Volte reviews. VoLTE technology is a new word in cellular communication. VoLTE is what

Faced a problem - poor quality of communication, due to the fact that the reception is poor in the premises. Sometimes not at all.

Found a description Wi-Fi technologies Calling or Mobile VoIP or VoWi-Fi and as one of the branches of VoLTE development.

As providers say, the advantage of this technology is the implementation of a seamless transition between Wi-Fi and mobile networks during a conversation (the conversation will not be interrupted).

Megaphone launched August 2015
MTS launched ?
Beeline launched August 2015

Demonstration of VoLTE in the Beeline network from Mikhail Slobodin on September 14, 2015:

But more clearly about these technologies from LG

In Beeline, the SIP phone service is provided as part of the "cloud PBX" and only for corporate clients, Megafon within the Multifon framework for both private and corporate.

VoLTE is officially supported by Beeline only for devices:

Galaxy Alpha (SM-G850F)
Note Edge (SM-N915F)
Galaxy S6 (SM-G920F) - B7, B20
Galaxy S6 Edge (SM-G925F) - B7, B20

  • Huawei

Honor 6 (H60-L04)

Ascend Mate 7 (MT7-L09)

VoLTE working conditions in Russia are as follows:

  1. A SIM card with an ISIM or USIM program is required (SIM, USIM, ISIM are not cards, these are programs). You can get a SIM card from the operator.
  2. The processor on the phone must support this technology. For example, LG Nexus 5x has Snapdragon 808 (LTE Cat6) supports this technology.
  3. In OS mobile phone this technology must be enabled (as a rule, at the request of the provider, the manufacturer turns on this option in his phone and releases the firmware - more on that below) + then call the contact center and ask you to enable this service for you (in Beeline this service is called "enabling technical capability»SOC or VoLTE)

here is an example update for Alcatel OneTouch Idol 3 5.5 (6045Y) from Beeline:

4. An access point (APN) has been created with special parameters (these settings must be provided by the operator) and enabled Link aggregation(Carrier Aggregation). More details about Qualcomm modems can be found

Here is what the Beeline support service writes about this:

Login and password, you must be given by the operator!

here is another answer from the support team, but the information is contradictory (but in any case, a unique username, password, SIP URI is needed):

Dear Client, good day and good mood to you and your loved ones!

The VoLTE product can only be used with Softphone. You download the Softphone application yourself, the Company does not provide it.

The set with this tariff plan provides instructions for setting up "Softphone" and a unique login, password and SIP URI.

To establish a connection via VoLTE service, it is necessary that the “Softphone” application be activated for the Subscriber making and receiving a call. If a Subscriber makes a call to a Subscriber whose Softphone application is closed (inactive), then he hears an answering machine about the Subscriber's unavailability in the network.

But the most interesting thing is how to set up VoLTE in Beeline on a Nexus 5x (LGH791) device - I haven't found it yet. There are other Nexus 5x phone models available. But, in Russia, only the LG-H791 model is relevant (LTE Cat6 700/800/850/900/1700/1800/1900/2100/2600 (Bands 1,2,3,4,5, 7 ,8,9,17,18,19,20 , 26,28), TD-LTE 2300/2500/2600 (Bands 38,40,41)).

In theory, everything should look like this:

  1. Will launch Phone app (Dialer) on your phone and dial *#*#4636#*#*.
  2. Select Phone information.
  3. Next enable the flag Turn ON VoLTE Provisioned Flag... (I can't do it)
  4. Reboot telephone.
  5. Open Customization »More» Cellular networks and enable Enhanced 4G LTE Mode and then everything will turn on

UPD: For VOLTE to work, you need to make the operator's config of the device's modem and slip it into the device. In it, you must enable the mode Read IMS ISIM SETTINGS... You can do this yourself through QXDM for Qualcomm devices, or find the operator's config for the device in the form (mcfg_sw.mbn) Follow the link VOLTE config for Beeline.

This is an elf file, you need to decompile it, get xml from it (make changes), and then compile it under ARMv8

Digital technologies evolve relentlessly portable gadgets are constantly being improved, and their capabilities are immeasurably increasing, which allows you to comfortably use smartphones and tablets without any difficulties. However, many consumers want high-speed wireless connection in cellular networks. For this, not so long ago, such a communication standard as LTE was introduced to the Russian market. A large number of global manufacturers have begun to actively produce their own devices with additional option LTE, thereby expanding specifications devices.

