Background

Typical application scenarios of the communication perception technology include automatic driving, unmanned aerial vehicle supervision, train channel foreign matter detection, health monitoring and the like, and most of the scenarios only need partial base stations to execute perception. For example, the perception of foreign matters on a train track only needs to be participated in by base stations along the train track, and the perception of the unmanned aerial vehicle only needs to be participated in by base stations in the flight area of the unmanned aerial vehicle. If all the base stations participate in sensing, a large amount of data is transmitted to the core network, so that pressure is caused to the network elements of the core network and the transmission network, and the transmission and processing efficiency is affected. In addition, there may be both a base station supporting communication and sensing and a base station supporting only communication in the same area, and if the core network element sends a sensing request to all base stations, the base stations not supporting sensing may cause errors due to the inability to recognize the request, resulting in additional performance and signaling overhead. Meanwhile, if the communication load of the base station is heavy, enough resources may not be available to perform sensing, so that on one hand, sensing performance is affected, and on the other hand, communication performance is affected.

Typical application scenarios of the communication sensing technology include automatic driving, unmanned aerial vehicle supervision, train channel foreign matter detection, health monitoring and the like, and most of the scenarios only need partial base stations and/or terminals to execute sensing. For example, the perception of foreign matters on a train track only needs to be participated in by base stations along the train track, and the perception of the unmanned aerial vehicle only needs to be participated in by base stations in the flight area of the unmanned aerial vehicle. If all the base stations participate in sensing, a large amount of data is transmitted to the core network, so that pressure is caused to the network elements of the core network and the transmission network, and the transmission and processing efficiency is affected. In addition, there may be both a base station supporting communication and sensing and a base station supporting only communication in the same area, and if the core network element sends a sensing request to all base stations, the base stations not supporting sensing may cause errors due to the inability to recognize the request, resulting in additional performance and signaling overhead. Meanwhile, if the communication load of the base station is heavy, enough resources may not be available to perform sensing, so that on one hand, sensing performance is affected, and on the other hand, communication performance is affected.

For this reason, the following technical solutions of the embodiments of the present application are proposed. According to the technical scheme, the base station used for sensing (simply referred to as sensing base station) is selected based on at least one of the base station capability, the area and the sensing service, so that the problem of base station selection in the area sensing scene is solved, and the scheme can be used for a scene of a terminal executing sensing.
