Engineering Contradiction Analysis
1Speed
If the terminal immediately initiates CHO evaluation after receiving CHO configuration, then the handover execution is prompt, but the flexibility of CHO implementation process is reduced and adaptability to different scenarios is limited
Solution Approach 1:
The patent introduces dynamic control of CHO evaluation timing through network-side triggered mechanisms. Instead of fixed immediate evaluation, the terminal can defer or activate CHO evaluation based on received triggering conditions (e.g., measurement thresholds, event occurrences). This dynamic approach allows the system to adapt evaluation timing to different scenarios while maintaining prompt execution when conditions are met.
Solution Approach 2:
The patent enables parameter-based control of CHO evaluation by introducing configurable thresholds and triggering conditions. The network can adjust measurement thresholds, evaluation activation conditions, and triggering parameters to optimize CHO implementation for different scenarios. This parameter flexibility resolves the contradiction by allowing both prompt execution (when parameters indicate readiness) and scenario adaptability (through parameter adjustment).

If the terminal initiates CHO-related measurement only when signal quality of source cell is lower than quality threshold, then the power consumption is reduced, but the flexibility of CHO implementation is reduced
Solution Approach 1:
The patent implements dynamic measurement activation controlled by network triggering conditions. Instead of fixed threshold-based activation, the terminal can activate measurements based on diverse triggering conditions including but not limited to signal quality thresholds. This dynamic control allows flexible adaptation to different scenarios while managing power consumption by activating measurements only when network-triggered conditions are met.
Solution Approach 2:
The patent introduces multiple configurable parameters for measurement activation beyond simple signal quality thresholds, including event-based triggers, network-controlled activation conditions, and scenario-specific parameters. This parameter expansion allows the system to balance power consumption and flexibility by selecting appropriate activation criteria for different operational scenarios.
