Operational Troubleshooting-Enabled Coordination in Self-Organizing Networks
نویسندگان
چکیده
A Self-Organizing Network (SON) performs automated network management through the coordinated execution of autonomous functions, each aiming to achieve a specific objective like the optimization of a network Key Performance Indicator (KPI) value. However, there are situations in which a SON function cannot achieve its objective which can lead to disturbed SON operation and inferior performance. We present a SON Operational Troubleshooting (SONOT) SON function that is able to detect such problematic situations and trigger respective countermeasures. Thereby, it can exploit regular SON functions as probes in order to improve problem detection. Simulations show that the tight integration of the SONOT function with SON coordination provides means to automatically overcome the problems and improve overall network performance.

An Integrated SON Experimental System for Self-Optimization and SON Coordination
In Self-Organizing Networks (SONs), a potentially large number of SON functions are available that autonomously perfom network management tasks. Different functions are e.g. available for the optimization of the network, and they can have conflicting goals. To ensure an effective optimization of the overall network, coordination of SON functions is necessary. For this purpose, we developed a po...

In the current telecommunication scenarios operators have to cope with fast technological changes while increasing operational efficiency, i.e. diminishing operational expenditures and, at the same time, maximising performance of the networks. In this paper we present an automated troubleshooting tool for cellular networks, based on Bayesian networks, which will contribute to improve operationa...

The recent developments in cellular networks, along with the increase in services, users and the demand of high quality have raised the Operational Expenditure (OPEX). Self-Organizing Networks (SON) are the solution to reduce these costs. Within SON, self-healing is the functionality that aims to automatically solve problems in the radio access network, at the same time reducing the downtime an...
