Description

This application claims priority to Chinese Patent Application No. 202310940648.6, filed with the China National Intellectual Property Administration on July 28, 2023 and entitled "COMMUNICATION SYSTEM, NETWORKING METHOD, AND RELATED APPARATUS", which is incorporated herein by reference in its entirety. TECHNICAL FIELD This application relates to the field of communication technologies, and in particular, to a communication system, a networking method, and a related apparatus. BACKGROUND With continuous development of global communication technologies, wireless communication technologies have surpassed wired communication technologies in a development speed and application, and present a booming development trend. Smart devices such as smart transportation devices, smart home devices, and robots are gradually entering daily life of people. The smart devices may be networked by using a wireless communication technology to form a wireless communication network. Networking modes of the wireless communication network may include a networking mode of one primary node and a plurality of secondary nodes, and the like. The networking mode is a networking mode in which the secondary node discovers the primary node for communication connection. However, in consideration of costs and flexibility, it is usually difficult to preset an association configuration of the primary node in the secondary node before delivery. In addition, in an environment like a parking lot, a production and maintenance workshop, or a shopping mall, there are a large quantity of smart devices in same space covered by wireless signals. If the plurality of smart devices further include a primary node other than a target primary node to which a secondary node is to be connected, the primary node interferes with a connection between the secondary node and the target primary node. SUMMARY This application provides a communication system, a networking method, and a related apparatus. In this way, in a networking scenario in which a secondary node discovers a primary node for a communication connection, interference from another redundant primary node can be eliminated. Therefore, the secondary node can determine the primary node to which the communication connection is to be established, to improve certainty and efficiency of the communication connection. According to a first aspect, this application provides a communication system. The communication system includes a primary node and a secondary node, the secondary node is a node providing service content or a service, the primary node is a node using the service content or the service, and feature information of the secondary node is configured on the primary node. The primary node sends a broadcast message, and the broadcast message indicates the feature information. The secondary node receives the broadcast message. The secondary node sends a connection request message to the primary node based on the feature information indicated by the broadcast message. The primary node receives the connection request message, and establishes a communication connection to the secondary node based on the connection request message. Optionally, the secondary node does not broadcast the feature information. The foregoing solution is applied to a networking scenario in which the secondary node discovers the primary node to perform the communication connection (which is embodied by a feature that the primary node sends the broadcast message, and the secondary node responds to the broadcast message to make a request to the primary node to establish the communication connection). In the networking scenario, an existing implementation solution cannot resolve a problem of how to accurately select the primary node to establish the communication connection after the secondary node receives broadcast messages of a plurality of primary nodes. In this solution, the feature information of the secondary node is indicated in the broadcast message of the primary node. In this way, the secondary node learns that the broadcast message is a message to which the secondary node needs to respond, and therefore filters out a broadcast message of another primary node. This can accurately implement the communication connection between the secondary node and the primary node, and reduce interference of the another primary node. In a possible implementation, the primary node has a human-computer interaction interface for configuring the feature information, and the secondary node does not have a human-computer interaction interface. In the foregoing solution, because the primary node has the human-computer interaction interface, the feature information of the secondary node may be configured on the primary node through the human-computer interaction interface. In this way, the primary node can add feature indication information of the secondary node to the broadcast message. In addition, because the secondary node does not have the human
