Abstract

Un terminal de gestion locale (LMT) portable ou un détecteur de position connecté à ce terminal est placé dans un lieu géographiquement proche d'un nouveau noeud à connecter initialement à un réseau. Le terminal LMT peut aussi être désigné comme terminal de configuration initiale (ICT). Le terminal LMT est équipé d'un type de fonction de détection d'une position géographique, notamment le système mondial de localisation (GPS). Le terminal LMT est amené à établir une communication avec un noeud de gestion réseau. Le terminal LMT détermine sa position géographique (notamment via GPS), et retransmet les données de position y afférentes au noeud de gestion réseau. Le noeud de gestion utilise les données de position associées au terminal LMT pour déterminer où sont localisés le terminal LMT et le nouveau noeud, et identifie le nouveau noeud via les données de position. En identifiant le nouveau noeud, le noeud de gestion détermine les données de configuration initiale de site du nouveau noeud et les retransmet au terminal LMT. A son tour, le terminal LMT transfère les données de configuration initiale de site au nouveau noeud en vue de la configuration initiale du noeud. En suivant la configuration initiale du nouveau noeud, une autre configuration du noeud peut être réalisée à l'aide d'au moins une partie des données de configuration initiale.
