Description

Mobile sensing method, mobile sensing system, source node and target node Technical Field The embodiment of the application relates to the field of wireless communication, in particular to a mobile sensing method, a mobile sensing system, a source node and a target node. Background With the widespread popularity of internet applications and wireless network devices, the demand for wireless communications has increased further. Future communication systems will be systems with integrated communication awareness, i.e. the communication system will have the ability to perceive measurements in addition to having a stronger communication capability. Communication awareness integrated systems may utilize transmission, reflection or scattering of radio waves to perceive a characterization environment for simultaneous localization and mapping (simultaneous localization AND MAPPING, SLAM) and the like. The radio resource control protocol (radio resource control, RRC) of the terminal device in the fifth generation mobile communication technology (5th generation mobile communication technology,5G) network is connected with 3 states, an idle state, an inactive state and a connected state. Mobility management of terminal equipment in an inactive state is carried out at a terminal equipment side, paging of the terminal equipment in the inactive state by a network side depends on an access network notification area (RAN notification area, RNA), and when a message needs to be transmitted to the terminal equipment at the network side, paging can be initiated. The network side needs to perform multi-beam paging in each of a plurality of cells in the RNA. Mobility management of terminal equipment in idle state is at terminal equipment side, paging of network side to idle state terminal equipment depends on tracking area (TRACKING AREA, TA), paging of network side needs to carry out paging of multiple beams in each of multiple cells corresponding to TA. Each TA contains a plurality of RNAs, and each RNA contains a plurality of cells. In the paging process, in one RNA or TA, the beams for paging in the cells other than the cell in which the terminal device is located are all invalid beams, which causes resource waste and extra signaling overhead. Disclosure of Invention The embodiment of the application provides a mobile sensing method, a mobile sensing system, a source node and a target node, which are applied to the field of wireless communication and are used for realizing mobile sensing management of terminal equipment. In a first aspect of the embodiment of the present application, a mobile sensing method is provided, in which a first node is a current maintenance node of a terminal device, and is configured to acquire, store, or update sensing information of the terminal device. When the channel quality between the first node and the terminal device is reduced or is below a certain threshold, the first node needs to find another node as a maintenance node of the terminal device. After the first node determines the second node meeting the transfer condition, the first node sends a transfer request to the second node to request the second node to serve as a maintenance node of the terminal equipment to perform perception maintenance on the terminal equipment, and at the moment, the first node is called a source node, and the second node is called a target node. The source node may include, in the transfer request sent to the target node, sensing information for performing sensing measurement on the terminal device, where the sensing information includes at least location information of the terminal device. Through the location information, the source node or the target node can locate the terminal device. In the embodiment of the application, the source node sends the transfer request to the target node, so that the target node can position the terminal equipment according to the perception information in the transfer request, thereby realizing the perception management of the terminal equipment. When the target node receives the paging message, the target node can locate the terminal equipment and page the terminal equipment, so that the generation of invalid beams is reduced, and resource waste and extra signaling overhead are avoided. In some alternative embodiments, the location information of the terminal device includes at least one of a coordinate location, a distance, a speed, an angle, and a movement direction of the terminal device. The location information may be location information of the terminal device with respect to the source node or location information of the terminal device with respect to the target node. In the embodiment of the application, the source node or the target node can locate the terminal equipment through the position information. Meanwhile, based on the position information, the source node or the target node has the function of performing sensing and positioning on the passive terminal e
