Abstract

La présente invention se rapporte à un procédé de transmission de données et à un appareil de transfert de données. La présente invention appartient au domaine technique des communications. Elle est apte à réduire la consommation de puissance de l'appareil de transfert de données. Le procédé selon l'invention comprend les étapes suivantes : un appareil de transfert de données reçoit des données envoyées par au moins un client, au moyen d'un module d'accès aux données; il transmet les données reçues au moyen du module d'accès aux données, à un module de stockage temporaire de données, en vue de leur stockage; quand il est déterminé qu'un statut de stockage des données qui sont stockées dans le module de stockage temporaire de données répond à une exigence de transmission, l'appareil de transfert de données transmet une instruction de transmission de données, à un module de transmission de données, au moyen du module de stockage temporaire de données; et, sur la base de l'instruction de transmission de données, l'appareil de transfert de données transmet les données qui sont stockées dans le module de stockage temporaire de données, au moyen du module de transmission de données. La présente invention peut être mise en œuvre dans un module de transmission de données.
