Answer:
Handoff
Explanation:
Handoff sometimes referred to as handover is the process of transferring a call that is active or a data session from a cell in a cellular network to another cell in a cellular network. It occurs when the base station signal is changed as the cell is shifted and does not result to any form interaction in the data session or active call.
A data session user or active caller would experience no interruption in service when the handoff is well implemented.
