Abstract

L'invention concerne un procédé et un dispositif de stockage pour un contenu Internet. Le procédé comprend les opérations suivantes : dans le cas dans lequel le contenu Internet auquel un premier équipement utilisateur a demandé d'accéder est stocké dans une seconde station de base, une première station de base envoie un premier message de requête d'accès à la seconde station de base; et la première station de base reçoit le contenu Internet auquel le premier équipement utilisateur a demandé d'accéder, qui est envoyé par la seconde station de base selon le premier message de requête d'accès. Dans les modes de réalisation de la présente invention, dans le cas dans lequel le contenu Internet auquel un premier équipement utilisateur a demandé d'accéder est stocké dans une seconde station de base, une première station de base acquiert le contenu Internet auquel le premier équipement utilisateur a demandé d'accéder et l'envoie au premier équipement utilisateur, prenant conscience qu'une pluralité de stations de base partagent un contenu Internet stocké respectif. Puisque les capacités stockées par une pluralité de stations de base sont supérieures à celles stockées par une station de base unique, le taux de réussite d'accès d'un contenu Internet stocké dans la station de base peut être accru, et le taux d'utilisation de stockage est amélioré, permettant ainsi d'économiser efficacement le surdébit de transmission et de réduire le retard.
