Dynamic Connection Identifier Assignment for D2D Resource Efficiency

The patent implements dynamic connection identifier assignment where the system transitions from fixed CID allocation to flexible reassignment based on real-time connection activity. When a connection becomes inactive, its CID can be reassigned to active connections, making the resource allocation dynamic rather than static. This resolves the contradiction by maintaining reliable connection establishment through structured reassignment procedures while eliminating wireless resource waste through active monitoring and reallocation of CIDs.

The system changes the state parameter of connection identifiers from permanently assigned to temporarily assigned based on connection activity status. By monitoring data transmission characteristics and connection usage patterns, the system adjusts CID allocation parameters dynamically. This allows the same CID pool to serve multiple connections over time, reducing resource waste while maintaining connection reliability through proper state tracking and reassignment protocols.

The patent makes connection identifiers universal by allowing the same CID to be reused across different connections at different times. Instead of requiring unique CIDs for each potential connection, the system designs CIDs to serve multiple connections sequentially. This increases connection capacity without proportionally increasing the total number of CIDs needed, and reduces management complexity through systematic reassignment rules rather than tracking numerous permanent assignments.

The system implements a discard and recover mechanism for connection identifiers. When a connection becomes inactive or is terminated, its CID is discarded from active use and recovered back to the pool of available identifiers for reallocation. This approach increases connection capacity by enabling identifier reuse while simplifying management through automated lifecycle tracking of CIDs based on connection states rather than manual assignment tracking.

The patent implements a self-service mechanism where the system automatically monitors connection activity and performs CID reassignment without requiring complex external control algorithms. The connection management entity tracks data transmission characteristics and autonomously decides when to reassign CIDs based on predefined criteria such as inactivity thresholds. This improves resource utilization efficiency through automated dynamic reassignment while limiting algorithm complexity by using simple, rule-based decision logic rather than complex optimization algorithms.

The system employs feedback mechanisms where connection activity status is continuously monitored and fed back to the CID assignment function. Based on this feedback regarding data transmission patterns and connection activity, the system adjusts CID allocation dynamically. This improves resource efficiency by responding to actual usage conditions while managing algorithm complexity through feedback-driven incremental adjustments rather than requiring complex predictive algorithms. The feedback loop enables adaptive resource allocation with relatively simple control logic.
