Abstract
The present specification suggests a method and an apparatus for more efficient mobility management through a hierarchical structure of a micro mobility management entity (MME) and a macro MME in a mobile communication system. Particularly, a second MME establishes a connection with a plurality of small cells included in a single macro cell. The second MME manages a single particular macro cell, and a first MME manages a plurality of macro cells, thereby providing a hierarchical structure. Additionally, the second MME transmits a paging message to a small cell in which a terminal is positioned, among the plurality of small cells included in a single macro cell. The second MME has information on the position of the terminal and can transmit the paging message to a particular small cell in which the terminal is positioned.
