During this year's World Mobile Communications Conference (MWC 2017), the industry's dialogue on 5G will not only go back to 4G, but also quietly shift from 5G's "core network" to "new radio technology"...
In 2016, the World Mobile Communications Conference (MWC) was filled with commitments related to the 5G communications network, when vendors said that 5G and 4G would not be the same, opening up new business opportunities for telecom operators; with software like Elements such as Definition Network (SDN) and Network Function Virtualization (NFV) are introduced into the core network. They promise that telecom operators will be able to provide multiple forms of differentiated network services on the same infrastructure. The 5G vision depicted in 2016 by MWC Except exciting and shocking.
After one year, 4G is still a hot topic at the MWC site in 2017. Various technology suppliers have discussed how the industry can make full use of the LTE network in the next few years. At the same time, the 5G standard is also a hot topic of discussion, but The focus of the industry has quietly shifted from the original "core network" to "new radio."
The author noticed that this trend was due to the announcement of the "non-standalone 5G" program - just before the opening of MWC 2017, a group of telecom operators and technology vendors jointly published the plan.
In the name of "accelerating 5G", including Ericsson, Huawei, ZTE, Qualcomm, Intel, and network operators such as AT&T, Deutsche Telekom, KDDI, KT Corp., NTT Docomo, SK Telecom, Sprint and Vodafone, etc., announced that they will support "non-independent" 5G new radio technology (NR); this new proposal will be held in the recent 3GPP wireless access network plenary session (Radio Access Network) Plenary).
But to be honest, what is "non-independent" 5G? How is it different from 5G? What is something like the 4G enhanced version? More importantly, what impact does this additional standard have on the entire market moving towards 5G?
Matt Grob, Qualcomm's chief technology officer, explained in an exclusive interview with EE TImes that "non-independent 5G" is a 4G "set-up" mode based on 4G. By introducing an "intermediary" step, operators will be able to leverage existing LTE radios and develop packet core networks in a configuration called "non-independent 5G NR."
This allows operators to start trial operation and deploy 5G NR in 2019, without waiting until 2020; at the same time operators can also add new 5G radio access carriers to support 5G usage scenarios after 2019.
Perhaps the most striking part of the "non-independent 5G NR" is its ability to "consolidate" the timeline of the complete 5G standard, including the independent 5G NR of Release 15, especially in certain telecom operators such as Verizon and Korea Telecom. The 5G version goes beyond other competitors.
In short, the vendors that support non-independent 5G want to set the tone before the orchestral assembly is completed. I hope that 3GPP can complete the 5G NR specification as soon as possible to avoid a lot of pre-5G pre-standards. The above-mentioned vendors promoting the "non-independent 5G" plan said in a joint statement: "Based on the current 3GPP Release 15 schedule, 5G NR deployment based on standard 5G NR infrastructure and devices will not be completed until 2020 at the earliest. Will start."
While Qualcomm's technical director Grob praised Verizon as a "catalyst" to accelerate the 5G standard in an exclusive interview with EE TImes, he also worried: "There is a big question: Verizon will return to support after pursuing its own version of the 5G specification." (3GPP's 5G) industry standard?" The answer to this question is still unknown, and I don't know if the "non-independent 5G" will be able to recover the elves flying out of the bottle.
At the same time, during the MWC period, it was also proved that the mobile communication industry is not all unanimous and active non-independent 5G. Why? For example, Nokia is clearly not supporting the non-independent 5G camp, and the company has been evading this topic at MWC's press conference; but the company seems worried that accelerating the development of the NR standard may be related to achieving, for example, the network. The 5G packet core development of key functions such as network slicing is not synchronized.
At the MWC show, the same questioning voice pointed out that today's manufacturers who are eager to finalize the 5G NR specification are specifically focused on developing 5G usage scenarios based on existing 4G applications they know.
Every time the mobile communications industry embarks on the development of new radio standards, technology vendors and operators tend to be busy with political operations and to allow new standards to be ridiculously machine-speeded; it is foreseeable that the media will follow suit. We have seen the same replay of the same story again and again, as the cellular communication standard evolved from 2G to 3G and then from 3G to 4G; unlike the past, 5G is not just about faster development and greater bandwidth. New radio standard
Obviously, it is very important to stabilize the 5G NR specification as soon as possible, but what about other 5G core networks? Where have we progressed? Have we considered the new 5G usage scenarios that all 4G networks cannot provide? If this new issue is just that some companies want to lead other companies, why are they so eager to do so?
