Abstract

L'invention concerne un procédé mis en œuvre par un équipement utilisateur multi-SIM. L'équipement utilisateur détermine d'abord un conflit entre deux intervalles de mesure appartenant à des séquences d'intervalles de mesure respectives configurées par différents réseaux. Ensuite, une règle de priorité selon laquelle un intervalle de mesure ayant une plus longue MGRP aura une plus haute priorité dans la paire en conflit est utilisée pour déterminer la priorité de ces deux intervalles de mesure. Après cela, l'intervalle de mesure ayant une plus basse priorité pourra être annulé. L'invention concerne également un procédé mis en œuvre par un nœud de réseau concernant la priorité d'intervalles de mesure en conflit configurés par différents réseaux.
