Multi-Connectivity Path Selection Using Dual Data Buffer Thresholds

The patent introduces multiple uplink data split thresholds (first threshold and second threshold) instead of a single threshold, allowing the system to adapt to varying data buffer levels. When the data buffer level exceeds the first threshold, the UE activates multiple connectivity paths; when it falls below the second threshold, the UE deactivates secondary paths. This multi-parameter approach resolves the contradiction by maintaining simple threshold-based logic while improving adaptability to different network conditions and data amounts.

The patent implements dynamic path activation and deactivation based on real-time data buffer levels. The UE monitors its data buffer and compares it against configured thresholds to dynamically adjust the number of active connectivity paths. When data is abundant, multiple paths are activated to maximize throughput; when data is scarce, secondary paths are deactivated to reduce power consumption and signaling overhead. This dynamic adaptation resolves the contradiction between bandwidth utilization and energy efficiency.

The patent uses multiple thresholds (first threshold for activation, second threshold for deactivation) to control secondary path activation. By setting appropriate threshold values, the system ensures that secondary paths are only activated when there is sufficient data to justify the overhead, and deactivated when data amounts are small. This threshold-based control mechanism resolves the contradiction by providing redundancy only when beneficial, thereby reducing unnecessary signaling overhead and simplifying system operation.
