Title:
DATA TRANSMISSION METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/119195
Kind Code:
A1
Abstract:
Disclosed by the present application are a data transmission method and device, which can reduce the transmission delay of data packet transmission and improve the reliability of data packet transmission, and can, after the transmission of a data packet of a bearer has failed, ensure, to the greatest possible extent, that subsequent data packets are successfully transmitted, meeting the requirements of IIOT and other special services with regard to packet loss. In the present application, it is determined whether a timer related to the survival time corresponding to the data packet of a specific bearer is running; if at least one of said timers is running, then special processing is performed on the data packet of the specific bearer.
