Abstract
(EN)
Systems, methods and computer software are disclosed for providing core High Availability (HA) for a wireless network. In one embodiment, a method is disclosed, comprising: providing a first node, a second node and a third node; allocating a set of locally generated Tunnel Endpoint Identifiers (TEIDs) for UEs anchored on the second node; detecting, by a first node, a second node having a connectivity issue; and migrating a User Equipment (UE) connected to the second node to a third node which is accessible; using the set of locally generated TEIDs to identify the UE migration.
(FR)
L'invention concerne des systèmes, des procédés et des logiciels pour fournir une haute disponibilité (HA) de cœur pour un réseau sans fil. Dans un mode de réalisation, l'invention concerne un procédé comprenant : la fourniture d'un premier noeud, d'un second noeud et d'un troisième noeud ; l'attribution d'un ensemble d'identifiants de point d'extrémité de tunnel (TEID) générés localement pour des UE ancrés sur le second noeud ; la détection, par un premier noeud, d'un second noeud présentant un problème de connectivité ; et la migration d'un équipement utilisateur (UE) connecté au second noeud à un troisième noeud qui est accessible ; l'utilisation de l'ensemble de TEID générés localement afin d'identifier la migration de l'UE.
