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.
Claims20
A method of routing an emergency call made through a non-terrestrial network (NTN), the method comprising:
- 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.
A system for routing an emergency call made through a non-terrestrial network (NTN), the system comprising:
- a processor;
- and
- a computer-readable medium storing instructions that are operative upon execution by the processor to:
- receive, by an NTN, from a user equipment (UE), an emergency call;
- not select, by the NTN, a public safety answering point (PSAP) for routing the emergency call;
- select, by the NTN, a packet data network (PDN) gateway (GW) in a terrestrial network (TN) to which to route the emergency call;
- and
- route the emergency call to the selected PDN GW.
One or more computer storage devices having computer-executable instructions stored thereon, which, upon execution by a computer, cause the computer to perform operations comprising:
- receiving, by a non-terrestrial network (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.
