The target sensing base station is a sensing base station with the base station capability meeting the sensing requirement in at least one sensing base station.

Specifically, when the required resource amount of the perceived need is greater than a first preset threshold, the network management device may determine that the perceived need is a heavy load perceived need. When the sensing requirement is a heavy load sensing requirement, the network management equipment can determine an edge sensing network element which can process the sensing requirement as a to-be-selected sensing network element from a plurality of edge sensing network elements, and send the identification of the to-be-selected sensing network element to the AMF.

Specifically, after the first sensing data is obtained, the target sensing base station may directly send the first sensing data to the target sensing network element, or may process the first sensing data, so as to send the processed first sensing data to the target sensing network element.

From the above, the target-aware base station may receive the base-station-aware activation message sent by the target-aware network element, and because the base-station-aware activation message is generated by the target-aware network element, the target-aware base station may process the awareness requirement.
