Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing communication systems lack support for recording a report of successful primary secondary cell (PSCell) addition or change, leading to potential failures and subsequent transmission service disruptions.
Innovation Solution
A method and apparatus for recording a report of successful PSCell addition or change by a terminal or network device, involving the reception of a configuration message with trigger condition configuration and subsequent recording of successful PSCell events based on elapsed time thresholds and timer conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the terminal does not record the report of successful PSCell addition or change, then the device complexity is reduced, but the reliability of transmission service is worsened due to potential failures and service disruptions
Solution Approach 1:
The terminal records the report of successful PSCell addition or change in advance based on trigger condition configuration received from the network device. This preliminary recording action ensures that when service disruption occurs, the recorded information can immediately be used for failure analysis and service recovery, thereby improving reliability without requiring complex real-time monitoring systems.
Solution Approach 2:
The system implements a feedback mechanism where the terminal records successful PSCell addition or change events and provides this information back to the network device. This feedback loop enables the network to monitor the status of PSCell operations and take corrective actions when failures occur, improving service reliability while maintaining manageable device complexity through structured information reporting.
2Reliability
If the terminal records the report of successful PSCell addition or change, then the reliability of transmission service is improved, but the use of energy is increased due to additional processing and recording operations
Solution Approach 1:
The terminal performs recording operations in advance based on pre-configured trigger conditions from the network device. This approach allows the terminal to record only when necessary (when trigger conditions are met) rather than continuously monitoring and recording, thereby improving service reliability while minimizing energy consumption by avoiding unnecessary recording operations.
Solution Approach 2:
The system changes the parameter of recording timing from continuous to event-driven based on trigger condition configuration. By adjusting when recording occurs (only when specific conditions are met), the system improves reliability through comprehensive event tracking while reducing energy consumption by avoiding constant monitoring and recording operations.
3Loss of time
If the terminal waits for failure detection before recording, then the device complexity is reduced, but the loss of time is increased due to delayed recording and service recovery
Solution Approach 1:
The terminal records successful PSCell addition or change events in advance based on trigger condition configuration, rather than waiting for failure detection. This preliminary recording ensures that when failures occur, the necessary information is already available for immediate analysis and service recovery, reducing time loss without requiring complex real-time failure detection systems.
Solution Approach 2:
The system maintains continuous recording capability triggered by specific events (PSCell addition or change) rather than intermittent failure detection. This continuous useful action ensures that recording is always ready when needed, reducing time loss for service recovery while maintaining manageable device complexity through event-driven operation.
