Answer Posted / parfait
RNC contrôle les Node B et le BSC contrôle les BTS
RNC est connecté aux autres RNC par l’interface Iur or que les BSC ne sont pas connectées entre elles
le RNC Gère la macro diversité
Un RNC peut jouer 2 rôles: serving ou drift
Les protocoles supportés sont différents. Pour le BSC on a par exemple: LAPD, MTP, SCCP,… alors que pour le RNC on a par exemple NBAP, RRC, RLC-C, RANAP, …
4 interfaces de connections pour le RNC : Iub, Iur, Iucs, Iups contre 2 pour le BSC : Abis et Ater
