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: Distributing messages received by a cellular device via cellular broadcast to additional electronic devices. The cellular device may receive a first message via a cellular broadcast technique. The cellular device may discover another electronic device. The cellular device may provide an indication of the first message to other electronic device. The indication of the first message may cause the other electronic device to provide a user alert at the other electronic device.

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 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: Apparatuses, systems, and methods for multi-SIM user equipment (UE) devices to perform emergency calling. A UE may receive an indication to initiate an emergency call. The UE may select a cell on which to initiate the emergency call. If a serving cell of a first SIM of the UE is not available for the emergency call, the UE may utilize information from a second SIM of the UE as part of selecting the cell on which to initiate the emergency call. The information from the second SIM may include an indication of a serving cell of the second SIM. Alternatively or in addition, the information from the second SIM may include an indication of one or more neighboring cells of the second SIM. The emergency call may be initiated via the selected cell using the first SIM.
