The 3GPP SA2 working group is currently debating three competing 6G core network architectures, reflecting a divide between evolutionary approaches favored by Western operators and a revolutionary agent-based model supported by Chinese vendors. These architectural decisions will significantly impact how AI is integrated into network signaling and influence future device-side service execution.
The selection of a core architecture determines whether network intelligence remains under operator control or shifts toward device-side AI agents and hyperscalers. If 3GPP adopts an operator-centric framework, it could potentially lock out third-party OTT ecosystems from dynamically adapting network parameters for high-bandwidth services like cloud gaming. This technical friction risks a bifurcated global market, where Chinese domestic networks operate on a revolutionary single-vendor stack while the rest of the world utilizes an evolutionary multi-vendor model. Industry observers should monitor the November plenary session for a potential compromise that merges modular AI routing with existing 5G signaling protocols.
The debate over wireless deployments highlights the broader regulatory challenges in balancing infrastructure innovation with legacy network standards. As the industry moves toward broadband convergence, these architectural decisions will become increasingly critical for long-term network security, especially as public broadcasters adopt software-defined production to maintain their competitive edge. These shifts occur alongside global AI regulatory frameworks that are currently shaping how international standards bodies approach emerging technologies, including the ATSC B2X candidate standard designed to bridge broadcast and mobile ecosystems.
The 3GPP SA2 working group is currently debating three competing 6G core network architectures. This debate highlights a divide between evolutionary designs favored by Western operators and revolutionary agent-based models pushed by Chinese vendors. The final decision will determine whether network intelligence remains under operator control or shifts toward device-side AI.
The proposals range from evolutionary designs that preserve 5G service-based architecture with a separate AI domain to revolutionary models that replace traditional mobile signaling with dynamic intent coordination.
Seventeen major operators, including T-Mobile USA and Verizon, are demanding upgradable paths to protect their existing capital expenditures in 5G standalone networks.
A split could result in Chinese domestic networks operating on a revolutionary single-vendor stack, while the rest of the world utilizes an evolutionary multi-vendor model, creating significant technical friction.
Nokia, Ericsson, and NVIDIA are among the companies backing the direction that proposes a separate AI domain to preserve the existing 5G service-based architecture.
