Method and apparatus for providing local breakout service in wireless communication system

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.

1. A method for operating a femto gateway to provide a Local BreakOut (LBO) service in a wireless communication system, the method comprising:
after an access authentication process between an authentication server and a terminal, receiving a subscriber profile comprising LBO service flow information from the authentication server; after establishing an initial service flow between the terminal and the femto gateway, providing the LBO service flow information to a femto base station; and receiving information informing that an LBO service flow has been successfully established from the femto base station, wherein the femto base station distributes LBO traffic of the terminal via an LBO path established between the femto base station and an Internet network through an Internet Service Provider (ISP) network using a second Internet Protocol (IP) address, and distributes data traffic of the terminal via a data traffic path established between the femto base station and the Internet network through the ISP network and the femto gateway using a first IP address, and wherein the femto base station supports a direct connection between the terminal and another terminal serviced by the femto base station without detouring via the Internet network, wherein the first IP address is obtained from a Dynamic Host Configuration Protocol (DHCP) server of the femto gateway, and wherein the second IP address is obtained from a DHCP server of the femto base station.
