Method of data communication between PLC stations belonging to different PLC cells and apparatus therefor

摘要

Disclosed are a method and apparatus for data communication between power line communication stations belonging to different power line communication cells. The method according to the invention comprises the steps of transmitting the station ID of the PLC receiving station to the PLC CB of the PLC cell to which the PLC transmission station belongs, the GID of the PLC cell to which the PLC receiving station belongs and from the PLC cell to which the PLC receiving station belongs. Receiving an encryption key, encrypting data to be transmitted using an encryption key of a PLC cell to which the PLC receiving station belongs, and a station ID of the PLC receiving station, a GID of the PLC cell to which the PLC receiving station belongs, and an encrypted Transferring the data to the PLC CB. By processing the group ID (GID) and encryption key, which are information about the cells, for communication between different cells, the cell bridge (CB) is actively processing without the manual intervention of the administrator. As a result, the user can more conveniently perform communication between cells.
