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)
—This paper addresses handoff management in a mul-tifrequency 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 inter-cell hard handoffs, not only incurring equipment cost burden but also degrading call quality, are totally removed.
