Method for performing a handover of a mobile device

A base station apparatus comprising:

• a processor configured to
• configure an associated mobile device to transmit a first handover trigger signal to a source cell being served by the base station apparatus, when a difference between a signal strength of an associated target cell and a signal strength of the source cell as measured by the mobile device is above a first threshold;
• receive the first handover trigger signal from the mobile device;
• determine a cell traffic load in the source cell;
• in response to the cell traffic in the source cell being above a cell traffic threshold, in addition to the configuration regarding the first handover signal and the first threshold, configure 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;
• receive the second handover trigger signal from the mobile device;
• and,
• store 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 the case that the handover has been 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
• make a further handover of the mobile device from the target cell back to the source cell less likely based on the recorded indication.

A non-transient computer-readable storage medium comprising instructions that when executed by a base station apparatus cause the base station apparatus to perform the following:

• configuring an associated mobile device to transmit a first handover trigger signal to a source cell served by the base station, when a difference between a signal strength of an associated target cell and a signal strength of the source cell as measured by the mobile device is above a first threshold;
• determining a cell traffic load in the source cell;
• in response to the cell traffic load in the source cell being above a cell traffic threshold, in addition to the configuration regarding the first handover and 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;
• and,
• 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.
