Abstract EN
An attractive architecture called heterogeneous cloud radio access networks (H-CRAN) becomes one of the important components of 5G networks, which can provide ubiquitous high-bandwidth services with flexible network construction.
However, massive access nodes increase the risk of cell outages, leading to negative impact on user-perceived QoS (Quality of Service) and QoE (Quality of Experience).
Thus, cell outage management (COM) became a key function proposed in SON (Self-Organized Networks) use cases.
Based on COM, cell outage detection (COD) will be resolved before cell outage compensation (COC).
Currently few studies concentrate on COD for 5G H-CRAN, and we propose self-organized COD architecture and approach for it.
We firstly summarize current COD solutions for LTE/LTE-A HetNets and then introduce self-organized architecture and approach suitable for H-CRAN, which includes COD architecture and procedures, and corresponding key technologies for it.
Based on the architecture, we take a use case with handover data analysis using modified LOF (Local Outlier Factor) detection approach to detect outage for different kinds of cells in H-CRAN.
Results show that the proposed approach can identify the outage cell effectively.
