WE CLAIM:
1. An apparatus (400) to be employed in an evolved nodeB (eNB) (12), the apparatus
comprising:
one or more processors (404) operably coupled with one or more non-transitory computer readable media, the one or more processors are to execute instructions to implement a plurality of self-organizing network (SON) functions, wherein each SON function of the plurality of SON functions comprises SON coordination functionality to coordinate configuration parameter changes among the plurality of SON functions, and wherein, to operate the SON coordination functionality of an energy savings management (ESM) function of the plurality of SON functions, the one or more processors are to execute the instructions to:
identify a trigger for the eNB to enter an energy savings (ES) compensation state
to compensate for a cell provided by another eNB that is to enter an energy saving (ES)
state;
determine whether one or more configuration parameters are currently being
changed for the eNB by a SON function of the plurality of SON functions other than the
ESM function; and
instruct the eNB to initiate the ES compensation state when the one or more
configuration parameters are not currently being changed by the SON function other
than the ESM function.
2. The apparatus of claim 1, wherein the one or more processors are to execute the
instructions to:
instruct the eNB to not initiate the ES compensation state based on a determination that the one or more configuration parameters are currently being changed.
3. The apparatus of claim 1, wherein, to instruct the eNB to initiate the ES
compensation state, the one or more processors are to execute the instructions to:
instruct the eNB to adjust a configuration parameter of the one or more configuration parameters.

4. The apparatus of claim 1, wherein the eNB is to be triggered by the ESM function to compensate the other eNB at off-peak times to provide coverage to accommodate powering down of the other eNB.
5. The apparatus of claim 1, wherein the SON function other than the ESM function is a capacity and coverage optimization (CCO) function.
6. The apparatus of claim 1, wherein the one or more configuration parameters include one or more of a downlink transmission power, an antenna tilt, or an antenna azimuth.
7. A computer-implemented method comprising:
implementing a plurality of self-organizing network (SON) functions, wherein each SON function of the plurality of SON functions comprises SON coordination functionality to coordinate configuration parameter changes among the plurality of SON functions, and wherein, to operate the SON coordination functionality of an energy savings management (ESM) function of the plurality of SON functions;
determining whether an evolved nodeB (eNB) (12) is to be activated to compensate for another eNB that is to enter an energy saving (ES) state;
determining whether one or more configuration parameters are currently being changed for the eNB by a capacity and coverage optimization (CCO) function, wherein the CCO function is among the plurality of SON functions;
instructing the eNB to not initiate an ES compensate state when it is determined that the one or more configuration parameters are being changed by the CCO function such that the eNB will not compensate for the other eNB that is to enter the ES state.
8. The computer-implemented method of claim 7, further comprising:
instructing the eNB to initiate the ES compensate state when it is determined that the one or more configuration parameters are not being changed by the CCO function such that the eNB will compensate for the other eNB after the other eNB enters the ES state.

9. The computer-implemented method of claim 8, wherein instructing the eNB to
initiate the ES compensate state comprises:
instructing the eNB to adjust a configuration parameter of the one or more configuration parameters.
10. The computer-implemented method of claim 7, wherein the eNB is to be activated
to compensate the cell that is to enter ES state by an ES function, and the method further
comprises:
determining whether the eNB is currently in an ES state; and
refraining from instructing the eNB to initiate the ES compensate state when it is determined that the eNB is currently in the ES state.
11. The computer-implemented method of claim 7, wherein the one or more
configuration parameters include one or more of a downlink transmission power, an antenna
tilt, or an antenna azimuth.
12. The computer-implemented method of claim 7, wherein determining whether the
one or more configuration parameters are being changed by the CCO function comprises:
testing a semaphore to determine whether the semaphore is in a locked state; and setting the semaphore to the locked state when it is determined that the semaphore is not in the locked state.
13. An apparatus (400) to be employed as an evolved nodeB (eNB) (12), the apparatus
comprising:
a processor (404) operably coupled with a memory (408, 410, 412), wherein the processor is to operate one or more self-organizing network (SON) functions including a capacity and coverage optimization (CCO) function, wherein each SON function of the one or more SON functions comprises SON coordination functionality to coordinate configuration parameter changes among the one or more SON functions, wherein, to operate the SON coordination functionality of the CCO function, the processor is to execute instructions to:

detect an event that triggers the eNB to perform a CCO procedure for a cell (14) provided by the eNB, determine whether one or more configuration parameters are currently being changed for the eNB by a SON function of the one or more SON functions that is different than the CCO function in response to the detection, and
instruct the eNB to initiate performance of the CCO procedure based on a determination that the one or more configuration parameters are not currently being changed by the SON function that is different than the CCO function.
14. The apparatus of claim 13, wherein the processor is to execute the instructions to instruct the eNB to not initiate performance of the CCO procedure based on a determination that the one or more configuration parameters are currently being changed.
15. The apparatus of claim 13, wherein the processor is to execute the instructions to instruct the eNB to adjust configuration parameter of the one or more configuration parameters.
16. The apparatus of claim 14, wherein the SON function other than the CCO function is an energy savings management (ESM) function among the one or more SON functions.
17. The apparatus of claim 13, wherein the one or more configuration parameters include one or more of a downlink transmission power, an antenna tilt, or an antenna azimuth.
