Terminal-Core Sensing Coordination for Accurate Network Measurements

The patent segments the sensing measurement data collection process into two independent parts: terminal-side data collection (first sensing measurement data) and core network device-side data collection (second sensing measurement data). Each side collects only the specific data types relevant to its capabilities, avoiding the need for one entity to collect all data types. This segmentation reduces system complexity while maintaining comprehensive sensing accuracy through the combination of both data sources.

The patent implements preliminary action by having the terminal and core network device independently collect their respective sensing measurement data in parallel before the data fusion stage. The terminal collects first sensing measurement data (such as signal strength, position information) while the core network device simultaneously collects second sensing measurement data (such as network load, interference levels). This parallel pre-collection approach eliminates sequential processing delays and reduces overall data processing time while ensuring comprehensive data coverage for accurate sensing results.

The patent introduces the core network device as an intermediary that assists the terminal in the sensing measurement data collection process. Instead of the terminal attempting to collect all types of sensing data independently, the terminal collects first sensing measurement data within its capabilities and requests additional second sensing measurement data from the core network device. The core network device acts as a mediator that provides complementary data (such as network-level measurements) that the terminal cannot obtain on its own. This intermediary approach ensures sensing service completeness while keeping terminal resource consumption within acceptable limits.
