Abstract

A follow-on request is used in the registration request of an eCall-only mode in-vehicle system (IVS) to keep the connection alive between the registration and the emergency call setup in order to speed up the overall signaling process before sending eCall data for the eCall-only mode IVS. In this manner, two separate connections are not needed in order to perform the registration of the IVS on the mobile network and then the emergency call setup. Only one connection is used and maintained throughout registration and call setup processes. This speeds up the eCall emergency registration and call setup. In an implementation, the registration request with the follow-on request is provided only when the eCall-only IVS is activated for use in an emergency call (i.e., in an initial registration of the eCall-only IVS).

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 registration message at the IVS; and

transmitting the registration message, and a follow-on request, from the IVS to the mobile network, via a connection between the IVS and the mobile network, for registering the IVS on the mobile network.

2. The method of claim 1, wherein the IVS is registered on the mobile network responsive to the registration message being received at the mobile network, and the connection between the IVS and the mobile network is maintained.

3. The method of claim 2, further comprising initiating an emergency call by the IVS over the mobile network, using the connection, after the IVS is registered on the mobile network.

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

5. The method of claim 1, wherein the connection is an RR/RRC (radio resource/radio resource control) connection.

6. The method of claim 1, wherein the connection between the IVS and the mobile network is maintained based on the follow-on request received by the mobile network.

7. The method of claim 1, wherein the registration message comprises the follow-on request.

8. The method of claim 7, wherein the registration message comprises a first bit indicating the follow-on request and a second bit indicating an eCall-only IVS.

9. The method of claim 1, wherein the registration message with the follow-on request is provided only when the IVS is activated for use in an emergency call.

10. The method of claim 9, wherein the IVS is activated for use in an emergency call in an initial registration of an eCall-only IVS.

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

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

13. 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 registration message at the IVS; and

means for transmitting the registration message, and a follow-on request, from the IVS to the mobile network, via a connection between the IVS and the mobile network, for registering the IVS on the mobile network.

14. The apparatus of claim 13, wherein the IVS is registered on the mobile network responsive to the registration message being received at the mobile network, and the connection between the IVS and the mobile network is maintained.

15. The apparatus of claim 14, further comprising means for initiating an emergency call by the IVS over the mobile network, using the connection, after the IVS is registered on the mobile network.

16. The apparatus of claim 13, wherein the IVS is only operable to place a call in emergency mode.

17. The apparatus of claim 13, wherein the connection is an RR/RRC (radio resource/radio resource control) connection.

18. The apparatus of claim 13, wherein the connection between the IVS and the mobile network is maintained based on the follow-on request received by the mobile network.

19. The apparatus of claim 13, wherein the registration message comprises the follow-on request.

20. The apparatus of claim 19, wherein the registration message comprises a first bit indicating the follow-on request and a second bit indicating an eCall-only IVS.

21. The apparatus of claim 13, wherein the registration message with the follow-on request is provided only when the IVS is activated for use in an emergency call.

22. The apparatus of claim 21, wherein the IVS is activated for use in an emergency call in an initial registration of an eCall-only IVS.

23. The apparatus of claim 13, wherein the mobile network is a visited network.

24. The apparatus of claim 13, wherein the mobile network is a home network.

25. A 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 registration message at the IVS; and

transmit the registration message, and a follow-on request, from the IVS to the mobile network, via a connection between the IVS and the mobile network, for registering the IVS on the mobile network.

26. The computer-readable medium of claim 25, wherein the IVS is registered on the mobile network responsive to the registration message being received at the mobile network, and the connection between the IVS and the mobile network is maintained.

27. The computer-readable medium of claim 26, further comprising computer-executable instructions that cause the computer to initiate an emergency call by the IVS over the mobile network, using the connection, after the IVS is registered on the mobile network.

28. The computer-readable medium of claim 25, wherein the IVS is only operable to place a call in emergency mode.

29. The computer-readable medium of claim 25, wherein the connection is an RR/RRC (radio resource/radio resource control) connection.

30. The computer-readable medium of claim 25, wherein the connection between the IVS and the mobile network is maintained based on the follow-on request received by the mobile network.

31. The computer-readable medium of claim 25, wherein the registration message comprises the follow-on request.

32. The computer-readable medium of claim 31, wherein the registration message comprises a first bit indicating the follow-on request and a second bit indicating an eCall-only IVS.
