Abstract:
A handover control method is disclosed for a wireless communication device connected to a serving network node which provides a serving cell. The method comprises establishing a handover control configuration, shared by the WCD and the SNWN, comprising a neighboring cell measurement triggering criterion, a handover triggering criterion, and transmission resource parameters for measurement signals of a neighboring cell. The method also comprises performing channel quality measurements of the serving cell and detecting fulfillment of the neighboring cell measurement triggering criterion based on the channel quality measurements of the serving cell. The method also comprises performing channel quality measurements of the neighboring cell and detecting fulfillment of the handover triggering criterion based on the channel quality measurements of the neighboring cell.
