Discuss the concepts of “Location Update” (LU) and “Handover” (HO) in telco networks?
Location Update (LU) and Handover (HO) are two crucial concepts in telecommunications that play a significant role in ensuring uninterrupted connectivity. Let’s delve into each of them and understand their importance in cellular networks.
Location Update:
When you power on your mobile device or move to a new cell “in ideal mode” , Location Update comes into play. It involves informing the network about your current location, allowing it to accurately route incoming calls and messages. By updating your location information, the network ensures seamless communication by delivering them to the right cell and ultimately to your device. Stay connected wherever you go!
For Location Update:
🔹 Your mobile device initiates the process by sending a signaling message to the network.
🔹 The network acknowledges the request and updates its database with your new location information.
🔹 This enables the network to route incoming calls and messages correctly, connecting you with the world.
Handover:
As you move from one area to another “in connected mode” , Handover takes charge to maintain a continuous and seamless connection. When your mobile device transitions from one base station to another, Handover facilitates the transfer of your ongoing call or data session. It ensures that you experience uninterrupted communication without call drops or data interruptions.
For Handover:
🔹 When you move to a new cell, the network evaluates factors like signal strength and quality to determine if a handover is necessary.
🔹 If required, the network selects the appropriate target cell and instructs your device to switch to it.
🔹 Your device seamlessly disconnects from the current cell and connects to the target cell, ensuring a smooth transition of your ongoing communication.
Both Location Update and Handover play vital roles in maintaining connectivity:
🔸 Location Update keeps the network informed about your location, enabling efficient call and message routing.
🔸 Handover ensures uninterrupted communication during your mobility, allowing you to stay connected without disruptions.
Whether you’re stationary or on the move, these mechanisms work together to create a seamless communication experience in cellular networks.
