초록정보

New wireless systems have to support more users, offer more bandwidth and support more hard guarantees on maximum data transfer delay time. As the capacity of one cell is limited, cell size is reduced in busy area to support these requirements. As the cell becomes smaller, handoff occurs more frequently. Thus efficient handoff is needed to maintain call connections. In this paper, we analyze handoff for two kinds of new cellular communication architecture, called a ‘virtual cellular network(VCN)’: one is a‘distributed resource-control system’(DRS) and the other is a ‘centralized resource-control system’(CRS). A VCN can take advantage of the fact that the same data is received by multiple base stations. The DRS is a system in which every BS controls its own channels while the CRS is a system in which central station controls all channels. The analysis and simulation results show that both new call drop rate and handoff refused rate of the CRS are much less than those of the DRS.
