What is VoLTE?
VoLTE, short for Voice over LTE, is a technology that enables voice calls over 4G LTE networks. In simpler terms, it allows users to make voice calls using the same LTE network that provides high-speed data connectivity. This means that VoLTE calls are carried over the same network that you use to browse the internet, stream videos, and access various online services.
Unlike traditional voice calls that rely on 2G or 3G networks, VoLTE uses the IP Multimedia Subsystem (IMS) to facilitate voice communication over LTE networks. This results in significant improvements in call quality, speed, and reliability.
How does VoLTE work?
To understand how VoLTE works, let’s take a look at the underlying technology. When a user initiates a VoLTE call, the following process occurs:
- The device sends a request to the LTE network to establish a voice call.
- The LTE network allocates a dedicated bearer for the voice call, which is a dedicated channel for voice traffic.
- The device then sets up an IP connection with the IMS core network, which is responsible for managing and routing voice calls.
- The IMS core network establishes a connection with the called party’s device, and the voice call is connected.
- Throughout the call, the voice data is packetized and transmitted over the LTE network, using the dedicated bearer allocated earlier.
Benefits of VoLTE
So, what makes VoLTE so special? Here are some benefits that set it apart from traditional voice calling technologies:
- Improved call quality: VoLTE calls offer superior voice quality compared to traditional voice calls, thanks to the high-definition audio capabilities of LTE networks.
