Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If advanced protocol stacks and resource management mechanisms are implemented in heterogeneous networks, then network performance and adaptability are improved, but system complexity increases

Engineering Contradiction:

Improvenetwork adaptabilityVSAvoidsystem complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments the network architecture into distinct protocol stacks for different technologies (LTE, NR, E-UTRAN, NG-RAN) with separate measurement and reporting mechanisms. Each protocol stack operates independently with its own configuration and measurement objects, allowing heterogeneous networks to function with reduced inter-dependency and manageable complexity.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent implements a universal measurement framework that operates across multiple radio access technologies. The same measurement procedures, reporting mechanisms, and quality of experience evaluation methods are applied universally to LTE, NR, and other technologies, enabling multi-functional measurement systems without requiring separate complex mechanisms for each technology.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If multiple protocol stacks for different technologies are integrated, then network versatility is improved, but measurement and management difficulty increases

Engineering Contradiction:

Improvetechnology compatibilityVSAvoidmeasurement difficulty

Core Design Contradiction:

Adaptability or versatilityVSDifficulty of detecting and measuring

Solution Approach 1:

The patent applies local quality by configuring measurement objects and reporting requirements specifically for each protocol stack and technology type. Each LTE, NR, or E-UTRAN connection has tailored measurement parameters, thresholds, and reporting configurations suited to its specific technology characteristics, while maintaining a unified overall measurement framework.

Inventive Principle:

Principle #3Local quality

AI summary

A first base station receives, from a core network element, a context message comprising an initial context setup request or a user equipment (UE) context modification. The context message comprises a quality of experience (QoE) measurement collection (QMC) configuration for a second base station associated with a wireless device. The first base station determines QMC activation for the second base station; and sends, to the second base station, a request including the QMC configuration. The first base station receives, from the second base station, a QoE measurement report associated with the second base station; and transmits the QoE measurement report to a multi-cell/multicast coordination entity (MCE).
