Abstract
A handover method for a cellular radiotelephone networks in which, a call having been set up with a mobile via a first transceiver of a first cell, the handover consists in handing over to a second transceiver of a second cell and in switching in the mobile from the first transceiver to the second transceiver. The switching instruction interrupts the call in a defined cut-off time interval. The instruction to hand over the call is given under conditions such that the interruption of the call which may result from the handover operation occurs during the defined cut-off time interval.
