The hotline to support medical declaration 18001119 is completely free. On 4-6, after investigation and verification, the Department of Telecommunications, Ministry of Information and Communications said that the information about subscribers being deducted when listening to a call displaying the word “BCD Covid19” in Bac Ninh is complete. totally fabricated. In order to provide maximum support for Bac Ninh in the prevention and control of Covid 19, from the morning of May 29, the Ministry of Information and Communications has directed telecommunications businesses to use Callbot technology to call mobile subscribers in the province. Bac Ninh and Bac Giang have not installed Bluezone to mobilize and guide people to install and use this application to protect themselves and the community against the Covid-19 epidemic. In particular, under the direction of the Ministry of Information and Communications, these calls are completely free of charge when people answer the phone or call back. However, recently, in Bac Ninh province and on social networks, information sharing about the situation has been spread: the number of the switchboard impersonated based on the Covid-19 epidemic to cheat money withdrawals from customers’ and customers’ phones. people. Mobile phone subscribers are charged when receiving an incoming call displaying the words “BCD Covid19” or “BCD Covid-313158” or “18001119”. In order to have a basis for information and propaganda on the mass media to let the people know, as well as to serve well the prevention and control of the Covid-19 epidemic in Bac Ninh, Bac Giang and other provinces and cities in the area. nationwide, Department of Telecommunications, Ministry of Information and Communications have investigated and verified. Accordingly, subscriber information that is deducted when listening to the phone is completely fabricated, people need to be alert when sharing, to avoid affecting the prevention and control of Covid-19 epidemic in Bac Ninh province. A facebook post corrected the previous false information. Source: Mic.gov.vn. In addition, the information that subscribers lost their charges when they heard from the Covid-19 switchboard spread on social networks has made people in Bac Ninh province bewildered, not daring to listen to the phone, greatly affecting the public sector. disease prevention and control as well as the security and order situation in Bac Ninh province. Therefore, the Department of Information and Communications of Bac Ninh province is also coordinating with relevant agencies to verify and track down the subjects who posted and shared articles about listening to calls losing money to handle according to regulations. provisions of the law. People installing and using Bluezone will help them receive timely warnings and support from health authorities when they come into contact with an infected case.

2G network will be “wiped out” by Korea Previously, in July last year, SK Telecom officially stopped providing 2G network service, while another Korean mobile operator, KT Telecom, stopped providing 2G network service since 2012. due to the rapid development of advanced mobile network generations and the significant decrease in the number of 2G network users. 2G mobile service started operating in Korea in 1996 based on the world’s first commercial code-shared multiple access network built by SK Telecom. The number of 2G subscribers nationwide surpassed 20 million in 2006 but began to decline after the country commercialized 3G and 4G networks in 2003 and 2011, respectively. It is known that by the end of March 2021, the number of 5G mobile network subscribers in Korea has reached 14.48 million, accounting for 20% of the total 71.1 million mobile subscribers, according to data from the Ministry of Information Technology. trust this country.

Vietnam is one of the fastest growing telecommunications markets in the region and the world in recent years. According to the General Statistics Office, at the end of 2005, Vietnam had only 15.8 million telephone subscribers, including 8.7 million mobile phone subscribers and 7.1 million landline phone subscribers and 210,000 telephone subscribers. cover the Internet. But only 5 years later, the whole country had 125.9 million phone subscribers, nearly 8 times more. In which, there are 111.5 million mobile phone subscribers, 12.8 times higher and 14.4 million landline phone subscribers, 2 times higher. The number of Internet subscribers increased rapidly during this period with 3.7 million fixed broadband Internet subscribers, 17 times higher than 2005. But after that, the number of phone subscribers decreased gradually, the biggest decrease was fixed phones. In the period 2012 – 2015, the number of telephone subscribers achieved an average growth of 0.5%/year, of which the number of mobile phone subscribers increased by 2.1%/year and fixed subscribers decreased by 17.7%/year. year. In contrast, the number of fixed broadband Internet subscribers is still growing quite high, an average of nearly 16% per year, reaching 7.7 million subscribers in 2015. However, in recent years, the telecommunications market is facing saturation of traditional telecommunications services. The number of landline phone subscribers tends to decrease sharply. By the end of 2020, there were only 3.2 million subscribers, down 41% compared to the same period in 2015 and down 78% compared to the same period in 2010. The operation of the fixed telephone service segment is currently only in moderation, mainly serving agencies, government organizations and businesses. For mobile phone subscribers, by the end of 2020, the whole country has 123.6 million subscribers, which is only close to the number of subscribers in 2015. In addition to the recent decrease in demand, there are also mobile phone operators. The network handles garbage SIM according to the regulations of the Ministry of Information and Communications. The number of broadband Internet subscribers continued to maintain a high growth rate for many years when at the end of last year, there were 16.7 million subscribers, 2.2 times higher than in 2015, an average annual increase of 16.9%. The growth rate of the telecommunications market is also reflected in the revenue figures, whereby telecommunications revenue in 2010 reached 177.8 trillion VND, maintaining the growth rate of over 40% in previous years. By the period 2011 – 2015, post and telecommunications revenue continued to maintain a fairly high growth rate, increasing by nearly 60% in 2015 compared to 2010, increasing by nearly 10% on average per year. In the period of 2016 – 2018, telecommunications revenue maintained a fairly high increase of nearly 8% compared to the previous year, but by 2019 only increased by 2.6%. Particularly in 2020 due to the impact of the Covid-19 epidemic, telecommunications revenue dropped sharply by 13.6%, reaching only VND 315,200 billion. The telecommunications market share is quite fiercely competitive by optimizing value-added services on the number of existing subscribers. In addition, revenue from traditional telecommunications services is also greatly influenced by the popularity of free calling and messaging OTT applications. Decision No. 749/QD-TTg dated June 3, 2020 of the Prime Minister approving the “National Digital Transformation Program to 2025, with orientation to 2030” has made Vietnam one of the The first country in the world to issue a program on National Digital Transformation, which is a favorable condition for businesses to actively exploit the opportunities brought by the technological revolution. With the goal of “Vietnam belongs to the group of 70 leading countries in e-Government (EGDI)”; “Digital economy accounts for 20% of GDP”; “The fiber optic broadband network infrastructure covers over 80% of households, 100% of communes” and “Universal 4G/5G mobile network services and smart phones”, telecommunications businesses, digital businesses there is a lot of room for growth.

