The concept of self-organising networks (SONs) – automating key network processes – is heralded as an inevitable part of next generation LTE network architecture. SONs were created to reduce and create more efficient network operations, driving opex and capex reductions.
This white paper discusses a model of the likely benefits that can be realised in a realistic network. In the base model, the operator introduces SON features (in a hybrid architecture) in both UMTS and LTE over a period of three years, while LTE is minimally deployed and UMTS capacity augmentation primarily meets the increasing data needs.
The paper also outlines the additional benefits that can be gained through an aggressive LTE roll-out.
