Integrated terrestrial and non-terrestrial 5G/6G networks
Bringing satellite and ground networks under one orchestration layer, so a device moves between them without noticing. We initiated this line of work and lead it technically.

The challenge
Terrestrial coverage stops where the build-out stops. Satellite coverage does not, but it has historically been a separate network: separate devices, separate contracts, separate operations teams. A vehicle, a vessel or a remote site crossing between them experiences two networks, not one.
Bridging them is not primarily a radio problem. It is an orchestration problem: deciding where a workload runs, which slice carries it, and when to move a session, across two domains with very different latency and capacity behaviour.
Our approach
We treat the terrestrial and non-terrestrial segments as one system under a single orchestration layer, with edge compute placed between the radio and the core so latency-bound work never has to cross the whole network.
Session continuity is handled above the access layer, so the handover between a ground station and a satellite link is a decision the network makes rather than an event the device has to survive.
