Feasibility of ITU‑T Y.3207 INCA in Dynamic NTN Environments

Determine the feasibility of the ITU‑T Y.3207 Integrated Network Control Architecture (INCA) centralized control framework in dynamic non‑terrestrial network environments, accounting for latency, signaling overhead, and onboard computational constraints that may impede practical deployment.

Background

The paper surveys existing integration frameworks across terrestrial and satellite systems and notes that ITU‑T Y.3207 (2024) defines the Integrated Network Control Architecture (INCA) for Fixed, Mobile, and Satellite Convergence (FMSC), proposing a centralized control model.

However, unlike relatively stable terrestrial deployments, non‑terrestrial networks experience high dynamics, intermittent connectivity, and strict timing/compute limitations. The authors explicitly state that feasibility of applying a centralized INCA approach to such environments is uncertain due to latency, overhead, and computational constraints, motivating investigation of practical viability and design adaptations.
