Terminal Environment Sensing for Handover Reliability

The patent segments the information processing by introducing a separate terminal device that independently performs positioning and environment sensing operations. The terminal device processes terminal related information (second information) separately from the network side device processing base station information (first information), then combines both for handover decisions. This segmentation allows each device to operate with appropriate complexity while achieving reliable communication through integrated information.

The terminal device acts as an intermediary between the network side device and the handover decision-making process. It receives requests from the network side device, performs positioning and environment sensing using terminal related information, and returns results that enhance the overall decision reliability. This intermediary role enables the system to incorporate terminal-specific contextual information without overwhelming the network side device with processing complexity.

The terminal device performs positioning and environment sensing operations in advance based on requests from the network side device, before handover decisions are finalized. By preparing terminal related information proactively, the system ensures high measurement precision is available when needed, while allowing the terminal to return to lower-power states between operations. The network side device controls when these energy-intensive operations occur through structured request-response protocols.

The system implements periodic positioning and environment sensing operations triggered by network side device requests rather than continuous operation. The terminal device performs measurements at specific intervals or events (such as potential handover scenarios), maintaining measurement precision when required while conserving energy during normal operation. This periodic approach balances accuracy requirements with energy constraints.