Illustration. According to Hai Duong Police, recently, many mobile subscribers have received messages impersonating financial institutions and banks, sending fake and fraudulent content in order to appropriate people’s money. Through verification and evaluation, the authorities found that these fake messages did not come from the systems of financial institutions, banks and telecommunications businesses, but were distributed through transmitters. fake mobile signal. These are devices of foreign origin, which are illegally traded and used by objects for the purpose of carrying out attacks to spread spam messages to deceive users, especially users in remote areas. urban area. Fraudsters often use fake broadcast devices to send spam messages directly to the phone without going through the mobile telecommunications network. These messages are sent by objects that change source information in order to create trust and deceive users. The message content is often advertising, instructions or contains links to fake websites like official websites of financial institutions, banks to lure and steal users’ information such as accounts, password, OTP code. Many users do not recognize the fake website, so they provide personal information to access the bank account such as entering the account name and password. After the user provides the information, the fake website will redirect to another website or notify the user to wait. The subject uses the user’s personal information to log in to the official website of financial institutions and banks to get the OTP authentication code (if necessary).

In addition to a number of corporations such as Samsung Electronics, LG Electronics of South Korea and Huawei of China, most recently, Apple (the US technology corporation) also announced to recruit engineers to participate in research and development. to develop wireless technology next generation 5G. According to current research directions, the theoretical speed of 6G network will be one Tb / s, about 100 times higher than the theoretical speed of the 5G network (10 Gb / s). The new technology will also have broad coverage and be more energy efficient than the previous generation. Most importantly, 6G hopes to solve the limitations of current 5G networks. Specifically, even though it is considered as an Internet of Things (IoT) network, 5G still has a long way to go to achieve universal universality due to its limited ability to transmit signals at a height of many thousand meters. ground or deep below the ground or seabed. Meanwhile, 6G is research-oriented to meet both intelligent connectivity, deep connection, heterogeneous connection and everywhere. On the other hand, although 5G network has helped people make good use of artificial intelligence (AI) technology to optimize, distribute resources and process data, the forecast 6G network can do better by making AI becomes intelligent with the processing speed close to the human brain. 6G will integrate the new physical, digital, and services worlds to deliver stricter network performance metrics (KPIs) than 5G. However, the development of 6G networks is still just beginning and the end result will depend on speed of deployment and consensus on the technologies to deliver the ultimate standard. Experts say that the next 10 years will be a period for research and 6G will start to be commercialized from 2030. In the process of deploying previous generations of mobile networks such as 2G, 3G or 4G, Vietnam often lags behind the world. As for 5G networks, we are now starting to perform tests with the expectation of entering the first groups of countries to deploy the technology. But according to experts, in fact, Vietnam is still quite far away from the world in terms of research capacity and deployment methods in the telecommunications sector. Therefore, even though all countries have the same opportunity in terms of time to lead the research and deployment of 6G networks, not all countries have enough potential in science, technology as well as finance. join the race for core technology of 6G right now. Instead of racing to research core technologies, we should take advantage of other existing strengths to catch this wave, such as: Focusing on research and production of terminals for 6G; researching in-depth in the control and optimization of the 6G network system; research on AI technology for management system, data processing in 6G network system; blockchain security research (blockchain) … to solve the safety problem in the new network system. This may be a medium and viable market for Vietnam in the future.
