Abstract

La présente invention concerne un procédé et un système permettant à un équipement d'utilisateur d'accéder à un nœud B de rattachement. Lorsque l'équipement d'utilisateur entre dans la zone de desserte d'un nœud B de rattachement restreint auprès duquel il n'est pas accrédité, ledit procédé comporte les étapes suivantes : l'équipement d'utilisateur apprend par une détection que le nœud B de rattachement auquel appartient la zone de desserte dans laquelle il entre est un nœud B de rattachement restreint (S501) ; l'équipement d'utilisateur envoie un message à un réseau central, le message véhiculant les informations sur la localisation actuelle de l'équipement d'utilisateur (S503) ; l'équipement d'utilisateur reçoit une demande de radiorecherche lancée par le réseau central et établit la liaison avec le nœud B de rattachement restreint, la demande de radiorecherche étant lancée via un sous-système du nœud B de rattachement correspondant aux informations de localisation lorsque le réseau central obtient des données de voie descendante qui doivent être envoyées à l'équipement d'utilisateur (S505). Selon la solution technique de la présente invention, ledit équipement d'utilisateur peut faire l'objet d'une radiorecherche efficace, assurant ainsi la réussite de la communication et évitant efficacement le gaspillage des ressources de radiorecherche.
