Operators recently started blowing 5g again? Browsing the news a few days ago, it was found that China Mobile recently launched a new product that claims to create a "new vision of calls", and China Telecom and China Unicom also announced not long ago that the two sides will realize the interconnection of 5g calls. According to them, this is a new generation technology based on 5g network, which can make video calls directly through dial-up**
Not only is it better than voice and video functions on various social software, but it will not be interrupted when other calls come in. The most convenient thing is that doesn't need to download the app**
So the question is, what is this "5g vonr"? Why do operators have so much confidence and dare to blow like this?
In fact, we can call this new product: 5g vonr HD call technology**
In short, when people call, it can not only make calls clearer and delay lower , but also have clearer voice and video image quality than in the 4G era**
Most importantly, making a call under Novr technology will not affect 5g data transmission, let alone via 4G network**
Huh? If we really want to solve this problem, we'll do a new 5g package right now.
Because calling can lead to cell phone The degradation of network signal has been in my impression for a long time.
Even in the early years of indirect calls, the mobile phone would directly disconnect the network and could not open the web page at all. And even in the 5g era, this problem has not been completely solved.
Some bad friends should have noticed: when there is no WiFi, 5g network is used very well. At this time, when you suddenly answer the phone, you will find that... The network speed sometimes "pops" and is gone.
This has also led to some small partners not buying 5g accounts to a certain extent. It's very annoying to use it anyway. Originally, downloading a game in the background should be solved soon. As a result, I answered the phone and found that the progress bar basically didn't change much.
We clearly spent 5g
But in my opinion, this pot really can't be carried by 5g network. Because this is actually a problem of technical iteration, in the early mobile phones, surfing the Internet and making phone calls are two different things**
When mobile phones first appeared, the main purpose of operators was to successfully "call".
At that time, people didn't even know what streaming media and mobile social networking were. Naturally, they didn't think so much.
Therefore, the operators at that time used a resource consuming and inefficient technology: CS circuit switching**
In short, when we make a call, we will establish a completely "point-to-point" call line. This line will seize the bandwidth originally used for data traffic, and can return to the normal network state only after the call is over.
It's like a street with traffic control. No one can cross this road except specific people (you and the person you're talking to). Even before the end of the control, you can only walk on this road.
I think some poor friends must remember that when they called, if the other party was on the phone, you could only hear the busy tone of "Dudu"
Later, with the advent of the 3G era, not only QQ, microblog and other mobile social platforms began to emerge, but also the mobile network speed was faster. But the technology of voice call has not improved.
That is, at this time, people found that when using 3G mobile phone card to make a call, the mobile phone signal will be directly reduced to 2G. The most intuitive experience is: the network will be disconnected when you call**
Fortunately, the 3G network speed itself was not fast... And we were still used to calling and sending text messages as the main contact method at that time, which didn't arouse people's special disgust.
Unexpectedly, it was later developed to 4G, and the network speed was directly increased by N times. Wechat and QQ platforms also gradually began to replace SMS and telephone.
So the problem comes, because 4G itself does not support CS circuit switching scheme, that is, it cannot realize voice call.
But making a phone call is at least the basic function of the mobile phone. We can't just leave it alone. So at that time, the operators handed over the Internet service to 4G, and the old technology of 2 / 3G was still used to make calls.
At this time, it's a little uncomfortable to disconnect the network. After all, when a call falls directly from 4G to 2G, the gap is really a little too big.
And this is not a good thing for operators, because the maintenance of old technology is troublesome and the efficiency is poor... People have to arrange and promote 4G, which will have to be solved sooner or later.
Therefore, the mobile communication industry learned from the pain and finally developed a new scheme called "4G volte" It can package the data of the telephone as a whole, and transmit it directly through the network like the data of watching movies on the Internet, without establishing a separate voice channel
People only need to connect their mobile phones to the 4G network and can surf the Internet while making calls. Moreover, due to the progress of 4G network technology, the quality of voice calls has also ushered in an unprecedented improvement.
It's strange that 5g is developing too fast. The new communication technology scheme has been used for less than two years, and the 5g network call signal is degraded again
I see. Anyway, the technical iteration of voice service must be half a step behind the network transmission.
In the first two years, it may be to put 5g into use as soon as possible. Operators mainly prefer 4G and 5g shared resources (NSA independent Networking) to deploy networks.
At that time, the coverage of 5g dedicated network scheme (SA independent Networking) was not high and not stable enough.
If in areas with poor signal, the mobile phone will repeatedly jump between 4G and 5g networks. If you make a call through 5g network at this time, you may find that you can't hear clearly, delay or even disconnect directly.
In order to maintain the quality of voice calls and improve the user experience of making calls, operators have to move out the old method and iterate again, which is called "EPS fallback" voice service transition scheme.
In this technology, the Internet service is handed over to 5g, and 4G volte is responsible for making phone calls. It's just that from now on, making phone calls and surfing the Internet on mobile phones are the same thing... As long as one network speed is degraded, the other will have to be reduced.
Let's say that 4G volte itself is innovative and easy to use, which leaves some face for 5g mobile phones.
Now 5g vonr is actually equivalent to "returning 5g to 5g", so you don't have to borrow the east wind of someone else's 4G younger brother.
In essence, the difference between 5g vonr and 4G volte is not great It is not so much an iteration of voice technology as to create better conditions for the application of 5g.
On the other hand, 5g vonr is bound to drive major manufacturers in the mobile phone industry to launch new actions**
Because some models in the first batch of "5g launch" and some phones with insufficient configuration do not support 5g vonr. For example, Qualcomm products must at least have models above Xiaolong 865 .
Huawei is a mobile phone loaded with Kirin 5g series chips , as well as MediaTek Tianji series chips or mobile phones with X60 independent baseband will not be affected.
Even if the hardware of the mobile phone meets the requirements, it also needs to update the software... In short, if you want to sell the mobile phone, either OTA or press conference, you have to choose the same.
Fortunately, the Kirin chip has been ready early, otherwise it will be a wave of worse
However, in my opinion, although the emergence of 5g vonr can bring a better experience, if the poor friends' mobile phones are unqualified, there is no need to replace them in a hurry**
Just like the 5g new call of this mobile, its main function is direct video call function** You say it's useful. It can also be used in 4G before. It's really not good. There's wechat
At present, the benefits that ordinary consumers can feel are that the network bandwidth is larger, the voice coding technology is more advanced, and the effect of data transmission is better.
Or is it that it used to take 3 or 4 seconds to dial to hear the ring across from you, but now it only takes 1-2 seconds?
But we really can't say it's useless.
Just from the current function, I don't think it's enough to support everyone to contribute their wallets immediately. Unless in the future, it can derive more interesting and useful things about body feeling, interaction, remote sharing and so on.
This wave, apart from the fact that operators can promote the replacement of 5g packages at a faster speed, I think the biggest benefit to ordinary people at present is:
The money spent on our 5g package can be a serious "5g fee".
