The soft handover procedure comprises the following steps: 
  • ? Based on the Measurement Control information from the RNC, the UE measures the intra-frequency neighboring cells, and reports the measurement result to the RNC via Measurement Report. 
  • ? The RNC compares the reported measurement result with the set threshold to decide the cells to be added and deleted. 
  • ? (If some cells are to be added, the RNC notifies the Node B to get ready. )
  • ? The RNC notifies the UE to add and/or delete cells via the Active Set Update message. 
  • ? After the UE successfully update the active set, UE will send Active Set Update Complete to inform RNC.
  • ? (if the cells are deleted, the Node B will be notified to release the corresponding resources. )
  • ? After the soft handover, perhaps the measurement control information changes, if it is, RNC will send new Measurement Control to UE. 
*  The original communication is not affected during the soft handover procedure so that 
smooth handover from a cell to another can be successfully completed.
