Abstract: Techniques are provided for managing the provisioning of voice services to a user equipment (UE) in a fifth generation (5G) network. For example, the UE generates a registration request message that includes 5G mobility management (5GMM) capabilities of the UE that are indicative of whether the UE supports voice over internet protocol multimedia subsystem (IMS), and transmits the registration request message to a next generation radio acess network (NGRAN) node in the 5G wireless network. Based on the 5GMM capabilities, the NG-RAN node can determine whether voice over IMS can be provided to UE by comparing the 5GMM capabilities to capabilities of the NG-RAN node.

Abstract: An apparatus of user equipment (UE) comprises one or more baseband processors to process at least one non-public network (NPN) identifier (NPN-ID) broadcast by an NPN and zero or more Public Land Mobile Network (PLMN) identifier (PLMN-ID) broadcast by a PLMN, to compare the NPN-ID against a logical list of NPN-IDs and PLMN-IDs ranked in decreasing order of priority, and to connect with the highest ranked processed NPN or PLMN based on a rank of the NPN-ID in the list. The apparatus can include a memory to store the list of NPN-IDs and PLMN-IDs as a logical list of Equivalent Home Networks or as Operator Controlled Network Selector with Access Technology list.

Abstract: Methods, systems, and storage media are described for the utilization of user equipment (UE) identifiers for registration in fifth generation (5G) systems. An apparatus of a user equipment includes processing circuitry to: retrieve a first 5G-GUTI from a memory; generate a registration request message that includes the first 5G-GUTI; encode the registration request message for transmission to a fifth-generation core (5GC) network of a second PLMN; receive a registration accept message that includes a second 5G-GUTI; and access the second PLMN using the second 5G-GUTI.

Abstract: Techniques are provided for managing the provisioning of voice services to a user equipment (UE) in a fifth generation (5G) network by a base station (BS). For example, the BS receives an initial registration request message that includes 5G mobility management (5GMM) capabilities of the UE that are indicative of whether the UE supports voice over internet protocol multimedia subsystem (IMS), and compares the 5GMM capabilities of the UE and the capabilities of the BS. Based on the comparison, the BS can transmit a registration accept message including an indication of whether voice over IMS is approved.

Abstract: An edge computing component is configured to receive application specific user information for a first application client (AC) user from a first user equipment (UE) with a first AC, receive application specific user information for a second AC user from a second UE with a second AC, identify a condition related to a location of the first AC relative to one or more service areas related to edge computing and transmit a notification to the second UE, the notification indicating a presence of the first AC user relative to the one or more service areas.

Abstract: Systems and methods of protecting an initial NAS message are described. Depending on whether a security contex.1: for a serving PLMN is stored, the UE uses either a public key from the serving PLMN or a key from the security context to encrypt parts of the initial NAS message. An initial NAS message containing the encrypted parts is then sent to an AMF of the serving PLMN. The serving PLMN public key is transmitted via a SIB. Prior to transmission of the initial NAS message or in parallel with it, an RRC message is sent to the base station. The RRC message contains the UE identifier and/or a NSSAI encrypted using the serving PLMN public key.

Abstract: Embodiments are disclosed for application function (AF) initiated multicast session join procedures for multicast broadcast services (MBS), where a user equipment (UE) initiates the session leaving procedure. An AF server can receive a request from the UE to fetch content, and determine that the content is provided by the AF server via a multicast session of a MBS. The AF server can transmit another request to a core network (e.g., a next generation core network) to enable the UE to join the multicast session of the MBS. If the UE does not already have a protocol data unit (PDU) session to a Data Network Name/Single Network Slice Selection Assistance Information (DNN/S-NSSAI) providing the multicast session of the MBS, the AF server can invoke application triggering and/or application level redirection to enable the UE to access an AF instance on the DNN/S-NSSAI providing the multicast session of the MBS.

Abstract: Some embodiments include an apparatus, method, and computer program product for public land mobile network (PLMN) selection for disaster roaming in a 5G wireless communications system. A user equipment (UE) can receive two or more messages that disaster roaming service is offered by two or more forbidden public land mobile networks (PLMNs) of a forbidden PLMN list of the UE. The UE can select a first forbidden PLMN of the two or more forbidden PLMNs, where the first forbidden PLMN corresponds to a highest priority PLMN of a preferred PLMN list of the UE, and establish communications, via the transceiver, with the first forbidden PLMN. Some embodiments include designating a forbidden PLMN as offering a disaster roaming PLMN for manual selection. Some embodiments include enabling a Closed Access Group (CAG)-capable UE to access disaster roaming services from a forbidden PLMN of a CAG-only cell or a 5G cell.

Abstract: An apparatus of an Access and Mobility Function (AMF) comprises one or more baseband processors to process a request from a new AMF for a user equipment (UE) context transfer for a UE registered to the AMF via a first access type, wherein UE context transfer request includes an indication of a second access type for the UE to register with the new AMF, and to determine whether an entire UE context should be returned to the new AMF based on the second access type. The apparatus can include a memory to store the request.
