Title:
DATA TRANSMISSION METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/014902
Kind Code:
A1
Abstract:
Disclosed in the embodiments of the present disclosure are a data transmission method and device, belonging to the field of communication technologies. The method comprises: when a DRB remapping event is detected during data transmission of a target data stream, determining whether a target DRB to be switched to supports sequential data transmission; if the target DRB does not support sequential data transmission, transmitting, by means of an original DRB, data packets of the target data stream which have been delivered to the original DRB, and transmitting, by means of the target DRB, data packets of the target data stream which have not been delivered to the original DRB; if the target DRB supports sequential data transmission, transmitting the data packets of the target data stream on the basis of a transmission mode without changing the sequence of the data packets. Compared to the prior art, the method provided by the embodiments of the present disclosure can improve communication quality while ensuring the transmission sequence of data packets with regard to the DRB which supports sequential data transmission.
