Abstract: Methods, systems, and apparatus for rate control are provided. In one aspect, a rate control method includes: receiving, by a control device, a connection establishment request from a terminal, the connection establishment request being for establishing a connection for the terminal to transmit data, and sending, by the control device, rate control time management information to a data sending device. The data sending device is configured to perform rate control over the data sent through the connection based on the time management information. The ratio control time management information includes start time indication information of a rate control time unit used for rate control, and the start time indication information indicates a start time of the rate control time unit.
