Abstract
A wireless communication system for asynchronous transfer mode includes the dynamic mapping of ATM cells on a wireless ATM link into a unique Virtual Path on a wired ATM link, and in the reverse direction as well. The access point includes a radio medium access controller which assigns a unique radio connection identifier RCI to the wireless link established between the access point and a mobile terminal. The Virtual Path identifier (VPI) used on the fixed link is selected based on the RCI assigned by the access point. The radio connection identifier RCI remains unchanged as long as the mobile terminal is associated with that access point. ATM cells sent from the control function include the VPI and are mapped by the access point into the connection referenced by the RCI. ATM cells from the mobile terminal are received on a particular connection. According to the connection identifier (RCI) cells are mapped by the access point into a particular Virtual Path, which corresponds to the RCI.
