Location Determination for a Packet-Switched Device for Providing Location-Based Services
First Claim
1. A device operable to determine location of a packet-switched device, whereby the location is operable to be used to provide location-based services for the packet-switched device, the device comprising:
- an interface receiving a message, wherein the message includes a tag inserted by an access point between the packet-switched device and the device;
a database storing a plurality of tags and a location for each tag; and
a processor parsing the message to identify the tag, and performing a lookup on the database using the tag to determine a corresponding location for the tag, wherein the location is an estimation of a location of the packet-switched device and the location is operable to be used to provide a location-based service for the packet-switched device.

Abstract
A device is operable to determine location of a packet-switched device, and the location is used to provide location-based services for the packet-switched device. The device includes an interface receiving a message. The message includes a tag inserted by an access point between the packet-switched device and the device. A database stores a plurality of tags and a location for each tag. The device parses the received message to identify the tag, and performs a lookup on the database using the tag to determine a corresponding location for the tag. This location is an estimation of a location of the packet-switched device, and the location is operable to be used to provide a location-based service for the packet-switched device.
