Summary:The present invention relates to a communication method applied to an intelligent advanced metering infrastructure (AMI) system so as to enable metering data collected from an electronic power meter to be wirelessly transmitted to a coordinator via routers, and relates to a technique enabling communication via channels having excellent communication qualities. Such present invention comprises the steps in which: routers check channel quality data for a currently used channel and idle channels, and transmits the results of the checking and GPS data of the routers themselves to a coordinator; the coordinator checks, on the basis of the channel quality data, whether or not handoff requirements are met; and if, as a result of the checking, the coordinator determines that handoff requirements are met, the coordinator issues, to the routers, a channel change command ordering for the currently used channel to be changed to the idle channel having the most excellent communication quality. La présente invention concerne un procédé de communication appliqué à une infrastructure de comptage avancé (AMI) intelligente, qui permet à des données de comptage collectées à partir d'un compteur de puissance électronique d'être transmises sans fil à un coordinateur via des routeurs. L'invention concerne également une technique permettant une communication par l'intermédiaire de canaux, dotée d'excellentes qualités de communication. Le procédé selon l'invention comprend les étapes suivantes : des routeurs vérifient des données de qualité de canal d'un canal actuellement utilisé et de canaux inactifs, et transmettent les résultats de la vérification et des données GPS des routeurs eux-mêmes à un coordinateur; sur la base des données de qualité de canal, le coordinateur vérifie si des exigences de transfert sont satisfaites ou non; et si, en conséquence de la vérification, le coordinateur détermine que les exigences de transfert sont satisfaites, il transmet, aux routeurs, un ordre d'instruction de changement de canal pour que le canal actuellement utilisé soit le canal inactif doté de la meilleure qualité de communication. 본 발명은 지능형 원격 검침 시스템(AMI)에 적용되어 전자식 전력량계로부터 수집되는 검침정보를 라우터들을 통해 코디네이터에 무선으로 전송하는 통신 방법에 있어서, 통신 품질이 우수한 채널을 통해 통신할 수 있도록 한 기술에 관한 것이다. 이러한 본 발명은, 라우터들이 현재 사용중인 채널과 유휴 채널들에 대한 채널품질 정보를 체크하여 그 체크 결과와 자신의 GPS 정보를 상기 코디네이터에 전송하는 단계; 상기 코디네이터가 상기 채널품질 정보를 근거로 핸드오프 조건인지 확인하는 단계; 및 상기 확인 결과, 상기 코디네이터에서 핸드오프 조건으로 판단될 때 상기 코디네이터는 상기 라우터들에게 현재 사용중인 채널을 통신 품질이 가장 우수한 유휴 채널로 변경하라는 채널 변경명령을 하달하는 단계를 포함하는 것을 특징으로 한다.
