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.

Methods and apparatus to provide enhanced 911 (E911) services for nomadic users

Example methods and apparatus to enable 911 services to an internet protocol ('IP') communication device are disclosed. A disclosed example method involves receiving a media access control address associated with the IP communication device and a first internet protocol address associated with a gateway through which the IP communication device is obtaining network access. A second internet protocol address associated with the media access control address is then retrieved. The first internet protocol address with the second internet protocol address are then compared. When the first internet protocol address does not match the second internet protocol address, the media access control address is associated with the first internet protocol address in a database to designate a geographic location of the device.
