Innovation Solution

An electronic device dynamically controls EN-DC operations based on network state without requiring software updates, enabling seamless communication across different network environments.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the user terminal transmits information according to the NR specification, then the user terminal can communicate with the NR network, but a network which does not support the NR network receives unnecessary information causing network overload

Engineering Contradiction:
Improvenetwork compatibilityVSAvoidnetwork overload
Core Design Contradiction:
Adaptability or versatilityVSObject-generated harmful factors

Solution Approach 1:

The user terminal dynamically adjusts its communication behavior based on real-time network capability detection. The terminal determines whether to transmit NR information based on whether the network supports NR, changing its operation mode from static to adaptive, thereby avoiding unnecessary information transmission to non-NR networks while maintaining compatibility with NR networks

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The user terminal receives network information (such as system information blocks) that indicates whether the network supports NR. Based on this feedback, the terminal adjusts its information transmission behavior accordingly, enabling the network to control the terminal's communication mode and prevent overload on networks that do not support NR

Inventive Principle:
Principle #23Feedback

2Object-generated harmful factors

If the user terminal updates software to prevent network overload, then the network overload problem is reduced, but the user terminal requires frequent software updates

Engineering Contradiction:
Improvenetwork overloadVSAvoidsoftware update frequency
Core Design Contradiction:
Object-generated harmful factorsVSDevice complexity

Solution Approach 1:

The user terminal autonomously detects network NR support capability and automatically adjusts its own communication behavior without requiring external software updates. The terminal uses its own resources to determine network compatibility and makes decisions about information transmission independently, eliminating the need for frequent software updates from the terminal side

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The network provides feedback information (network capability indicators) to the user terminal, enabling the terminal to adapt its behavior based on the network's capabilities. This feedback mechanism shifts the complexity from the terminal software to the network side, where the network can control information transmission based on its own capabilities

Inventive Principle:
Principle #23Feedback
