IG1251C AN Level 4 Target Architecture v1.0.0

In the push toward Level 4 Autonomous Networks, CSPs must not only adopt new processes and organizational changes but also implement function-centric building blocks that enable advanced autonomy. This guide defines how functions across Business, Service, and Resource operational layers (augmented by AI) can deliver: End-to-End Automation  Functional blocks that handle everything from customer onboarding to real-time fault management, requiring minimal human intervention. Scenario-Based Intelligence  AI/GenAI embedded within functional blocks—sometimes referred to as “intelligence” or “endogenous intelligence”—provides continuous learning, predictive analysis, and dynamic decision-making. High-Value Scenarios  Adapting the AN Framework approach (IG1218F, IG1339), CSPs select operational scenarios (e.g., fault management, complaint handling, network change) that yield tangible ROI and business value (i.e., “High-Value Scenarios).
