Title (EN) RADIO ACCESS NETWORK HANDOVER METHOD, BASE STATION, AND COMMUNICATION METHOD OF THE BASE STATION
(FR) PROCÉDÉ DE TRANSFERT SUR RÉSEAU D'ACCÈS RADIO, STATION DE BASE ET PROCÉDÉ DE COMMUNICATION DE LA STATION DE BASE
Abstract:
(EN) A radio access network handover method of a base station in a 5G radio access network (5G-RAN) is are disclosed. The method comprising: determining handing over a user equipment (UE) to an Evolved Universal Terrestrial Radio Access Network (E-UTRAN); transmitting a handover requirement message to an Access and Mobility Management Function (AMF); receiving a handover command message from the AMF and transmitting the handover command message to the UE, the handover message such that the UE is handed over from the 5G-RAN to the E-UTRAN; and performing indirect data forwarding to a base station in the E-UTRAN.
(FR) L'invention concerne un procédé de transfert sur réseau d'accès radio d'une station de base dans un réseau d'accès radio 5G (5G-RAN). Le procédé comprend : la détermination du transfert d'un équipement utilisateur (UE) à un réseau d'accès radio terrestre universel évolué (E-UTRAN) ; la transmission d'un message d'exigence de transfert à une fonction de gestion d'accès et de mobilité (AMF) ; la réception d'un message d'ordre de transfert depuis l'AMF et la transmission du message d'ordre de transfert à l'UE, le message de transfert étant tel que l'UE est transféré du 5G-RAN à l'E-UTRAN ; et la réalisation d'un transfert de données indirect vers une station de base dans l'E-UTRAN.
