Abstract

La présente invention porte sur un procédé de récupération de connexions sans fil, un système de communication mobile, un équipement utilisateur (UE) et une station de base. Le procédé de récupération de connexions sans fil est utilisé pour le rétablissement de connexion du contrôle des ressources radio (RRC) de l'UE, le procédé comprenant les étapes suivantes : l'UE reçoit des informations de cellule rétablie et un paramètre temporel en provenance d'une station de base source; lorsque l'UE déclenche le processus de rétablissement de la connexion RRC, l'UE détermine si les informations de cellule rétablie sont valides conformément au paramètre temporel; si l'UE détermine que les informations de cellule rétablie sont valides, l'UE sélectionne la cellule cible de rétablissement conformément aux informations de cellule rétablie et à une règle de sélection; si l'UE détermine que les informations de cellule rétablie sont invalides, l'UE sélectionne la cellule cible de rétablissement seulement conformément à la règle de sélection.
