Abstract

La présente invention concerne un procédé et un appareil de combinaison d'armoires d'une station de base compacte et d'unités radio distantes. Le procédé consiste à : configurer une première interface optique, qui correspond à une seconde interface optique existante d'une unité radio distante, sur une station de base compacte; et établir une connexion entre la station de base compacte et l'unité radio distante par l'intermédiaire de la première interface optique et de la seconde interface optique de sorte que la station de base compacte emploie la ressource radio de l'unité radio distante. Le problème de gaspillage des ressources de bande de base d'une station de base compacte peut ainsi être résolu en appliquant la présente invention.
