Self-organizing Networks is a key driver for improving automated management in 4G and 5G networks. It reduces installation and management cost through simplifying operation task by self-configuration, optimization and healing of the network. In this context, load balancing, capacity optimization and mobility robustness optimization are examples of SON tools to improve network performance. As those tools achieve their function by adjusting the same parameters, a conflict is induced with these performance metrics. In this paper, we address the conflict resolution problem resulted from automated management of SON for different performance metrics. In addition we provide a novel solution for concurrent optimization of capacity and robustness while maintaining load imbalance between cells to its minimum value. The proposed solution is compared against two benchmark schemes to further illustrate the improvement of network performance with SON proposed algorithm in terms of throughput, robustness, and load distribution.
