3GPP TR 26.836 V0.0.1 - Study on QUIC-based Media Delivery Solutions for Real-Time Communication (Release 20)

Document Overview

This is an initial skeleton document for a Technical Report studying the application of QUIC-based media delivery protocols to 3GPP Real-Time Communication (RTC) systems. The document is in its early draft stage (V0.0.1) and contains primarily editor's notes outlining the intended structure and scope of the study.

Main Technical Scope

The study aims to evaluate QUIC-based media delivery protocols for integration into the 3GPP RTC system, examining their applicability, benefits, limitations, and potential architectural impacts.

Technical Content Structure

1. QUIC-based Media Delivery Protocols (Clause 4)

Objective: Survey and document existing and emerging QUIC-based media delivery protocols.

Planned Content:
- Individual protocol descriptions including:
- Introduction and features
- Benefits and limitations from RTC perspective
- Current applications
- Summary and comparison of surveyed protocols

Note: Comparison with existing RTC system will be addressed in the evaluation clause rather than here.

2. Evaluation of QUIC-based Protocols for RTC (Clause 5)

This clause forms the core technical contribution, structured into three main evaluation dimensions:

2.1 Application Scenarios (Clause 5.2)

• Definition of potential RTC service scenarios where QUIC-based media delivery could be applied
• Individual scenario descriptions to be provided in subsequent subclauses

2.2 Architectural and Functional Evaluation (Clause 5.3)

Scope of Analysis:
- Impacts on RTC media delivery architecture (TS 26.506)
- Impacts on 5G Core Network architecture (TS 23.501)
- Impacts on UE implementations

Per-Protocol Analysis:
- Applicability to defined application scenarios
- Potential architectural enhancements required for integration
- Advantages and disadvantages for each scenario
- Summary of findings

2.3 Performance Evaluation (Clause 5.4)

Methodology:
- Utilizes test framework from TR 26.934 ("Test platform for media delivery technologies")

Content:
- Definition of appropriate performance metrics for QUIC-based protocols
- Per-protocol evaluation including:
- Evaluation conditions
- Results obtained using TR 26.934 framework

2.4 Evaluation Summary (Clause 5.5)

• Overall assessment including:
• Advantages and disadvantages for RTC system
• Benefits for application scenarios
• Performance evaluation results

3. Integration into RTC System (Clause 6)

Conditional Scope: This clause will only be populated if QUIC-based protocols are found beneficial based on Clause 5 evaluation.

Planned Content:
- Potential integration scenarios
- Candidate solutions for integration
- Summary of solutions including:
- Evaluation/comparison of solutions
- Potential normative work requirements

4. Conclusions and Recommendations (Clause 7)

Final conclusions and recommendations based on the study findings.

Key Dependencies and References

• TR 26.934: Test platform for media delivery technologies (used for performance evaluation framework)
• TS 26.506: RTC media delivery architecture (baseline for architectural evaluation)
• TS 23.501: 5G Core Network architecture (for network-level impact analysis)

Study Approach

The document follows a systematic evaluation methodology:

1. Survey Phase: Identify and characterize QUIC-based protocols
2. Scenario Definition: Define relevant RTC application scenarios
3. Multi-dimensional Evaluation: Assess protocols from architectural, functional, and performance perspectives
4. Integration Analysis: Develop potential integration solutions (if justified)
5. Recommendations: Provide conclusions and guidance for potential normative work

Current Status

This is a skeleton document (V0.0.1) from SA4#135 (February 2026) containing only structural placeholders and editor's notes. No technical content, evaluation results, or specific protocols have been documented yet. The structure indicates a comprehensive study approach covering protocol analysis, scenario-based evaluation, and potential standardization pathways.
