Solution Overview

Problem

Existing mobile communication technologies fail to effectively recognize and process the unique traffic characteristics of extended reality (XR) and cloud gaming (CG) applications, which are characterized by quasi-periodic traffic with high data rates and variable jitter, leading to unsuitable UE discontinuous reception configurations and battery power limitations.

Innovation Solution

A method and device for processing packet data by considering application traffic characteristics using information from the higher/application layer, involving radio resource configuration and distinct processing of user plane data based on received information.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If current UE discontinuous reception configuration is used, then battery power consumption is reduced, but it is unsuitable for XR traffic with non-integer period and variable data rate

Engineering Contradiction:
Improvebattery power consumptionVSAvoidadaptability to XR traffic characteristics
Core Design Contradiction:
Use of energy by moving objectVSAdaptability or versatility

Solution Approach 1:

The patent applies dynamics by making the DRX configuration adaptable to varying XR traffic characteristics. The network dynamically adjusts DRX parameters based on real-time traffic patterns, allowing the system to transition from static to dynamic operation. This enables the DRX mechanism to accommodate non-integer periods and variable data rates while maintaining energy efficiency.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent implements parameter changes by modifying DRX configuration parameters to match XR traffic characteristics. The system changes parameters such as DRX cycle length, on-duration, and inactivity timer based on observed traffic patterns. This allows the DRX mechanism to adapt to non-integer periods and variable data rates, resolving the contradiction between energy saving and adaptability.

Inventive Principle:
Principle #35Parameter changes

2Speed

If XR applications require high throughput and low latency, then service quality is improved, but packets within one frame become dependent on each other

Engineering Contradiction:
Improvedata rateVSAvoidpacket independence
Core Design Contradiction:
SpeedVSStability of the object's composition

Solution Approach 1:

The patent applies segmentation by dividing the packet stream into frames with explicit delimiters. This segmentation allows the system to maintain packet dependency information within frames while enabling independent processing of multiple frames. The frame-based structure with delimiters provides a boundary that separates dependent packets, allowing high throughput while managing packet relationships through structured organization.

Inventive Principle:
Principle #1Segmentation

3Productivity

If XR traffic with high data rate and variable jitter is transmitted, then service requirements are met, but current mobile communication technology does not provide specific recognition and processing methods

Engineering Contradiction:
Improvedata transmission efficiencyVSAvoidtraffic recognition and processing complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent implements feedback by establishing a closed-loop system where traffic characteristics are continuously monitored and fed back to the network. The network uses this feedback to dynamically adjust DRX configuration and resource allocation. This feedback mechanism enables efficient handling of high data rate traffic with variable jitter while keeping the system manageable through automated adaptive control.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent applies self-service by enabling the system to automatically adapt to XR traffic characteristics without manual intervention. The DRX mechanism self-adjusts based on observed traffic patterns, and the network automatically recognizes and processes XR traffic types. This self-service capability improves data transmission efficiency while reducing the operational complexity of traffic management.

Inventive Principle:
Principle #25Self-service
