AN ENHANCED SOLUTION FOR HANDOVER

摘要

Method in a wireless device for managing handover from a source cell to a target cell. When a first difference of a first quality measurement of a signal from the target cell minus a first quality measurement of a signal from the source cell is above a first threshold for a first time period, the wireless device sends a report to the source network node and receives a message to handover to the target cell. When a second difference of a second quality measurement of a signal from the target cell minus a second quality measurement of a signal from the source cell is above a second threshold value, for a second time period, the wireless device triggers handover to the target cell. When it is not above the second threshold value, for the second time period, it cancels the handover.

1. A method in a wireless device for managing handover from a source cell to a target cell, the source cell being serviced by a source network node, and the wireless device, the source network node, the source cell, and the target cell being comprised in a wireless communications network, the method comprising:
when a first difference of a first quality measurement of a downlink, DL, signal from the target cell minus a first quality measurement of a DL signal from the source cell is above a first threshold value for a first time period, sending a measurement report to the source network node, wherein the measurement report indicates the first difference, receiving a message from the source network node to handover to the target cell, when a second difference of a second quality measurement of a DL signal from the target cell minus a second quality measurement of a DL signal from the source cell is above a second threshold value, for a second time period, triggering the handover to the target cell, and when the second difference of the second quality measurement of the DL signal from the target cell minus the second quality measurement of the DL signal from the source cell is not above the second threshold value, for the second time period, cancelling the handover from the source cell to the target cell.
