Abstract: Wireless ATM (WATM) will be used to support broadband multimedia services. To achieve this, the existing ATM protocol must be augmented with mobility function. Handover is one of important function of mobility management in the WATM system. This paper describes a handover mechanism for intra-switch handovers in the wireless ATM. On the other hand, this paper present a simple signaling and control architecture for mobility support in a wireless ATM network that provides integrated multimedia services to mobile terminals. !4
