LS on AIML data collection
From InterDigital
Summary
This liaison statement from RAN to SA groups presents 4 options for AI/ML data collection for UE-side model training, seeking SA input by RAN#106 to resolve consensus issues on MNO controllability and UP tunnel feasibility. The document contains no formal proposals but establishes requirements and analysis framework for standardized data collection solutions.
Position
InterDigital is advocating for a comprehensive framework that balances MNO control with standardized AI/ML data collection, pushing for solutions that ensure full MNO controllability and visibility while maintaining privacy compliance. They are seeking SA group input to resolve technical feasibility questions rather than taking a strong stance on any particular option.
Key proposals
- Option 1a: UE collects and directly transfers training data to OTT server outside MNO via 3GPP or non-3GPP network with no standardization impact
- Option 1b: UE transfers data to server inside MNO for collection, then optionally to external OTT server, with FFS level of MNO controllability
- Option 2: UE transfers data to Core Network which forwards to data collection server/OTT server via NAS procedures
- Option 3: UE transfers data to gNB then OAM which forwards to data collection server/OTT server via RRC procedures
- Requirement: Data collected must be secured with integrity and confidentiality ensured for standardized solutions
- Requirement: User data privacy, anonymity and user consent must be respected in all solutions
- Requirement: MNO must have full control of standardized data collection transfer process without needing SLA
- Requirement: MNO must have full visibility for standardized data content
- Requirement: Standardized solutions should minimize air interface overhead and impact to network operation
- Three visibility options: Full visibility for standardized data, partial visibility for partially standardized data, no standardized visibility
- CP tunnel option requires data volume to remain within NAS/RRC signalling capacity limits
- UP tunnel feasibility for Options 2 and 3 remains unresolved (Note 7)
- ACTION: TSG SA requested to initiate work and SA2 to provide inputs on solutions 1b, 2, and 3 by RAN#106
- Privacy compliance: All data collection mechanisms must comply with privacy protection regulations and policies
- Protocol layers: Application layer for Options 1a/1b, NAS layer for Option 2, RRC layer for Option 3
