Signaling stack design for wireless ATM access networks

One of the challenges in designing a wireless ATM network is to specify con trol functions capable of managing data and signaling connections of moving mobile terminals. The challenge is tough, due to the facts that such contr ol functions neither exist in the current state-of-the-art wireless network s nor are included in the existing ATM specifications and implementations. This article describes the design principles of a wireless ATM signaling st ack created in the WAND project. The article identifies some common problem s and presents possible solutions to the problems. To justify the feasibili ty of the ideas presented, some details of a reference implementation, the WAND demonstrator signaling stack, will be revealed.
