Design of the ATM‐based interconnecting network of the access segment of future cellular systems

An important issue in future cellular communication systems is the design of the interconnecting network of their access segment. This problem aims at finding the minimum‐cost configuration of cell site switches (CSSs) and local exchanges (LEs) given the base transceiver station (BTS) layout. An extended version of the problem may also comprise the deployment of mobility and service control points‐access (MSCPs‐A), based on the assumption that CSSs and LEs are not fully capable of handling the logic of the cellular system. In this paper we solve the extended problem, under the additional assumption that the communication among the network elements is based on the ATM technique. The problem is formally defined, optimally formulated, and solved by computationally efficient heuristics. Finally, results are provided and subsequent conclusions are drawn.
