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 network system comprising:

a plurality of nodes connected in a wireless network, at least some of the nodes including an in-premise interface; and

at least one access point connected in the wireless network, the access point providing to each of at least one of the plurality of nodes in the wireless network, an indication of a block of network addresses allocated by the access point to be assigned by that node to in-premise devices registered with that node,

wherein the block of network addresses allocated to any one node is unique with respect to the block of network addresses allocated to any other node by that access point, and

wherein, for said each of the at least one of the plurality of nodes in the wireless network, the in-premise interface of the at least one node is configured to;

interact with an in-premise device for the in-premise device to register with that node and for that node to select one of the network addresses of the block of network addresses allocated by the access point to that node, and

assign the selected network address to the in-premise device registered with that node and for that node to provide an indication of the address assignment of the registered in-premise device for communication with the an in-premise device via the wireless network.

2. The wireless network system of claim 1, wherein the 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 claim 1, wherein the block of network addresses allocated by the access point is a block of IPv6 network addresses.

5. The wireless network system of claim 1, wherein the in-premise interface is configured to assign the selected network address to the in-premise device in response to detection of the in-premise device.

6. The wireless network system of claim 1, wherein the in-premise network is WPAN network.

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

8. The wireless network system of claim 1, wherein the in-premise interface is configured to assign unique network addresses to each of a plurality of in-premise devices.

9. The wireless network system of claim 1, wherein the network address is assigned to the in-premise device based on at least one of:

a device type, a device attribute, a network topology, a usage type, and a usage characteristic.

10. The wireless network system of claim 8, wherein the in-premise interface is configured to:

select a plurality of network addresses from the block of network addresses; and

assign the selected plurality of network addresses to a plurality of in-premise devices.

11. The wireless network system of claim 5, wherein the network address assigned to the in-premise device is provided to at least one additional node in the wireless network.

12. The wireless network system of claim 11, wherein the at least one additional node in the wireless network is an access point.

13. The wireless network system of claim 12, wherein the network address assigned to the in-premise device is provided to at least one additional node in the wireless network in response to the assigning node receiving an indication to provide the network address assigned to the in-premise device.

14. The wireless network system of claim 6, wherein the WPAN network uses a communication protocol selected from the group consisting of:

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

15. The wireless network system of claim 14, wherein the node proxies the assigned network address to the wireless network.

16. The wireless network of claim 15, comprising:

at least one back office system in communication with the wireless network, the at least one back office system being configured to receive the assigned network address proxied by the node and send at least one message to the in-premise device using the assigned network address.

17. The wireless network system of claim 8, wherein at least one of the plurality of in-premise devices is physically located at a neighboring premise.
