Abstract: A communications system may include a user equipment (UE) device, a cellular network, a core network, and an emergency alert originator that broadcasts an emergency alert. The core network transmits a message to the UE that identifies a first region associated with the alert. The cellular network transmits a message to the UE that identifies a second region associated with the alert. The UE generates an expanded region as a hull around the first region and monitors its location relative to the hull. The UE displays a message body of the alert if/when the UE is within the hull and the first region is sufficiently similar to the second region. This may allow the UE to inform a user of the alert as rapidly as possible, regardless of how the cellular network and/or the core network interpret the emergency alert broadcast by the emergency alert originator.

Abstract: Embodiments are presented herein of apparatuses, systems, and methods for a user equipment device (UE), manufacturer server, and/or cellular network to perform radio capability signaling. A new type of UE radio capability identifier is provided which may allow a network to distinguish between similar UEs that have or have not implemented a capability update. In order to perform a forced capability update, a manufacturer may issue information about the update to a cellular network (and receive acknowledgement of the information) prior to pushing the update to UEs. In response to an unforced capability update, a cellular network may maintain multiple UE radio capability identifiers for similar UEs which have or have not implemented the update. A UE radio capability identifier may be adjusted dynamically in response to temporary changes in the UE's capability.

Abstract: Apparatuses, systems, and methods for a user equipment device (UE) to perform methods for enhancement of multi-SIM devices, such as UE 106. A network may increase paging retries for known MU-SIM devices, e.g., based on an indication of capabilities from a MU-SIM device. The indication may be via a NAS registration request, an RRC capability procedure, and/or an RRC UE assistance procedure. Additionally, a network may include an indication of a paging priority to the UE. The UE may then determine a response to the page based, at least in part, on the indicated priority. Further, the UE may indicate a tune-away to the network. The indication of the tune-away may include a cause and/or duration for the tune-away and may be provided at an RRC level or a network access stratum (NAS) level.

Abstract: A mobile device (UE) may access standalone non-public networks (SNPNs) in various different locations as equivalent SNPNs (eSNPNs) corresponding to a home SNPN of the device. The device may obtain a list of eSNPNs corresponding to the home SNPN, and may access a second SNPN at a location different from a location of the home SNPN, in response to identifying the second SNPN and the list including the second SNPN as an eSNPN corresponding to the home SNPN of the device. The eSNPNs may include roaming eSNPNs (ReSNPNs) for accessing an enterprise NPN globally and/or at various different locations. The eSNPN/ReSNPN list may be maintained in a new network identifier management function (NMF). NPNs may be implemented as network slice instances (NSIs) via identifying data in the single network slice selection assistance information (S-NSSAI). Multiple credentialed SNPNs of a UE may be prioritized for access by the UE.

Abstract: A user equipment (UE) is configured with operations to determine whether a network supports non-voice IP Multimedia Subsystem (IMS) services. The UE determines whether a network with which the UE is communicating supports a non-voice IP Multimedia Subsystem (IMS) service and when the network supports the non-voice IMS service, initiates an IMS Protocol Data Unit (PDU) session establishment with the network.

Abstract: A base station receives an alert indicating a geofenced area, and determines whether its coverage area is completely within the area. If so, the base station generates/sends a wireless emergency alert (WEA) to user equipment in the coverage area that does not indicate the area. Otherwise, the base station generates/sends a WEA that indicates the area. The base station sends action messages that indicate a periodicity and end time for the user equipment to determine whether its location is within the geofenced area, a lack of service time limit and lack of service action for the user equipment to perform after it has been without cellular service for the lack of service time limit, a lack of location time limit and lack of location action for the user equipment to perform if its location cannot be determined for the lack of location time limit, and/or that the WEA has ended.

Abstract: A user equipment (UE) may be configured to reattempt to establish a multiple access (MA) protocol data unit (PDU) session when the UE moves to a new registration area. The UE transmits a request for a MA PDU session to the network, receives a message from the network indicating the request has been rejected, wherein the message further includes a status indication for reattempt requests to establish the MA PDU session, determines, when the UE moves into a new registration area of a PLMN, whether reattempt requests are allowed based on, at least, the status indication and transmits, when reattempt requests are allowed, a further request to establish the MA PDU session.

Abstract: This Application sets forth techniques for routing emergency (SMS) messages under limited-service scenarios. One technique can be implemented by a network entity associated with a mobile network operator (MNO), and include the steps of (1) receiving an SMS message from a wireless device, and (2) in response to determining that (i) the wireless device is communicatively coupled to the MNO under a limited-service connection due to being unaffiliated with the MNO, and (ii) a destination address of the SMS message corresponds to an emergency service: (a) identifying at least one emergency service provider that corresponds to the MNO, and (b) providing at least a portion of the SMS message to the emergency service provider.

Abstract: Techniques are disclosed relating to handover of WLAN voice calls to one or more cellular networks. In some embodiments, a device is configured to perform voice communications over one or more wireless local area networks, communicate with a first network using a first cellular radio access technology (RAT), and communicate with a second network using a second cellular RAT. The device may store, based on communications via the first network, information indicating that the first network does not support voice communications for the apparatus. The device may handover a voice call from a wireless local network directly to the second cellular RAT, based on the stored information and without handover of the voice call to the first cellular RAT, based on call conditions on the wireless local area network.

Abstract: Apparatus and methods to support parallel access to services of multiple subscriber identity modules (SIMs) and/or electronic SIMs (eSIMs) by a wireless device are disclosed. The wireless device is a single-radio wireless device that includes wireless circuitry that supports an active voice or video connection via a single radio access network of a cellular wireless network at a time. To send or receive data for a second SIM/eSIM, when an active voice or video connection for a first SIM/eSIM uses the wireless circuitry, the single-radio wireless device can i) establish parallel, linked protocol data unit (PDU) sessions for different SIMs, ii) multiplex traffic for different SIMs over a common radio connection with SIM information embedded in protocol headers for routing by network equipment, and/or iii) use an additional dedicated bearer using a first, active SIM for each data network name (DNN) over which to route for a second, suspended SIM.
