Title (EN) CONTEXT TRANSFER VIA LAST VISITED RAN NODE
(FR) TRANSFERT DE CONTEXTE PAR L'INTERMÉDIAIRE DU DERNIER NŒUD RAN VISITÉ
Abstract:
(EN) It is provided a method comprising monitoring if a new base station receives, from a terminal, location update information for the terminal, an anchor base station identifier, a context identifier, and at least one of a last visited cell identifier and a last visited base station identifier; checking if a first direct connection between the new base station and the anchor base station exists if the location update information and the anchor base station identifier are received; instructing the new base station to request the context from the anchor base station via the last visited base station if the first direct connection does not exist and the at least one of the last visited cell identifier and the last visited base station identifier is received; wherein the request for the context from the anchor base station comprises the anchor base station identifier and the context identifier.
(FR) L'invention concerne un procédé consistant à surveiller si une nouvelle station de base reçoit, en provenance d'un terminal, des informations de mise à jour de localisation pour le terminal, un identifiant de station de base d'ancrage, un identifiant de contexte et l'identifiant de la dernière cellule visitée et/ou l'identifiant de la dernière station de base visitée ; à vérifier si une première connexion directe entre la nouvelle station de base et la station de base d'ancrage existe si les informations de mise à jour de localisation et l'identifiant de station de base d'ancrage sont reçus ; à ordonner à la nouvelle station de base de demander le contexte à la station de base d'ancrage par l'intermédiaire de la dernière station de base visitée si la première connexion directe n'existe pas et que l'identifiant de la dernière cellule visitée et/ou l'identifiant de la dernière station de base visitée sont reçus ; la demande de contexte à la station de base d'ancrage comprenant l'identifiant de station de base d'ancrage et l'identifiant de contexte.
