Small cell Access Points (SAPs) can offload macrocell traffic, improve indoor coverage and cell-edge user performance, and boost network capacity. In this paper, the authors investigate the problem faced by the Mobile Network Operator (MNO) on how to properly incentivize the existing private SAPs to serve extra roaming macrocell users. They propose a refunding framework for small cell networks with limited-capacity backhaul, where Small cell Holders (SHs) receive refunding from the MNO and then admit macrocell users. Specifically, they formulate a two-stage refunding-admission game with MNO being the leader and SHs being the followers.
