Abstract

Les modes de réalisation de la présente invention concernent la technologie des communications sans fil, et en particulier un procédé, un système et un dispositif de transmission de données. Dans l'état de la technique, lorsqu'une unité radio distante (RRU) multimode accède au côté station maître, il est difficile de connaître la norme d'interface du côté station maître, ce qui fait qu'il est impossible de transmettre des données selon le format de données correspondant à la norme d'interface du côté station maître ; par conséquent la difficulté de transmission de données est accrue, et le taux de succès de la transmission de données est réduit. Les modes de réalisation de la présente invention sont utilisés pour résoudre ce problème existant. Le procédé des modes de réalisation de la présente demande comprennent les opérations suivantes : l'unité de bande de base de bâtiment (BBU) confirme la norme d'interface utilisée de l'interface connectée à la RRU ; selon la norme d'interface confirmée, ladite BBU envoie un message d'indication de norme d'interface à la RRU connectée à la BBU elle-même ; la RRU connectée à la BBU elle-même se voit indiquer de confirmer la norme d'interface selon ledit message d'indication de norme d'interface, et d'envoyer des données à l'aide du format de données de la norme d'interface confirmée. L'utilisation des modes de réalisation de la présente invention permet d'améliorer le taux de succès de l'accès de la RRU à la station maître.
