Data distribution service communication method

The invention relates to a data distribution service communication method. Firstly, a publisher and a subscriber are generated, and the subscriber sends needed data types to a data theme generation module. The data theme generation module establishes a data theme for the publisher according to the data types needed by the subscriber. The types of the data theme comprise remote measurement, remote signaling, sequence remote measurement and sequence remote signaling. When the subscriber need single data at one time, a remote measurement or remote signaling data theme is established for the publisher. When the subscriber need a plurality of data at one time, a sequence remote measurement or sequence remote signaling data theme is established for the publisher. The transmission efficiency is raised through the subscription mode, and the subscriber can subscribe all the remote measurement of a certain line for one time, and can subscribe specific remote measurement of all the lines for one time for comparison of maximum values. Flexibility is raised for the transmission mode, and the problems are solved that only a data can be transmitted for one time, thus the transmission speed is slow, and the efficiency is low in the prior art.
