Solution Overview

Problem

The introduction of lightweight terminals in wireless communication systems negatively impacts the performance of common terminals due to similar access control methods, leading to inefficiencies and performance degradation.

Innovation Solution

Implementing an access control method that differentiates between lightweight and common terminals by utilizing specific synchronization signals, system information blocks, and target indication information to determine cell support and access/camping permissions, thereby isolating the impact of lightweight terminals on common terminals.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If the same access control method is applied to both lightweight terminals and common terminals, then the access control process is simple and unified, but the performance of common terminals deteriorates due to the large number of lightweight terminals accessing the system

Engineering Contradiction:
Improveaccess control process complexityVSAvoidsystem performance
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The patent segments the access control process by introducing different access control parameters for lightweight terminals and common terminals. Specifically, it uses terminal type identification to divide terminals into different categories and applies different access control methods (first access control parameter for lightweight terminals, second access control parameter for common terminals), thereby resolving the contradiction between unified simplicity and performance protection.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent applies local quality by customizing access control parameters according to terminal types. Different access control parameters are applied to different terminal categories based on their specific characteristics and requirements, allowing the system to optimize for each terminal type locally rather than using a one-size-fits-all approach.

Inventive Principle:
Principle #3Local quality

2Adaptability or versatility

If lightweight terminals are allowed to access the system without restriction, then the adaptability and coverage of the system is improved, but the system performance and resource allocation efficiency deteriorates

Engineering Contradiction:
Improvesystem coverageVSAvoidresource allocation efficiency
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The patent implements dynamic access control by adjusting access control parameters based on terminal types and system conditions. The access control parameters are not fixed but are dynamically selected based on the terminal category (lightweight or common) and can be further adjusted based on system load and resource availability, thereby maintaining both adaptability and efficiency.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes access control parameters according to terminal types and system states. Different access control parameters (first parameter for lightweight terminals, second parameter for common terminals) are applied based on terminal classification, and these parameters can be dynamically adjusted based on system conditions such as resource availability and load, resolving the contradiction between coverage and efficiency.

Inventive Principle:
Principle #35Parameter changes

3Reliability

If access control parameters are differentiated by terminal type, then the system performance and resource allocation is optimized, but the access control mechanism becomes more complex

Engineering Contradiction:
Improvesystem performanceVSAvoidaccess control mechanism complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent segments the access control mechanism into distinct branches based on terminal type identification. By dividing terminals into lightweight and common categories and applying different access control parameters to each segment, the system achieves performance optimization while keeping each segment's control logic relatively simple and manageable.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent performs preliminary classification of terminals by type before applying access control. By identifying terminal types in advance and pre-defining different access control parameters for different terminal categories, the system prepares the control mechanism beforehand, reducing the complexity of real-time decision-making while maintaining performance optimization.

Inventive Principle:
Principle #10Preliminary action

4Ease of operation

If all terminals use the same access control parameters, then the ease of operation and implementation is maintained, but the performance degradation of common terminals due to lightweight terminal access cannot be prevented

Engineering Contradiction:
Improveaccess control implementation easeVSAvoidcommon terminal performance
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent segments the access control implementation into type-specific branches. By dividing terminals into categories and applying different access control parameters to each category, the system maintains ease of operation within each segment while preventing performance degradation through differentiated control, thus resolving the contradiction between operational simplicity and performance protection.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent applies local quality by customizing access control parameters for specific terminal types rather than using a uniform approach. This allows the system to maintain simple and straightforward access control for each terminal type locally, while the overall system benefits from differentiated parameters that protect common terminal performance.

Inventive Principle:
Principle #3Local quality
