L'invention concerne un procédé de gestion de liaisons radio, un équipement utilisateur et une station de base. Ledit procédé comprend : la réception d'un ensemble d'informations de liaisons radio envoyé par une station de base, cet ensemble d'informations de liaisons radio servant à indiquer au moins une liaison radio d'un gestionnaire de liaisons radio (RLM) à exécuter ; l'exécution du RLM sur au moins une liaison radio dudit RLM à exécuter, en fonction de l'ensemble d'informations de liaisons radio ; et le lancement d'une procédure de rétablissement d'un protocole de commande de ressources radio (RRC) lorsqu'au moins une première liaison radio parmi celles du RLM à exécuter génère une défaillance de liaison radio (RLF). Le procédé de gestion de liaisons radio, l'équipement utilisateur et la station de base décrits par les modes de réalisation de la présente invention permettent le maintien efficace d'une pluralité de liaisons radio de l'UE et le lancement d'un rétablissement RRC lorsque cela est nécessaire, ce qui préserve mieux la qualité de service de l'UE.
