The invention relates to a flow type pseudo base-station tracking and positioning method and system, wherein the method comprises the following steps of: S1, obtaining short message data by a mobile terminal; S2, judging whether the short message data satisfies a pre-set condition or not, if so, ending a process, and otherwise, executing the step S3; S3, sending the short message data marked as a suspected pseudo base station to a server side; S4, receiving a judgement result whether the suspected pseudo base station is a pseudo base station or not fed back by the server side and generated according to the short message data of the suspected pseudo base station, if so, executing the step S5, and otherwise, ending the process; and S5, outputting alarm information, and intercepting the short message data sent by the pseudo base station. The invention provides the system, which can analyze and position the pseudo base station only by utilizing a few computing resources; and, due to a mobile cloud computing technology, rapid information processing, analysis of the distribution condition of pseudo base stations, early warning, forecasting, and tracking and positioning of the movement locus of the pseudo base stations can be realized.
