In the telecommunications industry, a handover refers to the process of transferring an ongoing call or data session from one cell to another without interrupting the communication. This seamless transition is crucial for maintaining the quality of service for mobile users as they move between different network coverage areas.

Types of Handover

There are several types of handovers, including:

  • Intra-cell handover: This occurs when a mobile device moves within the coverage area of the same cell.
  • Inter-cell handover: This occurs when a mobile device moves from one cell to another within the same network.
  • Inter-system handover: This occurs when a mobile device moves between cells belonging to different wireless technologies, such as from 4G to 3G networks.

Challenges of Handover

Handover processes can be complex and challenging, as they involve coordinating communication between multiple base stations and ensuring the continuity of the call or data session. Factors such as signal strength, network congestion, and handover algorithms play a crucial role in determining the success of a handover.

By continuously optimizing handover procedures, network operators can provide a seamless and uninterrupted user experience for mobile subscribers, ensuring reliable connectivity and high-quality service.
