Abstract

One example embodiment provides a method and system where a node in a utility network receives a block of IPv6 network addresses from an access point in the utility network. The utility node allocates an IP network address from the block of IPv6 network addresses received from the access point to an in-premise device which communicates to the utility node over an in-premise network which is not IP based. The utility node proxies the allocated IP address to the utility network, allowing other nodes on the utility network to address and communicate with the in-premise device.

Claims

1. A wireless communication system comprising:

a plurality of utility nodes capable of receiving commodity meter information, the utility nodes connected in a utility network, the utility nodes including an in-premise interface;

at least one access point connected in the utility network, the access point providing a block of network addresses to at least one utility node in the utility network;

wherein the in premise interface allocates a network address to an in-premise device communicating over an in-premise network from the block of network addresses received from the access point.

2. The wireless network system of claim 1, wherein network addresses are IPv6 addresses.

3. The wireless network system of claim 1, wherein the network addresses are IPv4 addresses.

4. The wireless network system of claims 2 and 3, wherein the block of network addresses received form the access point is a continuous block of network addresses.

5. The wireless network system of claims 2 and 3, wherein the allocation of the network address to the in premise device is in response to detection of the in-premise device.

6. The wireless network system of claim 5, wherein the network address allocated to the in-premise device is shared with at least one additional node in the utility network.

7. The wireless network system of claim 6, wherein the at least one additional node in the utility network is an access point.

8. The wireless network system of claim 7, wherein the network address allocated to the in-premise device is shared with at least one additional node in the utility network in response to the allocating utility node receiving an indication to share the network address allocated to the in-premise device.

9. The wireless network system of claim 1, 2 or 3, wherein the in-premise network is WPAN network.

10. The wireless network system of claim 9, wherein the WPAN network uses a communication protocol chosen from:

UWB communications protocol, ZigBee communications protocol, UDP protocol, WAP protocol, OBEX protocol, L2CAP protocol, or Blue-tooth family of protocols.

11. The wireless network system of claim 1, wherein the in-premise network also includes a PLC communications network.

12. The wireless network system of claim 10, wherein the utility node proxies the allocated network address to the utility network.

13. The wireless network of claim 12, wherein at least one back office system in communication with the utility network receives the allocated network address proxied by the utility node and sends at least one message to the in-premise device using the allocated network address.

14. The wireless network system of claim 1, wherein the utility node allocates a unique network addresses to each of a plurality of in-premise devices.

15. The wireless network system of claim 1, wherein at least one of the plurality of in-premise devices is physically located at a neighboring premise.

16. A method of communicating on a wireless utility network, comprising:

receiving an indication of the existence of at least one in-premise device over a non-IP based communications network;

receiving a block of network addresses from an access point in the utility network;

allocating a network address to the in-premise device from the received block of network addresses; and

sending an indication of the allocation of the network address with the in-premise device to at least one other node in the utility network.

17. The method of claim 16, wherein the at least one other node in the utility network is an access point.

18. The method of claim 16, wherein the associated network address is an IPv6 address.

19. The method of claim 16, wherein the non-IP based communications network is a WPAN network.

20. The method of claim 19, wherein the WPAN network uses a communication protocol chosen from:

UWB communications protocol, ZigBee communications protocol, UDP protocol, WAP protocol, OBEX protocol, L2CAP protocol, or Blue-tooth family of protocols

21. The method of claim 16, further comprising:

receiving an indication of the existence of a second in-premise device over a non-IP based communications network;

allocating a second network address with the second in-premise device; and

sending an indication of the allocation of the second network address with the second in-premise device to at least one other node in the utility network.

22. The method of claim 21, further comprising:

receiving a message from at least one of the in-premise devices intended for a node on the utility network, wherein the received message was received from non-IP based communications network;

sending at least one packet on the utility network addressed to the intended node on the utility network, wherein the at least one packet sent includes the associated network address of the at least one of the in-premise device associated with the received message.

23. The method of claim 22, wherein the intended node on the utility network is an access point, the access point forwarding the packet to node on a communication network the access point is in communication with.

24. The method of claim 16, wherein the associated network address is an IPv4 address.
