for Wireless ATM Networks

The introduction of wireless ATM (WATM) in customer premises networks (CPN) environ- m ents necessitates the design of mobility signaling protocols, since the existing versions of B- ISDN signaling do not support terminal mobility. Such protocols can be deployed either as ex- tensions to the standard signaling capabilities, or as individual solutions that have little or no impact on existing infrastructures (switches, signaling software, etc.). A WATM architecture that adopts the latter approach is presented. After a discussion on the problems encountered in the integration of wireless networking and B-ISDN ATM technologies, a Mobility Manage- ment and Control (MMC) protocol i s proposed. Finally, in the framework of the proposed MMC protocol, algorithms for implementing mobility procedures (handover and registration) are described.
