Abstract: A method and an apparatus for providing a Local BreakOut (LBO) service in a wireless communication system are provided. In the method for providing an LBO service in a wireless communication system, after an access authentication procedure between an authentication server and a terminal, a femto gateway receives a subscriber profile including LBO service flow information from the authentication server to provide the LBO service flow information to a femto base station through initial service flow setting between the terminal and the femto gateway. The femto base station sets an LBO service flow through a Dynamic Service Addition (DSA) procedure. The terminal performs a Dynamic Host Configuration Protocol (DHCP) procedure through the LBO service flow setting, and obtains an IP address for LBO based on the DHCP procedure.
