Conditional L1/L2 Mobility Triggers for 5G NR Handover Control

The patent implements dynamic mobility management by introducing condition-based triggers (Layer 1 and Layer 2 triggers) that adapt mobility parameters in real-time based on current network conditions, traffic load, and device capabilities. This allows the system to dynamically adjust handover thresholds, timing advances, and resource allocation rather than using static traditional mechanisms, thereby improving network efficiency while maintaining adaptability to heterogeneous environments.

The patent changes key mobility management parameters based on detected conditions. Specifically, it modifies handover thresholds, timing advance values, and resource allocation parameters according to Layer 1/Layer 2 trigger conditions, traffic load measurements, and device capability reports. This parameter adaptation enables optimal performance across diverse 5G NR scenarios including varying traffic types, channel conditions, and device capabilities.

The patent segments mobility management into distinct Layer 1 and Layer 2 trigger mechanisms, each handling specific aspects of mobility control. Layer 1 triggers deal with physical layer measurements and basic handover decisions, while Layer 2 triggers handle higher-layer resource allocation and coordination. This segmentation reduces overall system complexity by dividing the complex mobility management function into manageable, specialized subsystems with clearly defined interfaces.

The patent implements preliminary measurement and evaluation mechanisms that continuously monitor network conditions, device capabilities, and traffic patterns before mobility events occur. By pre-evaluating conditions and preparing appropriate responses in advance, the system avoids complex real-time decision-making during actual handovers, thereby improving resource utilization while keeping the active system complexity manageable through pre-computed mobility policies.
