Number of sons management in a cell network
View Patent ↗The present technology relates to protocols relative to utility meters associated with an open operational framework. More particularly, the present subject matter relates to protocol subject matter for advanced metering infrastructure, adaptable to various international standards, while economically supporting a 2-way mesh network solution in a wireless environment, such as for operating in a residential electricity meter field. The present subject matter supports meters within an ANSI standard C12.22/C12.19 system while economically supporting a 2-way mesh network solution in a wireless environment, such as for operating in a residential electricity meter field, all to permit cell-based adaptive insertion of C12.22 meters within an open framework. Cell isolation is provided through quasi-orthogonal sequences in a frequency hopping network. Additional features relate to apparatus and methodology subject matters relating to Number-of-sons' management.
1. A metrology device for use with an advanced metering system mesh network having adaptive neighborhood management of communications links, and having a central facility, a plurality of node devices, with at least some of such node devices comprising such metrology devices, and at least some of such node devices comprising father node devices providing synchronized communications links for others of the node devices defining son node devices of a given respective father node device, with each node device configured for bi-directional communications with such central facility via associations with respective of the father node devices, said metrology device comprising:
a metrology portion configured to measure consumption of a utility commodity;
a transmitter portion configured to transmit consumption information from its associated metrology portion and other data;
and a receiver portion configured to receive information from other network devices in an associated network;
wherein said metrology device portion is configured for providing to its respective father node device on an associated network information about alternative father communications links available to such metrology device in such associated network, so that such respective father node device may make determinations about removing such metrology device as a son thereof in lieu of other node devices on such associated network.
2. A metrology device as in claim 1 , wherein said metrology device portion is further configured for including in transmissions from said metrology device a flag notification indicating whether such metrology device has available to it potential fathers above a predetermined number thereof.
3. A metrology device as in claim 2 , wherein said metrology device portion is further configured such that transmitting such flag notification comprises including a set bit in a message format of transmissions from such metrology device.
4. A metrology device as in claim 1 , wherein said metrology device portion is further configured for responding to a removal notification from its respective father node device of an associated network by thereafter reacquiring synchronization with one of its available alternative father communications links.
