Aspects and embodiments provide methods of handing over a communication link between a cell and user equipment in a wireless communication network from a source cell to a target cell. One method comprises: receiving a handover command message comprising an indication of a plurality of handover instances at which the user equipment is to attempt establishment of a communication link with the target cell; attempting establishment of a communication link with the target cell at a handover instance and monitoring for receipt of an indication that a communication link with the target cell has been established; and maintaining a communication link with the source cell through the plurality of handover instances, until the indication that the communication link with the target cell is established is received. Aspects further provide network nodes and computer program products configured to perform such methods. Aspects and embodiments may provide a method for enhanced handover. The methods described may reduce user plane interruption time and may re-use legacy procedure and signalling without need for use of a specific "handover activation timer". |
