Abstract
The integration of Non Terrestrial Networks into 5G and beyond cellular systems has introduced a significant paradigm shift, enabling ubiquitous connectivity and extending services to previously unconnected and underserved remote regions. In particular, Low Earth Orbit satellites, operating close to the Earth surface, can provide communication latency comparable to that of terrestrial networks. However, due to their high mobility, LEO satellites trigger frequent handovers, which degrade users quality of experience and increase signaling overhead. In this work, our objective is to minimize the number of handovers in a LEO satellite system while preventing satellite overloading. We formulate the problem within a game theoretic framework and apply the Spatial Adaptive Play algorithm to obtain a handover efficient and load balanced solution. Additionally, we propose a low complexity heuristic algorithm to achieve similar objectives with reduced computational overhead.
Low Earth orbit mobile satellite system (LEO-MSS) is a major system that provides communication support for mobile terminals beyond the coverage of terrestrial communication systems. However, passive handover happens frequently, caused by the quick movement of LEO satellites, making it hard to guarantee quality of serv...

In the uplink, NR-DC outperforms satellite-only operation but remains below terrestrial-only performance, indicating that the benefit depends on traffic direction and transport behaviour, and an integrated terrestrial–LEO 5G network using a customised Simu5G framework.

A rolling-horizon migration-aware dynamic greedy control node placement algorithm (RH-MA-DGCNP) is proposed, which updates the CN placement and the affiliation between access-layer satellites and CNs at each reconfiguration epoch while jointly considering the handover delay and the migration delay caused by transferrin...

The deployment of Ultra-Dense Networks (UDNs) in 5G systems is to meet the growing demand for high data rates and massive connectivity. However, the dense deployment of small cells increases handover frequency, leading to challenges such as handover failures (HOF), unnecessary handovers, and the ping-pong effect, leadi...

Low Earth orbit (LEO)-based non-terrestrial networks (NTN) are emerging as a key component of 6G systems, enabling seamless connectivity over wide geographical areas. However, in Earth-moving cell (EMC)-based NTN scenarios, rapid beam movement induces frequent cell boundary crossings, resulting in excessive handover op...
