The present invention provides for a method of transferring operation of a mobile radio communication device from a first network to a second network, while connected to the said first network, and including the steps of identifying cells of the said second network, comparing signal power level of the identified cells with a threshold level and connecting to a cell of the second network identified as having a signal power level above the said threshold level such that transfer from, for example, a 3G network to a 2G network can be achieved without requiring the 3G network to monitor the 2G network prior to such handover. Preferably, connection is to the first cell identified as having a signal power level above the threshold and the threshold may be set by way of network messaging of the first network. |
