Abstract: According to one configuration, a system includes user equipment in communication with a wireless base station. The user equipment receives a notification from a first wireless access point of multiple wireless access points. The notification indicates a set of candidate wireless access points in the wireless network environment in which to selectively perform a handoff from a first wireless access point. The user equipment monitors for occurrence of a trigger condition. In response to detecting a trigger condition, the user equipment identifies (such as selects) a second wireless access point (from the set of candidate wireless access points) in which to perform the handoff. Via communications from the user equipment to the second wireless access point, the user equipment initiates the handoff. The user equipment notifies the first wireless access point of the attempted and/or failed attempt of the handoff to the second wireless access point.

Abstract: A communications system includes content distribution hardware operable to detect presence of a window in a video stream in which to insert an advertisement. Multiple viewers receive and view the video stream. Advertisement management hardware in the communications system receives notification of the window as well as attributes of the viewers receiving the video stream.

The content distribution hardware inserts the selected advertisement in the window for distribution to the multiple viewers. During distribution of the advertisement in the window, if desired, the content distribution hardware monitors further use of the multiple communication devices to detect if any of the communication devices discontinue receiving the video stream during the window of time.

Abstract: A wireless communication system serves UEs over a 5GNR access point and a non-5GNR access point. The wireless base station transfers an attachment message for a UE to a network controller. The network controller transfers network signaling for the UE to the data network element responsive to the attachment message. The data network element transfers user data for the UE. The wireless base station transfers another attachment message that indicates a 5GNR attachment for another UE to the network controller. The network controller transfers other network signaling indicating the 5GNR attachment for the other UE to the data network element responsive to the other attachment message indicating the 5GNR attachment. The data network element transfers other user data for the other UE and monitors quality-of-service for the transfer of the other user data responsive to the 5GNR attachment indication in the other network signaling.

Abstract: Location access units (LAUs) in a wireless communications system (WCS) for transmitting information to a wireless client device in a WCS for determining location of wireless client device. The LAUs each include a transmitter(s) configured to transmit local wireless communications signal that includes identification information of the LAU, to a wireless client device in the WCS.

In one example, the carrier of a communication session with a client device in the WCS can instruct the client device to scan for local wireless communications signals transmitted by an LAU. The client device returns received identification information from received wireless communications signals transmitted by an LAU to the carrier to associate this location of the LAU to the client device.
