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.

AbstractNext-generation mobile technologies are the enablers for meeting the variable specific requirements of the public safety (PS) community. In particular, due to the development of commercially deployed 5G networks, PS providers look for ways to implement related solutions upon such infrastructures, potentially in a shared use with existing commercial networks. In particular, LTE and 5G NR networks are rapidly gaining recognition as an all-inclusive critical communications platform for the delivery of both mission and business critical applications. Within this scope, we take into account the innovative architectural approach that has been proposed by the 5G ESSENCE project, addressing the paradigms of edge computing and small cell as-a-service that has been realised via a cloud-enabled small cell infrastructure leveraging multi-access technologies in 5G, where we propose a dedicated PS use case, able to offer a mission critical push-to-talk service as well as a Chat and Localisation service. Each one of these services is associated to a dedicated network slice within the scope of the corresponding fundamental 5G ESSENCE architecture and both services are provided via suitable VNFs, thus offering great flexibility to serve PS needs together. We further discuss the overall scenario deployment with the related technical enablers and the proposed functionalities, per case. The corresponding end-to-end slicing makes possible to allocate both radio and cloud resources to the involved critical actors, in an automated and elastic way.

The Way

The development of cellular wireless systems has entered the phase when 5G networks are being deployed and the foundations of 6G solutions are being identified. However, in parallel to this, another technological breakthrough is observed, as the concept of open radio access networks is coming into play. Together with advancing network virtualization and programmability, this may reshape the way the functionalities and services related to radio access are designed, leading to modular and flexible implementations. This paper overviews the idea of open radio access networks and presents ongoing O-RAN Alliance standardization activities in this context. The whole analysis is supported by a study of the traffic steering use case implemented in a modular way, following the open networking approach.
