  • Patent number: 12279178
    Abstract: Locations and azimuths of cells of a communication network can be estimated, determined, and validated. Cell attribute management component (CAMC) can estimate, determine, and/or validate cell locations based on analysis of timing advance (TA) measurement data and/or location data associated with devices associated with base stations associated with cells. CAMC can estimate azimuth of a cell associated with a base station based on analysis of a validated cell location of the cell and location data associated with devices associated with the cell. CAMC can determine whether a recorded azimuth of the cell is validated based on analysis of the estimated azimuth of the cell and the recorded azimuth of the cell. CAMC can tag the recorded azimuth of the cell as validated if applicable azimuth accuracy criteria is met, inaccurate if applicable azimuth criteria is not met, or omni if the cell is an omni cell.

  • Patent number: 12279153
    Abstract: The described technology is generally directed towards a short message service (SMS) congestion manager that can evaluate, predict, and mitigate SMS congestion. The SMS congestion manager can be implemented within a short message services function (SMSF) of a fifth generation (5G) or subsequent generation cellular network. The SMS congestion manager can monitor a volume of non-access stratum (NAS) SMS messages in order to detect potential overload conditions wherein the volume of messages exceeds a capability of a network function. In response to detecting potential overload conditions, the SMS congestion manager can inhibit messages directed to the network function in order to prevent overloads from developing. The SMS congestion manager can use machine learning to learn to detect the potential overload conditions as well as to learn actions to take to address the potential overload conditions.

  • Patent number: 12279172
    Abstract: In 6G, there are multiple radios that can cover the same location at any time, and yet radio failure can occur. However, a mobile edge computing (MEC) platform can increase the footprint of adjacent radios to compensate for a failed radio. To reduce the failure interruption and maintain a quality of experience for a subscriber, the MEC can utilize a virtual session capability to communicate radio change of service characteristics to a service provider. Consequently, the change in service characteristics can comprise an expanded coverage area for adjacent radios such that a mobile device of the subscriber can take advantage of the expanded coverage area without experiencing an interruption in service.

  • Patent number: 12273778
    Abstract: The disclosed technology is directed towards switching the primary cell in a carrier aggregation scenario to improve performance. Measurement data of a mobile device (user equipment) is evaluated with respect to one or more various criteria such as cell carrier bandwidth, cell carrier load, cell-related capability and other carrier data (e.g., dynamic spectrum sharing versus clean, time division duplex or frequency division duplex), and others. Device conditions such as overheating can be considered as well. The evaluation results in a ranking of primary cell candidates. If a more optimal primary cell (candidate) is available, the primary cell in the carrier aggregation combination is switched to the candidate that is ranked the highest. Switching can be relatively very fast, such as based on already existing layer-1 (L1) and/or layer-2 (L2) measurement data. Layer-3 (L3) measurement data also can be obtained on demand, for example, to use in the evaluation.
