  • Patent number: 12273961
    Abstract: The disclosed technology is directed towards detecting improbable speeds of a mobile device, which can indicate fraudulent activity with respect to the mobile device. Radio access network events and call detail records are processed to determine when a mobile device “travel jumps” between locations at improbable speeds. Events corresponding to handovers between adjacent cells are filtered out. For events corresponding to changed cell towers that are non-adjacent, further processing is performed to determine the speed of the mobile device travel between the cells. A first speed threshold is selected based on possible air travel (a cell near an airport) or a second non-air travel speed threshold is selected. If the speed of the mobile device exceeds the selected speed threshold, a travel jump is determined. Exceptions can be made for gaps in connectivity due to topography (known inconsistent reception areas) and for a mobile device shutting down and restarting.

  • 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.

  • Patent number: 12267324
    Abstract: Authorization for access to an application server and associated communication service can be desirably managed. When a device attempts to access an application server and service, an authorization server generates an encrypted token, comprising device identifier information, and communicates the token to the device. The device communicates the token to the application server. The application server communicates the token to the authorization server. The authorization server determines whether the device is validated to access the application server and service based on the encrypted token, private decryption key, and initialization vector, and based on subscriber-related information. The authorization server does not share the private decryption key or initialization vector with the application server. If validated, the authorization server communicates validation-related information, including a permitted portion of subscriber-related information, to the application server.

In one embodiment, a method is provided that comprises determining, by a first device operatively coupled to a processor, an aggregation level for application by a second device to decode candidate downlink control channels associated with a CORESET. The method further comprises transmitting, by the first device, aggregation level information to the second device indicating the aggregation level. As a result of the transmitting, the second device becomes configured to apply the aggregation level in association with attempting to decode the candidate control downlink control channels. In various embodiments, the aggregation level is determined based one or more criteria, including an aggregation level capability of the second device, a location of the second device relative to the first device, and a geometry associated with the second device.

  • Patent number: 12267232
    Abstract: Unlike smart devices, Internet of things (IoTs), such as meter readers, generate very low revenue per user. Traditional tunnel/bearer based connection-oriented architectures do not scale economically for billions of IoT devices due to the amount of signaling overhead associated with GTP tunnel setup/tear down and the states related to GTP tunnels maintained at various parts of the mobile network. However, the mobility network can efficiently support massive stationary and/or mobile IoTs by reducing the amount of signaling overhead, the state of the IoTs kept in network, and simplifying the data plane when possible.
