Abstract

Les modes de réalisation de la présente demande se rapportent à un procédé et à un dispositif d'identification destinés à un terminal. Le procédé consiste : à déterminer, par un terminal de premier type, une RO cible, la RO cible étant une RO ne pouvant pas être utilisée par un terminal de second type ; et à envoyer, par le terminal de premier type, un préambule à un dispositif côté réseau sur la RO cible, de telle sorte que le dispositif côté réseau détermine le type du terminal de premier type en fonction de la RO cible. Dans le procédé, seul un terminal de premier type peut envoyer un préambule sur une RO cible, et un terminal de second type ne peut pas envoyer un préambule sur la RO cible. Ainsi, un dispositif côté réseau peut déterminer le type du terminal de premier type en fonction de la RO cible sur laquelle le préambule est reçu.
