  • Publication number: 20250212075
    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: 12341804
    Abstract: A system for providing secure browsing via a transparent network proxy is disclosed. The system may receive, from a client, a request to access a resource. The request may include an identifier that may be utilized to locate the resource. Once the request is received, the system may determine if the resource is not trusted, such as if the identifier is determined to be unknown or suspicious. If the resource is determined to not be trusted by the system, the system may forward the request to a virtual machine manager that may select a browser virtual machine from a pool of browser virtual machines. After the browser virtual machine is selected, the browser virtual machine may stream a rendering of the resource to the client based on the request. The rendering of the resource may be provided in lieu of the actual resource.

  • Patent number: 12341594
    Abstract: The described technology is generally directed to over-the-air configuration and management of new radio smart repeaters. To facilitate data forwarding, a smart repeater is configured to generate a forwarding layer that is logically above a physical layer of a mobile termination function (corresponding to a repeater link) and a physical layer of distributed unit function of the repeater equipment (corresponding to an access link). Via the forwarding layer, when traffic is received from a parent node, the traffic is forwarded via the access link to user equipment, and when traffic is received from a user equipment, the traffic is forwarded via the access link to a parent node. A smart repeater control management function/interface manages control plane signaling and configurations for the mobile termination function and distributed unit function.

  • Publication number: 20250202807
    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.

  • Publication number: 20250203470
    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.
