What is the definition of a "handoff" in mobile communications?

In mobile communications, a "handoff" refers specifically to the process of maintaining service continuity during a call as a mobile user moves from one cell coverage area to another. This is essential for ensuring that ongoing calls do not drop when moving between different base stations or network cells. During a handoff, the mobile network will transfer the call from one cell tower to another seamlessly, allowing the user to continue their conversation without interruption.

This definition underscores the importance of network management systems that monitor the signal strength and quality, initiating the handoff process to another cell before the current connection becomes too weak. Options that hint at physical movement, data transfer, or starting new calls do not capture the crucial aspect of maintaining an existing connection, which is the essence of a handoff in mobile communications.
