Description

Sensing methods and devices This application claims priority to Chinese patent application filed on October 31, 2024, with application number 202411554155.X and entitled "Sensing Method and Apparatus", the entire contents of which are incorporated herein by reference. Technical Field This application relates to the field of communication technology, and more specifically, to a sensing method and apparatus. Background Technology With the development and advancement of communication technology, in future cellular networks, communication devices (e.g., base stations) will not only be able to achieve the Internet of Things, but also possess sensing capabilities. Enabling technologies that enable the coexistence, mutual assistance, or mutual benefit of communication and sensing functions can be termed integrated sensing and communication (ISAC). As research on ISAC deepens in academia and industry, using radio frequency signals from communication systems for sensing is becoming an increasingly popular research direction. For example, application function network elements can send sensing requests to request sensing services. However, how to effectively process sensing requests is an urgent problem to be solved. Summary of the Invention This application provides a sensing method and apparatus. By determining whether a new sensing request meets certain conditions, it determines whether to reuse the sensing results of an existing sensing task, thereby effectively processing the sensing request. Firstly, a sensing method is provided. The method provided in the first aspect is applied to a first sensing network element. Unless otherwise specified, the first sensing network element in this application can be a core network device, a component within the core network device (e.g., a processor, apparatus, circuit, chip, or chip system), or a logic module or software capable of implementing all or part of the functions of the core network device. For ease of description, the following description uses a first sensing network element as an example. For example, the first sensing network element can be responsible for sensing control. For instance, the first sensing network element can serve as a control plane network element for sensing. The first sensing network element can be called a sensing control function (SCF). In future communication systems, the first sensing network element may have other names, which are not limited in this application. The method includes: receiving a first sensing request from an application function network element, the first sensing request being used to request a first sensing result; if the first sensing request satisfies a first condition, sending first information to the application function network element, the first information being used to indicate a second sensing result; or, if the first sensing request does not satisfy the first condition, processing the first sensing request; wherein the first condition is a condition for reusing the second sensing result, and the second sensing result is a sensing result of a second sensing task. The first sensing network element receives the first sensing request from the application function network element. This can be done directly from the application function network element or indirectly through other network elements. For example, the first sensing network element can receive the first sensing request from the application function network element through the network exposure function (NEF); that is, the NEF can receive the first sensing request from the application function network element and can also send the first sensing request to the first sensing network element. Based on the above scheme, SCF can flexibly handle different sensing requests in different ways when an existing sensing task is being executed. For example, if sensing request #1 meets the first condition, the sensing results of the existing sensing task can be reused, thereby avoiding the overhead and latency of sensing and measuring again. Conversely, if sensing request #2 does not meet the first condition, it can be further processed. In some implementations, the first information includes the second sensing result; or, the first information includes first indication information, which is used to indicate the reuse of the second sensing result. Based on the above scheme, the first information can directly indicate the second sensing result, thereby realizing the transmission of the second sensing result. The first information can also indicate the reuse of the second sensing result. AF can determine the second sensing result from the pre-obtained sensing results, thereby reducing the transmission overhead of the second sensing result. In some implementations, the first sensing request is used to indicate at least one of a first service type, a first quality of service (QoS) requirement, or a first sensing area; wherein the first condition includes at least one of the
