This paper studies handoff control mechanisms based on a `mobile ATM' concept. Mobile ATM refers to an ATM infrastructure which supports ubiquitous mobile services through extending ATM signaling functions within the ATM backbone. In order to meet the performance criteria required by a diverse set of mobile services, we propose a unified handoff control protocol which is independent of wireless access technologies (ATM/nonATM) and path rerouting algorithms. Such a protocol can provide (1) a common software architecture for system implementation, (2) a common measurement base for performance evaluation and (3) a common signaling syntax for standardization. A prototype system is implemented based on this protocol, which provides an IP-over-ATM service with WaveLAN access
