Abstract

L'invention concerne un procédé et un eNodeB de rétablissement de connexion de commande de ressources radioélectriques (RRC). Le procédé comporte les étapes suivantes: un eNodeB détecte si une transmission de données est normale entre l'eNodeB et un équipement d'utilisateur (UE); lorsque la transmission de données est anormale, l'eNodeB envoie une signalisation à l'UE pour permettre à l'UE de procéder à un rétablissement de connexion RRC d'après la signalisation; l'eNodeB reçoit et traite la demande de rétablissement de connexion RRC émise par l'UE. La présente invention permet à l'eNodeB de déclencher activement l'amorce par l'UE d'un rétablissement de connexion RRC lorsque la transmission de données est anormale entre l'eNodeB et l'UE, évitant ainsi l'interruption de la transmission de données et réduisant l'impact sur la transmission de données.
