IG1501B AN L4 Core Network Fault Management Solution Package v1.0.0

The TM Forum Autonomous Networks (AN) Project has established a series of standards, including glossaries (such as IG1258), reference architectures (like IG1251), metric systems (IG1256), high-value scenario grading standards (IG1339), and assessment tools (IG1252 & GB1059). To assist users in quickly starting their AN Level 4 journey without needing extensive knowledge of the TM Forum AN standards and their background, the IG1500 series of documents provides instantiated descriptions that connect TM Forum Autonomous Networks standards, allowing users to intuitively understand the application and deployment of AN standards in real business scenarios. This document presents the solution package for Core Network Fault Management within the AN L4 framework. Using real Core Network faults as examples, it outlines how to define effectiveness indicators, evolution goals, reference architecture, and workflows for Core Network fault management under the AN L4 structure. Additionally, the document lists common Core Network faults to provide readers with standardized solutions, facilitating a swift initiation of their AN L4 immigration journey.
