Abstract
A cell flow synchronization establishing system of an ATM access system, capable of establishing synchronization of cell flow between a mobile station and base stations at the time of hand-off process, is provided. First buffer control unit is provided in the ATM switching station, and second buffer control unit is provided in the mobile station. The first buffer control unit reproduces cell stream to be transmitted by guaranteeing orderness of ATM cell between the first buffer control unit and the second buffer control unit and buffer clear processing is carried out based on predetermined synchronization establishment processing sequence before and after occurrence of handoff.
