    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: 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: Apparatuses and computer-readable storage media for handling timers for mobile terminated circuit-switched fallback (MT CSFB) calls. An apparatus for a user equipment (UE) includes processing circuitry operably coupled to a data storage device. The data storage device is configured to store a value of an extended service request for mobile terminated services (EXT-MT) timer. The value of the EXT-MT timer is less than a value of a guard timer of a Visitor Location Register (VLR). The processing circuitry is configured to start the EXT-MT timer and generate an extended service request message to be transmitted to a Mobility Management Entity (MME) responsive to a paging for an MT CSFB call, and attempt to select a radio access technology of a different type of network if the EXT-MT timer expires before the UE successfully performs inter system change and a circuit switched fallback cancellation request was not received from a subscriber.
