A mobility management control method and system that can redress the uneven loads on base stations in a mobile communications network are provided. Multiple base stations in a tracking area each have a mobile station mobility management function. A base station positioned at an edge of the tracking area monitors its own load state. Depending on its own load state, the base station relocates to another base station a location management function with respect to a new location management request, or a location management function as a mobility management serving base station with which location management has been already performed for a mobile station.
