  • Patent number: 11864258
    Abstract: Recovering bearers after a service interruption of a relay node includes receiving, at a relay gateway, an instruction to modify bearers from a mobility management entity (MME), the instruction identifying one or more bearers that were in use by the relay node prior to the service interruption, identifying, at the relay gateway, at least one additional bearer in use prior to the service interruption not identified in the instruction received from the MME, and instructing the MME to create the at least one additional bearer. The at least one additional bearer can include a non-GBR bearer, such as a bearer with QCI of 1 used for VoLTE.

  • Patent number: 11553362
    Abstract: In a wireless communication relay, a network transceiver wirelessly detects wireless access points. The network transceiver beamforms wireless test signals and wirelessly transmits the beamformed wireless test signals to the wireless access points. A user transceiver in the relay wirelessly detects cross-relay interference levels when the network transceiver wirelessly transmits the beamformed wireless test signals to the wireless access points. The user transceiver transfers the cross-relay interference levels for the wireless access points to the network transceiver. The network transceiver selects one of the wireless access points based on the cross-relay interference levels for the wireless access points. The network transceiver wirelessly exchanges user data with the selected one of the wireless access points and exchanges the user data with the user transceiver.

  • Patent number: 11206560
    Abstract: A wireless relay mitigates cross-relay interference when serving wireless user devices. A network transceiver detects wireless access points and determines signal strengths for the wireless access points. The network transceiver transmits test signals to the wireless access points and directs a user transceiver to detect interference levels during the test. The network transceiver uses the interference level reported by user transceiver to calculate the interference level it would receive from the transmitter of user transceiver with a certain algorithm. The network transceiver selects wireless access points based on their signal strength and calculated cross-relay interference levels. The network transceiver exchanges user data with the selected wireless access points. The user transceiver exchanges the user data with the wireless user devices.

  • Publication number: 20210352562
    Abstract: A wireless communication relay tests data throughputs over a Fifth Generation New Radio (5GNR) network XCVR and a wireline network XCVR. The testing over the wireline network XCVR comprises a test of the data throughputs through a Local Break-Out (LBO) router or an N3 Interworking Function (N3IWF). The relay selects one of the 5GNR network XCVR and the wireline network XCVR based on the data throughput testing and indicates the selected network XCVR to a user XCVR. The user XCVR exchanges user data with the wireless UE and exchanges the user data with the selected one of the 5GNR network XCVR and the wireline network XCVR. The selected one of the 5GNR network XCVR and the wireline network XCVR exchanges the user data with one or more data communication networks.

  • Patent number: 11166230
    Abstract: Selecting a donor access node for a relay node based on a number of component carriers includes identifying one or more potential donor access nodes deploying one or more carriers, measuring a reference signal strength for each of the one or more potential donor access nodes, determining which of the one or more potential donor access nodes deploys a highest number of component carriers, and sending a request to attach to the potential donor access node deploying the highest number of component carriers and having a reference signal strength that meets a reference signal criteria.

  • Patent number: 11102699
    Abstract: A wireless communication relay wirelessly serves User Equipment (UEs) with wireless data services. Relay circuitry tests data throughputs over a Fifth Generation New Radio (5GNR) network Transceiver (XCVR), Long Term Evolution (LTE) network XCVR, and wireline network XCVR. The relay circuitry selects sets of network XCVRs for the user XCVRs based on the data throughput testing. The relay circuitry indicates the selected network XCVRs to the user XCVRs. The user XCVRs wirelessly exchange user data with the wireless UEs and exchange the user data with the selected network XCVRs. The selected network XCVRs exchange the user data with one or more data communication networks.

  • Patent number: 10939341
    Abstract: Systems, methods, and processing nodes for selecting a donor access node for a relay node comprising a plurality of directional antennae include instructing the relay node to attach to a first preferred donor access node using a first antenna of the plurality of directional antennae. While maintaining the connection with the first preferred donor access node using the first antenna, the relay node can scan for potential donor access nodes using one or more remaining antennae of the plurality of directional antennae and, upon identifying a second preferred donor access node from the potential donor access nodes, to perform a handover from the first preferred donor access node to the second preferred donor access node.

  • Patent number: 10805874
    Abstract: A wireless data relay has radio circuitry to wirelessly scan a frequency band having frequency channels. The radio circuitry attaches to a wireless network over the frequency band. The radio circuitry receives signaling from the wireless network indicating allowed frequency channels and transfers the signaling to control circuitry. In the wireless data relay, the control circuitry processes the signaling to direct the radio circuitry to use the allowed frequency channels instead of the frequency band. In response, the radio circuitry wirelessly scans the allowed frequency channels instead of the frequency band. The radio circuitry wirelessly re-attaches to the wireless communication network over the allowed frequency channels. The radio circuitry exchanges user data with the UEs. The radio circuitry exchanges the user data with the wireless network over the allowed frequency channels.
