Traffic management and remote configuration in a gateway-based network
Disclosed are apparatus and methodology for remotely configuring gateway devices in a gateway-based Advanced Metering Infrastructure (AMI) network. Remotely configurable gateway devices are provided for Internet Protocol (IP) communications between consumption measuring devices and a utility central facility. Communications between the gateway device and central facility may be by way of wired or wireless communications and may include configuration information multicast from the central facility to selected gateway devices.
1. An Advanced Metering Infrastructure (AMI), comprising:
a plurality of remotely configurable gateways;
a plurality of consumption measuring devices coupled for communications with the plurality of remotely configurable gateways, wherein each consumption measuring device is assigned to a group that is associated with one of the plurality of remotely configurable gateways; and
at least one central facility server coupled for communications over one or more IP-based communications networks, wherein the at least one central facility server is configured to:
multicast configuration information from the at least one central facility server to the plurality of remotely configurable gateways; and
reconfigure a selected gateway from among the plurality of remotely configurable gateways from being configured to report consumption data from a respective group of one or more consumption measuring devices associated with the selected gateway, to being configured to report consumption data from all consumption measuring devices it hears, wherein the consumption measuring devices that the selected gateway hears and is reconfigured to report on include consumption measuring devices that are not paired with the selected gateway.
2. The AMI of claim 1 , wherein the configuration information assigns the selected gateway to report data from at least one specific consumption measuring device.
3. The AMI of claim 1 , wherein the configuration information assigns the selected remotely configurable gateway to report data from a specific type of consumption measuring device.
4. The AMI of claim 1 , wherein the configuration information configures the selected remotely configurable gateway to operate within a Polling-Based Network.
5. The AMI of claim 1 , wherein the configuration information configures the selected remotely configurable gateway to operate within a Push-Based System.
6. The AMI of claim 1 , wherein the configuration information configures the selected remotely configurable gateway into two or more multicast groups, each of the two or more multicast groups comprising:
a utility-type multicast group;
a geographic area based multicast group;
an internet service provider based multicast group; or
a service type multicast group based on residential vs. commercial service.
7. The AMI of claim 1 , wherein the configuration information instructs the remotely configurable gateway to assist in determining an extent of a power or service outage at least in part by instructing the remotely configurable gateway to report data from all consumption measuring devices that it can hear.
8. A method for changing a configuration of a remotely configurable gateway, wherein the remotely configurable gateway is coupled between one or more utility consumption measuring devices and a utility provider, the method comprising:
communicating with at least one utility consumption measuring device using Internet Protocol (IP) based communications;
communicating with the utility provider; and
receiving configuration information via multicast from the utility provider, wherein the configuration information reconfigures the remotely configurable gateway from reporting consumption data from a group of one or more utility consumption measuring devices associated with the remotely configurable gateway to reporting consumption data from all of the utility consumption measuring devices that are heard by the remotely configurable gateway, wherein the utility consumption measuring devices that are heard by the remotely configurable gateway, and are to be reported on by the remotely configurable gateway, include utility consumption measuring devices that are not paired with the remotely configurable gateway.
9. The method of claim 8 , wherein the configuration information configures the remotely configurable gateway to periodically push readings, alarms and/or tampers to the utility provider.
10. The method of claim 8 , wherein the configuration information configures the remotely configurable gateway to return time-stamped information in response to polling by the utility provider.
11. The method of claim 8 , wherein the configuration information configures the remotely configurable gateway to set filtering parameters, set schedules for operations and return radio performance statistics to the utility provider.
12. The method of claim 8 , wherein the configuration information configures the remotely configurable gateway, previously configured to report data from a single utility consumption measuring device, to report data from all utility consumption measuring devices heard by the remotely configurable gateway.
13. A method by which a computing device of a utility provider sends configuration information to a plurality of remotely configurable gateways, the remotely configurable gateways in communication with one or more utility consumption measuring devices in an Internet Protocol (IP) based communications network, the method comprising:
multicasting configuration information to the plurality of remotely configurable gateways; and
reconfiguring a selected gateway of the plurality of remotely configurable gateways according to the configuration information from reception of consumption information from only utility consumption measuring devices in a respective group associated with the selected gateway to reception of consumption information from all utility consumption measuring devices that are heard by the selected gateway, wherein the utility consumption measuring devices that the selected gateway hears and from which the selected gateway is reconfigured to receive consumption information, include utility consumption measuring devices that are not paired with the selected gateway.
14. The method of claim 13 , wherein the configuration information reconfigures the selected gateway to perform in a different manner.
15. The method of claim 13 , wherein the configuration information assigns the selected gateway to report only utility consumption measuring devices it hears reliably with a signal strength over a threshold value.
16. The method of claim 13 , wherein the configuration information configures the selected gateway to operate within a Polling-Based Network.
17. The method of claim 13 , wherein the configuration information configures the selected gateway to operate within a Push-Based System.
18. The method of claim 13 , wherein the configuration information configures each of the selected gateways, previously configured to report data from a single utility consumption measuring device, to report data from all utility consumption measuring devices heard by the selected gateway.
19. The method of claim 13 , wherein the configuration information assigns the selected gateway to report data from a specific type of utility consumption measuring device.
