    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: A wireless relay serves User Equipment (UE) with a media service that uses a Quality-of-Service (QoS) level. In the wireless relay, Relay Equipment (RE) wirelessly receives a network bearer configuration message indicating the QoS level for the UE and responsively configures a wireless network bearer to use the QoS level for the UE. A relay eNodeB wirelessly transfers an access bearer configuration message to the UE indicating the QoS level and configures a wireless access bearer to use the QoS level for the UE. The relay eNodeB wirelessly exchanges media with the UE over the wireless access bearer using the QoS level. The RE wirelessly exchanges the media with a wireless base station over the wireless network bearer using the QoS level.

    Abstract: A wireless relay serves a first User Equipment (UE). An eNodeB wirelessly exchanges UE signaling data and UE user data with the first UE. The eNodeB processes the UE signaling data to generate S1-MME signaling data and exchanges the S1-MME signaling data with an Ethernet switch in the relay. The 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 Ethernet switch. The Ethernet switch exchanges the non-GTP user data over a Wide Area Network (WAN) with a Secure Gateway (Se-GW) to a core Long Term Evolution (LTE) network.

    Abstract: A wireless User Equipment (UE) associates video session capabilities with relay identifiers. The UE wirelessly establishes a video session using a network address. The UE receives a handover command and wirelessly attaches to a wireless relay. The UE receives a new network address and a relay identifier that identifies the wireless relay from the wireless relay. The UE determines if the wireless relay supports the video session mobility based on the received relay identifier and the association of the video session capabilities with the relay identifiers. The UE continues the video session using the initial network address when the wireless relay supports the video session mobility. The UE re-establishes the video session using the new network address when the wireless relay does not support the video session mobility.

    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: In a wireless network, a Distributed Unit (DU) receives Uplink (UL) data from User Equipment (UE) and a Central Unit (CU) receives Downlink (DL) data for the UE. When DL-centric applications in the UE use the DL, the CU executes most network applications and the DU executes a few network applications. When the DL-centric applications use the UL, the DU executes the network applications and the CU transfers the UL data to the core. When UL-centric applications in the UE use the DL, the CU routes the DL data to the DU, and the DU executes the network applications. When the UL-centric applications use the UL, the DU executes a few network applications and the CU executes most network applications to route the data to the core. Advantageously, the DU and the CU are optimized to process UL/DL data for a user application based on whether the user application is UL-centric or DL-centric.

    Abstract: A wireless relay receives user data from User Equipment (UE). In the wireless relay, a Proxy Mobile Internet Protocol (PMIP) Media Access Gateway (MAG) compresses the user data and transfers a PMIP packet having a packet header and the compressed user data. In the wireless relay, relay equipment compresses the packet header and wirelessly transmits the PMIP packet. A wireless network node wirelessly receives the PMIP packet, decompresses the packet header, and transfers the PMIP packet to a network gateway. In the network gateway, a PMIP Local Mobility Anchor (LMA) receives the PMIP packet, decompresses the user data, and transfers the user data.

    Abstract: In a wireless relay, an eNodeB exchanges user data between User Equipment (UE) and a Local Gateway (L-GW). The L-GW separates the user data into Radio Area Network (RAN) user data and Wide Area Network (WAN) user data. The L-GW performs Tunneling Compression Multiplexing (TCM) on the RAN and WAN user data. The L-GW exchanges the compressed RAN and WAN user data with a data switch. The data switch exchanges the compressed RAN user data with Relay Equipment (RE) and exchanges the compressed WAN user data with an Internet Protocol Security (IPSec) agent. The RE performs Robust Header Compression (ROHC) over Long Term Evolution for a RAN data tunnel and wirelessly exchanges the compressed RAN user data over the compressed RAN data tunnel. The IPSec agent performs ROHCoIPSec for a WAN data tunnel and exchanges the compressed WAN user data over the compressed WAN data tunnel.
