    Abstract: A user equipment (UE) transmits a registration request message to a first public land mobile network (PLMN), wherein the first PLMN is a roaming PLMN, receives a registration accept message from the first PLMN, determines that the registration accept message includes a manipulated steering of roaming (SoR) container or does not include a SoR container, wherein the SoR container is configured by a home PLMN (HPLMN) of the UE and transmitted to the first PLMN from the HPLMN, determines that the registration accept message includes an indication that the first PLMN does not support voice over packet switching (VoPS) and adds the first PLMN to a first list of PLMNs in which voice service is not possible in an N1 mode.

    Abstract: If a paging or notification message is received by a user equipment (UE) when a UE-initiated 5GMM specific procedure or service request procedure is ongoing, a UE may buffer the paging or notification message. To buffer the paging or notification message, the UE may remember the pending mobile terminated transaction and re-attempt the registration or request procedure with the access category 0 (=MT_acc), if the ongoing UE-initiated 5GMM specific procedure or service request procedure fails due to access barring. If a 5GMM specific procedure or service request procedure is received by the network when a MT transaction is ongoing (i.e. a paging message with the access type set to 3GPP access or notification message via non-3GPP access with the access type indicating 3GPP access) the network may complete the incoming MT transaction and may remember the pending mobile terminated transaction and continue it once the MO transaction is completed.

    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: A user equipment (UE) is configured to receive broadcast information from a cell of a public land mobile network (PLMN) including a parameter indicating support for disaster roaming, wherein the PLMN is a forbidden PLMN (FPLMN) for the UE, attempt a registration with the FPLMN by sending a registration request to the PLMN including a PLMN ID of a determined PLMN under disaster, receive a message including a cause code indicating the disaster roaming for the FPLMN is not allowed in a current tracking area (TA) of the cell for the determined PLMN under disaster, store a tracking area identifier (TAI) of the cell and prevent further registration attempts with the FPLMN for the determined PLMN under disaster when the UE is in the current TA.

    Abstract: A user equipment (UE) is configured to receive broadcast information from a public land mobile network (PLMN) including at least a PLMN identifier (ID), attempt a registration with the PLMN by sending a registration request to the PLMN, wherein the UE attempts the registration via a base station operated by the PLMN deployed in a non-terrestrial network (NTN) arrangement including a non-terrestrial component configured to provide services to the UE via a service link, receive a message including a cause code indicating the PLMN is not allowed to operate at a current UE location and further including a set of attributes indicating further conditions wherein the registration with the PLMN is not allowed and avoid further registration attempts with the PLMN when the further conditions are met.

    Abstract: Disclosed are methods, systems, and computer-readable medium to perform operations including: receiving a request message from a user equipment (UE) served by a non-terrestrial access node, where the non-terrestrial access node is broadcasting a plurality of tracking area codes (TACs), and where a first TAC is associated with a first tracking area (TA) that is forbidden for the UE; and sending, to a core network node, the plurality of TACs in at least one information element.

    Abstract: A user equipment (UE) that initiates a periodic update timer, wherein the UE is configured to perform a periodic registration update procedure in response to a periodic update timer expiry event, identifies that the periodic update timer has expired, wherein the periodic update timer expiry event occurs when the UE is out of coverage, selects a cell to camp on, wherein the cell is known to be in a non-allowed area and initiates the periodic registration update procedure in response to the periodic update timer expiry event, wherein the UE delays the periodic registration update procedure until the UE enters a fifth generation mobility management (5GMM) operating substate associated with camping on the cell that is known to be in the non-allowed area.
