Abstract: A driving control method and apparatus are provided. The method may be applied to the intelligent vehicle field such as intelligent driving/automatic driving. The driving control method includes, after calculating a conventional path in a conventional map, the driving control apparatus searches a high-definition map for a high-definition path that matches the conventional path, and if yes, performs real-time navigation broadcast by using the conventional path, and performs automatic driving by using the found high-definition path. The driving control method and apparatus use advantages of the conventional map, for example, rich road sections and updated real-time traffic information, a more proper calculated conventional path, and a better effect of real-time navigation broadcast, and implement automatic vehicle driving by using a high-definition path, to reduce user operations, thereby improving user experience.

Abstract: This application provides a scheduling method and apparatus. The method includes: a network device uses a scheduling model applicable to K users for one or more times, and determines a scheduled terminal device based on scheduling weights output by the scheduling model for one or more times. Each time the scheduling model is used, status information of K terminal devices in n to-be-scheduled terminal devices is input to the scheduling model, and the scheduling model outputs scheduling weights respectively corresponding to the K terminal devices, where K is an integer greater than 1, and n is an integer greater than K. Therefore, regardless of a quantity of to-be-scheduled terminal devices in a communication system, the network device may reuse the scheduling model without re-establishing a scheduling model, so that the scheduling model is expandable and applicable to scenarios in which quantities of to-be-scheduled terminal devices are different.
