Techniques for determining data requirements for cellular phone use within one or more cells of a cellular network. A central processing repository receives user information identifying a cellular phone user within a cell of the network. In response, the central processing repository accesses usage profile information. The usage profile information specifies historical data usage in the cell for a given location and time. The central processing repository determines, based on the usage profile information, a current mode of operation and a probability that the current mode of operation will change. The central processing repository provides the current mode of operation and probability of mode change to a cell tower of the cell.