If you want to commit phone calls in and other city networks, then you have to connect to 3G in order to establish a voice connection. Alternative option The solution to a common problem is 4g volte technology, which is gradually gaining popularity among numerous consumers.

VoLTE is a cutting edge technology based on the transmission of voice over LTE networks. The name is interpreted as Voice over LTE, and the most accurate translation is “voice over LTE”. Now you will have a great opportunity to make your usual phone calls, but at the same time, there is no need to switch communication technologies. Now the developers are actively developing their brainchild and improving it so that the technology will bring a lot of benefits to absolutely all owners of various gadgets. Some popular operators have already implemented VoLTE in Russia, due to which voice communication has become better and has numerous advantages, which we will discuss below.

Distinctive advantages

VoLTE technology is becoming more and more popular every day due to its advantages. If you are not yet using this option for its intended purpose or have not had time to purchase a smartphone with support of this standard connection, then we recommend that you familiarize yourself with the list of advantages of the above solution. Scroll positive sides consist of the following items:

  1. voice quality has improved markedly - the main disadvantage of second and third generation networks is the limitation of the audio data transfer rate, whose indicator usually does not exceed 16 Kbps, this is not enough to be considered high-quality voice transmission; therefore, VoLTE was created to add volume to any voice by reducing noise;
  2. simultaneous voice and data transmission - 3G and GSM are not capable of transmitting data at the moment when you call someone; if a call comes from another subscriber, then the working Internet connection is instantly "frozen" until the end telephone conversation; due to the considered option, the usual restrictions and load on the network can be avoided, leaving the quality of communication at a high level;
  3. increased capacity of cellular networks - the total number of subscribers simultaneously communicating with a certain base station, no longer limited, but on the contrary, increased by 3 times;
  4. the connection speed does not decrease and always remains high - when a call is made, a dial-up connection is established by switching the device to 3G and GSM, which leads to a 20-second delay; VoLTE does not provide for the use of a switching connection, so you will be very surprised when you find out how high the connection speed is;
  5. do free calls - voice is transmitted through a special packet data transmission system; when a phone call is made, only Internet traffic is spent; this means that the subscriber will be provided with free calls, but provided that he has an unlimited Internet connection and the selected telecom operator supports VoLTE.

Main disadvantages

VoLTE protocol is not perfect, as it may seem at first glance, because it has minor drawbacks that you should be aware of in advance before connecting. First of all, I would like to note the increased load on the smartphone. For this reason, not all manufacturers add this option to the characteristics of their devices. In order to reduce the expected load, it is necessary to perform additional work on the implementation of the protocol at the chipset level, and this requires impressive efforts and costs.

In most cases, VoLTE is found in products Apple, flagship models from Samsung, for example, also did not stand aside. If you want to purchase a smartphone with the presented technology from Chinese manufacturers, then before buying you need to clarify this issue so as not to be disappointed later.

Today, not all telecom operators are connected to VoLTE - it is too significant disadvantage, because high quality communication is achieved only when this condition is met. It is hoped that this technology will function optimally if all operators decide to implement it, but so far this has not happened.

VoLTE and telecom operators

Megafon has already implemented new service called "Call 4G", which provides HD voice over VoLTE or 4G networks. Thus, multitasking is ensured, data transmission during a telephone conversation does not stop. This means that during a call, the owner of the smartphone can surf the Internet and search for necessary information on third-party websites. At the moment, Megafon and Beeline provide access to this free service only to residents of Moscow and the Moscow region, but in the future it is planned to expand the number of cities involved.

Another well-known operator, MTS, intends to add a similar VoLTE option in 2018. This year, it is planned to conduct large-scale testing in various regions to determine the performance of the entire idea in practice. Based on the test results, a final decision will be made regarding any possible improvements.

The operator "Tele2" also did not stand aside and became interested in VoLTE. The company's management claims that initially this protocol will be available for two branded LTE and Tele2 Midi LTE. These devices will attract the attention of many consumers because they belong to the budget segment due to their low cost, which reaches 5 thousand rubles. But, so far, the technology under consideration is available exclusively for Muscovites.

