1. A method for providing core High Availability (HA) for a wireless network, 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.
