Abstract

Les modes de réalisation de la présente invention se rapportent au champ des communications, et concernent un dispositif et un procédé de détermination de période de recherche, qui résolvent le problème d'un terminal qui consomme plus d'énergie du fait d'une recherche à de multiples reprises sur le principe de ne pas nécessiter une resélection de cellule. La solution spécifique est la suivante : un terminal acquiert un ensemble de cellules cibles, l'ensemble de cellules cibles comprenant des identifiants de cellule obtenus par le terminal par recherche dans une cellule voisine à un premier point de fréquence ; et le terminal détermine deux périodes de recherche correspondant à une période de réception discontinue actuelle (DRX) conformément au type du premier point de fréquence, le nombre total de points de fréquence pré-configurés dudit type et une relation de correspondance entre eux lorsqu'il est déterminé que l'ensemble de cellules cibles ne comprend pas d'identifiants de cellules adjacents à une cellule de desserte ; et le terminal détermine la plus grande période de recherche entre les deux périodes de recherche en tant que période de recherche cible du premier point de fréquence. Les modes de réalisation de la présente invention sont utilisés dans un processus de recherche de cellule.
