Solution Overview

Problem

Extended reality (XR) services, such as augmented, virtual, and mixed reality, require low latency communication to provide seamless experiences for applications like gaming, but conventional communication technologies like VoIP and VoLTE cannot meet the latency demands, necessitating real-time connection management and quality of service (QoS) adjustments.

Innovation Solution

An electronic device method that dynamically manages communication connections by establishing and switching between different radio access technologies (RAT) and bearers based on changing QoS requirements, ensuring low latency by maintaining optimal connections for XR services, including Wi-Fi, LTE, and 5G, and measuring QoS for multiple XR servers to determine the best access points.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of time

If conventional communication technologies like VoIP or VoLTE are used, then device complexity is reduced, but latency time exceeds the required threshold for XR services

Engineering Contradiction:
Improvelatency timeVSAvoidcommunication connection management
Core Design Contradiction:
Loss of timeVSDevice complexity

Solution Approach 1:

The system dynamically adjusts communication connections by establishing and switching between multiple RATs (Wi-Fi, LTE, 5G) and bearers based on real-time QoS requirements. The electronic device monitors QoS parameters and adaptively manages communication paths to maintain latency below 10ms for XR services, transforming the static communication approach into a dynamic one that responds to changing service demands.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes communication parameters by selecting different RATs and bearers based on QoS values. When QoS requirements change (e.g., from first value to second value), the system establishes new communication connections with appropriate parameters while maintaining existing connections, thereby optimizing latency performance without completely reconfiguring the communication system.

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If multiple communication connections are established and maintained, then QoS adaptability is improved, but device complexity increases

Engineering Contradiction:
ImproveQoS adaptabilityVSAvoidconnection management
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The communication system is segmented into multiple independent connections (first communication connection, second communication connection, third communication connection), each corresponding to different QoS values and RATs. This segmentation allows the system to manage complexity by treating each connection as a separate entity with specific QoS characteristics, while the overall system gains adaptability through the diversity of available connections.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The electronic device implements multi-functionality by capable of establishing and maintaining multiple types of communication connections (different RATs and bearers) within a single device. This universal capability allows the device to adapt to various QoS requirements using the same underlying communication framework, reducing the need for separate specialized systems.

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

3Reliability

If communication connections are frequently switched based on QoS changes, then service quality is improved, but loss of time due to connection establishment increases

Engineering Contradiction:
Improveservice qualityVSAvoidconnection establishment time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system performs preliminary actions by establishing multiple communication connections in advance (first communication connection, second communication connection) before QoS changes occur. When QoS requirements change, the system can switch to pre-established connections rather than creating new ones, significantly reducing connection establishment time while maintaining service quality.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system maintains continuous useful action by keeping multiple communication connections active simultaneously (maintaining first communication connection while establishing second communication connection). This continuity ensures that when QoS changes occur, the system can immediately utilize existing connections without interruption, avoiding the time loss associated with establishing new connections from scratch.

Inventive Principle:
Principle #20Continuity of useful action
