Abstract
A method of triggering a network handover controlled by a communications device in a communications system comprising a plurality of networks with which the communications device can perform a handover operation to, the method comprising the steps of: determining a signal characteristic of each available candidate network in said communications system; forecasting a future value of said signal characteristic; determining a future handover margin for said signal characteristic of the network connection established by said communications device; determining if another available candidate network signal characteristic exceeds said handover margin at a future time, and if so, performing a handover operation to said other available candidate network, wherein said future handover margin for said signal characteristic is varied dynamically in dependence on said forecasted signal characteristic.
