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: Improved techniques are provided for managing and optimizing network resources and spectrum access in a Self-Organizing Network (SON). A Spectrum Access System (SAS) collects network-related information from a plurality of network sources, such as base stations and user equipments (UEs), to perform optimization and organization across different networks, network operators, and network technologies. In some embodiments, the SAS may use the network information and a Radio Environment Map to optimize TDD synchronization in the SON. In other embodiments, the SAS may use the network information to populate a global Neighbor Relation Table. The SAS also may use the network information to optimize one or more network parameters, such as Physical Cell Identities or Root Sequence Indexes, antenna parameters, transmit power levels, handover thresholds, channel assignments, and so on, for use in the SON.

Abstract: Techniques are provided for managing frequency access in a shared spectrum available to a radio local access network (RLAN) in a wireless network. A shared spectrum system may perform operations including retrieving a plurality of parameters for one or more high-priority users in the wireless network; computing, based on the retrieved parameters, a plurality of interference-to-noise power ratio (I/N) contours; storing the plurality of I/N contours in a database; receiving, from an RLAN device in the wireless network, a request for spectrum availability, wherein the received request includes at least a first value; extracting, based on the first value in the request for spectrum availability, an I/N contour from the database matching RLAN parameters; determining, based on the extracted I/N contour, available frequency information corresponding to the received request for spectrum availability; and transmitting, to the RLAN device, the available frequency information.

Abstract: A system and method is provided for a predictive connectivity layer. In the disclosed embodiments, resources, such as bandwidth, processing, and memory, at a network node are dynamically allocated based on one or more predicted user behaviors. A predicted user behavior may be determined based on one or more previous actions of a user or a group of users at the network node. For example, if a user accesses the network node to download a particular web site at the same time every morning, the predictive technique may determine that the user will attempt to download the same web site the next morning, and therefore cache a copy of the web site before the user's next attempt to access the network through the network node, Similarly, the network node may predict an amount of bandwidth or other resources to allocate based on previous behavior of one or more users.

Abstract: A method of allocating resources in a first wireless system, wherein the first wireless system shares a frequency spectrum with a second wireless system, is described. The method comprises detecting a level of interference to the second wireless system caused by the first wireless system on a first frequency within the spectrum; determining if transmission on the first frequency should be restricted based on the level of interference; and restricting transmissions in the first system on the first frequency if it was determined that transmission on the first frequency should be restricted while allowing normal use of the remaining portions of the frequency spectrum to continue in the first system. A system for allocating resources in a first wireless system, wherein the first wireless system shares a frequency spectrum with a second wireless system, is also described.

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.
