Since its inception, mobile phones have experienced the first generation of analog mobile phones (1g), the second generation of GSM, TDMA and other digital mobile phones (2G), the second generation of mobile communication technology CDMA and the third generation of mobile communication technology 3G.

The end of the era of mobile communication industry

At the recent ran#88 plenary meeting, 3GPP announced that the ran6 working group responsible for GERAN and UTRAN wireless and protocol work was officially closed. The ran6 working group, which has just been declared closed, has been responsible for studying 2G and 3G wireless functions and defining specifications and interfaces related to GSM / edge wireless access network (GERAN) and UMTS wireless access network (UTRAN). That means the exit of 2G / 3G.

2G / 3G off network trend

With the continuous development and evolution of the new generation of mobile communication technology, mobile communication technology should have choices, and these appropriate practices should also be selected. As the saying goes, the survival of the fittest is good. With the maturity of 4G technology and the development of 5g technology, few people will use 2G and 3G networks. On the one hand, operators do not want to operate multiple networks. If 2 / 3 / 4 / 5G is operated at the same time, it will cause great pressure and high maintenance cost. Unimportant networks are closed, which can save costs, and in addition to re cultivating the released spectrum, spectrum resources are also very valuable. Of course, many people worry that in some remote areas, there are only 2G and 3G signals, but no 4G signals are available.

There is no doubt that this is a problem that operators must solve this year. If 2G and 3G are turned off, please ensure signal coverage and smooth user transition and upgrade to 4G. 2G / 3G frequency clearing and de networking will make it pay more attention to the construction of more valuable 5g network. On October 22, 2019, Wen Ku, director of the information and Communication Development Department of the Ministry of industry and information technology, made it clear that the withdrawal of 2G and 3G is the inevitable choice for the upgrading of mobile communication, and it is also the main practice of various countries in the world. At present, the conditions for 2G and 3G withdrawal of China’s mobile communication networks have gradually matured.

Frequency clearing and de networking is not sudden

As 3GPP said, the closure of ran6 working group marks the end of an era in the mobile communication industry. As a leader in the information and communication industry and an advantageous manufacturer in the 5g field, Huawei obviously has a deep insight into this. In an exclusive interview during the first world 5g conference, Huawei’s wireless product line, as a leader in the information and communication industry and an advantageous manufacturer in the 5g field, obviously has a deep insight into this. In an exclusive interview during the first world 5g conference, Cao Ming, vice president of Huawei’s wireless product line, shared with c114 the company’s thoughts and thoughts, especially put forward suggestions on “2G / 3G frequency reduction and network retirement and 4G / 5G collaborative development” for the network challenges faced in the early stage of 5g development.

In the process of frequency reduction and de networking, it also faces many challenges:

1: The first is the cost problem. If the original 2G and 3G users are moved to the 4 / 5G new network, the cost of replacing mobile terminals and tariff packages will increase. How to solve the problem in terms of cost tests the wisdom of operators.

2: The second is the use of mobile phones for the elderly, because many elderly people can’t use smart phones and it’s very difficult to operate. How to develop smart phones suitable for the elderly is also a challenge that 2 / 3G has to face.

3: Finally, the problem of user experience before frequency and network removal is completely cleared. Not all 4 / 5G can cover the whole country. For example, in some remote areas, the signal is bad, and what impact will 2 / 3G network removal have on them? Therefore, network removal needs to be carried out step by step and in different regions. As vice president Cao Ming said above, ‘2G / 3G frequency reduction and network cancellation, 4G / 5G coordinated development’.
