A high-accuracy positioning method and a corresponding positioning system and positioning terminal are provided, and may be used in the field of intelligent vehicle technologies. In this positioning method, a real-time kinematics (RTK) positioning technology and a multi-receiver constraint MRC positioning technology are used to determine a location of a to-be-positioned target. In this positioning method, an RTK error correction model and an MRC error correction model may be preconstructed according to a big data technology. The RTK error correction model is used to provide a correction value for an original detection value obtained based on the RTK positioning technology. The MRC error correction model is used to provide a correction value for an original detection value obtained based on the MRC positioning technology. Then, the correction values are used to calculate the location of the to-be-positioned target.

This application provides a troubleshooting method and apparatus. The troubleshooting method includes obtaining key performance indicator (KPI) information of each service processor in a monitored network element; determining a faulty object according to the KPI information; determining a troubleshooting policy according to the faulty object; and sending the troubleshooting policy to a management unit in a network function virtualization (NFV) system, so that the management unit uses the troubleshooting policy to perform troubleshooting. Using the method or apparatus in this application, a problem of relatively low precision in fault locating according to a heartbeat message of a network element can be resolved.
