Abstract: The disclosed embodiments provide a software-defined spectrum controller that may be used to dynamically and adaptively change rules and/or policies in a wireless network. The SDSC may dynamically change the rules or policies based on usage of spectrum and/or network resources or any other criterion, e.g., established by a service provider, to allow the service provider to use the spectrum and network resources more efficiently for delivering content and services to customers. In accordance with the disclosed embodiments, the SDSC may use at least one optimization algorithm to determine which policies or rules should be enforced at each of the network nodes in the wireless network. Based on the optimization algorithm, the SDSC may interact with other network nodes to dynamically change one or more of the rules or policies that are enforced in the service provider's network to provide content and services to customers.

Abstract: Embodiments provide an access point (AP) that includes a set of one or more base-station functions configured to connect a user equipment (UE) to the AP over a wireless communication interface; and a set of one or more core-network functions configured to provide services to the UE. The AP allocates an Internet Protocol (IP) address to the UE by using at least one Dynamic Host Configuration Protocol (DHCP) server that is external to the AP.

Abstract: Embodiments assign shared spectrum resources to access points. Embodiments group the access points into coexistence groups of access points, and generate a vertex graph including vertices that each represent one of the coexistence groups, where an edge connecting a pair of vertices in the vertex graph represents an overlap between coverage contours of a pair of coexistence groups represented by the pair of vertices, and the edge is assigned a weight that is proportional to the overlap as compared to other overlaps between coverage contours of other pairs of coexistence groups. Embodiments generate at least one vertex-colored graph by assigning a color to each vertex in the vertex graph, group the coexistence groups into groups of coexistence groups based on their corresponding assigned colors in the at least one vertex-colored graph, and map shared spectrum transmit frequencies to the groups of coexistence groups.
