A Novel Model for Multilayer GSM Network Design

Summary GSM Network Designs usually offers big challenges for achieving an efficient cost while respecting the complex combinatorial technical constraints. This networks have hundreds or thousands BTS (Base Transceiver Station). They have their traffic grouped in hubs, then in BSC (Base Station Controller) nodes to reach the MSC. Hubs must be elected within the BTS set and BSC nodes have to be geographically allocated in the available sites. Also, the number and model of these BSC impact in the overall cost while the distances affect the transmission costs. This paper presents a mathematical model for designing a GSM network from the BTS lower layer until the MSC layer.
