What is a Handover (HO)?
Welcome to the “DEFINITIONS” category of our page! In this post, we’ll dive into the details of a handover (HO) and explain what it is.
Have you ever wondered how a mobile device can seamlessly switch between different base stations or access points while maintaining a continuous connection? Well, the answer lies in the process called a handover (HO), also known as a handoff.
Key Takeaways:
- A handover (HO) is the process of transferring an ongoing call or data session from one cellular base station or access point to another.
- It allows mobile devices to maintain a continuous connection while moving between different coverage areas.
When your phone or any other mobile device moves out of the coverage range of one base station or access point, a handover process is triggered to transfer the ongoing call or data session to another station or access point with stronger signal strength or better coverage. This ensures uninterrupted communication and a smooth user experience.
The handover process involves several steps to ensure a seamless transition:
- Signal Measurement: The mobile device continuously measures the signal strength of neighboring base stations or access points.
- Handover Decision: Based on the signal measurements, the device selects the best candidate for the handover. Factors like signal strength, load balancing, and available resources are taken into consideration.
- Handover Execution: The mobile device initiates a request to perform the handover to the selected base station or access point.
- Handover Completion: Once the new station or access point acknowledges the handover request, the ongoing call or data session is transferred, and the connection is maintained.
Handovers can occur within the same cellular network or between different networks, depending on the technology in use. Some common handover types include:
- Intra-frequency Handover: Occurs between base stations or access points operating on the same frequency.
- Inter-frequency Handover: Takes place between base stations or access points operating on different frequencies within the same network.
- Inter-system Handover: Involves transferring the connection between different cellular technologies, such as from 4G to 3G or vice versa.
By allowing mobile devices to seamlessly move between different base stations or access points, handover processes ensure reliable and uninterrupted communication, even when you’re on the go. So the next time you make a call while walking down the street, remember that a handover is taking place behind the scenes to keep you connected!
