1. A computer-implemented dynamic power control management (DPCM) method for a base station, the method comprising:

  • collaborating with a plurality of components operating on at least one core of a multi-core processor to periodically obtain information for a plurality of cells supported by a base station over a specified interval, wherein the information comprises at least a call load, an uplink data rate, and a downlink data rate for the cells, and wherein the multi-core processor comprises a plurality of processor cores configured under a single symmetric multiprocessing partition and served by a single operating system instance that serves a shared control plane core and N cell specific data plane cores, where N is the number of configured cells on the base station;

    using the information obtained from the components to determine if individual cells are operating at or below a threshold off-peak capacity over the specified interval;

    using the information obtained from the components to determine if the base station is operating at or below a threshold off-leak capacity, over the specified interval;

    implementing a plurality of state machines comprising a first type state machine and a second type state machine, wherein the first type state machine is configured to manipulate a processor core frequency of a respective one of the cell specific data plane cores and the second type state machine is configured to manipulate a processor core frequency of the shared data plane core used by the configured cells on the base station;

    asynchronously sending at least one state transition trigger to a DCPM module for a first of the first type state machines wherein the at least one state transition trigger is based at least upon a first threshold determination for a first of the configured cells;

    asynchronously sending at least one state transition trigger to a DCPM module for the second type state machine, wherein the at least one state transition trigger is based at least upon the threshold determination for the cumulative base station.
