PURPOSE: A direct communication method between terminals connected with an indoor base station and indoor base station thereof are provided to offer direct communication between LTE(Long Term Evolution) terminals connected with the indoor base station without changing a core network. CONSTITUTION: In case an IP(Internet Protocol) address of a reception terminal is not included in the UE-DB(User Equipment Data Base) of an indoor base station, a control unit transmits IP packets through a normal user traffic processing procedure(S406,S408). The IP address of the reception terminal includes the UE-DB, the control unit transmits the IP packets to a PDCP(Packet Data Convergence Protocol) layer in order to transmit the IP packets to the reception terminal(S410).