Hopefully, you now understand how volte works and what it is in a phone. The presented protocol is really irreplaceable, because it allows you to perform several actions at the same time. Before connecting, you need to purchase mobile device that supports the corresponding communication standard, as well as familiarize yourself with the tariff scale of operators who have already added this option for their customers.

Looking through the list of characteristics of the smartphone, you can stumble upon the mention of VoLTE. With conventional LTE, everything is clear - this is a type of wireless communication that allows you to receive and transmit data at high speeds. And VoLTE - what is it in a phone? In short, this is a technology that allows you to transfer not only traffic, but also voice over 4G networks. But let's touch on this topic in a little more detail.

Initially Cell Phones were intended only for making calls, even the ability to exchange SMS messages did not appear immediately. Cellular networks the first generation actually transmitted only voice, most often even in unencrypted form. Only with the onset of the 2G era did different data transmission standards appear, including the familiar to many GPRS. But the priority in those days continued to be given to voice communication, the Internet connection was still used by very few owners of mobile phones.

Now the situation has changed dramatically. Each new standard cellular communication sharpened for an ever increasing data transfer rate. It got to the point that the fourth generation (LTE) is completely sharpened only for the transmission of Internet traffic. Voice calls are still made via 2G or 3G, there are no other options. Not until recently.

The main advantages of VoLTE

Now almost all major cities have LTE networks. In theory, a smartphone could work only in them, without wasting energy for switching between different communication standards. However, outgoing or incoming call forces the system to use the 3G connection. Each such synchronization consumes a certain amount of charge. VoLTE technology solves this problem. This function, roughly speaking, consists in the transmission of voice in digital form using 4G networks for this. With the support of this technology, voice calls will no longer force the device to connect to networks of previous generations. And in the future, this (purely theoretically) will allow telecom operators to abandon support for 2G and 3G equipment. But for this you need to wait for the moment when the population will have no old mobile phones left that do not have LTE support and, most importantly, VoLTE.

In fact, the new technology has other advantages as well:

  • Fast connection. If the phone does not waste time on the transition to 2G or 3G, then the call is made much faster. Sometimes the gain in speed reaches 30 seconds.
  • Calls may become free. In fact, a VoLTE conversation only consumes Internet traffic. If connected unlimited Internet, then the outgoing call will not spend a single extra ruble. You can talk even day and night.
  • Improving the quality of the voice. Whatever high quality microphone was not endowed with a smartphone, everything spoils the 3G connection. This communication standard simply cannot deliver perfect sound. And VoLTE is limited only by the stability of the signal reception. If the device supports the HD Voice codec, then the voice will become three-dimensional, and extraneous noise will disappear.
  • Increasing the capacity of cellular networks. A limited number of subscribers can connect to each 3G base. If the limit is exhausted, the device connects to a more distant base, and the connection deteriorates. LTE equipment has three times the capacity of 3G and six times that of 2G.
  • Simultaneous transmission of voice and traffic. When there is a conversation on the phone, none of the applications can receive data from the global web. Receiving traffic will resume only after the subscriber hangs up. The VoLTE technology has solved this problem - messages in messengers will continue to flow even during a call.

Modern smartphones with VoLTE

Support for the new type of communication is available in many devices, even in relatively inexpensive ones. For example, the corresponding technology is built into the Xiaomi Redmi 4X. This smartphone is among the most. People love the low price tag and optimal performance.

Of course, many are endowed with VoLTE support. In theory, the Samsung Galaxy S8 and Mi6 allow to talk via LTE networks. In less expensive devices, VoLTE is also found - for example, Meizu M5 Note and iPhone SE are endowed with the corresponding technology.

Russian operators

If smartphone manufacturers already support voice over LTE with might and main, then this cannot be said about telecom operators. In Russia, it is still more profitable to use equipment that works with networks of previous generations, reserving 4G only for Internet traffic. Progress is being made in this area, but very slow. Here's how things are with different Russian operators:

  • "Megaphone" launched VoLTE, but only in Moscow. Moreover, this function was initially allowed to be activated only by owners of smartphones and Apple. At the time of this writing, the list of devices has expanded to almost 40 models, including synchronization with VoLTE available on, ZTE V8, Vertex Saturn and LG G6.
  • MTS only tests new technology... Press releases have repeatedly stated that commercial exploitation VoLTE will be launched in 2018. Assumed to be available the new kind communications will be not only in Moscow.
  • Beeline gave its Moscow subscribers the opportunity to try VoLTE back in 2015. But testing was quickly completed, and since then there has been no news from VimpelCom. They say that owners using Beeline services will soon be able to speak on VoLTE, but these are just rumors.
  • Tele2 launched a new type of communication in April 2017, but only in Moscow. The list of supported smartphones is strictly limited. Moreover, you can feel the "super-quality" of the voice only when talking within the network.

