Abstract

The invention discloses a data extraction method. The method comprises: establishing a metainformation use state list according to the demand of a data application, wherein a corresponding relationship of the data application and the used metainformation is recorded in the metainformation use state list; determining metainformation needing to be analyzed during message analysis and metainformation contained in a data record corresponding to each data application according to the metainformation use state list; and when the demand of the data application to the metainformation changes, updating the metainformation use state list, and updating the metainformation contained in the data record corresponding to each data application according to the updated metainformation use state list. The data extraction method disclosed by the invention can be used for adaptively adjusting the data extraction metainformation based on the demand of the data application, fully improving the message analysis effective on the premise of not interrupting the data application, and reducing the storage space of the data record. The invention further discloses a data extraction device.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a data extraction method and device. Background technique [0002] When identifying mobile Internet applications, Deep Packet Inspection (DPI) technology is generally used for traffic collection. The method is to deploy DPI devices on network devices (such as GGSN network elements) in series or bypass mode. Above, data packets are obtained by mirroring and copying the original code stream flowing through the network device, and the DPI device completes the packet analysis of the 3-7 layers of the data packet network protocol, obtains meta information, generates records and performs subsequent processing, such as Business application identification, traffic management, user behavior analysis, etc. [0003] as attached figure 1 As shown, the data extraction system architecture usually includes: a data analysis module, a data storage module and a data acquisition mod...
