Summary:The invention relates to a mobile application-oriented traffic feature extraction method and a system. The method comprises the following steps of: acquiring data information on mobile equipment; preprocessing the data information; obtaining an application ID and constructing an application feature; performing ID feature recognition on the preprocessed data information based on the application features, and screening out data information which cannot be recognized; clustering the data information which cannot be identified by the application ID into a highly similar network flow set; extracting the longest common subsequence of the request message in each set, and removing all changed fields and irrelevant values in the longest common subsequence to obtain data structured features; and judging the final affiliation of the features according to the frequency of the network flow represented by the data structured features in different applications. According to the method, the application network flow can be ef
