This paper addresses handoff management in a multifrequency code-division multiple-access system with nonuniform traffic loads over cells. We propose a new handoff scheme, called here adaptive handoff management (AHM), in which the intercell hard handoffs, not only incurring equipment cost burden but also degrading call quality, are totally removed.

This study deals with the access network design problem in universal mobile telecommunication systems (UMTS) networks. We provide a mathematical formulation of the problem with constraints on RNC and node-B capacities, along with a lower bounding method. We also develop a heuristic algorithm with two different initial solution methods designed to strengthen(More)
