The changes are initiated and controlled by MQPBR client module in cooperation with the ITHC module.
The results of these measurements are a direct input to the ITHC module for handover decisions between tunnels.
This module on the user side is represented as ITHC software module and has a direct interaction with other software modules of the virtual network layer.
At this stage of the process all the above components are in direct interaction with the ITHC. The second phase of the process presents an analysis of the input parameters through an intelligent algorithm in step 6, with aim to decide on handover.
