Abstract: Central Unit (CU) circuitry in a wireless data network serves wireless User Equipment (UE) with an integrated Packet Data Convergence Protocol (PDCP). The CU circuitry receives downlink data from a Fifth Generation New Radio (5GNR) Service Data Adaption Protocol (SDAP) component. The CU circuitry executes the integrated PDCP to route the downlink data from the 5GNR SDAP component to an Institute of Electrical and Electronic Engineers 802.11 (WIFI) Radio Link Control (RLC) component. The CU circuitry receives uplink data from the WIFI RLC component. The CU circuitry executes the integrated PDCP to route the uplink data from the WIFI RLC receive memory to the 5 GNR SDAP component.

Abstract: A wireless relay serves User Equipment (UE) over a wireless Proxy Mobile Internet Protocol (PMIP) tunnel and a wireline PMIP tunnel to a Local Mobility Anchor (LMA). The wireless relay receives a wireless network address, a wireline network address, and an LMA network address. The wireless relay receives a request for a UE bearer and selects the wireless network or the wireline network. A Media Access Gateway (MAG) in the wireless relay transfers a PMIP update to the LMA that indicates the wireless network address or wireline network address based on the selected network. The wireless relay wirelessly exchanges user data with the UE. The MAG exchanges the user data with the LMA over the wireless PMIP tunnel or the wireline PMIP tunnel based on the selected network.

Abstract: In a data communication network, a wireless relay exchanges signaling data with User Equipment (UEs). The wireless relay compresses/decompresses Long Term Evolution (LTE) S1-MME signaling data and wirelessly exchanges the compressed the LTE S1-MME signaling data with an eNodeB. The eNodeB wirelessly exchanges the compressed LTE S1-MME signaling data with the wireless relay. The eNodeB compresses/decompresses the LTE S1-MME signaling data and exchanges the decompressed LTE S1-MME signaling data with the MME. The MME processes the decompressed LTE S1-MME signaling data to establish wireless data bearers for the UEs through the wireless relay to the eNodeB. The wireless relay wirelessly exchanges user data with the UEs, compresses/decompresses the user data, and wirelessly exchanges the compressed user data with the eNodeB. The eNodeB wirelessly exchanges the compressed UE user data with the wireless relay, compresses/decompresses the user data, and exchanges the decompressed user data.

Abstract: A wireless relay serves a first User Equipment (UE). A first eNodeB in the relay wirelessly exchanges UE signaling data and UE user data with the first UE. The first eNodeB processes the UE signaling data to generate S1-MME signaling data and exchanges the S1-MME signaling data with a second UE in the relay. The first eNodeB processes the UE user data to generate S1-U user data and exchanges the S1-U user data with a Local Serving Gateway (L-SGW) in the relay. The L-SGW terminates the S1-U user data to generate non-General Packet Radio Service Transfer Protocol (non-GTP) user data. The L-SGW exchanges the non-GTP user data with the second UE in the relay. The second UE compresses/decompresses the non-GTP user data and the S1-MME signaling data. The second UE wirelessly exchanges the compressed non-GTP user data the compressed S1-MME signaling data with a second eNodeB.

Abstract: A wireless relay controls backhaul in a data communication network. Relay user equipment attaches to a wireless base station coupled to a data network core and receives a first backhaul connection. An Ethernet switch attaches to a network gateway coupled to the data network core and establishes a second backhaul connection. The relay base station receives status data for the first backhaul connection through the wireless base station. The relay base station exchanges wireless user data with served user equipment. The relay base station selects one of the backhaul connections for the user data based on the status data of the first backhaul connection and exchanges the user data with the data network core over the selected one of the backhaul connections. The relay base station may receive and use status data for the second backhaul connection or the user data media type to select backhaul connections.
