METHOD OF DISTRIBUTING GROUP IDS IN PLC NETWORK, METHOD OF RECEIVING GROUP IDS IN PLC NETWORK, AUTHENTICATION APPARATUS AND PLC APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a method of distributing group identifiers IDs (GIDs) in a power line communication (PLC) network, a method of receiving the GIDs, an authentication apparatus and a PLC apparatus.;SOLUTION: The authentication apparatus includes: an authentication mode storage section which stores an authentication mode having a value including one of an authentication authorized mode and an authentication unauthorized mode; a GID request receiving section which receives a GID request message from a PLC apparatus; and a GID transmitting section which, if the authentication mode is the authentication authorized mode, transmits a GID corresponding to the PLC apparatus to the PLC apparatus. Thus, an authentication function is realized in a PLC media access control layer so as to distribute the GIDs between a PLC apparatus and an authentication apparatus, so that it is not necessary for a user to manually input a GID into the PLC apparatus. Further, the GIDs are distributed via the authentication apparatus, so that the user is capable of centrally managing the GIDs.;COPYRIGHT: (C)2007,JPO&INPIT
