What does volet call mean?

Volet call refers to a high-definition voice call made on the 4G network. It is the first high-quality audio and video call service based on the 4G network launched by China Mobile. It can realize dual services of making calls and surfing the Internet at the same time. One of the big advantages of VoLTE is that call quality is better than 3G or 2G connections because much more data can be transmitted over 4G than 2G 3G; this makes it easier to understand what the person on the other end of the phone is saying. There is no need to switch to 3G when using VoLTE calls, which means users can continue to use 4G to use other functions on the phone while making calls.

The operating environment of this tutorial: HarmonyOS 2 system, HONOR V30 mobile phone.

volet call means HD voice call on 4G network. Volet is an IP data transmission technology that can unify data and voice services on the 4G network. In other words, when users are using VoLTE, VoLTE mobile phones can still maintain smooth operation on the 4G network.

VOLTE (VoiceoverLTE) is the abbreviation of 4G high-definition voice, that is, high-definition calling. It is a high-quality audio and video call service based on the 4G network first launched by China Mobile, which can realize dual services of making calls and surfing the Internet at the same time.

What is VOLTE?

VOLTE stands for Voice over Long-Term Evolution, which means a high-speed wireless communication standard for mobile phones and data terminals. It is based on the IP Multimedia Subsystem (IMS) network and uses specially tailored profiles (defined by the GSM Association in PRD IR.92) for the control plane (Control plane) and the media plane (Media plane) of voice services on LTE. Enable voice services (control and media levels) to be transmitted as data streams in the LTE data bearer network, without the need to maintain and rely on traditional circuit-switched voice networks. The voice and data capacity of VoLTE is more than three times that of 3G UMTS and more than six times that of 2G GSM. Because VoLTE packet headers are smaller than unoptimized VoIP/LTE, it also uses bandwidth more efficiently.

After activating VoLTE, there is no need to return to the 2/3G network from 4G to make a phone call. When making a call, it often takes 5-6 seconds or even longer for non-Volte. However, activating VoLTE only requires two calls. The call is now connected. The call quality is clearer and more natural, and then VoLTE calls introduce high-definition voice and video encoding, and the voice quality is significantly improved.

Data and calls are carried out at the same time. After activating this function, another advantage is that users can also switch out during the call. Even if you are playing a mobile game and a call comes in, it will not Cause network disconnection. In addition to high-definition voice, VoLTE also supports high-definition video calls and can be switched back and forth during the call, which is quite powerful and practical.

What are the benefits of VoLTE?

• Exceptional call quality

One of the great advantages of VoLTE is that the call quality is better than a 3G or 2G connection because over 4G Much more data is transferred than 2G or 3G. This makes it easier to understand what the person on the other end of the phone is saying. Essentially, it's an HD voice call and the overall experience is much richer.

• Improved coverage and connectivity

VoLTE connects calls twice as fast as when using 2G or 3G, and works without a 4G signal 2G and 3G connections are still available, which just means overall mobile coverage is greater, because without VoLTE you won't be able to make or receive calls in places where there is a 4G signal but not 2G or 3G.

This rarely happens, but some of the frequencies that 4G operates on (such as the 800MHz spectrum) have much greater coverage than the 2G or 3G spectrum, so we will be able to get the signal far away from the mast or in other In buildings where signals are difficult to penetrate.

• Better Battery Life

Smartphone users will also find that VoLTE extends their battery life because without it, whenever you When making or receiving calls, our phones have to switch from 4G to 2G or 3G because 4G calls are not supported, and once the call ends, our phones switch back again. All this switching, plus the need to search for a different signal each time, takes a significant toll on the battery.

• Faster Data

Since we don’t have to switch to 3G when using VoLTE for calls, this means you can continue while you’re on the call too Use 4G to use other features on your phone. This is very convenient if you are multi-tasking. For example, while browsing the web or downloading an app.

• Works with Wi-Fi

4G Calling also provides the ability to move seamlessly between that and Wi-Fi Calling, without interrupting the call, so if you leave one signal type, you can continue using another.

• Video Call

Theoretically it is also possible to make a video call over 4G, just like a Skype call, except you just use your mobile number and Ability to use the regular dialer and calling interface so you can make and receive video VoLTE calls from anyone else, rather than relying on a separate account.
