5.21.1.3 N2 TNL association selection

Taught in 27. Overload, energy, deployment and the rest (The 5G system architecture, in depth).

The 5G-AN node shall consider the following factors for selecting a TNL association for the AMF for the initial N2 message e.g. N2 INITIAL UE MESSAGE:

  • Availability of candidate TNL associations.
  • Weight factors of candidate TNL associations.

The AMF may use any TNL association intended for non-UE associated signalling for initiation of the N2 Paging procedure.
