Abstract
A method for data transmission, contemplates calculating a cell-load ratio by:where rcl,n-1 is a cell-load ratio calculated in a previous stage, rcl,n is an instant cell-load ratio, α is a forgetting factor, dn is an instantaneous cell load, and Sn is a frame capacity; and broadcasting the calculated cell-load ratio by carrying the cell-load ratio in a designated message.Methods of a cell selection and a handover for a subscriber which are initiated by a subscriber are in dependence upon both of the cell-load ratio and the signal strength provided by the base stations.
