Abstract

Les stations mobiles peuvent déterminer la spécification d'une station de base dans une communication mobile, tandis qu'une limitation d'accès appropriée peut être obtenue. Un système de communication mobile comprend : des stations mobiles déterminant chacune des informations d'identification de station de base ; et une station de base qui transmet des informations de diffusion comprenant les informations d'identification de station de base définies pour chacune des spécifications d'une pluralité de services à fournir. Chacune des stations mobiles comprend : une unité de communication qui sert à recevoir les informations de diffusion de la station de base ; et une unité de commande qui sert à acquérir les informations d'identification de station de base incluses dans les informations de diffusion et à déterminer, sur la base des informations d'identification de station de base, les spécifications des services à fournir par la station de base.
