Abstract

The present invention discloses a home network system (1) using a living network control protocol. The home network system (1) includes: at least one electric device; (40-49); a network manager (20-23) for controlling and monitoring the electric device (40-49); and a network based on a predetermined protocol, for connecting the electric device (40-49) and the network managers (20-23), wherein the network manager (20-23) stores a HomNet Profile containing information on the electric device (40-49), and updates the HomNet Profile by communicating with the electric device (40-49) through the network, wherein the HomNet Profile comprises at least one of a device information file containing specific intrinsic information on the electric device, a node parameter file containing a node parameter designated for the electric device, a device operation file containing data on an operational state of the electric device and a scenario file for defining supplementary services for the electric device.

Claims

1. An electric device,

capable of communicating with other electric device through a network,

wherein the electric device stores a HomNet Profile containing information on the other electric device, and updates the HomNet Profile by communicating with the other electric device through the network,

wherein the HomNet Profile comprises at least one of a device information file containing specific intrinsic information on the other electric device, a node parameter file containing a node parameter designated for the other electric device, a device operation file containing data on an operational state of the other electric device and a scenario file for defining supplementary services for the other electric device.

2. The device of claim 1, wherein the device information file comprises at least one of a name of the other electric device, a name of device maker, a name of device model, a software version, a type of the device, a product code and implemented service code.

3. The device of claim 2, wherein the type of the device comprises one of a slave device, a master device, a network manager and a hybrid device.

4. The device of claim 1, wherein the node parameter file comprises at least one of a product code, a logical address, a cluster code, an option value, a communication buffer size, an alive interval and a set-up time.

5. The device of claim 1, wherein the device operation file comprises at least one of a device state, a detail status information, a waiting time for a response packet, and an installation location code.

6. The device of claim 5, wherein the device state is either an online or offline state.

7. The device of claim 5 or claim 6, wherein the detail status information is a status information when the electric device is online.

8. The device of claim 7, wherein the detail status information is one of Standby, Operating, Pause and Error.

9. The device of claim 1, wherein the scenario file comprises at least one of an event program type, an event program data, a reservation service code, a reservation time and a reservation data.

10. The device of claim 9, wherein the event program type indicates a storage for the event program.

11. The device of claim 9, wherein the reservation type comprises a one-time reservation or a persistent reservation.

12. The device of claim 1, further comprises second electric device, and performs a synchronization process on the HomNet Profile by transmitting/receiving changes in the HomNet Profile between the electric device and the second electric device.
