Thanks to CTOnews.com netizens for the delivery of clues about the past and Weilai battery car. CTOnews.com, December 3 (Xinhua)-- the Ministry of Industry and Information Technology recently responded to netizens'"suggestions on ensuring the basic communication functions of old mobile phone users", thepaper.cn reported today.
The netizen mentioned in the message that the country has made great efforts to develop 5G communication technology, but a large number of people in our country are still using old mobile phones, button phones and other electronic devices, and some basic telecom operators have illegally shut down the base stations of 2G, 3G and 4G basic communication signals in the name of network upgrading, resulting in a large number of mobile phones of the aforementioned group customers unable to answer and make calls.
Therefore, the netizen hopes that the Ministry of Industry and Information Technology will make overall arrangements in the light of the actual situation of our country, ensure the basic communication functions of the aforementioned groups, develop new communication technologies step by step, and retain the normal operation of basic communication technologies.
The reply from the Ministry of Industry and Information Technology of Pixabay is as follows:
Since June 2019, our Ministry has issued a 5G license and 5G has been officially used for commercial use in China. China's mobile communication has entered the stage of "four generations in the same house" of 2G, 3G, 4G and 5G.
The withdrawal of 2G / 3G network is the inevitable choice for the upgrading of mobile communication network, and it is also the main practice in the world. According to incomplete statistics, more than 100 operators around the world have implemented 2G / 3G withdrawal, using the frequency of 2G / 3G retreat for 4G / 5G deployment.
Using the limited frequency resources and network resources to the development of 5G and 4G mobile communication networks will help to reduce the network operation cost as a whole and improve the network operation efficiency of our country.
At present, all Netcom mobile phones need to support all six standards and more than ten frequency bands. Withdrawal from the network can also reduce the complexity of mobile phones, help to improve the efficiency of mobile phones and reduce the terminal cost of mobile phones.
However, the Ministry of Industry and Information Technology also said that the withdrawal of mobile communications from the network is not simply "as soon as you withdraw." The Ministry of Industry and Information Technology said that it is necessary to improve user protection measures to fully protect the rights and interests of users in order to implement the withdrawal of the network.
Enterprises should plan and inform early that they must have user safeguard measures and perfect user follow-up plans, and have the ability to provide better network coverage, stronger business capabilities, and better service quality. to create conditions for users to be "willing to retreat" and "willing to retreat".
According to previous reports by CTOnews.com, in November 2021, the Ministry of Industry and Information Technology clearly put forward "speeding up the withdrawal of 2G and 3G networks and coordinating the coordinated development of 4G and 5G networks" in the "14th five-year Plan", and included 2G / 3G withdrawal as the key work of network infrastructure during the 14th five-year Plan period.
Among them, China Unicom has the fastest speed of 2G disconnection, which announced the orderly promotion of 2G frequency reduction in 2018, and achieved the full withdrawal of 2G by the end of 2021. At the same time, its 3G network withdrawal is also in progress.
China Telecom's 2G / 3G withdrawal was originally scheduled to be completed by the end of 2024, but it is also reported that it will be completed as early as the end of 2023. China Mobile clearly proposes to stop adding 2G users by the end of 2020, and will accept 2G users by NB-IoT and 4G Cat1/1bis technology.
"Guangdong Telecom responded to shutting down the 2G network: promoting the construction of the 5G network, and is currently carrying out network upgrading work throughout the province."
