Abstract

La présente invention concerne un procédé, un appareil, et un terminal de connexion RRC (gestion des ressources radio). Ledit procédé comprend les étapes suivantes : un équipement d'utilisateur (UE) dans un état de repos, lors de l'initiation d'un accès aléatoire à une station de base, met fin à une opération de mesurage d'une qualité sans fil et une opération de sélection et de resélection de cellule; l'UE détermine si un accès aléatoire a réussi; si l'accès aléatoire de l'UE a réussi, l'UE entre alors dans un mode connecté; si l'accès aléatoire de l'UE échoue, l'UE reprend alors l'opération de mesurage d'une qualité sans fil et l'opération de sélection et de resélection de cellule. La présente invention résout le problème lié, dans l'état de la technique, au fait qu'un équipement d'utilisateur (UE) dans un état de repos doit déterminer une qualité sans fil et une sélection/resélection de cellules. L'invention réduit ainsi la consommation d'énergie de l'UE tout en améliorant le taux de réussite de l'établissement d'une connexion RRC.
