Title:
DATA TRANSMISSION METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/015111
Kind Code:
A1
Abstract:
Disclosed in an embodiment of the disclosure are a data transmission method and device, belonging to the technical field of communication. The method comprises: When it is detected that a DRB remapping event occurs during data transmission of a target data stream, determining whether a switched target DRB supports a sequential transmission of data; if the target DRB does not support sequential transmission of data, then transmitting, by an original DRB, a data packet of a target data stream that has been delivered to the original DRB, and transmitting, by the target DRB, a data packet of the target data stream that has not been delivered to the original DRB; if the target DRB supports the sequential transmission of data, then transmitting the data packet of the target data stream on the basis of a transmission manner that does not change the sequence of the data packet. With the method provided by the embodiment of the present disclosure, compared with the prior art, the communication quality can be improved while ensuring the data packet transmission sequence for the DRB supporting the sequential transmission of data.
