Proximity-Based PSM Triggering for MTC UE Battery Management

The patent implements dynamic network connectivity management by transitioning the MTC UE between connected and disconnected states based on proximity conditions. When proximity is detected, the UE enters a disconnected state to save battery while maintaining the ability to quickly reconnect when needed, making the connectivity state adaptive rather than static.

The patent uses proximity detection as a preliminary trigger to initiate detach or power-saving mode procedures before actual data transmission is needed. By detecting proximity in advance and proactively managing connectivity state, the system prevents unnecessary battery consumption while ensuring service readiness when proximity-based communication is actually required.

The patent implements periodic proximity detection followed by batched or conditional attach/detach procedures rather than continuous real-time state changes. By periodically checking proximity conditions and only triggering network procedures when necessary, the system reduces signaling overhead while maintaining adaptability for direct communication when needed.

The MTC UE autonomously determines when to perform attach or detach procedures based on local proximity detection, eliminating the need for continuous network-controlled connectivity management. This self-service approach reduces signaling overhead by allowing the UE to independently manage its connectivity state based on actual service needs.

The patent implements feedback mechanisms where the UE monitors proximity conditions and network state, and adjusts its connectivity mode accordingly. The system continuously feedbacks proximity information to trigger appropriate connectivity state changes, ensuring that the UE transitions from power-saving mode to connected mode when proximity-based communication is detected, thus maintaining network responsiveness when needed.

The patent applies preliminary anti-action by preparing the UE to quickly exit power-saving mode when proximity conditions are detected. The system pre-configures the UE with the ability to rapidly transition from disconnected to connected state, counteracting the potential delay in network responsiveness that would result from entering power-saving mode.
