Claim Text:
1. A method for performing a handover of a mobile device from a source cell to a target cell in a cellular wireless telecommunication network, the method comprising: configuring the mobile device to transmit a first handover trigger signal to the source cell, when a difference between a signal strength of the target cell and a signal strength of the source cell as measured by the mobile device is above a first threshold; determining traffic load in the source cell; in response to the cell traffic load in the source cell being above a cell traffic load threshold, in addition to the configuration regarding the first handover signal and the first threshold, configuring the mobile device to transmit a second handover trigger signal to the source cell, in response to a difference between a signal strength of the target cell and a signal strength of the source cell as measured by the mobile device being above a second threshold, wherein the first threshold is larger than the second threshold; storing information about the mobile device that the handover has been performed from the source cell to the target cell after reception of the second handover trigger signal, in response to the handover being performed from the source cell to the target cell after reception of the second handover trigger signal, thereby recording an indication that the handover from the source cell to the target cell has occurred; and making a further handover of the mobile device from the target cell back to the source cell less likely based on the recorded indication.
