The invention discloses a flow monitoring method based on a wireless public network communication way for a power distribution terminal. According to the method, flow statistics of a GPRS (General Packet Radio Service) wireless communication power distribution terminal is realized, the hourly communication flow, daily communication flow and monthly communication flow of the wireless power distribution terminal are mainly monitored, and history information about flow is recorded, so that the flow change process of the wireless power distribution terminal is reflected. By adopting the flow monitoring method based on the wireless public network communication way for the power distribution terminal provided by the invention, abnormal flow in an APN (Access Point Name) special line is analyzed, so that the problem of out of control of the GPRS communication flow of the power distribution terminal is solved, and references are provided for the analysis of the GPRS access quality and charge management of the power distribution terminal.
