Emergency calling for multi-SIM devices

摘要

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.

1. A method for a dual subscriber identity module (SIM) device to perform emergency calling, the method comprising:
by a wireless user equipment (UE) device: receiving an indication to initiate an emergency call; selecting a cell on which to initiate the emergency call,
wherein the UE comprises at least a first subscriber identity module (SIM) and a second SIM,wherein selecting the cell on which to initiate the emergency call is based at least in part on information from the second SIM if a serving cell of the first SIM is not available for the emergency call, wherein the information from the second SIM comprises an indication of a serving cell of the second SIM and one or more neighboring cells of the second SIM, and initiating the emergency call via the selected cell using the first SIM.
