Solution Overview

Problem

There is a lack of research and effective solutions for selecting Quality of Service (QoS) for Extended Reality (XR) services, which is an urgent issue in the communication technology field.

Innovation Solution

A communication method and apparatus that involve receiving indication information about QoS from a second communication apparatus, determining the QoS based on the received information, and using it to perform XR services, while also considering image processing capabilities and parameters such as image rendering and transmission manners.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If QoS selection for XR services is not addressed, then XR service quality cannot be guaranteed, but implementing comprehensive QoS selection mechanisms increases system complexity

Engineering Contradiction:
ImproveXR service qualityVSAvoidQoS selection mechanism
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies preliminary action by pre-configuring multiple QoS parameters and their corresponding thresholds in the network device before XR service establishment. The system prepares QoS profiles with different priority levels, bandwidth allocations, and latency requirements in advance, enabling rapid selection during service deployment without complex real-time calculations.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent utilizes parameter changes by dynamically adjusting QoS parameters based on detected terminal capabilities and network conditions. The system modifies key parameters such as priority level, bandwidth, and packet loss thresholds according to the terminal's processing power, display capabilities, and current network state, achieving adaptive QoS optimization without requiring overly complex selection algorithms.

Inventive Principle:
Principle #35Parameter changes

2Productivity

If image processing capabilities are considered in QoS determination, then terminal device performance is optimized, but information exchange between devices increases

Engineering Contradiction:
Improveterminal device performanceVSAvoidinformation exchange
Core Design Contradiction:
ProductivityVSLoss of information

Solution Approach 1:

The patent applies the extraction principle by selectively obtaining only the essential image processing capability parameters from the terminal device, such as rendering capability levels, processing speed thresholds, and supported resolutions. The system extracts only the necessary information needed for QoS determination, filtering out redundant device details and focusing on parameters that directly impact XR service quality.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent implements universality by designing a standardized capability indication mechanism that can be applied across different terminal types and XR applications. The same QoS determination framework works for various image processing scenarios (rendering, transmission, processing) and device categories, reducing the need for device-specific information exchange protocols.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

A communication method includes receiving, by a first communication apparatus, indication information from a second communication apparatus, and determining, by the first communication apparatus, a first quality of service (QoS) of the extended reality (XR) service based on the at least one piece of QoS of an XR service. The first communication apparatus is a core network device or an access network device. The indication information is useable to indicate at least one piece of QoS of the XR service. The XR device receives data of the XR service or sends data of the XR service by a terminal device. The second communication apparatus is an XR server or a chip in the XR server.
