Title:
DATA COMMUNICATION METHOD AND DATA COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/024250
Kind Code:
A1
Abstract:
Data communication method and system. The method comprises: a first terminal transmits, to a second terminal, first data, and upon completion of transmitting the first data, starts measuring a time value, wherein the first data comprises data to be processed (S11); the second terminal receives the first data, and upon completion of receiving the first data, starts measuring a time value (S12); when the time value obtained by the second terminal reaches a preconfigured value, the second terminal performs data processing on the data to be processed, and transmits, to a first terminal, second data generated after the data processing (S13); and when the time value obtained by the first terminal is in a valid range of a preconfigured value, the first terminal is permitted to start receiving the second data (S14). By adopting the scheme of the second terminal transmitting data in a fixed time interval and the first terminal receiving the data in another fixed time interval, the first terminal can identify data hijacking at an intermediate node even when the second data is received at the time T2 less than a frame waiting time (FWT).
