Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the mobile radio device attempts to connect to base stations in random or unranked order, then the device can eventually find a base station with satisfactory connectivity, but the time required to establish a connection increases due to multiple unsuccessful attempts
Solution Approach 1:
The system performs preliminary actions by gathering status information from multiple base stations before actual connection attempts. The mobile radio device receives status information indicating connectivity characteristics of second plurality of base stations, then uses this information to pre-rank candidates before attempting connections, thereby avoiding wasted connection attempts on poor candidates
Solution Approach 2:
The system implements feedback by using status information received from base stations to continuously update and refine the ranked list of candidates. The mobile radio device uses the received status information defining connectivity characteristics to adjust the ranking, creating a feedback loop that improves connection selection over time
2Reliability
If the mobile radio device uses beam steering to scan through multiple base stations to assess connectivity, then the device can identify suitable base stations, but the complexity of the connection process increases
Solution Approach 1:
The system introduces an intermediary mechanism by using status information as a mediator between the mobile radio device and base stations. Instead of directly attempting connections to assess connectivity, the device receives status information that mediates the assessment process, simplifying the overall connection process while maintaining reliability
Solution Approach 2:
The base stations perform self-service by providing status information about their own connectivity characteristics. Each base station communicates its own connectivity status to the mobile radio device, eliminating the need for the mobile device to perform complex active scanning and assessment procedures
