Abstract

A network component is provided. The network component including a component configured such that the network transmits a response message containing an indicator indicating that a first message is an emergency-related request, and such that the network receives a second message containing information associated with a user equipment (UE).

Claims

1-30. -30. (canceled)

31. An apparatus comprising:

a network component configured;

to send to a user equipment (UE) a response message containing an indicator indicating that a first message, sent by the UE, is an emergency-related request; and

to receive from the UE, in response to the response message, a second message containing information associated with the UE,

wherein the UE is unaware that the first message is an emergency related request.

32. The apparatus of claim 31, wherein the second message is a SIP UPDATE request.

33. The apparatus of claim 31, wherein the information associated with the UE contained in the second-message comprises a UE identity.

34. The apparatus of claim 31, wherein the information associated with the UE contained in the second message comprises a UE location.

35. The apparatus of claim 31, wherein the information associated with the UE contained in the second message comprises UE access network information.

36. The apparatus of claim 31, wherein the network component is an E-CSCF (emergency call session control function).

37. The apparatus of claim 31, wherein the first message is a SIP (Session Initiation Protocol) request.

38. The apparatus of claim 31, wherein the response message is one of a SIP 1xx or 200 (OK) response.

39. The apparatus of claim 31, wherein the second message is one of:

a SIP ACK;

a SIP PRACK;

a SIP target refresh;

a SIP UPDATE; and

a SIP RE-INVITE request.

40. The apparatus of claim 31, wherein the first message is an initial request for a dialog.

41. The apparatus of claim 33, wherein the UE identity is a globally routable user agent uniform resource identifier (GRUU).

42. The apparatus of claim 34, wherein a geolocation header field of the second message includes a URI (Uniform Resource Identifier) that points to the UE location.

43. The apparatus of claim 31, wherein the message body of the second message includes geographical location information of the UE as a PIDF location object.

44. The apparatus of claim 31, wherein a contact header field of the second message includes a public GRUU value associated with a public user identity.

45. The apparatus of claim 35, wherein the UE access network information is included in a P-Access-Network-Info header field in the second message and comprises one of a location Identifier, a cell identifier or an identity of an I-WLAN access node.

46. A method for a network component to manage emergency-related information, comprising:

the network component sending to a user equipment (UE) a response message containing an indicator indicating that a first message, sent by the UE, is an emergency-related request; and

the network component receiving from the UE, in response to the response message, a second message containing information associated with the UE,

wherein the UE is unaware that the first message is an emergency-related request.

47. The method of claim 46, wherein the second message is a SIP UPDATE request.

48. The method of claim 46, wherein the information associated with the UE contained in the second message comprises a UE identity.

49. The method of claim 46, wherein the information associated with the UE contained in the second message comprises a UE location.

50. The method of claim 46, wherein the information associated with the UE contained in the second message comprises UE access network information.

51. The method of claim 46, wherein the network component is an E-CSCF (emergency call session control function).

52. The method of claim 46, wherein the first message is a SIP (Session Initiation Protocol) request.

53. The method of claim 46, wherein the response message is one of a SIP 1xx or 200 (OK) response.

54. The method of claim 46, wherein the second message is one of:

a SIP ACK;

a SIP PRACK;

a SIP target refresh;

a SIP UPDATE; and

a SIP RE-INVITE request.

55. The method of claim 46, wherein the first message is an initial request for a dialog.

56. The method of claim 48, wherein the UE identity is a globally routable user agent uniform resource identifier (GRUU).

57. The method of claim 49, wherein a geolocation header field of the second message includes a URI (Uniform Resource Identifier) that points to the UE location.

58. The method of claim 46, wherein a message body of the second message includes geographical location information of the UE as a PIDF location object.

59. The method of claim 46, wherein a contact header field of the second message includes a public GRUU value associated with a public user identity.

60. The method of claim 50, wherein the UE access network information is included in a P-Access-Network-Info header field in the second message and comprises one of a location identifier, a cell identifier or an identity of an I-WLAN access node.
