What is a 'handover' in mobile communication?

• A. The process of starting a new call
• B. Transferring an active call from one base station to another
• C. Connecting to a different network
• D. Ending a call abruptly

Answer: (B)

A 'handover' in mobile communication specifically refers to the process of transferring an active call or ongoing data session from one base station to another while the user is in motion. This mechanism is crucial for maintaining service continuity as a user moves through different coverage areas. As a user travels, their mobile device communicates with various base stations, and when the signal from the current base station weakens, the mobile network needs to seamlessly transfer the connection to a stronger signal from a neighboring base station. This process ensures that the call or data session continues without interruption, which is essential for mobile services, especially during calls or real-time data streaming. The other options fail to capture this specific functionality of handovers. Starting a new call, connecting to a different network, or ending a call abruptly do not involve the seamless transition of services that occurs during a handover. Each of those options describes different aspects of mobile communication, but they do not reflect the critical process of maintaining an existing connection while the user moves.
