Abstract: Some embodiments of this disclosure include apparatuses and methods for managing a fast return of a user equipment (UE) to 5G systems (5GS) after handover to Evolved Packet System (EPS) due to EPS fallback from 5GS. The method can include at least generating a handover request including an indication indicating a handover reason of no presence of quality of service (QoS) flow for a voice signal to the UE; receiving a handover command generated by an access and mobility management function (AMF) to transfer the UE from the 5GS to the EPS based on the handover request; transmitting the handover command to the UE for the UE to establish a connection with the EPS; and after the flow of the voice signal has terminated, reestablishing a connection with the UE to reconnect the UE to the 5GS, wherein the connection with the BS is re-established based on a target ID of the BS.

Abstract: An apparatus used in a UE includes processing circuitry and memory. To configure the UE for a DNS resolution, the processing circuitry is to encode UL data for transmission to a first EAS via a first data path. The first data path includes a first UL CL UPF and a first PSA. A NAS SM message received from an SMF node is decoded. The NAS SM message includes an EAS rediscovery indication and a list of FQDNs associated with the first EAS. A DNS resolution procedure with a DNS server is performed in response to the EAS rediscovery indication, to obtain an IP address of a second EAS. The DNS resolution procedure is based on the list of FQDNs, and a second data path to the second EAS is established based on the IP address.

Abstract: An approach is described for a method for a fifth generation (5G) wireless communication or a new radio (NR) system that includes the following steps. The method includes receiving, by a source device from a UE, a registration request message indicating the UE is capable of a vehicle-to-everything (V2X) communication. The method further includes determining, by the source device, the UE is authorized for a V2X service, wherein the V2X service comprises the V2X communication. The method further includes transmitting, by the source device to the UE, a registration accept message based on determining the UE is authorized for the V2X service.

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: Systems, apparatuses, methods, and computer-readable media are provided for indicating local area data network (LADN) data network names (DNNs). In embodiments, a user equipment (UE) provides a list of configured LADN DNNs in a registration request message during a registration procedure. An Access and Mobility Management Function (AMF) determines LADN information for the UE by looking into configured LADN DNNs in the AMF and/or retrieved LADN authorization/subscription information. The LADN information includes a list of LADN DNNs and corresponding LADN service area(s) that the UE can use, including LADN DNNs that the UE can use in a current registration area. The AMF sends the LADN information to the UE in a registration accept message. Other embodiments may be described and/or claimed.

Abstract: Embodiments of a User Equipment (UE), an Evolved Node-B (eNB) and methods for communication are generally described herein. An UE may be configurable to operate as an eRelay UE. The eRelay UE may be configured to operate as a relay between an eNB and an eRemote UE. The eRelay UE may receive, from the eRemote UE, a message that includes an identifier of the eRemote UE for paging of the eRemote UE. The eRelay UE may determine whether a first paging message from the eNB includes the identifier of the eRemote UE. If it is determined that the first paging message includes the identifier of the eRemote UE, the eRelay UE may transmit, to the eRemote UE, a second paging message to page the eRemote UE. The second paging message includes the identifier of the eRemote UE.
