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: 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.

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: The disclosed embodiments provide improved methods and systems for managing spectrum by intelligently allocating specific channels from a pool of available spectrum channels used to serve content. For example, one or more sources may send “content service requests” over a network to request the delivery of content, which may be any type or amount of data. In accordance with the disclosed embodiments, a spectrum management service (SMS) receives a content service request for delivery of a content over a wireless access network, and it allocates spectrum for serving the requested content in the wireless access network based on at least one radio-frequency criterion and at least one criterion relating to the content. Further to the disclosed embodiments, the SMS issues a message to a transmission center in the wireless access network indicating the allocated spectrum that may be used to serve the content in the wireless access network.

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: The disclosed embodiments include methods, systems, articles of manufacture, and access devices configured to switch frequencies in a wireless access network. The techniques described in the disclosed embodiments may be used to facilitate efficient switching of frequencies in a dynamic spectrum environment. In one aspect, the disclosed embodiments may be implemented in a Long Term Evolution access network. The disclosed embodiments receive, by an access device, information allocating at least one frequency channel to be used by the access device. The disclosed embodiments also transmit, to one or more user equipment connected to the access device, an instruction for directing the one or more user equipment to look a first frequency channel. As a result, the disclosed embodiments allow efficient switching of frequencies even if the spectrum may be allocated dynamically.

The slave node may synchronize its clock to timing information provided by the master node.

Abstract: A wireless network emulation system undersamples log files when the conditions represented in the log files would require a faster refresh rate than the channel emulator can provide. A representative sample may be selected based on number of channel taps, delay spread, maximum value, or being first, last or otherwise identifiable within a group. The RF information from the selected sample is utilized as being representative of a group of related samples for a given time period corresponding to the refresh rate of the channel emulator.

Abstract: Missing or unwanted parameter data indicative of wireless network conditions in a log file or playback file is replaced with substitute parameter data. The substitute parameter data can be calculated based on other data in the log file or playback file, selected from pre-defined data in storage, and provided by a user. The substitute parameter data may also be customized by the user via an interface.

Abstract: One or more events recorded in one or more log files are recognized and processed by performing one or more operations including segmentation, modification, extraction, addition, and subtraction. The processed events are used to generate a playback file which is used by a channel emulator to perform testing.
