Abstract

L'invention concerne un procédé et un dispositif de détection de restriction d'accès, capable de résoudre le problème d'un dispositif de terminal incapable de transmettre normalement une détection de restriction d'accès antérieure par l'intermédiaire de petits paquets de données en raison de paramètres de restriction d'accès désadaptés, ce qui permet d'éviter un cas dans lequel le dispositif de terminal doit lancer de manière répétée une détection de restriction d'accès avant la transmission de petits paquets de données. Un dispositif de réseau détermine d'abord au moins un groupe de premiers paramètres de restriction d'accès correspondant à un schéma de transmission de petits paquets de données. Le dispositif de réseau transmet au dispositif de terminal un premier message comprenant le ou les groupes de premiers paramètres de restriction d'accès. L'utilisation du procédé décrit dans les modes de réalisation de la présente invention augmente le taux de réussite d'une détection de restriction d'accès avant la transmission de données effectuée par le dispositif de terminal sur la base d'un schéma de transmission de petits paquets de données, et augmente le taux d'utilisation des ressources pour un réseau de communication radio.
