Abstract

L'invention concerne un procédé et un appareil de configuration de dispositif réseau, ainsi qu'un dispositif et un support de stockage, qui se rapportent au domaine technique des communications et qui sont utilisés pour limiter la concurrence du processus d'un MN configurant un CHO et du processus d'un SN configurant un CPC lorsqu'un UE est en connectivité double, afin qu'une pile de protocoles puisse conserver un mécanisme de traitement simple et efficace. Le procédé consiste à : à condition de déterminer qu'une opération de transfert conditionnel (CHO) est exécutée après une première durée prédéfinie ou que l'opération CHO est en cours d'exécution, envoyer un premier message de demande à un nœud secondaire, le premier message de demande servant à empêcher le nœud secondaire d'exécuter une opération de changement de PSCell conditionnel (CPC); exécuter l'opération CHO; et à condition de déterminer que l'opération CHO est terminée, envoyer un second message de demande au nœud secondaire, le second message de demande servant à indiquer que le nœud secondaire est autorisé à exécuter l'opération CPC.
