Optimizing Voice in ATM/IP Mobile Networks

* UMTS network scenarios
* Strategies for integrating 3G traffic with PSTN access
* Engineering guidelines for maintaining voice QoS by wisely choosing CLR targets, overbooking, and buffer sizings

PROVEN METHODS

Based on the author’s own involvement with the design of successful large-scale voice networks and the original research she has undertaken, Juliet Bates’ Optimizing Voice in ATM/IP Mobile Networks presents advanced approaches to the challenges engineers face in transmitting voice services over broadband networks. This book helps readers:

* Compare ATM Adaptation layer choices for mobile 2G / 3G and PSTN / PBX voice access
* Carry out effective mathematical modeling with algorithms for multiplexed conversational voice
* Understand delay and bandwidth requirements of compression coders
* Expand capacity within stringent Quality of Service constraints
* Know when to trade a lower CLR for reduced bandwidth
* Reduce delay in the buffer queue
* Overbook multiple channels according to a selected CLR target
* Tune the traffic descriptors for the Call Admission Control Algorithm
* Keep up with the progress of competitive voice technologies
