If the core network device selects secondary access network devices or terminal devices for sensing operations, then sensing operations can be performed, but the selection accuracy deteriorates because the core network device cannot accurately know the distribution of other terminal devices or access network devices around the terminal device
Solution Approach 1:
The terminal device feeds back assistance information to the core network device, enabling the core network device to accurately determine the distribution of terminal devices and access network devices around the terminal device, thereby improving sensing node selection accuracy
Solution Approach 2:
The terminal device acts as an intermediary that provides assistance information to the core network device, bridging the information gap between the core network device and the distributed terminal devices, enabling accurate sensing node selection
