Description

本発明は、電力線通信モデムの障害を管理者に通報する障害通報システムに関する。   The present invention relates to a failure notification system for reporting a failure of a power line communication modem to an administrator.

相互接続性が保たれている電力線通信（ＰＬＣ）モデムが同一の電力線に接続している場合、ＰＬＣモデム同士は、ＰＬＣレイヤでは通信できるが、ユーザレベルでは、特に許可された場合を除いて通信できない。許可された場合とは、例えば、ＬＡＮ（構内通信網）を構築する場合である。このような扱いにより、例えば、大規模住宅で異なる住戸に属するＰＬＣモデム間の通信を排除でき、住戸単位でのＬＡＮの構築が可能になる。   When power line communication (PLC) modems that maintain interconnectivity are connected to the same power line, PLC modems can communicate at the PLC layer, but at the user level, except when specifically permitted. Can not. The case where permission is granted is, for example, a case where a LAN (private communication network) is constructed. By such handling, for example, communication between PLC modems belonging to different dwelling units in a large-scale house can be eliminated, and a LAN can be constructed in units of dwelling units.

各住戸でのホームゲートウエイと、契約しているインターネットサービスプロバイダ（ＩＳＰ）又は通信サービス業者への接続に障害又は認証エラー等が発生すると、当該住戸のクライアントは、電話又は郵便等のオフライン手続きによるしか、その障害をＩＳＰに通報する手段が無い。オンラインでの通報しか受け付けないＩＳＰには、障害の通報の手段が無いことになり、ＩＳＰ自身が障害に気付くのを待つしかない。   If a failure or an authentication error occurs in the connection to the home gateway in each unit and the contracted Internet service provider (ISP) or telecommunications service provider, the client of the unit will only be able to use offline procedures such as telephone or mail. There is no means to notify the ISP of the failure. An ISP that accepts only online notifications has no means of reporting a failure, and has to wait for the ISP to notice the failure.

本発明は、ネットワーク接続障害を通信サービス業者に迅速に通報する障害通報システムを提示することを目的とする。   An object of this invention is to show the failure notification system which notifies a communication service provider quickly of a network connection failure.

図２は、他のＰＬＣモデムからの緊急通報を中継する機能を具備するＰＬＣモデムの概略構成ブロック図を示す。ＰＬＣモデム５０は、ＰＬＣ通信の変復調回路５２を具備する。変復調回路５２は、電力線通信信号を受信すると、復調して、制御回路５４に供給する。制御回路５４は、受信信号が上述の緊急通報である場合、受信した緊急通報を一旦、ＲＡＭ５６に記憶し、当該緊急通報を当該緊急通報に含まれるＩＳＰに宛てた送信信号を生成する。この送信信号は、変復調回路５２によりＰＬＣ信号に変換されてホームゲートウエイ（例えば、ホームゲートウエイ３４ｃ）に転送され、当該ホームゲートウエイから宛先のＩＳＰ（例えば、ＩＳＰ２８）に送信される。   FIG. 2 shows a schematic block diagram of a PLC modem having a function of relaying an emergency call from another PLC modem. The PLC modem 50 includes a modulation / demodulation circuit 52 for PLC communication. When receiving the power line communication signal, the modem circuit 52 demodulates and supplies it to the control circuit 54. When the received signal is the above-mentioned emergency call, the control circuit 54 temporarily stores the received emergency call in the RAM 56 and generates a transmission signal for the emergency call addressed to the ISP included in the emergency call. This transmission signal is converted into a PLC signal by the modulation / demodulation circuit 52, transferred to a home gateway (for example, home gateway 34c), and transmitted from the home gateway to a destination ISP (for example, ISP 28).
