The development of cellular technology will be directly proportional to the increasing requirement in various aspects, such as the speed of data transmission (velocity), data variations (variety), and data storage media (volume). The increase in various aspects will have a direct impact on the growth of internet users worldwide. In relation to that, the demand for increased capacity and coverage becomes a necessity because users access the networks using the same resources by utilizing resource sharing mechanism. Self Organizing Network (SON) is one of the solutions to make the system more efficient with guaranteed Quality of Experiment (QoE). SON can create an automated network with a self-optimization, self-configuration and self-healing mechanism. Big Data is leveraged in the network analytics as a reference for decision-making activities in the network automation process. In this paper, SON using Big Data analytics on 5G network is compared with SON on 4G network as the previous network technology. It is suggested that on 5G networks, Big Data changes the SON detection paradigm from reactive to proactive. Detecting problems starts with data collection and analysis of possible network problems. By predicting network problems early, solving network problems can be done faster. Additionally, by using Multi-hop relay, the distance between User Equipment (EU) and Base Station (BS) will be shorter. Therefore, the aim of increasing capacity and coverage can be fulfilled.
Hybrid Self-Organizing Networks: Evolution, Standardization Trends, and a 6G Architecture Vision
自组织网络需要具有自协调能力，以管理其内部组件之间的复杂关系，并避免其破坏性的相互作用。现有的通信技术通常实现在动态情况下可能非常缓慢的响应自协调机制。第六代（6 G）网络正处于研究和标准化活动的早期阶段，为在开发自协调能力时选择设计驱动的方法提供了新的机会。这可以通过使用混合SON设计来实现。混合体系结构结合了集中式和分布式的管理和控制。在这篇文章中，我们回顾了SONs的历史，包括固有的自我协调功能。然后，我们深入研究了混合SON（H-SON）的概念，并总结了H-SON发展的挑战，机遇和未来趋势。我们提供了一个全面的标准化活动和建议的集合，讨论了继续发展和推动H-SON范式广泛采用的关键贡献和潜在工作。更重要的是，作为一个关键的6 G架构特征，我们建议H-SON应该是松散耦合的网络。松耦合是指不同层的弱交互和同一层用户之间的弱交互，即，各种反馈回路必须几乎彼此隔离，以提高稳定性并避免混乱情况。最后，我们总结了关于未来前景和6 G H-SONs关键驱动因素的关键提示。
