1. An apparatus comprising:
- a network component configured toreceive from a user equipment (UE) a Session Initiation Protocol (SIP) request message for a SIP dialog, the SIP request message containing a Request Uniform Resource Identifier (URI);
inspect the Request URI of the SIP request message for an identifier that matches an emergency service identifier in a configurable list stored by the network component;
when the Request URI matches an emergency service identifier in the configurable list;
send to the UE a SIP response message containing a P-Asserted-Identity header field with an indicator indicating that the SIP request message for a SIP dialog, sent by the UE, is an emergency-related request; and
receive from the UE, in response to the SIP response message, a SIP request message within the same SIP dialog, the SIP request message within the same SIP dialog containing emergency-related information associated with the UE comprising the UE location.

Abstract
A network component is provided that includes a processor configured to inspect requests sent to the network component to determine if the requests are related to emergencies. If one of the requests is determined to relate to an emergency, the processor is further configured, based on configurations and regulator policies, to update the request.

11. A method for a network component to manage emergency-related information, comprising:
-
receiving from a user equipment (UE) a Session Initiation Protocol (SIP) request message for a SIP dialog, the SIP request message containing a Request Uniform Resource Identifier (URI); inspecting the Request URI of the SIP request message for an identifier that matches an emergency service identifier in a configurable list stored by the network component; when the Request URI matches an emergency service identifier in the configurable list; sending from the network component to the UE a SIP response message containing a P-Asserted-Identity header field with an indicator indicating that the SIP request message for a SIP dialog, sent by the UE, was an emergency-related request; and receiving from the UE, in response to the SIP response message, a SIP request message within the same SIP dialog, the SIP request message within the same SIP dialog containing emergency-related information associated with the UE comprising the UE location. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 37, 38, 39, 40, 41, 42, 43, 44)

36. An apparatus comprising:
a network component configured to receive from a user equipment (UE) a Session Initiation Protocol (SIP) request message for a SIP dialog, the SIP request message containing a Request Uniform Resource Identifier (URI); inspect the Request URI of the SIP request message for an identifier that matches an emergency service identifier in a configurable list stored by the network component; when the Request URI matches an emergency service identifier in the configurable list; send the updated SIP request message to another network component; receive a SIP response message from the other network component, the SIP response message containing a P-Asserted-Identity header field with an indicator indicating that the SIP request message for a SIP dialog, sent by the UE is an emergency-related request; send to the UE the SIP response message; and receive from the UE, in response to the SIP response message, a SIP request message within the same SIP dialog, the SIP request message within the same SIP dialog containing emergency-related information associated with the UE comprising the UE location.

45. A method for a network component to manage emergency-related information, comprising:
-
receiving from a user equipment (UE) a Session Initiation Protocol (SIP) request message for a SIP dialog, the SIP request message containing a Request Uniform Resource Identifier (URI); inspecting the Request URI of the SIP request message for an identifier that matches an emergency service identifier in a configurable list stored by the network component; when the Request URI matches an emergency service identifier in the configurable list; sending the updated SIP request message to another network component; receiving a SIP response message from the other network component, the SIP response message containing a P-Asserted-Identity header field with an indicator indicating that the SIP request message for a SIP dialog, sent by the UE is an emergency-related request; sending from the network component to the UE the SIP response message; and receiving from the UE, in response to the SIP response message, a SIP request message within the same SIP dialog, the SIP request message within the same SIP dialog containing emergency-related information associated with the UE comprising the UE location.
