Abstract: Apparatuses, systems, and methods for a wireless device to perform methods for de-registration of the wireless device from a first access type over a second access type. Methods also include procedures for maintaining state machines associated with both access types as well as procedures to determine a connection for re-transmitting a de-registration request and to avoid collisions between procedures associated with the first and second access types. Further, methods include an information element configured to indicate which access type has been de-registered.

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: 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: 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: 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: Embodiments are presented herein of apparatuses, systems, and methods for a user equipment device (UE) to determine whether or not a mobile alert message is in effect. Such a determination may be based on a cancellation message (or other message(s) received from the network, possibly in response to a query from the UE. Alternatively or additionally, such a determination may be based on monitoring rebroadcasts of the alert and/or determining that no rebroadcast has been received for a period of time.

Abstract: An accessory device may dynamically determine to transition a cellular connection between mobile-initiated communication only (MICO) mode and non-MICO mode based on a variety of factors. The accessory device may be configured to communicate through a non-cellular network in addition to the cellular network. The accessory device may transition from MICO to non-MICO mode based on one or more of: loss of the non-cellular connection; location of the accessory device; a call, data, or SMS request failure over the non-cellular network; or other factors.

Abstract: This disclosure relates to techniques for managing mobile-terminating short message service re-transmissions for wireless devices. A cellular network entity of a cellular network may receive a request to provide a short message service message to a wireless device. The wireless device may be registered with the cellular network entity via at least two access types. An attempt to provide the short message service message to the wireless device via a first access type may be performed. An attempt to provide the short message service message to the wireless device via a second access type may be performed if the attempt to provide the short message service message to the wireless device via the first access type is unsuccessful.
