  • Patent number: 10993169
    Abstract: Methods and systems are described for intelligently steering client devices operating in an enterprise network system to an appropriate access point based on types of traffic on each client device and/or types of traffic on access points. In particular, client devices may be moved to a different access point when the wireless channel provided by a current access point fails to meet the signal strength requirements of latency sensitive traffic utilized by the client device. Client devices may be further steered to new access points based on load conditions on access points. For example, client devices with low priority traffic sessions may be steered away from access points with high traffic load levels. Accordingly, the methods and systems described herein ensure improved network access for latency sensitive access categories and/or access categories that are considered important to an enterprise system with minimal disruptions to these sessions.

  • Patent number: 10932176
    Abstract: In a wireless access node, a baseband unit (BBU) detects a fault and responsively directs an Integrated Access and Backhaul (IAB) Mobile Terminal (MT) to scan for a wireless IAB service. The IAB MT scans for the wireless IAB service and establishes a wireless IAB link. The BBU exchanges fault data with the IAB MT. The IAB MT wirelessly exchanges the fault data with a neighbor access node over the wireless IAB link. The BBU recovers from the fault in response to the fault data.

  • Patent number: 10932168
    Abstract: Embodiments of a Next Generation Node-B (gNB) and methods of communication are disclosed herein. The gNB may be configurable to operate as a source gNB (S-gNB). The S-gNB may transfer, from a control plane (CU-CP) of the S-gNB to a CU-CP of a target gNB (T-gNB), an XnAP handover request message that indicates an Xn handover of a User Equipment (UE) from the S-gNB to the T-gNB. The S-gNB may initiate data forwarding, from a user plane (CU-UP) of the S-gNB to a CU-UP of the T-gNB, of downlink data packets. The data forwarding may be terminated based on reception of end marker packets from a user plane function (UPF) entity. The CU-UP of the S-gNB may transfer end marker packets to the CU-UP of the S-gNB to indicate termination of the data forwarding.

  • Patent number: 10917821
    Abstract: Embodiments can provide an inter-cell handover method and a controller to shorten a handover delay. For achieving such, a target cell can be determined by a first controller of a source cell. The first controller can send a pre-handover request to a second controller, which may be a controller of the target cell. The pre-handover request can be configured for instructing the second controller to allocate a first resource for a cell handover to a terminal device. The first controller can send a handover command to the terminal device when the first controller determines that the terminal device meets a handover condition. The handover command can be configured for instructing the terminal device to be handed over from the source cell to the target cell based on the first resource.
