Access signaling and IN-based mobility management for wireless ATM systems

Abstract

This paper focuses on the design of signaling and mobility control protocols for wireless ATM (W-ATM) systems based on the intelligent network (IN) concepts. The employed signaling protocol architecture aims for private W-ATM networks to access the core B-ISDN/ATM infrastructure. The proposed design intents to minimize the changes required to the wired ATM network signaling to accommodate mobility features, by taking advantage of the well-developed capability sets. A signaling performance evaluation is carried out to demonstrate the impact of the proposed signaling architecture onto various performance measures and to identify the behavior of the system under various signaling loads in order to reveal the limits of the signaling system stability.
