Does Lawful Interception
also apply for Satellite Networks?

Background

With the integration of Satellite Networks, also known as Non‑Terrestrial Networks (NTN), into 5G and future 6G architectures they are becoming an essential extension of traditional telecommunications infrastructure. While enabling truly global connectivity – especially in underserved areas – this evolution introduces new requirements for regulatory capabilities such as Lawful Interception (LI).

Existing LI frameworks, as defined by ETSI and 3GPP, were primarily designed for terrestrial and relatively centralized network environments. NTN, however, introduces a highly distributed, cross-border, and dynamic architecture.

Challenges for Lawful Interception in NTN

The adoption of NTN brings several key technical and regulatory challenges:

• Distributed Architecture: Communication paths traverse satellites, gateways, and multiple network domains
• Jurisdictional Complexity: Users, satellites, and gateways are often located in different countries
• Dynamic Network Conditions: Mobility, beam switching, and constantly changing satellite connectivity
• Enhanced Encryption: Combination of 5G security and satellite-specific protection mechanisms
• Interoperability Requirements: Seamless integration of terrestrial and non-terrestrial network segments

These factors complicate the consistent delivery of Intercept Related Information (IRI) and Content of Communication (CC) in line with regulatory obligations.

Standardization and ETSI Activities

ETSI is actively driving the evolution of LI standards to address NTN requirements. Key focus areas include:

• Definition of NTN-specific interception scenarios
• Support for multi-jurisdiction and multi-operator environments

Our Approach: Extending LI Solutions for NTN

The LI solution of Nexburg is being systematically enhanced to fully support NTN environments.

Key capabilities include:

• Support for NTN architectures, including satellite gateways and hybrid deployments
• Integration with 5G Service-Based Architecture (SBA) extended to NTN
• Advanced mediation and delivery functions for distributed interception sources
• Scalable, cloud-native design to handle highly dynamic network conditions
• Alignment with evolving ETSI and 3GPP standards

Collaboration with ETSI

Nexburg is closely collaborating with ETSI and actively contributing to relevant standardization initiatives.

This collaboration enables:

• Early adoption of emerging requirements in product development
• Active contribution to NTN-related LI specifications
• Ensuring regulatory compliance across global markets

Conclusion

Non‑Terrestrial Networks are a key pillar of future communication infrastructures. At the same time, they require a fundamental evolution of established Lawful Interception concepts.

Through the continuous adaptation of standards and technologies, telecommunications providers can meet regulatory requirements in satellite-based networks while simultaneously leveraging the benefits of global connectivity.
