Abstract

Providing enhanced emergency services (E-911) to an IP Telephony-based PBX or similar system, by utilizing aspects of the intelligence of end-user SIP client devices to address challenges and difficulties associated with E-911-like services in LAN-based telephony environments.

Claims

1-69. -69. (canceled)

70. An apparatus for communicating over a packet based network, said apparatus comprising:

logic to send a request for communication services in the packet based network, to receive a registration response from the packet based network that includes an emergency response location (ERL) record, said ERL record being associated with the ERL of the apparatus, and to transmit at least a portion of the ERL record as part of an emergency call setup process; and

a processor for implementing the logic.

71. The apparatus of claim 70, wherein the ERL record includes one or more emergency location identification numbers (ELINs), and wherein the logic is to transmit at least one of the ELINs.

72. The apparatus of claim 70, wherein the packet based network is an Internet Protocol network.

73. The apparatus of claim 70, wherein the logic is to use the Session Initiation Protocol.

74. The apparatus of claim 70, wherein the ERL record includes one or more ELINs, and wherein the logic is to transmit at least one of the ELINs in a session description protocol (SDP) contained in a SIP INVITE message.

75. The apparatus of claim 70, wherein the logic is to transmit at least a portion of the ERL record to a public switched telephone network (PSTN) gateway device, wherein the logic is to select the PSTN gateway device according information in the ERL record, wherein the at least a portion of the ERL record comprises an ERL ID, and wherein the PSTN gateway device is to insert a corresponding ELN into the caller identification portion of an outgoing 911 call.

76. The apparatus of claim 70, wherein the logic is to transmit at least a portion of the ERL record to a PSTN gateway device, wherein the at least a portion of the ERL record comprises one or more ELINs, and wherein the PSTN gateway device is to insert one of the ELINs into the caller identification portion of an outgoing 911 call.

77. The apparatus of claim 70, wherein the logic is to transmit at least a portion of the ERL record to a call signaling device, wherein the logic is to select the call signaling device, wherein the at least a portion of the ERL record comprises an ERL ID, and wherein the signaling device is to transmit a request to a PSTN gateway device to make an outgoing 911 call using an ELIN inserted into a caller identification portion of the outgoing call.

78. The apparatus of claim 70, wherein the logic is to transmit at least a portion of the ERL record to a call signaling device, wherein the at least a portion of the ERL record comprises one or more ELINs, wherein the signaling device is to select an ELIN, and wherein the signaling device is to transmit a request to a PSTN gateway to make an outgoing 911 call using an ELIN inserted into the caller identification portion of the outgoing call.

79. The apparatus of claim 70, wherein the apparatus comprises an internet protocol (IP) address and wherein the ERL of the apparatus is based in part on the IP address of the apparatus.

80. The apparatus of claim 70, wherein the apparatus comprises a media access control (MAC) address and wherein the ERL of the apparatus is based in part on the MAC address of the apparatus.

81. The apparatus of claim 70, wherein the apparatus comprises a serial number, and wherein the ERL of the apparatus is based in part on the serial number of the apparatus.

82. The apparatus of claim 70, wherein the logic is further to transmit an address of a PSTN gateway device for use during an emergency call.

83. An apparatus for communicating over a packet based network, said apparatus comprising:

logic to receive a request from a device to register for communication services in the packet based network, to determine an ERL of the device, and to transmit to the device a registration response that includes a corresponding ERL record, said ERL record including parameters enabling the device to initiate an emergency 911 call; and

a processor to implement the logic.

84. The apparatus of claim 83, wherein the logic is to use SIP to transmit the registration response that includes the ERL record.

85. The apparatus of claim 83, wherein the request to register for communication services comprises a SIP REGISTER message, and the registration response that includes the ERL record is a SIP OK message, issued in response to the SIP REGISTER message from the packet based phone to a SIP network.

86. The apparatus of claim 83, wherein the logic is to determine the ERL of the device based on at least one of an IP address, a MAC address, and a serial number of the device.

87. A non-transitory computer readable storage medium on which is embedded a computer program, said computer program implementing a method of configuring an apparatus for initiating an emergency call in a packet based network, said computer program comprising a set of instructions to:

responsive to sending a request from the apparatus to register for communication services in the packet based network, receive at the apparatus a registration response from the packet based network that includes an ERL record, said ERL record being associated with the ERL of the apparatus; and

transmit from the apparatus at least a portion of the ERL record as part of an emergency call setup process.

88. A non-transitory computer readable storage medium on which is embedded a computer program, said computer program implementing a method of configuring an apparatus for initiating an emergency call in a packet based network, said computer program comprising a set of instructions to:

responsive to receiving a request from the apparatus to register for communication services in the packet based network, determine an ERL of the apparatus; and

transmit to the apparatus a registration response that includes a corresponding ERL record, said ERL record including parameters enabling the apparatus to initiate an emergency 911 call.
