Abstract

La présente invention se rapporte au domaine des communications. L'invention porte sur un procédé et sur un appareil de traitement pour un échec de transfert intercellulaire, sur un dispositif de communication et sur un support de stockage. Le procédé est appliqué à un dispositif terminal. Le procédé consiste : dans le cas où un transfert par double pile de protocoles active (DAPS) est défaillant, à transmettre un rapport de défaillance de liaison radio (RLF) à une cellule source. Selon le procédé fourni par la présente invention, lorsque le transfert de double pile DAPS est défaillant, le dispositif terminal rapporte le rapport de défaillance RLF à la cellule source de telle sorte que la cellule source puisse obtenir les informations associées de l'échec de transfert de double pile DAPS, et déclenche un schéma d'optimisation de robustesse de mobilité de manière opportune.
