Abstract

Packet formats and related infrastructure for improved messaging and processing of commands in an AMR system are disclosed. In one embodiment, a method for identifying the features of an endpoint based on data encoded in a standard meter reading is provided. In this regard, the method includes receiving a standard meter reading having an endpoint type and subtype classification, wherein the subtype classification corresponds to a feature of the endpoint that may be re-configured. Once received, the standard metering reading is decoded. Then, the method identifies the classification of the endpoint with regard to type and subtype and determines whether the endpoint is capable of implementing a particular command.

Claims

1. A method of identifying the features of an endpoint having a packet creation interface, based on data encoded in a standard meter reading, the method comprising:

receiving an interface call at the packet creation interface, the call having parameters that identify a current consumption value and that identify a pointer referencing a buffer memory space for temporary storage of packet data;

accepting an existing buffer memory space having a protocol ID value corresponding to a process for decoding the packet and a type/subtype value for classifying at least one feature of the endpoint;

receiving a standard meter reading from the endpoint, having an endpoint type and subtype classification, the subtype classification corresponding to a capability of the endpoint that may be re-configured;

decoding the standard metering reading; and

identifying a type and subtype classification of the endpoint to determine whether the endpoint is capable of implementing an issued command.

2. A method as in claim 1, further including retrieving one or more data items for temporary storage in the buffer memory space, the one or more data items including serial number that uniquely identifies the associated endpoint.

3. A method as in claim 2, further including returning the pointer to the buffer memory space.

4. A method as in claim 1, wherein determining whether the endpoint is capable of implementing an issued command comprises determining whether the endpoint is limited to simplex communications.

5. A method as in claim 1, further comprising categorizing the standard meter reading to determine an appropriate method to decode standard meter reading.

6. A method as in claim 5, wherein categorizing comprises reading a protocol ID field within the standard meter reading.

7. A method as in claim 1, further including providing a collection system configured to forward meter readings to a host computing system of a utility service provider over a wide area network (WAN).

8. A method as in claim 7, wherein said WAN is implemented utilizing at least one of TCP/IP Protocols, GPRS or other cellular-based protocols, Ethernet, WiFi, Broadband, and Over Power Line communications.

9. A method as in claim 1, wherein the endpoint includes a main computing device communicatively coupled with a communications device.

10. A method as in claim 9, wherein the communications device is one of a radio-based transceiver and transmitter-receiver devices having respective transmit and receive circuitry switched to an antenna during respective operations thereof.

11. A method as in claim 9, wherein the communications device is configured to transmit RF-based communications signals according to at least one of modulation protocols including DSSS, FHSS, AM, and FM.
