A domain-oriented method for evaluating 5G core network software quality

Abstract. This paper examines approaches to assessing the quality of fifth-generation (5G) core network software. A method is proposed that combines standard quality metrics in accordance with ISO/IEC 25010 with additional criteria relevant to 5G telecommunication systems, such as latency, scalability, energy efficiency, adaptability, and fault tolerance. A three-tier model is developed, enabling multidimensional assessment of core software considering service, functional, and infrastructure levels. Simulations were conducted to evaluate the method’s effectiveness under different scenarios, including load variation, component version updates, and node failures. The proposed approach demonstrates higher precision and practical applicability compared to existing methods. Graphs, block diagrams, and experimental results are presented. Prospects for implementation and future research directions are outlined. Keywords: software, 5G, ISO/IEC 25010, QoS, software quality.
