1. An apparatus comprising:
- a network component that is part of a trust domain configured to;
receive from a user equipment (“
UE”
) a Session Initiation Protocol (“
SIP”
) request message for a dialog that is an emergency-related request;
update header information of the SIP request message for a dialog;
forward the SIP request message for a dialog toward a Public Safety Answering Point (“
PSAP”
);
send to the UE a SIP response message containing a P-Asserted-Identity header field in response to the SIP request message, the P-Asserted-Identity header field comprising an emergency number, the SIP response message indicating that the SIP request message for a dialog, sent by the UE, is an emergency-related request and that the UE should include location information in a response to the SIP response message; and
receive from the UE, in response to the SIP response message, a SIP request message within the dialog, the SIP request message within the dialog containing emergency-related information comprises a UE location.

27. A tangible, non-transitory, computer readable medium storing computer readable instructions executable by a processor of a network component that is part of a trust domain to cause said network component to implement the method of:
-
receiving from a user equipment (“
UE”
) a Session Initiation Protocol (“
SIP”
) request message for a dialog that is an emergency-related request;updating header information of the SIP request message for a dialog; forwarding the SIP request message for a dialog toward a Public Safety Answering Point (“
PSAP”
);sending from the network component to the UE a SIP response message containing a P-Asserted-Identity header field in response to the SIP request message, the P-Asserted-Identity header field comprising an emergency number, the SIP response message indicating that the SIP request message for a dialog, sent by the UE, is an emergency-related request and that the UE should include location information in a response to the SIP response message; and receiving from the UE, in response to the SIP response message, a SIP request message within the dialog, the SIP request message within the dialog containing emergency-related information comprises a UE location.
