RLC AM Buffer Discard Timing for Missing Sequence Numbers

The patent applies preliminary action by establishing a discard timer before data is permanently retained in the buffer. When the timer expires without receiving an ACK, the data is automatically discarded, preventing indefinite buffer occupancy. This resolves the contradiction by proactively managing buffer resources while maintaining reliability through the timer-based discard mechanism.

The patent applies dynamics by making the buffer retention period adaptive through the discard timer mechanism. The timer duration can be dynamically adjusted based on network conditions and data characteristics, allowing the system to balance between retaining data for reliability and discarding data for efficiency. This dynamic approach resolves the contradiction by adapting the retention policy rather than using a fixed strategy.

The patent applies self-service by implementing a discard timer that automatically manages data retention without requiring complex external control mechanisms. The timer self-starts, self-counts, and self-triggers data discard when expired, reducing the need for complex buffer management logic. This self-service approach resolves the contradiction by simplifying the control mechanism while maintaining efficient data handling.
