Comprehensive Visibility: An In-Depth Analysis of How TNIS Achieves Full-Standard Telecom network metadata Reconstruction from 2G to 5G

I. Forensic Challenges Brought by Mobile Network Evolution

From traditional 2G/3G networks to today’s 5G SA architecture, the complexity of telecommunications networks has grown exponentially. The widespread adoption of encrypted protocols, the popularity of IMS high-definition voice services, and the decoupling of 5G core network elements such as AMF and UPF have created significant challenges for intelligence agencies seeking effective investigative clues.

Sinovatio TNIS is designed to address the challenges of network metadata reconstruction across all generations of telecom networks through an integrated solution, enabling comprehensive visibility and analysis across full-standard network environments.

II. Modular Architecture: From Raw Packets to Actionable Intelligence

TNIS adopts an advanced “Access – Reconstruction – Analysis” architecture to ensure efficient and complete data processing:

● Traffic Access Layer (FlowWare): Supports high switching capacities and enables non-intrusive access to raw traffic from high-speed physical links such as 100GE through methods including optical splitting, TAP, and high-impedance bridging.

● Protocol Processing Layer (Probe Sub-system): Composed of four core modules—APF (Protocol Preprocessing), PPF (Protocol Parsing), DPF (Data Processing), and TPF (Three-Identifier Correlation). It accurately extracts protocols such as BSSAP, RANAP, S1AP, and the latest NGAP (5G) from complex signaling streams, while completing critical MSISDN-IMSI-IMEI association.

III. Smooth Evolution and Decryption Capability in the 5G Era

For 5G core networks, TNIS demonstrates strong adaptability:

● Comprehensive Interface Coverage: Supports key signaling interfaces such as N1, N2, and N11, as well as voice interfaces including SGi and Gm.

● Encrypted network metadata Reconstruction: By obtaining authentication information through interfaces such as Cx, the system enables transparent reconstruction of VoNR voice and SMS network metadata, ensuring continuity of intelligence acquisition in secure 5G environments.

IV. Conclusion: Building a Robust Foundation for Telecom Regulation

TNIS not only provides processing capabilities for millions of subscribers but also ensures 24/7 stable operation through hardware redundancy and carrier-grade architecture design. It has become an indispensable technological foundation for telecommunications regulation and security operations in the digital era.
