Abstract

A process for communicating utility-related data over at least one network is described. the process includes: collecting utility-related data at a hub device during a first predetermined period of time; securing the utility-related data at the hub device using digital envelopes during the first predetermined period of time; initiating by the hub device an autonomous wake up process during a second predetermined period of time; sending the secure utility-related data over a first network to a designated server via at least one User Datagram protocol (“UDP”) message during the second predetermined period of time; and receiving an acknowledgement of receipt message of the at least one UDP message from the designated server; wherein the first and second predetermined periods of time typically do not overlap, but may overlap.

Claims

1. A computer-implemented method for receiving utility-related data over a network comprising:

receiving at a head end device, a User Datagram protocol (UDP) bulk message comprising one or more UDP messages in a digital envelope, where each of the one or more UDP messages includes utility-related data, wherein utility-related data includes one or more of utility meter reading data, utility meter alarm data and firmware upgrade status data;

validating the digital envelope;

sorting the UDP messages; and

transmitting a second UDP message comprising an acknowledgement of receipt for each of the received UDP messages, wherein each of the one or more received UDP messages comprises in a first part of the UDP message, a reason code for facilitating the sorting of the one or more UDP message into one of multiple predetermined storage buckets, and in a second part of the one or more UDP message, the utility-related data.

2. The computer-implemented method of claim 1, wherein the predetermined storage buckets include at least two of an electricity usage message bucket, a gas usage message bucket, an electricity generation message bucket, and an alarm message bucket.

3. The computer-implemented method of claim 1, wherein first part of the one or more UDP messages is secured with integrity protection, and wherein the second part of the one or more UDP messages is secured with both integrity protection and privacy encryption.

4. The computer-implemented method of claim 1, wherein the transmitted UDP message comprising the acknowledgement of receipt messages includes clock synchronization information.

5. The computer-implemented method of claim 1, wherein the acknowledgement of receipt messages are encoded in the UDP message.
