This paper discusses a spectrum sharing problem in multiple network operators (NOs). Most of the previous works have illustrated the dynamic spectrum allocation (DSA) gain achieved by utilizing the time or regional variations in traffic demand between NOs. In this paper, we introduce the functionalities required for the entities related with the spectrum allocation and propose a spectrum allocation algorithm. In the proposed spectrum allocation algorithm, the priority between NOs and the priorities of multiple class services are incorporated into the spectrum sharing metric (SSM), while also accommodating the urgent bandwidth request by proposing a negotiation procedure. It is shown that the proposed scheme allocates the spectrum dynamically, reflecting the long-term occupation ratio between NOs and the priorities of multiple class services.
