Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the network uses existing communication management processes, then basic communication control is maintained, but the network cannot perform communication management based on UE moving trajectory, satellite access signal coverage information, or battery level

Engineering Contradiction:
Improvecommunication management capabilityVSAvoidUE trajectory, satellite coverage, battery level information
Core Design Contradiction:
Adaptability or versatilityVSLoss of information

Solution Approach 1:

The patent segments the communication management system into multiple network elements (SCEF, MME, HSS) with distinct functions. The SCEF is responsible for receiving and managing external information from third-party servers, the MME processes communication control decisions, and the HSS stores subscription data. This segmentation allows each component to specialize in handling specific types of information (trajectory, satellite coverage, battery level) without overwhelming a single system, thereby improving adaptability while maintaining information integrity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The SCEF acts as an intermediary between third-party servers and the core network elements. It receives information updates containing UE trajectory, satellite coverage, and battery level data from external sources, processes this information, and forwards it to appropriate network elements (MME, HSS). This intermediary role enables the network to access external information sources without requiring direct integration between all components, thus enhancing communication management versatility while preventing information loss through standardized interfaces.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If the network obtains additional UE information (trajectory, satellite coverage, battery level), then communication control flexibility improves, but the system complexity increases

Engineering Contradiction:
Improvecommunication control flexibilityVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements a universal information update mechanism that can handle multiple types of UE information (trajectory, satellite coverage, battery level) through a single standardized interface at the SCEF. The same message structure and processing flow are used regardless of which specific information type is being transmitted. This multi-functionality approach allows the system to gain enhanced communication control flexibility across different scenarios without proportionally increasing system complexity, as the underlying infrastructure remains consistent.

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

Solution Approach 2:

The network performs preliminary actions by pre-configuring the SCEF, MME, and HSS to handle various types of UE information before actual communication events occur. Subscription information including trajectory, satellite coverage, and battery level parameters are prepared in advance and stored in the HSS. When information updates arrive, the pre-configured system can process them efficiently without requiring complex runtime decision-making, thus improving communication control flexibility while keeping system complexity manageable through advance preparation.

Inventive Principle:
Principle #10Preliminary action

3Use of energy by moving object

If the network implements communication management based on satellite coverage and battery level, then power-saving mechanisms can be activated, but the information processing overhead increases

Engineering Contradiction:
ImproveUE power consumptionVSAvoidinformation processing time
Core Design Contradiction:
Use of energy by moving objectVSLoss of time

Solution Approach 1:

The patent implements a self-service mechanism where the network automatically processes satellite coverage and battery level information to activate power-saving mechanisms without requiring manual intervention or complex external coordination. The SCEF receives battery level and satellite coverage updates, the MME automatically evaluates these against predefined thresholds, and power-saving modes are triggered autonomously. This self-service approach minimizes information processing time by eliminating human decision-making loops and external coordination delays, allowing rapid activation of power-saving features that directly benefit UE energy consumption.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system establishes a feedback loop where battery level and satellite coverage information continuously flow from the UE and third-party servers through the SCEF to the MME, which then adjusts communication management parameters and power-saving settings accordingly. This real-time feedback mechanism enables the network to respond dynamically to changing UE conditions, optimizing power consumption based on actual battery status and coverage availability. The automated feedback process reduces information processing time compared to periodic manual assessments, as the system continuously monitors and adjusts without interruption.

Inventive Principle:
Principle #23Feedback
