    Abstract: The present application relates to small data transmission (SDT). In an example, SDT is available for transferring information between a UE and a network, where a NAS layer of the UE is in a 5GMM-CONNECTED mode with an RRC inactive indication and an AS layer of the UE is in an RRC_INACTIVE state. To do so, the UE can be pre-configured to classify the information as qualifying for SDT. In addition, resources can be pre-configured for the SDT. For instance, the UE can maintain a set of radio bearers in a suspended state. While the NAS layer is in the 5GMM-CONNECTED mode with the inactive indication and the AS layer is in the RRC_INACTIVE state, one or more of the pre-configured resources can be used to transmit the information between the UE and the network.

    Abstract: Systems and methods of providing steering of roaming (SOR) information in a 5G VPLMN are described. A UE receives a REGISTRATION ACCEPT message from an AMF of the VPLMN during initial or mobility registration of the UE in the VPLMN and DL NAS TRANSPORT message thereafter. The message has a Payload container information element (IE) set to secured packet. The SOR information indicates a list of preferred PLMN/access technology combinations, which is uploaded to a memory after a successful security check to verify that the list of preferred PLMN/access technology combinations is provided by the UDM of the HPLMN and is not tampered with by the VPLMN. When the message also contains a request for acknowledgment of successful security check of the list of preferred PLMN/access technology combinations, the UE transmits to the AMF the acknowledgment in a REGISTRATION COMPLETE or a DL NAS TRANSPORT message.

    Abstract: Systems and methods are provided for public land mobile network (PLMN) selection for disaster roaming. A user equipment (UE) determines a disaster condition at a first PLMN, where the UE is a subscriber of the first PLMN. The UE determines an availability of a second PLMN for disaster roaming. The UE selects the second PLMN and attempts registration on the second PLMN for disaster roaming. In response to attempting the registration on the second PLMN for disaster roaming, the UE receives a registration reject message including a cause value corresponding to a registration failure for disaster roaming on the second PLMN due to the disaster condition on the first PLMN. The UE waits for a first period of time before again attempting to register for disaster roaming on the second PLMN for the first PLMN with the disaster condition.

    CPC classification number: H04B7/18513

    Abstract: The present application relates to devices and components including apparatus, systems, and methods that support discontinuous network coverage. In an example, a UE and a network exchange information indicating a capability for using a control plane, a user plane, a short message service, and/or an operation and maintenance server for the transfer of coverage data of a non-terrestrial network indicating when and/or where non terrestrial network coverage can be available to the UE. Based on this information, the coverage data is provisioned on the UE and in the access and mobility function (AMF) in the network. Thereafter, the UE can determine when the UE is in the coverage area of the non-terrestrial network and can connect to a network node thereof, such as a base station.
