    摘要： 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.

    摘要： An apparatus and method are provided for changing network interfaces in a multiaccess mobile terminal in a wireless communication system including a server for providing high-capacity data transmission service to a mobile terminal, and the terminal for receiving data from the server and supporting various network interfaces. Upon detecting handoff based on current air information received, an interface module reports a change in interface to a new air interface to an upper layer, and manages the mobile terminal such that traffic is transmitted to the new air interface. Upon receiving information on the new air interface from the interface module, a service module determines a bandwidth of the new air interface, generates a message based on the determined bandwidth, and transmits the generated message.

    摘要： 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.
