Methods and apparatus to update geographic location information associated with internet protocol devices for E-911 emergency services
First Claim
1. A method of enabling 911 services to an internet protocol communication device, the method comprising:
- receiving a media access control address associated with the internet protocol communication device and a first internet protocol address associated with a gateway through which the internet protocol communication device is obtaining network access;
retrieving a second internet protocol address associated with the media access control address;
comparing the entire first internet protocol address with the entire second internet protocol address; and
when the entire first internet protocol address does not match the entire second internet protocol address, associating the media access control address with the first internet protocol address in a database to designate a geographic location of the internet protocol communication device.

Abstract
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.
