System and method for power outage and restoration notification in an advanced metering infrastructure network
First Claim
1. A method of transmitting a meter power status, comprising:
- recognizing a power status change at a meter;
if the meter is scheduled to transmit first, transmitting a notification message to at least one neighboring meter towards a mesh gate, wherein the notification message includes a power status indicator and a meter identifier;
if the meter is not scheduled to transmit first, waiting a predetermined time period to receive a notification message from at least one neighboring meter;
responsive to receiving a notification message, adding a meter identifier to the received notification message before retransmitting the modified notification message to at least one neighboring meter;
retransmitting the notification message; and
responsive to a first failure to receive an acknowledgement from the at least one neighboring meter, retransmitting the notification message over an alternative mesh network path;
responsive to a second failure to receive an acknowledgement from the at least one neighboring meter, retransmitting the notification message through a newly discovered mesh network path; and
responsive to a third failure to receive an acknowledgement from the at least one neighboring meter, associating with a new mesh network and retransmitting the notification message over the new mesh network.

Abstract
A method and system are provided to transmit a meter power status. The method includes recognizing a power status change at a meter. The method includes, if the meter is scheduled to transmit first, transmitting a notification message to at least one neighboring meter towards a mesh gate, wherein the notification message includes a power status indicator and a meter identifier. The method includes, if the meter is not scheduled to transmit first, waiting a predetermined time period to receive a notification message from at least one neighboring meter. The method includes, responsive to receiving a notification message, adding a meter identifier to the received notification message before retransmitting the modified notification message to at least one neighboring meter. The method includes retransmitting the notification message.

7. A system for transmitting a network power status, comprising:
-
(A) a mesh network; (B) a wide area network separate from the mesh network; (C) at least one meter in communication with the mesh network, the meter configured to; recognize a power status change at a meter, if the meter is scheduled to transmit first, transmit a notification message to at least one neighboring meter towards a mesh gate, wherein the notification message includes a power status indicator and a meter identifier, if the meter is not scheduled to transmit first, wait a predetermined time period to receive a notification message from at least one neighboring meter, responsive to receiving a notification message, adding a meter identifier to the received notification message before retransmitting the modified notification message to at least one neighboring meter, and retransmitting the notification message; (D) a mesh gate in communication with the meter over the mesh network and in communication with the wide area network, the mesh gate configured to; receive at least one notification message from a meter, wherein the notification messages include a power status indicator and at least one meter identifier, aggregate the received meter identifiers into a composite notification message, the composite notification message include a power status indicator and at least one meter identifier, transmit the composite notification message to a server over a wide area network, and retransmitting the composite notification message; and (E) a server in communication with the mesh gate over the wide area network, the server configured to receive the composite notification message. - View Dependent Claims (8, 9, 10, 11, 12)

13. A method of transmitting a meter power status, comprising:
-
recognizing a power status change at a meter; if the meter is scheduled to transmit first, transmitting a notification message from the meter to at least one neighboring meter towards a mesh gate, wherein the notification message includes a power status indicator and a meter identifier; if the meter is not scheduled to transmit first, waiting a predetermined time period to receive a notification message from at least one neighboring meter; responsive to receiving a notification message, adding a meter identifier to the received notification message before retransmitting the modified notification message to at least one neighboring meter, wherein the notification message include a power status indicator and at least one meter identifier; aggregating the received meter identifiers into a composite notification message, the composite notification message including a power status indicator and at least one meter identifier; transmitting the composite notification message to a server over a wide area network; and retransmitting the composite notification message.

14. A computer program stored in a computer readable form for execution in a processor and a processor coupled memory to implement a method of transmitting a meter power status, the method comprising:
-
recognizing a power status change at a meter; if the meter is scheduled to transmit first, transmitting a notification message from the meter to at least one neighboring meter towards a mesh gate, wherein the notification message includes a power status indicator and a meter identifier; if the meter is not scheduled to transmit first, waiting a predetermined time period to receive a notification message from at least one neighboring meter; responsive to receiving a notification message, adding a meter identifier to the received notification message before retransmitting the modified notification message to at least one neighboring meter, wherein the notification message include a power status indicator and at least one meter identifier; aggregating the received meter identifiers into a composite notification message, the composite notification message including a power status indicator and at least one meter identifier; transmitting the composite notification message to a server over a wide area network; and retransmitting the composite notification message.
