摘要： A wireless communication system (100) beamforms an uplink from an airborne transceiver (113, 114, 614, 1014, 1114, 1214) to a terrestrial transceiver (131, 132, 631). The airborne transceiver comprises antennas that have an antenna type an aperture beamwidth. The airborne transceiver transfers a transceiver ID to the terrestrial transceiver. The terrestrial transceiver initiates aerial uplink beamforming for the antenna type and the aperture beamwidth based on the airborne transceiver ID. The terrestrial transceiver determines uplink beamforming metrics and altitude for the airborne transmitter. The terrestrial transceiver generates an uplink beamforming instruction and an uplink power instruction for the antenna type and the aperture beamwidth of the airborne transceiver based on the uplink beamforming metrics and altitude. The terrestrial transceiver transfers the uplink beamforming instruction and the uplink power instruction to the airborne transceiver. The airborne transceiver beamforms, amplifies, and transmits an uplink wireless signal to the terrestrial transceiver per the uplink beamforming instruction and the uplink power instruction.

摘要： A wireless communication network (100, 400) hands-over wireless User Equipment (UE) (101, 401) from a serving cell (111, 411) to a neighbor cell (112, 411). The serving cell wirelessly exchanges data with the wireless UE and determines uplink interference for a radio band. The serving cell wirelessly transfers an uplink interference offset to the wireless UE that indicates the uplink interference at the serving cell for the radio band (131). The wireless UE uses the uplink interference offset to trigger a handover request to the serving cell. The handover request indicates downlink signal strength at the wireless UE for the serving cell. The serving cell initiates a handover to a neighbor cell responsive to a combination of the downlink signal strength at the wireless UE and the uplink interference for the serving cell falling below a handover threshold. After the handover, the neighbor cell wirelessly exchanges data with the wireless UE over a different radio band (132).

摘要： In a wireless communication network (100, 1000), a Gateway Control Plane (GW-C) (140, 640, 641, 642, 940) receives a session request for a User Equipment (UE) (101, 102, 103, 601, 1001) from an Access Point (AP) (111, 112, 113, 611, 1011, 1012) that serves the UE. The GW-C transfers a DNS request having an AP ID and network data. A Domain Name System (DNS) (150, 650, 651) translates the AP ID and the network data into an AGW-U ID and an EGW-U ID for co-located GW-Us. The GW-C receives a DNS response and transfers GW control signals using the AGW-U ID and the EGW-U ID. The co-located AGW-U (121, 122, 123) and EGW-U (131, 132, 133) serve the UE responsive to the control signals. In some examples, the selected AGW-U and EGW-U are co-located at the network edge near the AP.

摘要： A wireless access node (110, 310, 610) serves wireless user devices (101, 301, 601, 602, 603) with different services over a common radio channel (130, 330, 630). The different services are supported by different wireless network slices (121, 122, 123, 124, 521, 522, 523, 524, 621, 622, 623). The wireless access node determines service subchannels (131, 132, 133, 134) in the radio channel based on location and time. The wireless access node schedules resource blocks from the subchannels for their corresponding services. If a subchannel for one service is full, then the wireless access node schedules the remaining data for the service in the unscheduled resource blocks of the other subchannels if any. The wireless access node wirelessly exchanges data for the services with the wireless user devices over the scheduled resource blocks in the subchannels of the radio channel. The wireless access node exchanges the data with the wireless network slices that support the services.

摘要： A Network Function Virtualization (NFV) Software-Defined Network (SDN) (100, 500, 600) communicates across network boundaries with other NFV SDNs to support a data communication service. An NFV orchestrator (111) transfers forwarding graphs for service, NFV, and SDN Network-to-Network Interfaces (NNIs) to an SDN controller (112). The SDN controller (112) converts the forwarding graphs into forwarding instructions and transfers the forwarding instructions for the service, NFV, and SDN NNIs to an NFV SDN switching system (113). The NFV orchestrator (111) uses the NFV NNI to transfer its forwarding graphs over the NFV SDN switching system (113) across the network boundary to another NFV orchestrator (121). The SDN controller (112) uses the SDN NNI to transfer its forwarding instructions over the NFV SDN switching system (113) across the network boundary to another SDN controller (122). The NFV SDN switching system (113) uses the service NNI to transfer user data across the network boundary to another NFV SDN switching system (123).

摘要： A wireless communication system (100, 400) controls Carrier Aggregation (CA) at a wireless relay (110, 410). A wireless access point (120, 420, 600) wirelessly receives user data and transfers a first portion of the user data to a wireless User Equipment (UE) (101, 401) using a UE CA configuration and a second portion of the user data to the wireless relay (110, 410) using a relay CA configuration, wherein the wireless relay (110, 410) wirelessly serves additional UEs (102, 402). The wireless access point (120, 420, 600) determines an amount of the transferred user data and translates the amount of the transferred user data into a new UE CA configuration and a new relay CA configuration. The wireless access point (120, 420, 600) wirelessly receives additional user data and transfers a first portion of the additional user data to the wireless UE (101, 401) using the new UE CA configuration and a second portion of the additional user data to the wireless relay (110, 410) using the new relay CA configuration.

摘要： A Network Function Virtualization (NFV) Software Defined Network (SDN) (100, 600, 700) maintains hardware trusted communications. A source trust controller (141, 142) and a target trust controller (141, 142) establish hardware trust with a trust server (150). The trust server (150) exchanges information with the source trust controller (141, 142) that indicates the hardware trust for a target vSW (131, 132). The source trust controller (141, 142) exchanges the information with the source vSW (131, 132) that indicates the hardware trust for the target vSW (131, 132). The source vSW (131, 132) receives a Virtual Data Unit (VDU) from the source VNF (121, 122) for delivery to the target VNF (121, 122) over the target vSW (131, 132), and before transfer, the source vSW (131, 132) verifies hardware trust of the target vSW (131, 132) based on the HT information. Responsive to the hardware trust verification, the source vSW (131, 132) transfers the VDU for the delivery to the target vSW (131, 132). The target vSW (131, 132) transfers the VDU to the target VNF (121, 122).

摘要： A Software-Defined Network (SDN) authorizes Application Programming Interface (API) calls from user SDN applications (111-113) to user SDN controllers (121-123). A user SDN application (111-113) transfers an embedded code to an authorization SDN controller (124). The authorization SDN controller (124) translates the embedded code into an SDN controller network address and an SDN application privilege data set. The authorization SDN controller (124) transfers the SDN controller network address to the user SDN application (111-113). The authorization SDN controller (124) transfers the SDN application privilege data set to the user SDN controller (121-123). The user SDN application (111-113) transfers an SDN API call to the user SDN controller (121-123) using the SDN controller network address. The user SDN controller (121-123) determines if the SDN API call is authorized by the SDN application privilege data set. The user SDN controller (121-123) services the API call if the SDN API call is authorized and inhibits an unauthorized API call.
