Abstract

L'invention concerne un procédé et un dispositif de configuration de mise en réseau fusionnée. Le procédé comprend les étapes consistant à : obtenir au moins une zone de couverture améliorée d'un premier réseau, la zone de couverture améliorée étant une zone de couverture dans laquelle la qualité de signal ne satisfait pas un objectif de qualité de signal (101) ; déterminer une zone avec une couverture de colocalisation d'un site d'un second réseau et d'un site du premier réseau selon la ou les zones de couverture améliorées (102). En utilisant le procédé et le dispositif de configuration de mise en réseau fusionnée selon la présente invention, une mise en réseau fusionnée du premier réseau et du second réseau peut être établie librement, de sorte que le second réseau peut efficacement s'ajouter à une pluralité de zones d'accès sans fil ou de zones de couverture clés du premier réseau afin d'améliorer l'expérience de l'utilisateur du premier réseau.
