1. A method comprising:
- detecting when a voice over Internet protocol device is inside an access network by determining the voice over Internet protocol device is inside the access network if a media access control address of the voice over Internet protocol device was previously associated with an Internet protocol address that is currently associated with the voice over Internet protocol device;
when the media access control address was not previously associated with the Internet protocol address that is currently associated with the voice over Internet protocol device, determining the voice over Internet protocol device is inside the access network if the Internet protocol address is listed in a database of Internet protocol addresses associated with the access network;
prompting a user of the voice over Internet protocol device to provide geographic location information for the voice over Internet protocol device when both (1) the media access control address was not previously associated with the Internet protocol address and (2) when the Internet protocol address is not listed in the database of Internet protocol addresses; and
updating enhanced 911 information for the voice over Internet protocol device based on the geographic location information.

Abstract
Methods and apparatus provide enhanced 911 (E911) services for nomadic users are disclosed. An example method comprises receiving an Internet protocol (IP) address associated with a voice over internet protocol (VoIP) device and a media access control (MAC) address associated with the VoIP device, detecting when the VoIP device is outside an access network based on the MAC address and the IP address, prompting a user of the VoIP device to provide geographic location information for the VoIP device when the VoIP device is outside the access network, and updating enhanced 911 (E911) information for the VoIP device based on the geographic location information.

16. An apparatus comprising:
-
a processor; and a memory comprising machine readable instructions that, when executed by the processor, cause the processor to perform operations comprising; detecting when a voice over Internet protocol device is inside an access network by determining a voice over Internet protocol device is inside the access network if a media access control address of the voice over Internet protocol device was previously associated with an Internet protocol address that is currently associated with the voice over Internet protocol device; when the media access control address of the voice over Internet protocol device was not previously associated with the Internet protocol address that is currently associated with the voice over Internet protocol device, determining the voice over Internet protocol device is inside the access network if the Internet protocol address is listed in a database of Internet protocol addresses associated with the access network; prompting a user of the voice over Internet protocol device to provide geographic location information for the voice over Internet protocol device when both (1) the media access control address was not previously associated with the Internet protocol address and (2) when the Internet protocol address is not listed in the database of Internet protocol addresses; and updating enhanced 911 information for the voice over Internet protocol device based on the geographic location information. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24)

25. A tangible machine readable storage device comprising machine readable instructions which, when executed, cause a logic circuit to at least:
-
detect when a voice over Internet protocol device is inside an access network by determining the voice over Internet protocol device is inside the access network if a media access control address of the voice over Internet protocol device was previously associated with an Internet protocol address that is currently associated with the voice over Internet protocol device; when the media access control address was not previously associated with the Internet protocol address that is currently associated with the voice over Internet protocol device, determine the voice over Internet protocol device is inside the access network if the Internet protocol address is listed in a database of Internet protocol addresses associated with the access network; prompt a user of the voice over Internet protocol device to provide geographic location information for the voice over Internet protocol device when both (1) the media access control address was not previously associated with the Internet protocol address and (2) when the Internet protocol address is not listed in the database of Internet protocol addresses; and update enhanced 911 information for the voice over Internet protocol device based on the geographic location information.
