  • Publication number: 20230360062
    Abstract: A computer-implemented method for determining a credential sharing of a video streaming service account based on entropy of streaming data is described. The method includes determining an account entropy based on a viewing probability distribution for a total amount of content streamed for a defined account within a defined analysis period, grouping the total amount of content streamed into groups based on an account-stream characteristic that has probabilistic utility in determining the credential sharing, determining a group entropy for each of the groups, determining a watch-time variability based on the account entropy and each group entropy, and determining the credential sharing for the defined account based on the watch-time variability. The watch-time variability measures an increase in disorder when two or more groups of the groups are unrelated with respect to the account-stream characteristic.

  • Patent number: 11809416
    Abstract: Disclosed herein are embodiments providing query validation with automated query modification. In particular, the embodiments provide a computing system that receives a query and determines the query is sensitive. The computing system iteratively modifies the query until the query is not sensitive by modifying the query to increase a scope of the query, updating estimated query results based on the query as modified, and determining whether the query as modified is sensitive based on the estimated query results as updated. Upon determining that the query as modified is not sensitive, the computing system proceeds with the query as modified. Accordingly, the computing system improves query efficiency by automatically modifying a sensitive query.

  • Patent number: 11800498
    Abstract: A communication management resource (such as disposed at a network management node or other location) allocates bandwidth in a physical communication link to convey communication data associated with first customer premises equipment. In one implementation, the allocated bandwidth in the physical communication link is partitioned in accordance with wireless bandwidth supported by the first customer premises equipment. For example, in one embodiment, the allocated bandwidth of the physical communication link is mapped to convey corresponding data communicated over wireless bandwidth used by the first customer premises equipment. The communication management resource establishes a control channel over the physical communication link between the network management node and the first customer premises equipment. Via the control channel, the communication management resource then transmits a command over the control channel from the network management node to the first customer premises equipment.

  • Publication number: 20230336975
    Abstract: In certain embodiments, a (e.g., 5G) wireless network has a (e.g., CBSD) base station and any suitable number of instances of user equipment (UE). For each group of one or more UEs, one of the UEs is designated as a primary UE that stores UE context information for the other (secondary) UEs in the UE group. To connect to a secondary UE, the base station can retrieve the UE context information from the secondary UE's associated primary UE without having to retrieve the secondary UE's context information from the core network, thereby reducing backbone bandwidth usage and delays in connecting the secondary UE, especially when many secondary UE request connections within a short time interval.

  • Patent number: 11785472
    Abstract: In certain embodiments, one or more Citizens Broadband Radio Service (CBRS) service devices (CBSDs) may be migrated from their current Spectrum Access System (SAS) to a new SAS, where at least one existing PAL or GAA spectrum grant is transferred from the current SAS to the new SAS without waiting for a timer associated with the existing spectrum grant to expire. CBSDs may be migrated one at a time or multiple CBSDs of a single service provider may be migrated in a single process where the multiple CBSDs are identified by a shared organization ID associated with the service provider. In either case, a migrating CBSD can continue to use its previously existing spectrum grants after migrating to the new SAS without significant delay.

  • Patent number: 11784911
    Abstract: Methods and apparatus relating to the use of aggregated links, e.g., links in a bundle, are described. A normal link metric and a limited operation mode link metric a determined for a link bundle, the normal link metric having a lower value than the limited operational mode link metric. The status of links in a link bundle are monitored. Based on the number of currently operational links in a link bundle and a switching threshold, a decision is made whether to advertise the normal link metric, advertise the limited operation mode threshold or refrain from advertising any link metric. The use of the limited operation link metric facilitates the use of a partially failed link bundle providing an alternative routing path in the network that would not otherwise be available.

  • Patent number: 11777554
    Abstract: A network control device, e.g., a gNB, receives a message from a communications device, e.g. a UE, indicating that the communications device is experiencing an in-device coexistence (IDC) problem, e.g. in the 52.6 GHz-71 GHz frequency range with respect to NR-U and WiGig. The message is one of: i) an IDC assistance message indicating that the victim system is Wi-Gig or ii) an antenna panel switch message requesting that the network control device instruct the communications device to change the antenna panel that it uses for uplink NR signaling. The network control device generates and sends a response message to the communications device including: a selected new frequency to be used by the communications device for uplink NR signaling or a selected different antenna panel to be used by the communications device for uplink NR signaling. The communications device implements the change reducing or avoiding the IDC problem.

  • Patent number: 11770206
    Abstract: Methods and apparatus for supporting transmission bursts in unlicensed spectrum are described. Different sets of sub-bands within a downlink bandwidth portion of unlicensed spectrum can be, and sometimes are, occupied during different DL transmission bursts depending on channel availability. A user device is configured with channel usage information, e.g. N bitmaps, each bitmap indicating a different control channel resource allocation that may be used for communication with the UE, and/or reference signal information. The UE determines the occupied sub-bands in a DL transmission burst over the bandwidth portion, and determines control channel resource information based on the determined occupied sub-channels. The UE determines CSI-RS measurement locations based on determined sub-band occupancy. In some embodiments, the UE performs in-sync and out-of-sync evaluations based BLER threshold scaling factors, which are based on sub-band occupancy.
