Home network system

An electronic device includes an interface unit; a processor configured to communicate with one other electronic device; where a message communicated between the electronic device and the other electronic device includes a message type field and a transmission counter field. The message type field indicates a type of the message. The transmission counter field indicates how many times the same message is transmitted, and a range of a value included in the transmission counter field is determined based on the type of the message indicated by the message type field. The interface unit receives a device information message from the other electronic device, and generates a profile for managing the other electronic device based on the device information message. The profile comprises at least one of a device information file containing specific information on the other electronic device, a node parameter file containing a node parameter designated for the other electronic device, a device operation file containing data on an operational state of the other electronic device, and a scenario file for defining supplementary services for the other electronic device.
