Abstract

The present invention relates to a method for setting a home code in a network system and a device for a network system. The method and device allow a user to conveniently remote control the operation of and monitor the operational state of appliances. Thanks to the method and device, a user, for example, who is locating at home or out-of-home, can control the operation or monitor the operational state of various appliances such as refrigerator or laundry machine through a living network installed at home, such as RS-485 network, a low power RF network, or a power line network. The method of setting a home code in a network system includes a first step of producing a random home code value using a random numbers generation algorithm, a second step of checking whether the random home code value is a unique code, and a third step of setting the random home code value as a home code of all devices connected to a network when it is found that the random home code value is a unique code as the result of checking, so that all the devices connected to the same network have the same home code. The present invention is very useful in ability of effectively setting and managing a unique home code in a network.

Claims

1. A method of setting a home code in a network system, comprising:

a first step of checking whether a network is an initially configured network;

a second step of creating a random home code value when it is determined that the network is an initially configured network as the result of the checking;

a third step of checking whether the created random home code value is used in other networks connected to the network; and

a fourth step of setting the created random home code value as a unique home code for the network when it is determined that the created random home code value is not used in other networks as the result of the checking.

2. The method according to claim 1, wherein checking whether the network is an initially configured network is performed by checking a home code in a network manager or a network profile.

3. The method according to claim 1, wherein the step of producing a random home code value can be omitted when it is determined that the network is not an initially configured network.

4. The method according to claim 1, wherein the step of creating a random home code value is carried out in a home code control sublayer which received production request from a network manager.

5. The method according to claim 1, further comprising a step of deleting the generated random home code value and then creating another random home code value when it is found that the generated random home code is used in other networks.

6. The method according to claim 1, wherein, in the fourth step, the home code value is set to all devices connected to the same network as a unique home code by a home code control sublayer which received setting request from a network manager.

7. A device for a network system having a home code requested by a network manger of the network system and produced by a home code controller.
