Abstract

An eCall is an emergency call that may (i) be initiated automatically by a wireless terminal due to a trigger event (e.g., a vehicle involved in an accident) or manually by a user and (ii) include additional data sent automatically by the terminal to a recipient entity, e.g., a Public Safety Answering Point (PSAP). Depending on the implementation, Emergency setup signaling (e.g., an Emergency SETUP message) or a location updating message is used to give high priority to registering an eCall-only mode In-Vehicle System (IVS) on a mobile network. The IVS can get higher priority from the mobile network right after an eCall emergency is triggered at the IVS. When requesting a connection to the mobile network, the WS can use one or more fields of the location updating message in order to register on the network with a higher priority.

Claims

1. A method of establishing an emergency call, comprising:

triggering an emergency in a vehicle comprising an in-vehicle system (IVS) for making an emergency call via a mobile network;

generating a location updating message for the emergency call at the IVS;

transmitting the location updating message from the WS to the mobile network for registering the IVS on the mobile network;

generating an emergency setup message at the IVS; and

transmitting the emergency setup message from the IVS to the mobile network for establishing the emergency call.

2. The method of claim 1, further comprising receiving a high priority for registration of the IVS on the mobile network responsive to the location updating message being received at the mobile network.

3. The method of claim 2, wherein the IVS is registered on the mobile network with the high priority.

4. The method of claim 3, further comprising initiating the emergency call by the IVS over the mobile network after the IVS is registered on the mobile network.

5. The method of claim 4, wherein the emergency call is initiated by the IVS using the emergency setup message.

6. The method of claim 1, wherein the IVS is only operable to place a call in emergency mode.

7. The method of claim 1, wherein the location updating message comprises an indicator indicating registration for an emergency call.

8. The method of claim 7, wherein the indicator comprises a location updating type having a cause value for emergency call registration.

9. The method of claim 7, wherein the indicator comprises additional updating information containing a value for emergency call registration.

10. The method of claim 1, wherein the emergency setup message comprises a service category information element having at least one bit used for an emergency call indicator.

11. The method of claim 1, wherein the WS is registered immediately on the mobile network responsive to the location updating message being received at the mobile network.

12. The method of claim 11, wherein the IVS is registered immediately on the mobile network regardless of whether the mobile network is a visited network or a home network.

13. The method of claim 1, wherein the mobile network is a visited network.

14. The method of claim 1, wherein the mobile network is a home network.

15. An apparatus for establishing an emergency call, comprising:

means for triggering an emergency in a vehicle comprising an in-vehicle system (IVS) for making an emergency call via a mobile network;

means for generating a location updating message for the emergency call at the IVS;

means for transmitting the location updating message from the IVS to the mobile network for registering the IVS on the mobile network;

means for generating an emergency setup message at the IVS; and

means for transmitting the emergency setup message from the IVS to the mobile network for establishing the emergency call.

16. The apparatus of claim 15, further comprising means for receiving a high priority for registration of the IVS on the mobile network responsive to the location updating message being received at the mobile network.

17. The apparatus of claim 16, wherein the IVS is registered on the mobile network with the high priority.

18. The apparatus of claim 17, further comprising means for initiating the emergency call by the IVS over the mobile network after the IVS is registered on the mobile network.

19. The apparatus of claim 18, wherein the emergency call is initiated by the IVS using the emergency setup message.

20. The apparatus of claim 15, wherein the IVS is only operable to place a call in emergency mode.

21. The apparatus of claim 15, wherein the location updating message comprises an indicator indicating registration for an emergency call.

22. The apparatus of claim 21, wherein the indicator comprises a location updating type having a cause value for emergency call registration.

23. The apparatus of claim 21, wherein the indicator comprises additional updating information containing a value for emergency call registration.

24. The apparatus of claim 15, wherein the emergency setup message comprises a service category information element having at least one bit used for an emergency call indicator.

25. The apparatus of claim 15, wherein the IVS is registered immediately on the mobile network responsive to the location updating message being received at the mobile network.

26. The apparatus of claim 25, wherein the IVS is registered immediately on the mobile network regardless of whether the mobile network is a visited network or a home network.

27. The apparatus of claim 15, wherein the mobile network is a visited network.

28. The apparatus of claim 15, wherein the mobile network is a home network.

29. A non-transitory computer-readable medium comprising instructions that cause a computer to:

trigger an emergency in a vehicle comprising an in-vehicle system (IVS) for making an emergency call via a mobile network;

generate a location updating message for the emergency call at the IVS;

transmit the location updating message from the IVS to the mobile network for registering the IVS on the mobile network;

generate an emergency setup message at the IVS; and

transmit the emergency setup message from the IVS to the mobile network for establishing the emergency call.

30. The computer-readable medium of claim 29, further comprising computer-executable instructions that cause the computer to receive a high priority for registration of the IVS on the mobile network responsive to the location updating message being received at the mobile network.
