The invention relates to an LTE network interception method and system, and the method comprises the steps that a base station module of a pseudo base station receives a first message from a terminal,generates a second message after processing, and transmits the second message to a terminal module of the pseudo base station; the terminal module of the pseudo base station receives the second message and forwards the second message to an operator LTE network; the base station module is used for receiving a third message from an operator LTE network and forwarding the third message to the pseudobase station; and the base station module of the pseudo base station receives the third message, modifies the content corresponding to the non-NAS signaling part according to the parameters of the pseudo base station, generates a fourth message after processing, and sends the fourth message to the terminal. According to the invention, the analysis failure process of the pseudo base station to thesecurity NAS is avoided th
