    Abstract: Devices, systems and methods for transitioning a UE to a new application server in response to a mobility event comprising, at a source application server handler: receiving an application ID (AC-ID) associated with an application client for a user equipment (UE); receiving a mobility event notification including a UE ID of the UE and a target data network access identifier (DNAI) to indicate a target edge data network to which a transition of a data connection for the application client is to be performed; encoding an outgoing transition request for transmission to a source application server to indicate the transition of the data connection from the source application server; and encoding an incoming transition request for transmission to a target application server handler (ASH) of the target edge data network to indicate the transition of the data connection to the target edge data network.

    Abstract: Embodiments of a User Equipment (UE) and methods of communication are generally described herein. The UE may be configurable to operate as an initiating UE for a vehicle-to-everything (V2X) application that includes PCS communication between the initiating UE and a receiving UE. The initiating UE may receive, from a base station, control signaling that indicates a default PCS radio access technology (RAT) for the V2X service. The default PCS RAT may be either a Long Term Evolution (LTE) PCS RAT or a New Radio (NR) PCS RAT. Based on the default PCS RAT and/or PCS RATs supported by the initiating UE, the initiating UE may select either the LTE PCS RAT or the NR PCS RAT. The selected PCS RAT may be proposed, in a negotiation with the receiving UE, for the V2X service.

    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.
