Recently, a method to use replicated data on a server in order to get new data without missing any information has been studied on wireless telecommunication networks and satellite services. Static Replica Allocation (SRA) that traditional scheme has been used for the replication method on the server. This replicates the data on the replica server after a moving host has been transferred to another cell. In case the number of users is smaller than that of cells, the network of the SRA is an efficient scheme in the standpoint of access cost, and if there are few moving users, no trouble will happen. But if there are no moving users in a cell, the data will not be shared. This paper proposes new method of relocation, that is, USRA (User Select Replica Allocation) based on data consistency scheme (called USRAC) after replicating the data to the cells for the users, and also analyzes access cost according to the moving rate of mobile users, according to the access rate of mobile hosts, and according to the number of cells of mobile users and mobile hosts.
