Abstract

L'invention concerne un procédé et un dispositif de mise en cache de ressources. Le procédé comprend les étapes suivantes : une station de base actuelle reçoit une requête de service envoyée par un premier terminal ; la station de base actuelle détermine le fait de savoir si les ressources inactives de la station de base actuelle satisfont à une exigence d'un service demandé par la demande de service ; et si ce n'est pas le cas, la station de base actuelle attribue des ressources devant être attribuées sur la station de base actuelle au premier terminal, au moins certaines ressources dans les ressources devant être attribuées sont des ressources partagées acquises à partir d'un ensemble de stations de base adjacentes à la station de base actuelle. Des modes de réalisation de la présente invention résolvent un problème de faible efficacité d'attribution de ressources dans la technique apparentée, de manière à obtenir l'effet d'amélioration de l'efficacité d'attribution de ressources.
