Abstract
The invention relates to improvements in standby time in a dual mode mobile communication device. A device according to the invention comprising means for repeatedly monitoring and determining signal quality of signals received on a first network, whilst the signal quality remains above a predetermined first threshold, means for also monitoring and determining signal quality of signals received on a second network at selected intervals if the determined signal quality in the first network falls below the first threshold and for switching-communication to the second network in dependence on the relative qualities of the two signals, and means for also monitoring and determining signal quality of signals received on the second network more frequently if the signal quality on the first network falls beneath a second lower threshold, and means for switching communication to the second network in dependence on the relative qualities of the two signals.
