Abstract

Collection of resource consumption data may be coordinated by designating, for each endpoint in a utility communication network, a single data collector to be responsible for reporting resource consumption data of the respective endpoints to a head-end computing device. If the head-end computing device does not receive resource consumption data from one or more endpoints, the head-end computing device may request the missing resource consumption data from one or more secondary or tertiary data collectors that receive resource consumption data from the one or more endpoints. Additionally, if a data collector is missing resource consumption data from an endpoint during a reporting period, upon receiving resource consumption data from the endpoint during a subsequent reporting period, the data collector may request the missing resource consumption data.

Claims

1. A data collector configured to collect resource consumption data from endpoints of a utility communication network for reporting to a head-end computing device of the utility communication network, the data collector comprising:

a processing unit comprising logic configured to implement acts comprising;

receiving from the head-end computing device a report list indicating that the data collector is a primary data collector for a subset of a plurality of endpoints of a utility communication network and is responsible for reporting resource consumption data of the subset to the head-end computing device;

receiving, from the subset of the plurality of endpoints and a plurality of endpoints other than the subset, communications reporting resource consumption data of the subset of the plurality of endpoints and the plurality of endpoints other than the subset;

storing resource consumption data in a memory of the data collector, wherein the stored resource consumption data distinguishes data received from the subset of the plurality of endpoints and data received from the plurality of endpoints other than the subset; and

reporting, to the head-end computing device, resource consumption data for the subset of the plurality of endpoints for which the report list indicates that the data collector is the primary data collector, while refraining from reporting resource consumption data to the head-end computing device received from the endpoints other than the subset of the plurality of endpoints and identified in the memory as data from secondary or tertiary endpoints with respect to the data collector.

2. The data collector of claim 1, wherein the subset of the plurality of endpoints for which the data collector reports resource consumption data to the head-end computing device comprises endpoints for which no other data collector in the utility communication network is configured to report resource consumption data.

3. The data collector of claim 1, wherein the subset of the plurality of endpoints for which the data collector is responsible for reporting resource consumption data to the head-end computing device comprises endpoints with which the data collector has a signal strength stronger than any other data collector in the utility communication network has with the respective endpoints.

4. The data collector of claim 1, the acts further comprising:

determining a signal strength of communications between the data collector and each endpoint of the plurality of endpoints; and

sending, to the head-end computing device, the determined signal strengths between the data collector and the plurality of endpoints;

the determined signal strengths being usable by the head-end computing device to generate the report list.

5. The data collector of claim 1, wherein the subset of the plurality of endpoints for which the data collector is responsible for reporting resource consumption data to the head-end computing device is based on:

signal strength of communications between the data collector and the plurality of endpoints; and

a load on the data collector relative to other proximate data collectors in the utility communication network.

6. The data collector of claim 1, wherein reporting resource consumption data to the head-end computing device for the subset of the plurality of endpoints comprises:

uploading, to the head-end computing device, at a first scheduled time during a reporting period, all resource consumption data of endpoints of the subset of the plurality of endpoints that has been received by the data collector for the reporting period as of the first scheduled time;

receiving, from the plurality of endpoints, additional communications including resource consumption data; and

uploading, to the head-end computing device, at a second scheduled time during the reporting period, all resource consumption data of endpoints of the subset of the plurality of endpoints that has been received by the data collector for the reporting period as of the second scheduled time and that has not previously been uploaded to the head-end computing device.

7. The data collector of claim 1, wherein reporting resource consumption data to the head-end computing device for the subset of the plurality of endpoints comprises automatically pushing the resource consumption data of the subset of the plurality of endpoints to the head-end computing device.

8. The data collector of claim 7, further comprising:

receiving, from the head-end computing device, a request for resource consumption data of an endpoint other than the subset of endpoints for which the data collector is responsible for reporting resource consumption data to the head-end computing device, and for which the data collector has received resource consumption data; and

uploading, to the head-end computing device, the requested resource consumption data for the endpoint.

9. The data collector of claim 7, wherein automatically pushing the resource consumption data of the subset of the plurality of endpoints to the head-end computing device, comprises automatically pushing at least a portion of the resource consumption data of the subset of the plurality of endpoints at multiple times scheduled substantially uniformly throughout a reporting period.

10. The data collector of claim 1, further comprising:

determining that the data collector did not receive resource consumption data, corresponding to a first reporting period, from a particular endpoint of the subset of endpoints for which the data collector is responsible for reporting resource consumption data to the head-end computing device;

receiving, from the particular endpoint, resource consumption data corresponding to a second reporting period subsequent to the first reporting period; and

sending a request to the particular endpoint, requesting that the particular endpoint provide the resource consumption data from the first reporting period.

11. A method comprising:

under control of a computing device of a utility head-end computing device configured with computer-executable instructions;

sending, to a first data collector, a first upload schedule that is stored in a memory of the first data collector indicating multiple times during a first reporting period at which the first data collector is to upload resource consumption data for a first plurality of endpoints for which the first data collector is responsible for providing resource consumption data;

sending, to a second data collector, a second upload schedule that is stored in a memory of the second data collector indicating multiple times during a second reporting period at which the second data collector is to upload resource consumption data for a second plurality of endpoints for which the second data collector is responsible for providing resource consumption data, wherein the second data collector is additionally directed to store, but not push to the utility head-end computing device, at least some of the resource consumption data for the first plurality of endpoints;

receiving, pushed from the first data collector, resource consumption data of the first plurality of endpoints for which the first data collector is responsible for providing resource consumption data in accordance with the first upload schedule;

receiving, pushed from the second data collector, resource consumption data of the second plurality of endpoints for which the second data collector is responsible for providing resource consumption data in accordance with the second upload schedule;

determining that the utility head-end computing device is missing resource consumption data of an endpoint for which the first data collector is a primary collector and is responsible for providing resource consumption data and for which the second data collector is a secondary data collector; and

requesting, from the second data collector, the missing resource consumption data of the endpoint, which was previously stored by the second data collector, but not pushed by the second data collector to the head-end computing device.

12. The method of claim 11, further comprising receiving, from the second data collector, the missing resource consumption data of the endpoint.

13. The method of claim 11, further comprising requesting, from a third data collector, the missing resource consumption data of the endpoint.

14. The method of claim 11, wherein the first plurality of endpoints and the second plurality of endpoints are mutually exclusive, but the first data collector and the second data collector both receive resource consumption data from at least one common endpoint.

15. The method of claim 11, further comprising, prior to receiving resource consumption data pushed from the first and second data collectors:

sending, to the first data collector, a first report list indicating the first plurality of endpoints for which the first data collector is responsible for reporting resource consumption data to the head-end computing device; and

sending, to the second data collector, a second report list indicating the second plurality of endpoints for which the second data collector is responsible for reporting resource consumption data to the head-end computing device.
