Abstract: A method and an apparatus for signal synchronization are disclosed. The method for signal synchronization includes: A self-synchronizing first terminal device broadcasts first synchronization information, determines whether the first terminal device and a second terminal device have implemented signal synchronization when receiving second synchronization information sent by the second terminal device, and determines, based on a determining result, whether to synchronize with the second terminal device. This reduces a probability of communication interruption caused by synchronization source switching by the first terminal device after the second terminal device performs synchronization by using the first terminal device as a synchronization source. The method for signal synchronization may be applied to scenarios such as the intelligent driving, intelligent connected vehicles, and internet of vehicles.

Abstract: A method for a protocol data unit (PDU) session includes a step of a first core network device obtaining a first message from a first server. The first core network device generates a first parameter based on the first message. A terminal device obtains a measurement result based on the first parameter and sends the measurement result to the first core network device. The first core network device obtains a second parameter based on the measurement result, and the second core network device configures the second parameter to dynamically adjust the PDU session based on location or time information with reference to the second parameter.
