In this paper, a research on the structure and the network configuration of the location register(LR), which database of new locations and service informations of subscribers according to the movement of subscribers in personal communication system(PCS). since the traditional PCS manages all the databases with the location informations as a centralized type. The service informations of the subscribers are centrally controlled by the HLR. So there have been the heavy signal traffic and the call setup delay. In order to relieve such problem, the proposed types of the configurations are the distributed type of PCS scheme and the hierarchical PCS scheme. In the distributed scheme, each PCS has its own LR and in the hierarchical PCS scheme, several LR are grouped to from a layer so that overall structure is a tree style.
