Title: SYSTEMS, METHODS, AND DEVICES FOR HANDLING STICKINESS OF UE-SPECIFIC RAN-CN ASSOCIATION
Abstract:
An access network (AN) node of a wireless system connects to a core network via a plurality of transport network layer (TNL) associations between the AN node and a network function. For a user equipment (UE) in a connected state with the network function through a first interface (N1 interface), the AN node maintains a binding between a second interface (N2 interface) application layer protocol (NGAP) association for the UE and a corresponding TNL association of the plurality of TNL associations. The AN node determines, with the UE in the connected state, an update of the binding by the network function. In response to the update by the network function, the AN node changes or releases the binding.
