FIELD: wireless communication equipment.
SUBSTANCE: group of inventions relates to the field of wireless communication systems. Network manager (NM) includes the self-optimizing network (SON) coordinating function to avoid conflict and to enable the conflict resolution caused by the one SON function operation simultaneously with that, when another SON function should operate on the extended node B (eNodeB). SON function coordination is configured to coordinate SON functions, including at least an energy saving management (ESM) function, cell operation standstill (COS) compensation function, or a service area optimization and bandwidth optimization function, based on the SON coordination state. SON coordination state is one of the following states: the first state indicating that the corresponding eNodeB is already providing a coverage area for the other eNodeBs turned off to save power by the SON ESM function; second state indicating that the corresponding eNodeB is already providing a coverage area for a neighboring eNodeB that is in the standstill state; and the third state indicating that the corresponding eNodeB is updating the configuration parameters in the corresponding cell.
EFFECT: technical result is in elimination of the conflicts with change in the eNodeB configuration parameters.
