In this paper, the possibility of a UE (User Equipment) incarceration attack using RRCRejecet and RRCRelease in 5G SNPN (Standalone Non-Public Network) is analyzed based on the 3GPP standard document. First, the cell selection and reselection procedures of the UE are analyzed, and then the processing process of the false base station and the UE before and after transmission of RRCReject and RRCRelease is analyzed. As a result of the analysis, it is possible that the false base station that transmits a strong signal causes the victim UE to establish an RRC connection to the false base station itself. In addition, if the false base station transmits an RRCReject message without integrity protection in response to the victim UE's attempt to establish an RRC connection, it is determined that the victim UE can continue to stay in the RRC connection attempt process. On the other hand, it is determined that it is impossible to incarcerate the victim UE by inducing an attempt to establish an RRC connection to another false base station using RRCRelease.

본 논문에서는 청소로봇의 주행에 관해 연구되어지고 있는 이론적인 제어알고리즘이 갖는 주행오차저감방법에 관해 연구하였다. 청소로봇의 양 바퀴의 속도에 따라 그려지는 이상적인 회전반경과 실제 실험을 통해 그려지는 회전반경은 다르다. 이는 청소로봇이 주행 시 나타나는 오차가 원인이다. 많은 이론적인 제어알고리즘이 청소로봇의 주행에 잘 적용되기 위해 주행 시 나타나는 오차를 수정하거나 보상해야 한다. 본 연구에서는 이상적인 회전반경과 실험을 통해 얻은 회전반경의 비교를 통해 오차와 회전반경을 구하고 이를 주행에 적용하고자 한다.
