GlobalData and Huawei release high-stability core network white paper

During the 2023 5G Core Network Summit, GlobalData, a world-renowned consulting firm, released the High-Stability Core Network White Paper together with AIS, Entel, Sunrise, Türk Telekom, and Huawei. The white paper is industry’s first to systematically analyze the reliability challenges faced by cloud-native core networks and propose a core network reliability standard to classify different health states. It provides a frame and methodology for a high-stability network.

As 5G and cloud technologies evolve, services become more diversified. At the same time as the emergence of these technologies are software and hardware decoupling, multi-generation coexistence, complex inter-generation APIs, signaling surge, transport network faults, as well as data center faults which are exerting greater pressure on operators to maintain carrier-grade reliability of the core network. According to GlobalData, 42% of operators have experienced core network service interruptions in the past three years, and the interruption frequency increases annually.

Based on four common network metrics: traffic, latency, errors, and saturation, the white paper classifies core network health states as Normal, Pre-warning, Subhealth, Overload, Single NF Fault, and Multiple NF Fault. It proposes the core network reliability standard “STABLE”, where different measures are taken at different network phases to ensure that incidents do not accumulate or escalate, showing a systematic methodology to enhance the reliability of the core network.
