCs will be provided;

setting a basic region among the divided regions and providing at least one region separation code of the HCs to the basic region;

determining an order of other divided regions to which the region separation codes of the HCs will be provided on the basis of the set basic region;

selecting the other divided regions one by one by the determined order and providing one region separation code of the HC 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 household separation codes to each household in the divided regions when the region separation codes are provided, the household separation code identifying a household, wherein the step of providing the region separation code includes the steps of;

operating region separation codes of the 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.

7. The method of claim 6, further comprising the steps of:

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

providing a new value not consistent with the region separation codes already provided to the adjacent divided regions.
