METHOD AND DEVICE FOR TRANSMITTING DATA

摘要

The present invention discloses a data transmission method and apparatus, and relates to the technical field of communication networks. In a data transmission process, different quality of service parameters may be flexibly adopted to transmit data, to flexibly adopt different download modes to download a media file, such that the video quality is improved and the network bandwidth resources are saved, or the media content may be smoothly played in real time to improve the user experience. According to the present invention, when transmitting data by using a first radio bearer, 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; the UE transmits a part of the data which has not been transmitted by using the second radio bearer. The solutions provided by the embodiments of the present invention are suitable to be adopted during switch between an adaptive streaming mode and a progressive download mode.
