Dialogue between Satellite and Cellular Networks: Pricing Game for Data Offloading Assisted by Ultra-dense LEO Constellations

Due to the limited backhaul capacity of traditional small cells (TSC), it is non-trivial for the traditional operator (TO) to satisfy the increasing data demand of users. To relieve this issue, we propose a data offloading scheme, where the TO offloads TSC users to LEO-based small cells owned by the satellite operator for satellite-backhauled network access. An iterative optimal algorithm based on the Stackelberg game is developed to maximize both operators' revenues. Simulation results show the effectiveness of our scheme.
