UE RRC Link Release for Bursty Traffic Power Saving

The patent implements dynamic RRC state management by introducing adaptive timer mechanisms that adjust theConnected state duration based on traffic patterns. The UE monitors data activity and dynamically transitions between RRC_CONNECTED and RRC_IDLE states, making the system flexible rather than static. This resolves the contradiction by allowing the UE to stay connected only as long as necessary for active traffic, reducing power consumption while maintaining responsiveness when needed.

The patent employs periodic traffic monitoring and timer-based state transitions. The UE uses inactivity timers that expire periodically to trigger state changes from CONNECTED to IDLE when no traffic is detected. This periodic action allows the system to balance between maintaining connection readiness and conserving energy, addressing the contradiction by introducing rhythmic evaluation of connection necessity rather than continuous connection maintenance.

The patent implements preliminary actions by configuring inactivity timers before state transitions occur. The UE starts monitoring traffic patterns and prepares for potential state changes in advance, rather than reacting abruptly to traffic conditions. This preliminary monitoring and timer configuration allows smoother transitions with reduced latency, as the system is already prepared to switch states when the timer expires, rather than requiring immediate decision-making at the moment of transition.

The patent uses feedback mechanisms where the UE continuously monitors data traffic patterns and adjusts its state transition behavior based on observed activity. The inactivity timer mechanism provides feedback about traffic conditions, and the UE uses this feedback to make informed decisions about when to transition states. This feedback loop optimizes transition timing to minimize unnecessary transitions and reduce associated latency, balancing power savings with performance requirements.

The patent optimizes power saving by adjusting timer parameters and state transition thresholds based on traffic characteristics. The inactivity timer duration and transition criteria are tuned to match bursty traffic patterns, allowing the UE to stay in CONNECTED state during active bursts and transition to IDLE during quiet periods. This parameter optimization achieves better power savings without requiring complex algorithms, maintaining relatively simple implementation while improving efficiency.

The patent implements self-service mechanisms where the UE autonomously manages its own RRC state transitions based on local traffic monitoring. The UE independently decides when to transition between CONNECTED and IDLE states using its own traffic observations and timer configurations, without requiring complex network-controlled management. This self-service approach reduces the need for sophisticated external control systems while achieving effective power optimization through locally-adapted state management.
