For an efficient software download in cellular CDMA systems, location dependant session admission control (LDSAC) is presented. In the LDSAC scheme, a mobile that is located near cell center can request software download session, but the mobile that is located far from cell center can request session only after approaching near the cell center. Performance is analyzed in terms of handoff rate, mean channel holding time, session blocking probability and handoff forced termination probability. Numerical results show handoff rate between cells in the proposed scheme is reduced to 30-250% compared to conventional scheme, according to traffic characteristics such as terminal speed, session duration time and the size of the allowable zone area in a cell for the initiation of the session. And new session blocking probability decreases slightly, but handoff session forced termination probability decreases drastically.
