The central aware network element 102 is communicatively connected to a plurality of edge aware network elements 103. The central aware network element 102 is communicatively coupled to a plurality of aware base stations 104. Each edge aware network element 103 of the plurality of edge aware network elements 103 is communicatively connected to a part of the aware base stations 104 of the plurality of aware base stations 104.

The identity of the candidate perceived network element is sent to the central perceived network element 102.

The to-be-selected sensing network element is a target edge sensing network element connected with the central sensing network element 102 or the target sensing base station. 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.
