transmitting a configuration information response message to the network element corresponding to the configuration information request message,
wherein the time zone information comprises a list of a plurality of different time zones, a maintenance period corresponding to each of the time zones, and information on NEs disposed in each of the time zones,
wherein the information on the NEs comprises the number of NEs in which reset is required among NEs disposed in each of the time zones,
wherein generating a network element (NE) list comprises determining a reset rate corresponding to each of the time zones based on the maintenance period and the number of NEs in which reset is required,
wherein generating a network element (NE) list further comprises determining a reset completion rate of each of the time zones based on information on the NEs and the maintenance period,
wherein the reset completion rate indicates a ratio of network elements capable of completing reset within the maintenance period among serviceable network elements disposed in each of the time zones,
