  • Publication number: 20250150900
    Abstract: Adaptable resiliency for a virtualized radio access network (vRAN) framework is disclosed. A resiliency management component can determine vRAN topological adaptations that can reflect resiliency requirements of service instance(s). Accordingly, sufficient redundant vRAN components to satisfy the resiliency requirements can be deployed. However, unlike conventional redundancy techniques that can determine a highest level of redundancy and then apply that relative to all supported services, the disclosed subject matter can avoid over-deploying redundant vRAN components, e.g., redundant components exceeding the resiliency requirement of a service instance, resulting in lowered monetary and non-monetary costs to maintain a vRAN. Moreover, as the services change, the topology of the vRAN can be automatically adapted to purge excessive redundancies, add newly required redundancies, etc., which can facilitate propagating an adequate but lean vRAN topology that is sufficiently resilient.

  • Patent number: 12292743
    Abstract: Aspects of the subject disclosure may include, for example, a method in which a processing system determines that performance of a service is required at a first location in a smart community; identifies a robot to be transported, and determines whether physical transport or virtual transport is to be performed for the robot. If physical transport is to be performed, the system initiates communication with a robot transport controller to schedule the physical transport to the first location from a different second location. If virtual transport is to be performed, the processing system initiates communication with a radio access network (RAN) to schedule the virtual transport; the virtual transport includes configuring the robot at the first location. Other embodiments are disclosed.

  • 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: 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.

  • Patent number: 12219449
    Abstract: In a 6G network, microservices can be utilized in the absence of a core network. For example, after a mobile device has authenticated, through its carrier network, with a transport service layer, microservices can be allocated to the mobile device without having to be transmitted via the core network. Thus, removing the core network from the process can generate a direct line of microservices from the transport layer to the end-user. Furthermore, additional microservices and/or resources can be access through a microservices library. Consequently, packets can be securely transmitted be a wireless network facilitating sending packet profile data from one to many node devices in anticipation of the packet traversing the various node devices.

  • Patent number: 12213034
    Abstract: Described is intelligent security based on the detection of the presence of mobile devices within a defined region, determined via accurate mobile device location sensing, e.g., within on the order of one meter. Upon detection of the presence of a mobile device within a defined region via mobile device millimeter wave-based position sensing, an identity associated with the mobile device is obtained. If the identity associated with the mobile device is not a trusted identity, action can be taken based on the presence of the identity within the defined region. The intelligent security can be implemented within an application program of a registered user's mobile device and/or a security system, such as a commercially available security system with alarm monitoring services. Various criteria can determine the action(s) to take, including by which region (if more than one), time of day, identity trust level, duration of presence, and the like.

  • Publication number: 20240373449
    Abstract: A framework for dynamic network resource allocation and energy saving based on the real-time environment, radio network information, and machine learning (ML) can be utilized via a radio access network (RAN) intelligent controller (RIC). Real-time and predicted network utilization can facilitate resource and energy savings by leveraging the RIC platform. For example, a network information base (NIB) in the RIC platform can collects RAN and user equipment (UE) resource related information in real time and provides the abstraction of the access network in the real time. ML can predict real-time information about the UEs at time t based on data analytics and real time radio resource needs. The RIC can then instruct the network to reduce or increase resources.
