And the reference is made to the reconfiguration of the directional flow template data for the operator, so that the problem of non-directional flow counting errors in the process of using the directional flow service by the user is reduced. The method and the device capture data traffic consumption through a local and remote cross-platform (android, iOS) mobile phone 4G network, analyze whether the data traffic is in accordance with a directional traffic template or not by analyzing information combination modes such as a transmission layer, a data link layer and an application layer of a data packet to obtain IP addresses, port numbers and domain names, give a traffic IP address hit parameter and network data information which is not in the directional traffic template, and improve the accuracy of the directional traffic-free service.
