Call admission control issues in a wireless ATM network

This paper presents call admission control issues for an ATM-based wireless network with mobile hosts. Such wireless ATM networks are motivated by both an increasing demand for mobile capability for future broadband networks and broadband multimedia services for mobile systems. An ATM compatible wireless network capable of supporting a mix of broadband ISDN services is discussed. We present a conceptual view of a wireless ATM architecture with distributed call admission functions. Related issues of call admission control caused by these characteristics are discussed, and new trends toward call admission control in future wireless ATM network are identified.
