Flow measurement method for mobile network

The invention relates to the technical field of measurement of flow of a mobile network, and discloses a flow measurement method for the mobile network. The provided method measures and corrects the flow transmitted by the mobile network (2) through a mobile network flow measurement system (3), that is, a source end and target end joint monitoring mode is adopted to calculate the flow of a mobile terminal. The method comprises the step of calibrating flow data by a flow data calibration method and a flow data acquisition, analysis and counting method. The method provided by the invention can carry out full-coverage detection on the mobile terminal flow of three networks, the mobile network, the China Unicom network and the telecommunication network, so that precise counting of the data flow actually used by a customer from a user terminal is realized; by comparison with charged data of an operator, counting calibration and supervision of a mobile operator charging system are realized; therefore, a basis can be provided for detection of mobile network flow charging devices in all places by a counting technology mechanism, and the legal interest of the customer can be maintained.
