Abstract
A method for performing a handoff between a wireless local area network (LAN) including an access router (AR) supporting an Internet protocol (IP) routing function and a mobile communication network including a packet data service node (PDSN) connected to a base station system (BSS), for supporting the IP routing function. An access terminal (AT) detects its movement from the wireless LAN to the mobile communication network, and exchanges information for tunneling between the AR and the PDSN, with the PDSN. The PDSN sets up a tunnel for packet delivery between the PDSN and the AR, and delivers packets to the AT through the set tunnel.
