TM Forum Unveils High-Reliability AN Solutions Package

At the recent Innovate Asia Masterclass on Autonomous Networks (AN), hosted by TM Forum, industry expert Michael Wang from Huawei introduced a groundbreaking solution package aimed at core network fault management. This package is designed with a focus on high stability features and aligns with TM Forum's IG1500 standards, setting the stage for commercial rollout in core network solutions.

Key Developments in Core Network Stability

The newly launched solution pack emphasizes seven critical dimensions to ensure core network stability:
1. Architecture Distribution and High Stability
2. Disaster Recovery (DR) for Control Plane
3. DR for User Plane
4. Infrastructure DR
5. Peak Signal Suppression
6. Risk Forecasting
7. Service Degradation Recovery

Utilizing the Management Data Analysis Function (MDAF) as defined in the 3GPP TS 28.104 technical specification, this solution provides a systematic end-to-end resiliency framework for networks. It leverages digital twin technology to facilitate closed-loop management, enhancing the network's ability to withstand extreme scenarios such as signal storms.

A standout innovation is the storm risk assessment signaling. By modeling digital twins, the solution creates a virtual network environment to predict risks and employ proactive defenses. Before a signal storm occurs, it compiles traffic statistics, node connection data, and device timing configurations, followed by using a simulation engine to generate impact models. This process allows for accurate capacity assessment and optimization recommendations, enabling operators to mitigate potential failures ahead of time.

Accelerating Adoption Through Standardization

The AN solutions package strictly adheres to TM Forum's IG1500 standards and integrates seamlessly with existing systems through standardized APIs. In his presentation, Michael Wang emphasized that the package not only offers a standardized technical implementation model but also validates its effectiveness in core network stability assurance scenarios through the Catalyst project. He mentioned a best practice from an operator regarding infrastructure recovery post-disaster. Critical processes include the precise identification of VIP users, quickly determining recoverable paths, and rapidly generating recovery solutions. The primary objective is to reduce the network restoration time for VIP users from 30 minutes to just 1 minute, while maintaining a 30-minute recovery time for regular users.
This tailored approach to service assurance enhances the network experience for high-value users and effectively mitigates economic losses caused by VIP user churn.

With the official release of the AN solutions package, core network stability assurance is now integrated into TM Forum’s standard scenarios, showcasing Huawei's replicable and scalable paradigm for building high-stability networks. This initiative equips operators with powerful tools to enhance resiliency while also providing crucial support for network monetization evaluations.
