Carriers have recently started blowing 5G again? A few days ago, Tony found that China Mobile recently launched a new product that claims to create a "new vision of calling", and Telecom and China Unicom also recently announced that the two sides will achieve 5G call interconnection.
According to them, this is a new generation of technology based on 5G networks, mainly through dial-up for video calls.
Not only is it better than the voice and video features on various social software, but it will not be interrupted when other phone calls come in, and the most convenient thing is that there is no need to download the app. So the question is, what exactly is this "5G VoNR"? Why do operators have so much confidence to blow like this?
In fact, this new product, we can call it: 5G VoNR HD call technology. Simply put, when people are on the phone, it not only makes the call clearer and less delayed, but also has a clearer voice and video quality than in the 4G era. Most importantly, voNR technology will not affect the transmission of 5G data, let alone through the 4G network.
Well? If you can solve this problem, Tony will immediately go to the new 5G package. Because the phone call will lead to the downgrading of the mobile phone network signal, I have been in my mind for a long time.
Even in the early years of indirect telephone calls, the mobile phone would be directly disconnected from the Internet, and the web page could not be opened at all. And even in the 5G era, this problem has not been completely solved. Some poor friends should pay attention to: when there is no Wifi, the 5G network is used very well, and then suddenly take a phone call to find... Internet speed sometimes "snaps" a little, gone. This has also led to some small partners not to buy 5G accounts to a certain extent, and it is quite annoying to use anyway. Originally, the background download of a game should be resolved quickly, but I answered a phone call and found that the progress bar had not changed much.
We obviously spent 5G money... But in Tony's view, this pot really can't make the 5G network back. Because this is actually a problem of technical iteration, early mobile phones, Internet access and telephone calls can be said to be two different things. When mobile phones first appeared, the main purpose of operators was to be able to successfully "call".
At that time, people didn't even know what streaming and mobile social networking were, and naturally they didn't think about it so much. So the operators at the time used a more resource-intensive and inefficient technology: CS circuit switching.
Simply put, when we call, we build a completely "peer-to-peer" line. This line will preempt the bandwidth originally used for data traffic, and can only return to the normal network state after the call is over. Like a traffic-controlled street, no one can cross the road except for a specific person (you and the person you're talking to). Even before the end of the control, you can only walk on this road. I think there are bad friends who must remember that in those days of calling, if the other party is on the phone you can only hear the busy tone of "beep beep"...
Later, the 3G era came, not only the mobile social platforms such as QQ and Weibo began to emerge, but the mobile phone network speed was also faster. But the technology of voice calls has not improved much.
It was also at this time that people found that when calling with a 3G mobile phone card, the mobile phone signal would be directly reduced to 2G. The most intuitive experience is that the phone will be disconnected. Fortunately, the speed of 3G itself was not much faster... And everyone was still used to using phone calls and texting as the main contact methods, so as not to cause people to be particularly disgusted.
Unexpectedly, it later developed to 4G, the network speed directly increased by N times, and the platforms such as WeChat and QQ gradually began to replace SMS and telephone.
The problem arises, because 4G itself does not support the CS circuit switching scheme, that is, it cannot implement voice calls. But calling is the basic function of the mobile phone, and it can't just be left alone. So at that time, operators handed over the Internet service to 4G, and the phone call still used 2/3G of the old technology.
At this time, the call disconnection is a bit uncomfortable, after all, a call directly fell from 4G to 2G, this gap is really a bit too big. And this is not a good thing for operators, because the old technology is troublesome to maintain, and the efficiency is poor... People still have to lay out and promote 4G, and sooner or later this matter will have to be solved. So the mobile communications industry finally developed a new solution called "4G VoLTE". It can package the data of the phone as a whole, and the data of watching movies on the Internet is transmitted directly through the network, without having to establish a voice channel separately.
People only need to connect their phones to a 4G network to be able to make calls and surf the Internet at the same time. And thanks to the advancement of 4G network technology, the quality of voice calls has also ushered in an unprecedented improvement. Blame the 5G development is too fast, the new communication technology program has been used for less than two years, and the 5G network call signal downgrade has come again... Tony can see clearly that the technical iteration of voice services will always lag half a step behind network transmission. In the first two years, it may be that in order to get 5G into operation as soon as possible, operators mainly prefer 4G and 5G resources (NSA non-standalone networking) solutions to deploy networks.
At that time, the coverage of the 5G dedicated network solution (SA standalone networking) was not high or stable enough. If the signal is not good in the area, the phone will repeatedly jump between the 4G and 5G networks. If you make a call over a 5G network at this time, you may find that you can't hear clearly, delay or even disconnect directly from the line halfway through the conversation. In order to maintain the quality of voice calls and improve the user experience of phone calls, operators have to move out the old method and iterate, called:"EPS Fallback" voice service transition plan.
In this technology, the Internet service is handed over to 5G, and the phone calls are handled by 4G VoLTE. It's just that from this time on, phone calls and mobile phone Internet access are already the same thing... As long as one network speed is downgraded, the other has to follow. For Tony, thanks to the 4G VoLTE itself, it is innovative and easy to use, so that the 5G mobile phone call to save some face.
Now 5G's VoNR is actually equivalent to "bringing 5G back to 5G", no longer need to borrow the east wind of other people's 4G brothers. Essentially, the difference between 5G's VoNR and 4G VoLTE isn't very different. It's not so much an iteration of voice technology as it is about creating better conditions for 5G to be used. From another aspect, 5G VoNR will inevitably drive the major manufacturers in the mobile phone circle to launch new actions. Because some of the earliest "5G debuts", and some mobile phones with insufficient configuration, do not support 5G VoNR. For example, Qualcomm products must at least have Snapdragon 865 or more models. Huawei is a mobile phone loaded with Kirin 5G series chips, as well as MediaTek Tianji series chips or mobile phones with x60 independent basebands will not be affected.
Even if the hardware of the phone itself meets the conditions, it still needs to update the software... In short, if you want to make the phone sell, either OTA or conference, you always have to choose the same. Fortunately, the Kirin chip was already prepared early, otherwise it would be another wave to make it worse... However, in Tony's view, although the emergence of 5G VoNR can bring a better experience, if the mobile phones of poor friends do not meet the requirements, there is no need to rush to replace. Just like this mobile 5G new call, it mainly features direct video calls. You say it's useful, you can also use it when it was 4G before, it really can't work and WeChat...
For now, the benefits that ordinary consumers can feel are nothing more than 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 opposite ringtone, and now it only takes 1-2 seconds? But we really can't say it's useless. Just from the current function, Tony felt that it was not enough to support everyone to contribute their wallets immediately. Unless in the future, it can be based on this to derive more fun and useful things about somatosensory, interaction, remote sharing, etc.
In addition to the fact that operators can use faster speeds to promote everyone to replace 5G packages, I think the biggest benefit for ordinary people at present is that the money spent on our 5G packages can be the "5G fees" of the eight classics.
