Nokia has launched iSON Manager, a centralized Self Organizing Networks (SON) solution for the automation of multi-vendor heterogeneous networks. The solution aims to provide many new capabilities to improve network efficiency. According to Nokia Networks, the solution which has been used during pre-launched trial in a live network with KT, helped reduce the Korean operator’s LTE radio network energy consumption by 40%. The company added that the newly launched iSON Manager that uses advanced analytics to improve network performance in real time, comes with more than 20 off-the-shelf centralized functional packages with full coordination capabilities for automated configuration, optimization and healing of multi-vendor mobile broadband networks. This complements the distributed automation functions already built into the network elements.
