Abstract
A mobile communication device measures a received signal strength indicator, RSSI, from a base station. An adjusted signal strength indicator, RSSI-ADJ, is calculated for the base station as a function of both the RSSI and a traffic indicator received from the base station. A determination is made, based on the calculated RSSI-ADJ, whether the mobile communication device should roam.
