Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If mobile devices select infrastructure equipment based solely on signal strength, then connection establishment is simplified, but network performance deteriorates due to suboptimal cell selection and excessive handovers
Solution Approach 1:
The patent introduces multiple parameters beyond signal strength (BTS class identifiers, coverage area size, user movement speed) to evaluate and select infrastructure equipment. This multi-parameter approach changes the selection criteria from a single metric to a comprehensive evaluation system, resolving the contradiction by maintaining selection simplicity while improving network performance through more informed decisions
2Reliability
If mobile devices frequently handover between infrastructure equipment to maintain signal quality, then connection reliability is improved, but network efficiency deteriorates due to excessive handover operations
Solution Approach 1:
The patent performs preliminary evaluation of infrastructure equipment using BTS class identifiers and coverage area information before handover is triggered. By pre-assessing the suitability of target cells based on their characteristics rather than waiting for signal degradation, the system reduces unnecessary handovers while maintaining connection quality, thus improving network efficiency
Solution Approach 2:
The system incorporates user movement speed as a feedback parameter to dynamically adjust handover behavior. When users are detected to be moving rapidly, the system modifies its handover criteria to prevent excessive switching, thereby maintaining connection reliability while reducing network overhead from frequent handovers
3Area of stationary object
If infrastructure equipment coverage areas overlap extensively, then network coverage is improved, but device complexity increases due to difficulty in selecting optimal infrastructure equipment
Solution Approach 1:
The patent segments the network infrastructure into classified categories using BTS class identifiers that represent different coverage area sizes and characteristics. This segmentation allows mobile devices to systematically evaluate and select appropriate infrastructure equipment based on their current needs and movement patterns, reducing selection complexity while maintaining extensive coverage
