# Summary of pCR [FS_6G_MED] Considerations on Work Topic 1: Media Delivery requirements for intelligent immersive calling

## Document Information
- **Source:** Huawei
- **Specification:** 3GPP TR 26.870
- **Meeting:** TSG-SA4 Meeting #135 (February 2026, Goa, India)
- **Document Number:** S4-260080
- **Type:** Change Request for Approval

## Main Purpose

This pCR proposes updates to clause 4.2 of TR 26.870, introducing new requirements related to intelligent immersive calling services for 6G media delivery.

## Background and Rationale

The change is motivated by SA1's work on TR 22.870, which introduces use cases for immersive communication targeting aging populations. The use case envisions leveraging 6G technologies (particularly AI capabilities such as generative AI and multi-modal models) to enable operators to provide intelligent immersive calling services through various wearable and smart devices including:
- AR/VR glasses
- Smart glasses
- Smart TVs
- Smart watches

## Technical Contributions

### New Clause 4.2.1: The Intelligent Immersive Calling Service

The pCR introduces a new service definition describing intelligent immersive calling as:
- An AI-empowered immersive calling service utilizing generative AI and multi-modal models
- A service that aggregates inputs from multiple smart devices and sensors (cameras, smart watches, AR/VR glasses)
- A service that can be natively provided by operators

### Requirements for Intelligent Immersive Calling

The following technical requirements are introduced:

1. **High-Quality Video Support:** 4K + HDR uplink video capability for intelligent immersive calling

2. **Eye Tracking Support:** Ability to support eye tracking across different types of smart devices (e.g., AR/VR glasses)

3. **User Intention Understanding:** Capability to understand user intention through voice and gesture inputs

4. **Device-Aware QoE:** Tiered QoE support that takes the specific device capabilities into account

5. **IMS Extensions:** Extensibility of IMS to support these new capabilities

6. **Multi-Media Protocol Extensions:** Review of protocol extensions for multi-media transporting
