Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual testing and analysis methods are used to identify miss-configured 2G neighbors, then problem detection can be performed, but the process requires extensive manpower, resources, and time, and users experience poor network quality before the problem is solved
Solution Approach 1:
The system enables user equipment to automatically measure and report 2G neighbor cell signals, with the network side automatically analyzing reports and identifying miss-configured neighbors. This self-service mechanism eliminates the need for manual testing and continuous optimization, allowing the network to autonomously detect and correct configuration issues.
Solution Approach 2:
The system establishes a feedback loop where user equipment continuously measures 2G neighbor signals and reports back to the network side. The network side analyzes these reports and uses the feedback information to identify and correct miss-configured neighbors, enabling continuous automatic optimization without manual intervention.
2Reliability
If comprehensive 2G neighbor lists are configured to ensure complete coverage, then handover and reselection quality improves, but the device complexity and configuration difficulty increase
Solution Approach 1:
Instead of requiring manual configuration of comprehensive neighbor lists, the system enables automatic measurement and reporting by user equipment. The network side processes these reports and automatically identifies appropriate neighbors, eliminating the complexity of manual list configuration while ensuring reliable handovers and reselections.
Solution Approach 2:
The system pre-configures measurement parameters and thresholds in the operation and maintenance center. User equipment automatically performs measurements based on these pre-set parameters, and the network side has pre-established criteria for identifying miss-configured neighbors, eliminating the need for complex real-time configuration decisions.
3Reliability
If frequent manual optimization of 2G neighbor lists is performed to maintain network quality, then service continuity improves, but operational costs and resource consumption increase
Solution Approach 1:
The system transforms the optimization process from a manual, resource-intensive operation to an automatic self-service mechanism. User equipment continuously measures and reports 2G neighbor signals, and the network side automatically analyzes reports and updates configurations, eliminating the need for frequent manual optimization interventions and reducing operational costs.
Solution Approach 2:
The system establishes continuous measurement and reporting operations where user equipment constantly monitors 2G neighbor signals. This continuous flow of measurement data enables the network side to maintain up-to-date neighbor information without interruption, ensuring service continuity while eliminating periodic manual optimization cycles.
