In some embodiments, fig. 1 illustrates one configuration of the perception system. As shown in fig. 1, the perception system comprises: network management equipment 101, a central aware network element 102, at least one edge aware network element 103 and at least one aware base station 104.
Wherein the network management device 101 is in communication connection with the central aware network element 102. The central aware network element 102 is communicatively connected to at least one edge aware network element 103. The central aware network element 102 is communicatively coupled to at least one aware base station 104. Each edge aware network element 103 of the at least one edge aware network element 103 is communicatively connected to a part of the at least one aware base station 104.
In the present application, the network management device is configured to: and determining a target perception network element based on the perception requirement. And sending the identification of the target sensing network element to the central sensing network element.
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. The target sensing network element is at least one target edge sensing network element connected with the central sensing network element or the target sensing base station.
Alternatively, when the target sensing base station is one and the target edge sensing network elements connected to the target sensing base station are plural, the network management device 101 may select one target edge sensing network element from the plural target edge sensing network elements as the target sensing network element. When there are multiple target sensing base stations and each target sensing base station can individually meet the sensing requirement, the network management device 101 may select one target edge sensing network element from multiple target edge sensing network elements connected by the multiple target sensing base stations as the target sensing network element. When the base station capabilities of the plurality of sensing base stations 104 jointly meet the sensing requirement, the plurality of sensing base stations 104 can form a target sensing base station combination, and one edge sensing network element 103 connected with the target sensing base station combination is determined as the target sensing network element. When the plurality of sensing base stations 104 jointly meet the sensing requirement and the target edge sensing network elements connected by the plurality of sensing base stations 104 are multiple (i.e. the target sensing base stations are multiple), the network management device 101 determines the plurality of target edge sensing network elements as target sensing network elements. Specifically, the network management device 101 may determine, based on the sensing requirement and the access network configuration information of the sensing network element, a target sensing network element whose base station capability meets the sensing requirement, and send an identifier of the target sensing network element to the central sensing network element 102, so that the central sensing network element 102 sends a network element sensing activation message to the target sensing network element.
In this way, the network management device stores the access network configuration information of the central awareness network element 102 and the at least one edge awareness network element 103, and the network management device 101 does not interact with other devices, so that the privacy of information in the network management device 101 is ensured.
Optionally, the access network configuration information includes an identification of the perceived base station 104 to which each edge perceived network element 103 is connected, a perceived range (may also be referred to as coverage) and perceived capability of each perceived base station 104, an identification of all edge perceived network elements 103 to which the central perceived network element 102 is connected, and an identification of all perceived base stations 104.
Optionally, when determining the target sensing network element, the network management device 101 may determine the target sensing base station according to the coverage area and sensing capability of the sensing cell of the sensing base station 104, and determine the connected target sensing network element (the central sensing network element 102 or at least one target edge sensing network element) according to the target sensing base station, so when sending the identifier of the target sensing network element to the central sensing network element 102, may also send the identifier of the target sensing base station and the identifier of the corresponding sensing cell in the target sensing base station to the central sensing network element 102.
Optionally, because the access network configuration information includes coverage and sensing capability of the sensing cell in the sensing base station 104 connected to each sensing network element (the central sensing network element 102 or the edge sensing network element 103), the network management device 101 may determine, through the access network configuration information, a target sensing network element that meets the sensing requirement.

Illustratively, the network management device 101 includes: an access network configuration information receiving and storing unit 201, a query receiving unit 202, a matching selection processing unit 203, and a query feedback unit 204.
The access network configuration information receiving and storing unit 201 is configured to receive and store the access network configuration information of each of the edge aware network element 103 and the center aware network element 102 in itself. The access network configuration information is information of a sensing base station 104 communicatively connected to the edge sensing network element 103 or the center sensing network element 102, for example, the number of cells of the sensing base station, cell identification, coverage area of the cells, sensing capability of the cells, and the like. Table 1 shows a schematic representation of access network configuration information stored by the network management device 101.

SFc1 is a central sensing network element 102, and since the sensing base station 104 communicatively connected to the edge sensing network element 103 is also communicatively connected to the central sensing network element 102, the cells of SFc1 include the cells of SFd1 and SFd2, and the sensing capability of SFc1 is the sum of the sensing capabilities of all the cells.
Optionally, the network management device 101 may directly receive the access network configuration information reported by the edge-aware network element 103, or the edge-aware network element 103 may send the access network configuration information to the center-aware network element 102, where the center-aware network element 102 sends the access network configuration information to the network management device 101.
The query receiving unit 202 is configured to receive a query instruction (or signaling) sent by the central aware network element 102, and extract a perceived need from the query instruction.
