A handoff method is provided between a mobile communication network including a packet data service node (PDSN), connected to a base station system (BSS), for supporting an Internet protocol (IP) routing function, and a wireless local area network (LAN) including an access router (AR) supporting the IP routing function. Upon detecting handoff to the wireless LAN, an access terminal (AT) with a contact set up to the PDSN exchanges a data packet with a correspondent node (CN) via a tunnel between the AR and the PDSN. The AT determines a user traffic state according to a transmission/reception state of the data packet, and changes the contact connected to the AT according to the user traffic state.
A handoff method between a mobile communication network including a packet data service node (PDSN), connected to a base station system (BSS), for supporting an Internet protocol (IP) routing function, and a wireless local area network (LAN) including an access router (AR) supporting the IP routing function, comprising the steps of:
A handoff method between a mobile communication network including a packet data service node (PDSN), connected to a base station system (BSS), for supporting an Internet protocol (IP) routing function, and a wireless local area network (LAN) including an access router (AR) supporting the IP routing function, comprising the steps of:
A handoff apparatus for an access terminal (AT) that moves from a mobile communication network including a packet data service node (PDSN), connected to a base station system (BSS), for supporting an Internet protocol (IP) routing function, to a wireless local area network (LAN) including an access router (AR) supporting the IP routing function, comprising:
A wireless communication system for performing handoff of an access terminal (AT) that moves from a mobile communication network including a packet data service node (PDSN), connected to a base station system (BSS), for supporting an Internet protocol (IP) routing function, to a wireless local area network (LAN) including an access router (AR) supporting the IP routing function, comprising:
