Abstract
A direct retrying method in CDMA system based on the macro diversity is disclosed in the invention. The conditions for the direct retrying are determined; the number of the cells, which are previously requested for the admission, is read out; the cells are determined by using the cell information planned by the network as the auxiliary decision; the selected cells having the same coverage are re-divided to obtain different sets of the cells; one cell set is selected from the different cell sets as a target cell set of the direct retrying; and the resources are requested from all of the cells in the target cell set of the direct retrying. If the admission of one cell is successful, then the direct retrying will be successful. The said method can increase the success rate of the direct retrying, decrease the number of the times for switching after the mobile station entering the dedicated channel, and optimize the system performances. <IMAGE>
