Abstract

A dynamic spectrum arbitrage (DSA) system includes a dynamic spectrum policy controller (DPC) and a dynamic spectrum controller (DSC) that together dynamically manage the allocation and use of resources (e.g., spectrum resources) across different networks. The DSC component may include wired or wireless connections to eNodeBs, a mobility management entity (MME), and various other network components. These components may be configured to communicate and perform various mobility management operations to better manage and coordinate the handling (e.g., handoffs, hand-ins, backoff, etc.) of wireless devices as they are moved with respect to the allocated resources.
