Abstract

L'invention concerne un procédé de gestion de surveillance de messages de radiomessagerie exécuté par un dispositif mobile. Le procédé consiste à : se réveiller, au terme d'un cycle de réception discontinue (DRX) associé à une pluralité de technologies d'accès radio (RAT), RAT1…RATn, où n≥2; déterminer qu'un intervalle de temps actuel est dédié à la surveillance de messages de radiomessagerie associés à deux des RAT ou plus; déterminer qu'un PBRw1associé à la RAT1 est supérieur ou égal à un PBRwi associé à une autre RATi, où 2≥i≥n; ne pas surveiller des messages de radiomessagerie associés à chacune des RATi; augmenter chacun des PBRwi; et surveiller des messages de radiomessagerie associés à la RAT1.
