The invention relates to a telecommunication network signaling safety active protection method. By carrying out multidimensional integrated dynamic equivalent transformation on borne protocol types, call identification, carried parameters and transmission channels of signaling data, control signaling related in one call or different calls loses the similarity and the definiteness thereof in a time-space domain, and diversification, dynamism and randomization are presented, so that the active protection capability aiming at signaling attacks is formed. According to the invention, network attack behaviors or attack early-stage preparation behaviors with the purpose of obtaining network circumstance information and stealing user's privacy information can be discovered in advance and prevented well, and on the premise that a signaling protocol format standard is not changed, a signaling data multilayer dynamic equivalent transformation mechanism is introduced, so that the signaling data is enabled to present the irregularity and the jumping performance in the time-space domain to a third party except double sides of communication, the difficulty of intercepting, capturing, accurately recombining and restoring the signaling information is increased for network attackers, and the purpose of improving the telecommunication network signaling safety protection capability is achieved.
