3GPP did say goodbye to 2G and 3G, but this does not mean”quit the network”

By yqqlm yqqlm

As we all know, 2020 is”the year of 5G popularity”. In fact, this means that a large number of more powerful, more advanced, more mature, or lower-priced 5G mobile phones will be listed within this year; meanwhile, it also means that the construction of 5G networks will be expected to be initially urban in this year. The basic coverage is covered, and the construction and experimentation of further advanced technologies such as SA (Independent Networking) and millimeter wave are started.

In this process, there is a topic that has recently come The more often you see it in the newspaper-that is,”withdraw from the Internet”. Whether it is the various “internal notices” dug up by the three major operators, or the content of various experts and scholars on the construction of “give way” for 2G and 3G for 5G, almost every time it can attract the attention of a large number of ordinary consumers, and also let Many people worry over and over again whether the old mobile phone or feature phone being used can still be used normally.

No, just on July 13, 2020, an article about the official closure of the 3GPP RAN6 working group occupies many pages of technology media. In this article, the author once again puts forward the argument that the conditions for 2G/3G dropout are gradually maturing.

However, the problem is that the 3RAN closed”RAN6 What exactly is a”working group”, does it really mean that the 2G/3G withdrawal has already been fixed? In order to clarify the matter, we at Sanyi Life not only checked the relevant content of the 3GPP official website for this matter, but also learned in detail about the slightly special way of work of the 3GPP organization.

First of all, the full name of 3GPP is the 3rd Generation Partnership Project, also known as the”3rd Generation Partnership Project.” In essence, this is a technical standardization organization composed of telecom operators, telecom management departments, and some enterprises from all over the world. The original purpose of 3GPP was to discuss and solve the problem of”how to transition from 2G to 3G”, so it was called 3GPP.

So within 3GPP, organizations and institutions from various countries, And how do companies coordinate their work? Simply put, its organizational structure is completely oriented to technical issues. At the top is the Project Coordination Group (PCG), which has three technical specification groups (TSG), responsible for the radio access network (RAN), services and systems (SA), and core network and terminal equipment (CT) . Each technical specification group is divided into different specific working groups according to different topics, focusing on studying their specific technical content. For example, the”RAN6″ working group that was closed this time is the sixth working group under the jurisdiction of the Radio Access Network Technical Specification Group, whose work is to continue to study the radio technology of 2G and 3G standards.

Speaking of this, maybe some keen friends have discovered the problem Where it is. Yes, 3GPP closed the RAN6 working group, which means that this wireless communication standardization organization has decided not to continue to study 2G and 3G technologies. But at most, it can only be said that 2G and 3G technologies will no longer have new and improved technologies in the future. What is the direct relationship with the”withdrawal”?

Maybe the key to misunderstanding is the title of the official draft when 3GPP announced the shutdown of RAN6.

As you can see. 3GPP used”End of an era” to describe the RAN6 shutdown. If we just did not give you the reason for the establishment of the science popularization organization, then this title is indeed very easy to be misunderstood as it is a statement of 2G/3G should be withdrawn from the Internet. But if the combination of 3GPP was originally established during the period of 2G and 3G communication, the first research topic received was to understand the fact that the 2G network continues to improve, then the”end of the era” is obviously referring to the establishment of 3GPP. The initial task, has completely completed this matter.

When we carefully studied the 3GPP draft, we found that they spent more than half of their time on the RAN6 group, originally in 2G improvement and 3G globalization promotion Aspect history. This further illustrates that the”end of an era” in the title refers to the fact that 3GPP’s decades-long research work on 2G and 3G technology has come to an end, not the end of 2G and 3G technology itself.

Not only that, but at the end of this official draft 3GPP also has two quite intriguing statements. One is”We are fully aware that the GERAN and UTRAN standards and the core network behind them are completely stable and can be used as long as necessary (we are safe in the knowledge that the GERAN and UTRAN standards, and the core network behind them are completely stable and can continue to be used for as long as there is a need)”.

The other paragraph is the two announcements attached at the end of the article. The first is that although the RAN6 working group has been closed, the future TSG RAN working group will”take over.””, and continue to supervise matters related to 2G and 3G standards. The other is specifically to deny a title”RAN6 closure, GERAN no more (RAN6 closure, GERAN comes to an end)” that was used in this draft, pointing out that the GERAN specification (that is, 2G) will still be maintained .

So what does this mean? Presumably, we don’t need to explain more.
