Abstract

This work uses the mobile network operators’ knowledge regarding mobile subscriber movement in the current infrastructure, i.e., Decentralized Radio Access Network (D-RAN), to dimension the infrastructure needed for the new generation of mobile infrastructure, i.e., Cloud/Centralized Radio Access Network (C-RAN). We propose a heuristic considering two approaches, one focused on the coverage of users and another focusing on the aggregated throughput. The performance assessment considers that the day is divided into three periods: working hours (morning), leisure hours (afternoon) and home hours (night). Results show that the heuristic allows mobile network operators to properly dimension the number of Small Cells (SCs) needed for a given area, maximizing the multiplexing and efficiency of the BaseBand Units (BBUs).
