Abstract
Solutions for routing an emergency call made through a non-terrestrial network (NTN) include: receiving, by an NTN, from a user equipment (UE), an emergency call; not selecting, by the NTN, a public safety answering point (PSAP) for routing the emergency call; selecting, by the NTN, a packet data network (PDN) gateway (GW) in a terrestrial network (TN) to which to route the emergency call; and routing the emergency call to the selected PDN GW. Solutions also include: receiving, by the TN, from the NTN, the emergency call placed by the UE that is using the NTN; determining, by the TN, a location of the UE; selecting, by the TN, a PSAP using the location of the UE; and routing the emergency call to the selected PSAP.
