In this paper we propose a model for the expansion problem of the network subsystem of a universal mobile telecommunication system wireless cellular network considering an update in the base station subsystem. The objective is to minimize the expanison cost of the network subsystem while considering network performance (e.g., call and handover blocking). Since the network expansion problem is a generalization of the design problem, the proposed model can also be used for designing networks. In order to find good solutions, we propose a heuristic based on the tabu search principle. Finally, we present a performance analysis of the proposed heuristic. The analysis shows that quasi-optimal solutions are found with the proposed heuristic.
