Abstract

Des modes de réalisation de la présente demande concernent un procédé d'enregistrement de localisation et un dispositif terminal ; lorsqu'une cellule diffuse une pluralité de TAC, au moyen d'une comparaison entre la pluralité de TAC et de localisations d'enregistrement de dispositif terminal, l'initiation du processus d'enregistrement d'emplacement est réduite au minimum, réduisant le surdébit de signalisation. Le procédé d'enregistrement de localisation comprend les étapes suivantes : un dispositif terminal obtient une liste TAC d'une cellule cible ; selon ladite liste TAC de ladite cellule cible et une liste TAC enregistrée par ledit dispositif terminal, le dispositif terminal détermine s'il faut lancer un processus d'enregistrement de localisation.
