IPLOOK Technical Contributions & TDoc Archive

Official archive of 3GPP standardization proposals, Change Requests (CRs), and architectural specifications driving the evolution of 5G Core, Non-Terrestrial Networks (NTN / Satellite), Network Slicing, and Policy Control across Release 17 to Release 21.

WHY INDUSTRY PARTICIPATION MATTERS

More Connections.
More Opportunities.

By contributing directly to 3GPP Working Groups, we ensure our 5G Core and NTN architectures strictly align with global specifications—accelerating carrier-grade innovation and real-world deployment.

Open Standards & Interoperability

Direct adherence to 3GPP Rel-15 through Rel-21. We eliminate vendor lock-in by guaranteeing multi-vendor interoperability across gNodeBs, third-party UEs, and satellite payloads.

From Consensus to Production

Translating technical debates into production software. We track protocol evolution and bridge the gap between theoretical specifications and carrier-grade commercial stability.

Global Co-Author Ecosystem

Collaborative leadership. We actively co-author proposals with international operators, chipset leaders, and tier-1 vendors to build an open, future-proof mobile ecosystem.

FREQUENTLY ASKED QUESTIONS

3GPP Standards & Compliance FAQ

Key insights regarding our 3GPP working group engagement, multi-vendor interoperability, and commercial core network compliance.

Yes. All IPLOOK commercial core network elements (including AMF, SMF, UPF, PCF, UDM, and AUSF) strictly follow standard 3GPP Service-Based Architecture (SBA) specifications. By implementing standard open interfaces (N1, N2, N3, N4, and SBI), our systems eliminate proprietary lock-in and guarantee seamless integration into multi-vendor telecom ecosystems.
IPLOOK commercial 5G Core (5GC) solutions fully support 3GPP Release 15, Release 16, and Release 17 specifications in carrier deployments. Our R&D and standardization delegations are actively driving and integrating Release 18 (5G-Advanced) enhancements, with preliminary architectural studies extending toward Release 21 and 6G.
With over 40 technical contributions dedicated to Non-Terrestrial Networks (NTN), IPLOOK addresses critical satellite challenges including NGSO paging optimization, earth-moving cell mobility, satellite-gateway tracking areas, and on-board UPF service continuity. This allows satellite operators to deploy regenerative and transparent satellite payloads that seamlessly interoperate with terrestrial cellular networks.
Yes. Interoperability Testing (IOT) is a core validation pillar at IPLOOK. Because our software strictly adheres to 3GPP specifications, our core network functions have undergone comprehensive interoperability tests with leading radio access network (RAN) vendors, Open RAN platforms, mainstream 5G chipsets, and commercial terminal devices worldwide.
Our approved contributions—such as corrections to Network Slice AS Groups (TS 23.501), QoS policy parameters (TS 29.561), and network intent structures (TS 23.801)—resolve real-world operational bottlenecks identified during live carrier deployments. Participating in drafting these solutions ensures our commercial software is resilient against signaling storms, handover anomalies, and policy synchronization faults.
IPLOOK technical delegates actively participate across core 3GPP Working Groups, primarily SA2 (System Architecture and Services), CT3 and CT4 (Core Network Protocols and Data Management), RAN2 (Radio Layer 2/3 and Mobility), and TSG RAN/SA Plenary sessions. This end-to-end involvement allows us to align radio access signaling with cloud-native core architecture.
Through our standardized contributions to TS 23.501 and TS 23.700-62 regarding Network Slice AS Groups (NSAG) and multi-APN PDU sessions, IPLOOK eliminates signaling overhead during multi-slice handovers. In industrial and private enterprise deployments, this guarantees deterministic latency, automated slice isolation, and strict SLA fulfillment between IT and operational technology (OT) traffic.
Our advanced research team focuses on Release 18/19 5G-Advanced evolution and exploratory Release 21 6G frameworks. Key research initiatives include AI/ML-driven intent-based networking (TS 23.801), regenerative satellite core orchestration, Integrated Sensing and Communication (ISAC), and sub-millisecond edge compute federation.
