英文摘要：

The ultra dense deployment and the coexistence of multi-system networks make the fifth generation （5G） mobile communications ultra-dense network operation complexity and cost increase greatly. Network self-organization has been as a key technology in 5G ultra-dense network for its excellent performance on enhancing the network management efficiency and reducing the operating costs. The network self-organization technology and its function,such as self-configuration, self-optimization and self-healing were introduced. Moreover, the technology challenges and the trends were analyzed for further research.
