discuss the concept of handover in cellular networks?
Tech Junction Answered question December 27, 2023
Telecommunications handover, also known as a handoff, is the seamless transfer of an ongoing communication session from one network cell or base station to another, ensuring uninterrupted connectivity and high-quality connections. It’s like passing the baton of communication smoothly as users move within the coverage area.
Let’s break down the key steps involved:
- Measurement: Mobile devices check neighboring cells or base stations, measuring signal strength and quality.
- Decision: Based on these measurements, the device or network infrastructure decides to initiate a handover, considering factors like signal strength, available resources, and network policies.
- Handover initiation: The mobile device requests a transfer to the target cell or base station.
- Authentication and authorization: The infrastructure verifies the device’s identity and permissions, it’s optional in operators.
- Channel setup: The target cell or base station assigns resources and sets up a communication channel.
- Data transfer: The ongoing communication session seamlessly switches to the new location.
- Handover completion: The network updates records and confirms the successful handover, ensuring uninterrupted connectivity.
Telecommunications handovers are crucial, especially in cellular networks and wireless communication systems, where mobility is essential. These mechanisms minimize disruptions, reduce dropped calls, and optimize network resources to provide a seamless user experience.
