  • Patent number: 11026110
    Abstract: A method performed by a wireless communications device for measurement reporting. The measurement reporting comprises reporting measurements associated with a first wireless communications network to a network node operating in a second wireless communications network. The first wireless communications network operates according to a first RAT, and the second wireless communications network operates according to a second RAT. The wireless communications device obtains (401), from the network node, an identifier of one or more radio access network nodes operating in the first wireless communications network. The obtained identifier restricts a mobility of the wireless communications device in the first wireless communications network to the one or more radio access network nodes identified by the identifier. The wireless communications device excludes (402) from measurement reporting to the network node at least one of the identified radio access network nodes.

  • Publication number: 20210153276
    Abstract: In some aspects, methods, apparatuses, and computer program products are provided for handling RLC failures in PDCP duplication where there are two logical channels on which a PDCP entity can send packets. In some aspects, the radio network node may determine a mapping between the primary and secondary logical channels and serving cells, and how this mapping can be configured for the wireless device. In some aspects, the wireless device may take different actions depending on which of a primary and a secondary logical channel, i.e. RLC entity, fails. In some aspects, the wireless device operating in PDCP duplication may notify the radio network node about the failure of a radio link supporting the secondary logical channel without triggering the RLF procedure.

  • Patent number: 10992998
    Abstract: The virtual broadcast system of the present invention optimizes the routing of digital content among nodes along overlay networks that are dynamically reconfigured based upon forecasts of frequently-changing congestion levels of component interconnections within an underlying network. In the context of delivering streaming video over the Internet to large numbers of concurrent users, the present invention makes efficient use of the limited capacity of congested ASN peering points by employing deep learning techniques to forecast congestion levels across those ASN peering points and, based on those forecasts, to optimize the routing of video content along dynamically reconfigured overlay networks. The virtual broadcast system handles unscheduled as well as scheduled events, streams live as well as pre-recorded events, and streams those events in real time with minimal delay in a highly scalable fashion that maintains a consistent QoE among large numbers of concurrent viewers.

  • Publication number: 20210092787
    Abstract: In one aspect, a wireless device (50) configured for multi-carrier operation in a wireless communication network performs (702) measurements on one or more cells and/or beams and/or carriers, while in idle mode or in an inactive state. The wireless device determines (704) information for assisting an establishment of multi-carrier operation, based on the measurements, and transmits (706) the information to the wireless communication network. A network node receives this information for the cells/PERFORM beams/carriers and selects, based on the received information, one or more cells/beams/carriers for multi-carrier operation with the wireless device. The network node establishes multi-carrier operation for the wireless device using the selected cells/beams/or carriers.

  • Publication number: 20210092690
    Abstract: A wireless device that indicates multiple power classes to a network node, a network node that uses the indicated multiple power classes, and related methods of operation for the wireless device and the network node are disclosed. The disclosed embodiments aim at an increase flexibility in setting different power classes in different communication scenarios while reducing signalling overhead for capability signalling for the wireless device. This is achieved by using at least one set of power classes defining at least two power classes of the wireless device. Each set of power classes applies to a transmission band (A, B, C) supported by the wireless device and each power class in each set of power classes applies to a specific operative condition of the wireless device.

  • Publication number: 20210055453
    Abstract: A system for generating short-, medium, long-range and specific area and effect weather or climate forecasts by training a cluster of Al to “understand” the physics that effects the weather and running the clusters on a decentralized computing system or network. Individual modules for specific knowledge of different climate-variability phenomena can be integrated and interrogated to calculate the forecast based on a consensus of future predictions based on a subset of the clusters. The selection criteria determining which modules are deemed to fit may be adjusted to optimize the use of observations in forecasting specific climate variables or geographic regions in order to develop forecasts tailored to particular applications.

  • Patent number: 10924919
    Abstract: A wireless communication device (12) served by a wireless wide area network (WWAN) base station supports per-bearer switching of bearer traffic between the WWAN and a wireless local area network (WLAN) in a manner transparent to the WLAN. The device in this regard establishes a secure tunnel (24) through the WLAN to a security gateway (22), based on the device receiving a message from the WWAN base station (18) to establish the secure tunnel (24). The device switches bearer traffic between the WWAN and the WLAN on a per bearer basis, with bearer traffic switched to the WLAN being transported through the secure tunnel (24) and over a connection (26) between the security gateway (22) and the WWAN base station (18).

  • Publication number: 20210031634
    Abstract: A multi-motor switching system and method for obtaining a global optimization of performance criteria that takes into account variables and conditions across an entire driving cycle. The controller of the system is adapted to conduct a global optimization in that it determines the most optimal distribution of motor loads over an entire trip or driving cycle, as opposed to sequentially determining the optimized solution for a given point of time and localized set of current condition. In one embodiment where the control system provides for global optimization, the controller receives trip information through a trip planning tool. The controller utilizes the trip information to generate a driving cycle and further incorporates this information into the optimization process performed by the controller to determine the optimal solution for the entire trip.
