METHOD AND DEVICE FOR TRANSMITTING DATA

摘要

The present invention relates to the technical field of communication networks, and disclosed are a method and device for transmitting data. Data can be transmitted flexibly by using different quality of service parameters in a data transmission process, thereby using different download modes to download a media file, and improving the quality of a video and saving network bandwidth resources, or media content can be smoothly played in real time, and the user experience is improved. According to the present invention, in a process that a first radio bearer is used to transmit data, a UE receives radio resource control connection reconfiguration information sent by a base station; the UE obtains a second radio bearer according to the radio resource control connection reconfiguration information; the UE sends radio resource control connection reconfiguration completion information to the base station; and the UE uses the second radio bearer to transmit part of the data that is not transmitted. The solutions provided by embodiments of the present invention are applicable to be used in switching between an adaptive streaming mode and a progressive download mode.
