Abstract: Techniques to determine location-related data for a plurality of access points located in an area in communication with a network by determining that a plurality of access points in a network are associated with a same geographical area including identifying, from among the plurality of access points, a first access point associated with the geographical area, determining first location-related data for the first access point, determining second location-related data for a second access point, the second access point being interior to the first access point within the network based at least in part on a determination that the second access point has at least a threshold number of the neighbor access points, and exchanging ranging data indicative of a first relative distance between the first access point and the second access point, the ranging data based at least in part on ranging message exchange measurements.

Abstract: Connection issue prediction may be provided. A computing device may receive first Channel State Information (CSI) for a first link associated with a client device. The first CSI may be collected when beamforming was trained on a second link associated with the client device. Second CSI may be received for the first link associated with the client device. The second CSI may be collected at a time subsequent to when beamforming was trained on the second link associated with the client device. A correlation between the first CSI and the second CSI may be determined to be below a predetermined threshold. A status of the beamforming performed on the second link associated with the client device may be set to stale in response to determining that the correlation between the first CSI and the second CSI is below the predetermined threshold.

Abstract: A method is provided for avoiding context transfers by a first Access and Mobility Management Function (AMF) connected to a first gNB to a second AMF when a user equipment (UE) in idle mode moves from the first gNB to a second gNB. The method may include provisioning the first AMF and the second AMF with the same tracking area identity (TAI), the first AMF and the second AMF s being connected to a respective enterprise gNB. The method may also include configuring the 5G packet core network comprising a session management function (SMF) in communications with the first AMF and the second AMF, to avoid transferring a UE context from the first AMF to the second AMF when the user equipment (UE) in the idle mode moves from a first AMF to the second AMF. The UE context remains with the first AMF.

Abstract: Presented herein are techniques for cropping video streams to create an optimized layout in which participants of a meeting are a similar size. A user device receives a plurality of video streams, each video stream including at least one face of a participant participating in a video communication session. Faces in one or more of the plurality of video streams are cropped so that faces in the plurality of video streams are approximately equal in size, to produce a plurality of processed video streams. The plurality of processed video streams are sorted according to video stream widths to produce sorted video streams and the plurality of sorted video streams are distributed for display across a smallest number of rows possible on a display of the user device.

Abstract: Techniques for authenticating and enforcing differentiated policies for a virtual machine (VM) executing in bridge mode on a wireless host device in a media access control (MAC)-based authentication network are described. In an example method a wireless host device is authorized to join a fabric enabled wireless network. A VM executes in bridge mode on the wireless host device. At the fabric edge, a source MAC address of the VM is determined. A session is created between the VM and an authentication server. The VM is authenticated. A policy for the VM is determined. A source internet protocol (IP) address is assigned to the VM to create a MAC-IP binding. A data-plane device in the fabric enabled wireless network is programmed to apply the policy to traffic communicated with the VM. Finally, the data-plane device applies the policy for the VM based at least in part on the MAC-IP binding.

Abstract: A method for communicating in a digital conversation is implemented on a computing device and includes: receiving an interactive contextual emoji from a first digital conversation participant to post in the digital conversation with at least a second digital conversation participant, where the interactive contextual emoji is pre-defined to indicate at least a current availability status associated with the first digital conversation participant, requesting the current availability status from a status application based on at least an indication of the interactive contextual emoji, where the status application maintains the current availability status, receiving the current availability status from the status application, and displaying the interactive contextual emoji in the digital conversation with at least an indication of the current availability status.

Abstract: Techniques for automatically providing per tenant weighted DCMP over shared transport interfaces and automated flow has load balancing are described. The techniques may include onboarding the tenant to the local multi-tenant edge device associated with a tenant, where the resource profile defines a traffic allowance per transport interface for the tenant. Local weight per transport interface is applied. Information including local weight per transport interface is transmitted to a remote device via an SD-WAN controller. Information including a remote weight per transport interface of the remote device is received via the SD-WAN controller. Traffic is routed from the tenant based on local weight per transport interface of the local device and remote weight per transport interface of the remote device.

Abstract: The automatic determination of components for Time Sensitive Networking (TSN), and more specifically the automatic determination of the Gate Duration (GD) and Guard Band (GB) for TSN may be provided. To determine the GB and/or GD for a TSN gate, a Time Error (TE) may be determined, and TSN components may be received. An Access Category (AC) and a per-AC Enhanced Distributed Channel Access (EDCA) state may be determined using the TID, wherein the per-AC EDCA includes a Contention Window (CW) minimum. Next, an Arbitration Interframe Space Number (AIFSN) of an upcoming data unit is determined using the using the AC and per-AC EDCA. The GB may be determined based on the AIFSN, the CW minimum, and the TE. The Gate Duration (GD) may be determined based on the TE and calculating a number of symbols in a MAC Protocol Data Unit (MPDU) and the upcoming data unit.

Abstract: Disclosed herein are systems, methods, and computer-readable media for applying differential charging over user plane for DCNR capable UEs. In one aspect, a method includes receiving a session request at a control plane gateway in association with a dual connectivity attachment request by a user equipment to connect to a network, sending a request for tunnel binding IDs to a Policy and Charging Rules Function (PCRF), wherein each of the tunnel binding IDs is associated with one of different types of network access for the user equipment, receiving the tunnel binding IDs from the PCRF, and programming a user plane with the tunnel binding IDs and corresponding charging rules for the different types of network access, the user equipment being charged for data usage using the charging rules and depending on which of the different types of network access is used by the user equipment to connect to the network.
