1. A network manager (NM) comprising:

  • a self-optimized network (SON) coordination function to prevent a conflict and to provide resolution to the conflict cause by an operation of one SON function at the same time when another SON function is to operate on an enhanced Node B (eNodeB) of a plurality of enhanced node Bs (eNodeBs);

    wherein, the SON coordination function is to coordinate SON functions which include at least an energy saving management (ESM) function, a cell outage compensation (COC) function or a coverage and a capacity optimizing (CCO) function based on a SON coordination state, the SON coordination state being a state of SON functions, wherein the SON coordination state is one ofa first state indicating that a respective eNodeB of the plurality of eNodeBs is already providing coverage for other eNodeBs of the plurality of eNodeBs that are switched off for energy-saving purposes by an ESM SON function,a second state indicating that a respective eNodeB of the plurality of eNodeBs is already providing coverage of a neighboring eNodeB that is in outage, anda third state indicating that a respective eNodeB of the plurality of eNodeBs is updating the configuration parameters in a respective cell.
