Abstract

La présente divulgation se rapporte au domaine technique des communications et en particulier à un procédé et un appareil d'enregistrement d'informations, un procédé et un appareil de réception d'informations, un terminal, un dispositif de réseau et un support de stockage. Le procédé d'enregistrement d'informations consiste à : lorsqu'une défaillance de liaison radio (RLF) ou une défaillance de transfert se produit, enregistrer des informations LTM de mobilité déclenchées par la couche 1 ou la couche 2. Selon la présente divulgation, un terminal peut enregistrer des informations LTM dans le cas d'une RLF ou d'une défaillance de transfert, de sorte que les informations LTM peuvent être ensuite envoyées à un dispositif de réseau selon des exigences ou une demande de dispositif de réseau. Par comparaison avec le terminal enregistrant des informations relatives à une RLF et à une défaillance de transfert dans le cas d'une RLF ou d'une défaillance de transfert, les informations LTM peuvent être utilisées pour que le dispositif de réseau détermine avec précision un état lié à LTM du terminal, permettant de s'assurer que le dispositif de réseau peut déterminer rapidement et avec précision, sur la base des informations LTM, s'il faut exécuter une LTM, ajuster des configurations LTM et effectuer d'autres opérations.