Disable VoLTE

Some people prefer to disable all modules that are not being used for some reason. VoLTE deactivation does not make sense, because this function does not consume additional amounts of energy. Against, this technology will save battery power if the operator suddenly starts to maintain it.

However, it is very easy to disable VoLTE. To do this, follow the path: "Settings -> Connections -> Mobile networks-> VoLTE Calls "... All that remains here is to deactivate the corresponding switch. Please note that the path may differ on some smartphones.

Conclusion

When choosing a smartphone, you should not seriously pay attention to the VoLTE function, since Russian operators so far have only limited support for the technology. The only exceptions are residents of Moscow - they are the easiest to use the new type of communication. However, technologies are developing, operators are gradually purchasing new equipment. It is possible that one day support for VoLTE technology will appear in your city. Therefore, the function will definitely not be superfluous.

Mobile operators are constantly improving signal transmission technologies. Thanks to this, Megafon has developed a new VoLTE service. The option is intended for transmission sound signal on a 4G network. The function can only be used by subscribers with certain phone models.

The service is provided free of charge. Funds are debited according to the rates of the connected tariff plan. The option is available only to subscribers living in Moscow. To obtain detailed information, it is recommended to contact the operator.

Subscribers using Voice over LTE technology can make calls within the 4G network. Thanks to this, clients receive:

  • Connection quality;
  • The speed of the connection with the interlocutor;
  • The ability to use the Internet while talking.

For using the option, subscription fee not charged. Funds are debited as for a regular call. The cost is affected by the connected tariff plan.

Option works on ruler tariff plans"Switch on!":

  • Speak;
  • Write;
  • Look;
  • Listen;
  • Communicate.

Clients cannot use this option if they have previously activated the AntiAON package, Personal dial tone or One-time AntiAON package. There are no other restrictions on option compatibility.

The VOLTE technology was introduced by Megafon at the end of 2016, so at the moment the function is available on brand phones:

  • iPhone;
  • Samsung;
  • Sony Xperia;

As for Android smartphones, models released for Russian market. The lineup constantly updated. Therefore, you need to check with the operator whether the service is suitable for this or that phone.

It is important to note that some SIM cards are not 4G capable. To check whether it is possible to connect the number to high-speed technology, you need to dial the USSD command "* 507 #".

While using the service, no traffic is consumed. Voice transmission is carried out through a free internet channel.

How to enable the function

The option does not require connection. Subscribers only need to correctly configure their mobile devices:

  • Samsung: Go to settings and then open the "Connections" tab. At the next step, select "Mobile networks" and "Vo-LTE calls";
  • iPhone: Open the device settings configuration. Select "Data Options" and "Enable LTE Network". Activate Voice and Data;
  • LG: Launch configurator (gear icon), then select "Networks". In the menu that opens, go to "Additional" and "Mobile networks". To complete the configuration, you need to click on the "VOLTE" item;
  • Sony Xperia: In the settings, select "More", and then click on "Mobile networks". In the window that opens, activate "Enable LTE".

It should be noted that in latest models phones, setting LTE networks happens in automatic mode... If there is no "VOLTE" button in the settings, you need to change the firmware.

Subscribers who travel outside Moscow must turn off the function. Otherwise, you won't be able to make a call from your phone.

How to disable

It is not possible to deactivate the service. It can only be temporarily disabled. To do this, you need to change the settings of your phone. Everything is done in the same way as when the function is turned on.

It should be borne in mind that at the moment smartphones cannot disconnect themselves from 4G to 3G signal. Therefore, when you are in roaming, it is recommended to disconnect from the LTE network.

For whom is it suitable

The service is suitable only for Megafon customers who live in Moscow. In this case, subscribers must use an iPhone, Samsung or LG. The advantage of this option is the quality of the connection. During a call, users can view photos or use the navigator. The signal will be stable. If there is a need to use video communication, it is recommended to connect the "Videoconferencing" package. To get comprehensive information, you need to contact the operator.
