Abstract

L'invention concerne un procédé de sélection d'une tranche de réseau et un dispositif associé capable de résoudre un problème technique dans lequel une sélection d'une tranche de réseau ne peut pas être effectuée lors de l'initiation de nouvelles informations de requête par un terminal. Le procédé comprend les étapes suivantes : un nœud de réseau d'accès radio reçoit des informations de requête transmises par un terminal ; le nœud de réseau d'accès radio détermine, selon les informations de requête, une seconde fonction de commande partagée d'une seconde tranche de réseau à laquelle le terminal doit être connecté ; et le nœud de réseau d'accès radio détermine si la seconde fonction de commande partagée est identique à une première fonction de commande partagée, la première fonction de commande partagée étant une fonction de commande partagée sélectionnée par le terminal lors de la fixation à une première tranche de réseau.
