Abstract

A location device for associating a physical location with a communications device. The communications device has assigned device identification and uses an assigned network address for use in routing call data over a communications network. The location device comprises a memory for storing location information related to the physical location and a device port for coupling to the communications device and a network port for coupling to the communications network. The ports are configured for communicating the call data between the ports. The device also has a monitoring module configured for monitoring operation of at least one of the ports in order to detect an initialization process of the communications device, as well as to identify the assigned device identification. The device also has a location registration module configured for communicating a location update message over the communications network via the network port in response to the detected initialization process, such that the location update message including the location information and the identified device identification.

Claims

1. A location device for associating a physical location with a communications device, the communications device configured for having an assigned device identification and configured for using an assigned network address for use in routing call data over a communications network, the location device comprising:

a memory for storing location information related to the physical location;

a device port for coupling to the communications device and a network port for coupling to the communications network, the ports configured for communicating the call data between the ports;

a monitoring module configured for monitoring operation of at least one of the ports for detecting an initialization process of the communications device and for identifying the assigned device identification; and

a location registration module configured for communicating a location update message over the communications network via the network port in response to the detected initialization process, the location update message including the location information and the identified device identification.

2. The location device of claim 1, wherein the initialization process is selected from the group comprising:

a power-up process for supplying the communications device with operating power; and

an addressing process for assigning the network address to the communications device.

3. The location device of claim 2, wherein the power-up process is a multistage process.

4. The location device of claim 2, wherein location information is selected from the group comprising:

location identification assigned to the location device for use in accessing a definition of the physical location; and

a definition of the physical location.

5. The location device of claim 4, wherein the addressing process includes a request message for the network address, the addressing process selected from the group comprising:

SIP;

DHCP; and

BOOTP.

6. The location device of claim 4 further comprising a connection for connecting to a power source for supplying operating power to the location device.

7. The location device of claim 6, wherein the power source is selected from the group comprising:

inline power; and

an independent power supply.

8. The location device of claim 7 further comprising the connection as part of the network port and further coupled to the device port for providing inline power to the communications device.

9. The location device of claim 8, wherein the device identification is a MAC address.

10. The location device of claim 9, wherein the physical address is that of the location device.

11. The location device of claim 8, wherein the definition of the physical location includes information selected from the group comprising:

a street address;

a mailing address;

a geographical coordinate; and

a description of a location within the physical location.

12. The location device of claim 11, wherein the communications device is selected from the group comprising:

an IP phone;

a computer configured for IP telephony; and

an analogue phone connected to an ATA.

13. The location device of claim 12 further comprising a configuration module for configuring the content of the location information.

14. A method for associating a physical location with a communications device, the communications device configured for having an assigned device identification and configured for using an assigned network address for use in routing call data over a communications network, the method comprising the acts of:

storing location information related to the physical location;

coupling to the communications device and a network port for coupling to the communications network;

monitoring operation of at least one of a network port coupled to the communications network and a device port coupled to the communications device for detecting an initialization process of the communications device and for identifying the assigned device identification, the ports configured for communicating the call data between the ports; and

communicating a location update message over the communications network via the network port in response to the detected initialization process, the location update message including the location information and the identified device identification.

15. The method of claim 14, wherein the initialization process is selected from the group comprising:

a power-up process for supplying the communications device with operating power;

and an addressing process for assigning the network address to the communications device.

16. The method of claim 15, wherein location information is selected from the group comprising:

location identification assigned to a location device having the ports for use in accessing a definition of the physical location; and
