¿µ¹® ³»¿ë¿ä¾à This technical report describes that the degradation of call quality and SINR on device occurring at the site when same PCI are allocated in the transfer station and adjacent areas by the same operating organization in the metropolitan area, such as Seoul Metro, and when the MOD3 design rule is not complied. The phenomenon is explained through DM log analysis of UE, and based on TR 36.902. This report explains PCI integrated management guide and MOD3 collision prevention process which have been verified by operating commercial networks since 2010.
