Abstract

La présente invention concerne un procédé d'économie d'énergie pour une station de base, et une station de base, qui se rapportent au domaine des communications et servent à résoudre les problèmes liés aux grandes quantités de traitement manuel et aux coûts fixes relativement importants en main d'œuvre lors des économies d'énergie de la station de base. Le procédé comprend : dans les cas où la désactivation d'économie d'énergie doit être effectuée sur une première cellule, l'envoi, par une station de base à laquelle appartient la première cellule, d'un message de requête de compensation à une station de base à laquelle appartient une seconde cellule, le message de requête de compensation servant à demander à la seconde cellule de compenser pour la première cellule; lorsque la station de base à laquelle appartient la première cellule reçoit un message de réponse de compensation envoyé par la station de base à laquelle appartient la seconde cellule et qu'il est déterminé d'après le message de réponse de compensation que la seconde cellule doit servir à effectuer une compensation, l'envoi, par la station de base à laquelle appartient la première cellule, d'un premier message de reconnaissance de compensation à la station de base à laquelle appartient la seconde cellule, le premier message de reconnaissance de compensation servant à indiquer que la seconde cellule doit servir à compenser pour la première cellule; et la mise en œuvre de la désactivation, par la station de base à laquelle appartient la première cellule, de l'économie d'énergie sur la première cellule.
