Sharing is Caring: Analysis of Hybrid Network Sharing Strategies for Energy Efficient Multi-Operator Cellular Systems

This paper introduces a novel analytical framework
for evaluating energy-efficient, QoS-aware network-sharing
strategies in cellular networks. Leveraging stochastic geometry,
our framework enables the systematic assessment of network
performance across a range of sharing paradigms, including
both conventional single-operator scenarios and advanced hybrid
strategies that enable full integration and cooperation among
multiple mobile network operators. Our framework incorporates
diverse user densities, rate requirements, and energy consumption
models to ensure comprehensive analysis. Applying our
results to real-world datasets from French mobile network
operators, we demonstrate that hybrid network sharing can yield
substantial energy savings, up to 35%, while maintaining quality
of service. Furthermore, our results allow us to characterizing
how the benefits of network sharing vary as a function of the geographical
and functional characteristics of the deployment area.
These findings highlight the potential of collaborative sharing
strategies to enhance operational efficiency and sustainability in
next-generation cellular networks.
