—In recent years, global cellular network service is being changed rapidly to LTE. However, the fast introduction of LTE has been going with not enough research about security threat so it could have many kinds of vulnerability. Therefore, the research about security threat on 4G network is ongoing in many countries. Particularly, in the situation where domestic subscribers are increasing rapidly, the security threats which are hindering stability and usability could make a fatal effect on many users. 4G network should consider the feature of mobile network to keep 4G network stable. Because mobile network has limited radio resources, it releases the radio resource which is not used in selected time and reallocates when requesting the data transmission. Many signaling messages are transferred in the network entities to allocate or release the radio resource. In this paper, it will introduce the technology to detect signaling DoS traffic hindering the stability and usability of network entities managing the radio resources by huge signaling message from the repetitive wireless connection/release message.
