A method and a mobile device configured, when in idle mode, to select a target frequency from a network in response to a redistribution information from the network, including starting an evaluation timer; performing measurements on a first set of frequencies throughout a duration of the evaluation timer; selecting the target frequency based on the measurements of the first set of frequencies; and starting a second timer, which is distinct from the evaluation timer, during which time the device performs measurements on a second set of frequencies comprising the target frequency.
