Abstract: Embodiments of a ProSe Direct Discovery process are described. In some embodiments, an apparatus of a user equipment (UE) is configured as a Proximity Services (ProSe) enabled UE, and may encode, for transmission over a PC3 interface to a ProSe Function in a Home Public Land Mobile Network (HPLMN), a discovery request message for an announcing procedure, including transmission of one or more announcements over a PC5 interface, wherein the discovery request message for the announcing procedure includes a PC5 technology (PC5_tech) parameter to indicate a PC5 radio technology to be used by the UE for the announcing procedure. In some embodiments, the UE may decode a discovery response message for the announcing procedure, received over the PC3 interface from the ProSe Function in the HPLMN, including a ProSe application code and the PC5_tech parameter to indicate the PC5 radio technology authorized to be used for the ProSe application code.

Abstract: Embodiments of a UE and methods for D2D communication are generally described herein. The UE may transmit, as part of an in-network communication session, a D2D discovery status message. The D2D discovery status message may indicate an initiation or termination of a D2D discovery operation at the UE and may indicate if the UE is announcing or monitoring part of the D2D discovery operation. The D2D discovery operation may be at least partly for configuring a D2D communication session between the UE and one or more other UEs. The UE may transmit, as part of the D2D discovery operation, a D2D discovery signal for reception at one or more other UEs. The UE may transmit and receive D2D packets over a direct link to a second UE as part of the D2D communication session.

Abstract translation: 本文中通常描述UE的实施例和用于D2D通信的方法。 作为网络内通信会话的一部分，UE可以发送D2D发现状态消息。 D2D发现状态消息可以指示在UE处的D2D发现操作的启动或终止，并且可以指示UE是否通知或监视部分D2D发现操作。 D2D发现操作可以至少部分地用于在UE和一个或多个其他UE之间配置D2D通信会话。 作为D2D发现操作的一部分，UE可以发送用于在一个或多个其他UE处接收的D2D发现信号。 作为D2D通信会话的一部分，UE可以通过作为第二UE的直接链路来发送和接收D2D分组。

Abstract: This disclosure describes systems, methods, and devices related to data forwarding tunnel establishment between two user plane functions in fifth generation (5G). A device may determine an association of an access and mobility management function (AMF) with a first radio access network (RAN). The device may identify a handover request message received from the first RAN via the AMF. The device may identify a request to establish an indirect data forwarding associated with the handover, wherein the request is received from the first RAN via the AMF. The device may cause to send a response addressed to the AMF indicating that the indirect data forwarding is established.

Abstract: Devices, methods, user equipment (UE), base stations, storage media, and other embodiments are provided for managing associations in a communication network. In one example embodiment, a Next Generation (NG) core network device is configured for an Access and Mobility Management Function (AMF) with an NG-Radio Access Network (NG-RAN) node. The network device may be configured to access a plurality of Transport Network Link (TNL) associations and generate an AMF configuration update using the TNL associations, the AMF configuration update comprising AMF transport layer address information for the plurality of TNL associations. The network device may then initiate transmission of the AMF configuration update comprising the AMF transport layer address information to the NG-RAN node. Additional embodiments may involve binding updates or setup response messaging for managing associations, along with additional operations.

Abstract: Systems and methods of providing 5G access for a UE are generally described. The UE is simultaneously connected via dual radio operation to a legacy and 5G access system. The UE mobility management states for the access systems are independent of each other. The EPC and 5G CN share an HSS and may share a IP anchor. When handover occurs between access systems, the IP address is retained and the IP anchor used when the UE transmits an Attach Request having a Handover Attach Request Type and otherwise a new IP address is provided and the HSS but not the IP anchor is common between the access systems. The 5G eNB to which the UE is connected is standalone and connected to the 5G CN or dual mode and connected with an EPC via an LTE anchor in addition to the 5G CN.

Abstract: Router advertisements may be used to configure multi-homed Protocol Data Unit (PDU) sessions. A first router advertisement message from a first PDU session anchor and a second router advertisement message from a second PDU session anchor may be decoded. A user equipment (UE) may identify, based on the first and second router advertisement messages, a first preference value associated with destination routes of the first network and a second preference value associated with destination routes of the second data network. The UE may determine a destination data network for a signal by comparing a destination route of the signal to destination routes associated with whichever data network has a greater preference value. The UE may prepare the signal with a prefix based on the destination data network.

Abstract: User equipment (UEs) can fallback to a legacy system, such as an evolved packet system (EPS), from a fifth generation system (5GS). For example, a UE camps on the 5GS network by default. When an indicator of a voice call is detected, the UE performs a fallback to EPS for a duration of the voice call. After the voice call, the UE can return to the 5GS. In another example, the UE detects an emergency session request (e.g., internet protocol multimedia subsystem (IMS) emergency session request). The UE performs a fallback to EPS for a duration of the emergency session. After the emergency session is complete, the UE can return to the 5GS. The solution can operate with UEs that operate in either Single Registration (SR) mode embodiments or Dual Registration (DR) mode embodiments. Depending on the embodiment, the UE can perform a handover or redirection to the legacy system (such as E-UTRAN).

Abstract: Embodiments of an Evolved Node-B (eNB), User Equipment (UE) and methods for communication are generally described herein. The eNB may receive, from a mobility management entity (MME), a path switch trigger message that indicates an identifier of an eRelay UE for a relay arrangement for an eRemote UE. The eNB may determine whether the eRelay UE is served by the eNB. The eNB may, if it is determined that the eRelay UE is served by the eNB, transmit a radio resource control (RRC) connection reconfiguration message to the eRemote UE. The RRC connection reconfiguration message may indicate a switch from a direct communication to an indirect communication between the eRemote UE and the eNB. The indirect communication may be through the eRelay UE in accordance with the relay arrangement.
