Abstract
If a hand-held terminal is connected to a single AP, the AP is provided from an administration server information of all the APs controlled by the administration server, transmits the information to the hand-held terminal, updates and stores it, and uses the updated and stored information of the APs to execute handoff. Basic lines and forwarding lines are disposed between all the APs and a private branch exchange, and a communication channel is formed using the basic lines to allow transferring the communication channel to the forwarding lines, thereby enabling to continuously perform a telephone communication session even if there is handoff during the telephone communication session using the hand-held terminal.
