Data transmission method and apparatus, and system

Abstract

This application provides a data transmission method and apparatus, and a system, pertaining to the communication field. The method is applied to a receiving device and includes: starting a first timer corresponds to a first data bearer; receiving N pieces of data from a sending device, where the N pieces of data belong to a first data set that corresponds to the first data bearer, and N is a positive integer; and when the first timer expires, synchronously delivering the N pieces of data. Based on the method and the foregoing technical solution, the receiving device synchronously delivers data in a data set corresponding to the first timer when the first timer expires. This helps ensure stability of transmission delay of the data set, avoid the issue of significant jitter in transmission delay among different data, and prevent triggering a congestion control operation, thereby improving service experience for users.
