ESTIMATING SIGNALING TRAFFIC IN MOBILE NETWORKS

A method upgrading a core section of a packet switched mobile network, includes: a) collecting information about a maximum signaling transaction amount managed by nodes of the core section with respect to active data connection established between user equipment and the packet switched mobile network, and calculating a corresponding active users parameter based on the collected information; b) retrieving an indication of how the maximum signaling transaction amount managed by the nodes is distributed among user equipment attached to the packet switched mobile network, and calculating a corresponding activity parameter based on the retrieved indication; c) calculating a forecasted number of user equipment which potentially can attach to the network in a future predetermined period; d) calculating a signaling traffic estimation based on the active users parameter, the activity parameter, and the forecasted number of user equipment, e) setting up the core section based on the calculated signaling traffic estimation.
