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.

Abstract: A femto base station of a WiMAX system can manage a list of closed subscriber groups (CSGs). A CSG indicator is broadcast. The femto base station receives a registration request message from a mobile station having received the CSG indicator and adds the mobile station to a CSG registration list. The femto base station searches for the mobile station from the CSG registration list if an attach request message is received; and forwards the attach request message to an access service network (ASN) gateway if the mobile station is in the CSG registration list. The femto base station establishes a link message with the mobile station if an attach acceptance message corresponding to the attach request message from the ASN-gateway.

Abstract: When a terminal moves from a WLAN network to a cellular network after being allocated an IP address from a PDSN of the cellular network, a tightly coupled interworking method and apparatus between the cellular network and the WLAN network set up a temporary tunnel between the PDSN and an AGW of the WLAN network, and after completion of the handoff from the WLAN network to the cellular network, inform the PDSN of the handoff completion from the terminal, thereby enabling fast seamless handoff without data loss. Compared with the conventional tightly coupled scheme, the proposed tightly coupled scheme can prevent the need for processing cellular signals in the WLAN network because there is no need to transmit cellular signals in a WLAN interval, especially between the terminal and the AGW.
