Emergency calling in a fifth generation (5G) new

1. An apparatus of a user equipment (UE) operable to encode an emergency contact list for transmission to an emergency center, the apparatus comprising:

one or more processors configured to:

initiate an emergency call at the UE with the emergency center;

identify, at the UE, the emergency contact list stored at the UE; and

encode, at the UE, an INVITE emergency message for transmission to the emergency center via a network device, wherein the INVITE emergency message indicates that the UE is capable of sending the emergency contact list to the network device; and

encode, at the UE, a message that includes the emergency contact list for transmission to the emergency center via a network device to enable an operator at the emergency center to identify an emergency contact on the emergency contact list; and

a memory interface configured to retrieve from a memory the emergency contact list.

2. The apparatus of claim 1 , further comprising a transceiver configured to transmit the message that includes the emergency contact list to the emergency center via the network device.

3. The apparatus of claim 1 , wherein the message that includes the emergency contact list enables the operator at the emergency center to initiate a communication with a second UE associated with a person on the emergency contact list.

4. The apparatus of claim 1 ,

wherein the network device is an Internet Protocol (IP) Multimedia Subsystem (IMS); and wherein the one or more processors are configured to:

decode a 200 OK message received from the emergency center via the network device, wherein the 200 OK message indicates the emergency center is capable of retrieving and processing the emergency contact list from the UE.

5. The apparatus of claim 4 , wherein the one or more processors are configured to: establish the emergency call between the UE and the emergency center via the network device after the 200 OK message is received at the UE.

6. The apparatus of claim 1 , wherein the one or more processors are configured to:

decode an INFO request message received from the emergency center via the network device that includes a request for sending the emergency contact list; and

wherein the message that includes the emergency contact list is an INFO message.

7. The apparatus of claim 1 , wherein the one or more processors are configured to:

decode a 200 OK message received from the emergency center via the network device after the INVITE message is received at the emergency center;

encode an acknowledgement (ACK) for transmission to the emergency center via the network device; and

establish the emergency call between the UE and the emergency center via the network device after the 200 OK message is received at the UE and the ACK is transmitted from the UE.

8. The apparatus of claim 1 , wherein the emergency contact list is an Extensible Markup Language (XML)-formatted contact list.

9. The apparatus of claim 1 , wherein a receipt of the emergency contact list causes a public safety answering point (PSAP) operator at the emergency center to create a conference with a person on the emergency contact list via a second UE using session initiation protocol (SIP) signaling with a conference server.

10. The apparatus of claim 1 , wherein a public safety answering point (PSAP) operator at the emergency center is enabled to create a conference during a PSAP callback using session initiation protocol (SIP) signaling with a conference server and add one or more of the UE or a second UE associated with a person on the emergency contact list using the PSAP callback.

11. An apparatus of a network device operable to decode an emergency contact list received from a user equipment (UE), the apparatus comprising:

one or more processors configured to:

decode, at the network device, an INVITE emergency message received from the UE, wherein the INVITE emergency message indicates that the UE is capable of sending the emergency contact list to the network device;

decode, at the network device, a message received from the UE that includes the emergency contact list associated with an emergency call; and

forward the emergency contact list to an emergency center; and

initiate, at the network device, a communication with a second UE associated with a person on the emergency contact list; and

a memory interface configured to send to a memory the emergency contact list.

12. The apparatus of claim 11 , further comprising a transceiver configured to receive the message that includes the emergency contact list from the UE.

13. The apparatus of claim 11 , wherein the network device is an Internet Protocol (IP) Multimedia Subsystem (IMS).

14. The apparatus of claim 11 , wherein the one or more processors are configured to:

forward the INVITE emergency message to the emergency center; and

encode a 200 OK message for transmission to the UE, wherein the 200 OK message indicates the emergency center is capable of retrieving and processing the emergency contact list from the UE.

15. The apparatus of claim 14 , wherein the one or more processors are configured to: establish the emergency call between the UE and the emergency center after the 200 OK message is transmitted to the UE.

16. The apparatus of claim 11 , wherein the one or more processors are configured to:

decode an INFO request message received from the emergency center that includes a request for the emergency contact list; and

forward the INFO request message to the UE,

wherein the message that includes the emergency contact list is an INFO message.

17. The apparatus of claim 11 , wherein: the one or more processors are configured to:

encode a 200 OK message for transmission to the UE after the INVITE message is received at the network device;

decode an acknowledgement (ACK) received from the UE; and

establish the emergency call between the UE and the emergency center after the 200 OK message is transmitted to the UE and the ACK is received from the UE.

18. The apparatus of claim 11 , wherein the emergency contact list is an Extensible Markup Language (XML)-formatted contact list.

19. At least one non-transitory machine readable storage medium having instructions embodied thereon for encoding an emergency contact list for transmission from a user equipment (UE) to an emergency center, the instructions when executed by one or more processors perform the following:

initiating an emergency call at the UE with the emergency center;

identifying, at the UE, the emergency contact list stored at the UE; and

encoding an INVITE emergency message for transmission to the emergency center via the network device, wherein the INVITE emergency message indicates that the UE is capable of sending the emergency contact list to the network device; and

encoding, at the UE, a message that includes the emergency contact list for transmission to the emergency center via a network device to enable an operator at the emergency center to identify an emergency contact on the emergency contact list and initiate a communication with a second UE associated with a person on the emergency contact list.

20. The at least one non-transitory machine readable storage medium of claim 19 ,

wherein the network device is an Internet Protocol (IP) Multimedia Subsystem (IMS); and further comprising instructions when executed perform the following:

decoding a 200 OK message received from the emergency center via the network device, wherein the 200 OK message indicates the emergency center is capable of retrieving and processing the emergency contact list from the UE.
