Abstract

La présente invention concerne un procédé et un dispositif de mise à jour de cellules voisines destiné à résoudre le problème qui est qu'un terminal ne peut pas obtenir d'informations relatives à des cellules voisines mises à jour. Dans les modes de réalisation de la présente invention, lorsqu'un dispositif côté réseau satisfait une condition prédéfinie, des informations relatives à des cellules voisines diffusées par une présente cellule sont mises à jour sur la base d'informations d'image de filé d'étoiles, d'informations relatives à un mappage de bandes de fréquence et d'informations de mappage d'identifiants de cellule physique ; et il est ordonné, au moyen d'un processus de radiomessagerie, à tous les terminaux dans la présente cellule d'acquérir les informations relatives à des cellules voisines mises à jour diffusées par la présente cellule, ce qui permet de commander efficacement la mobilité d'un terminal dans un état de veille ou un état inactif.
