1Speed
If event-triggered L1/L2 measurement reporting is implemented, then network performance and response time are improved, but signaling overhead and processing complexity increase
Solution Approach 1:
The patent changes the reporting trigger parameters from periodic time-based triggers to event-based triggers. When specific mobility events occur (such as cell quality thresholds being crossed), the system immediately generates measurement reports, transforming the reporting mechanism from time-driven to event-driven. This reduces response time while managing complexity through selective reporting only when events occur.
Solution Approach 2:
The system dynamically adjusts measurement reporting behavior based on mobility conditions. The reporting mechanism adapts its activity level according to the occurrence of mobility events, being more active when events occur and less active during stable conditions. This dynamic approach improves response time for mobility events while reducing overall processing complexity compared to continuous periodic reporting.
2Productivity
If flexible measurement reporting mechanisms are implemented, then resource allocation optimization is improved, but signaling overhead increases
Solution Approach 1:
The patent extracts and reports only the essential mobility measurement information triggered by specific events, rather than transmitting all measurement data continuously. By taking out only the relevant event-triggered measurement reports, the system optimizes resource allocation based on actual mobility needs while reducing signaling overhead compared to comprehensive continuous reporting.
Solution Approach 2:
The system performs partial measurement reporting by selectively reporting only when mobility events occur, rather than performing complete continuous reporting. This partial action approach provides sufficient information for resource allocation optimization while minimizing signaling overhead by avoiding redundant reports during stable mobility conditions.
