New Topology Management Scheme In Lte And 5g Networks

With the paradigm shift from the current 4G to the forthcoming 5G networks, novel network topology management interfaces become essential mainly due to the associated complexity introduced by the new softwarisation and virtualisation architecture. Moreover, the expected increasing number of users will require a very efficient management of the network resources. This paper proposes a new topology management scheme to report real-time topological information about the mobile users in a softwarised and virtualised 5G network. The proposed API has been designed and prototyped using Software Defined Radio (SDR) and the proven open source software OpenAirInterface and validated using commercial off-the-shelf user equipment.
