Title (EN) LONG TERM EVOLUTION (LTE) HANDOVER WITH THE SAME SECONDARY LINK
(FR) TRANSFERT D'ÉVOLUTION À LONG TERME (LTE) AVEC LA MÊME LIAISON SECONDAIRE
Abstract:
(EN) Techniques for minimizing interruption for UL and/or DL transmission via a secondary link during a handover on a primary link. In response to a handover indication, a UE, source BS and target BS may take one or more actions to maintain an existing connection between the UE and a secondary link. For example, the UE, source BS, and target BS may take one or more actions to maintain a connection between the UE and a WLAN AP (e. g., using the Sequence Number, SN, of the last PDCP packet forwarded to the WLAN-AP, or the highest received SN, HRW, and using the ciphering key of the source or target BS, or a permanent ciphering key of the WLAN-AP).
(FR) L'invention concerne des techniques pour minimiser une interruption de transmission UL et/ou DL par le biais d'une liaison secondaire pendant un transfert sur une liaison primaire. En réponse à une indication de transfert, un UE, une BS source et une BS cible peuvent effectuer une ou plusieurs actions afin de conserver une connexion existante entre l'UE et une liaison secondaire. Par exemple, l'UE, la BS source et la BS cible peuvent effectuer une ou plusieurs actions afin de conserver une connexion entre l'UE et un AP WLAN (par exemple, à l'aide du numéro de séquence, SN, du dernier paquet PDCP transmis au WLAN-AP, ou du SN reçu le plus élevé, HRW, et à l'aide de la clé de chiffrement de la BS source ou cible ou d'une clé de chiffrement permanente du WLAN-AP).
