System for dynamically tracking the location of network devices to enable emergency services
First Claim
1. An apparatus comprising:
- a communication facility configured to source and sink messages in a computer network via at least one network port coupled to the computer network;
a radio frequency (RF) receiver configured to receive beacon signals transmitted by a plurality of base stations, the base stations located in a building, each beacon signal encoded with location information descriptive of the location of one of the base stations; and
a location determination engine configured to compute a location of the apparatus based on the location information encoded in the beacon signals, the computed location being a point within the building.

Abstract
A system and/or method to determine the location within a building of an apparatus, such as a personal computer, coupled to a computer network. A communication facility of the apparatus is configured to source and sink messages in the computer network via at least one network port coupled to the computer network. A radio frequency (RF) receiver of the apparatus is configured to receive beacon signals transmitted by a plurality of base stations, the base stations located in the building, each beacon signal encoded with location information descriptive of the location of one of the base stations. Also, a location determination engine of the apparatus is configured to compute a location of the apparatus based on the location information encoded in the beacon signals, the computed location being a point within the building.

16. A method comprising:
-
receiving beacon signals transmitted by a plurality of base stations, the base stations located in a building, each beacon signal encoded with location information describing the location of one of the base stations; and
computing a location of an apparatus based on the location information encoded in the beacon signals, the computed location being a point within the building;
transmitting one or more location identifier (ID) messages onto a computer network via at least one network port of the apparatus coupled to the computer network, the messages including the computed location within the building. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29)
