Abstract

La présente invention concerne un procédé d'accès aléatoire, un appareil, et un support de données. Dans le procédé d'accès aléatoire, un préambule réservé est déterminé, le préambule réservé étant un préambule désigné pour un terminal multi-SIM ; et le préambule réservé est envoyé. Un préambule réservé envoyé par un terminal multi-SIM est acquis, le préambule réservé étant un préambule désigné pour un terminal multi-SIM, et le terminal multi-SIM étant un terminal ayant une pluralité de cartes SIM installées ; sur la base du préambule réservé, le terminal qui a envoyé le préambule réservé est identifié en tant que terminal multi-SIM ; et l'accès est autorisé pour le terminal multi-SIM. Au moyen de la présente invention, lorsqu'un terminal multi-SIM envoie un préambule réservé, un réseau reconnaît le terminal multi-SIM au moyen du préambule réservé, et est ainsi apte à effectuer un traitement ciblé sur une opération autonome du terminal multi-SIM.
