Abstract

L'invention concerne un procédé et un système d'accès réseau par terminal, lequel procédé consiste à : déterminer, lorsqu'un terminal reçoit un message de refus de connexion RRC ou un message de libération de connexion avec le côté RAN, la durée du délai de connexion au côté RAN lors d'une nouvelle connexion par le terminal; initialiser, lorsque la durée d'attente du terminal courant équivaut ou est supérieure à la durée du délai, une demande d'accès au côté RAN. Grâce à l'invention, on résout le problème insoluble de l'art antérieur lié à l'encombrement inéluctable des entités de réseau central suite au refus de la demande par tous les terminaux MTC courants survenant au moment de la nouvelle initialisation de la connexion.
