"Pake stop", which was regarded as a problem by expanding the use of 5G, and the efforts of each mobile company for solutions (Mynavi News) --Yahoo! News

From the new SoftBank service presentation on September 14, 2021.Combined with the rapid expansion of 5G terminal sales and the development of the area maintenance, there have been many voices pointing out "stoppage stops" on SNS.

In 2021, the use of 5G was advanced and became a problem. This is an event that a 5G antenna is standing but cannot communicate, but why does a package stop? As a solution, what kind of efforts do mobile companies are working on? → See here for the past episode. [Image] From a briefing session about 5G held by NTT DOCOMO on December 13, 2021. It is said that the company is using 4G when the quality of 5G is poor at the start of communication, and it is said that "Pake stop" will occur in December 2021 and in December. It was a year when 5G expanded rapidly this year. In fact, the development of a 5G base station of the three major mobile phones progresses rapidly in 2021, and in 2020 the area that was a "point" became "face", and the 5G compatible smartphone is not only a high -end model but also a middle. It is clear that 5G has rapidly familiar, as it has rapidly expanded to a class and a low -end model in the 20,000 yen range. The reason why a package stops is that one of the causes is the current 5G, a non -stand -off (NSA) that adds a 5G base station in a 4G core network and a base station. It must be the operation of. And the other is that 5g area maintenance is on the way. In NSA operation, 4G communication is based, so the terminal is connected to a 4G base station first, and if there is a 5G base station nearby, it will be connected to that high -speed communication. However, if the radio waves arrived from the 5g base station are weak, communication will not be possible and a condition of a package will occur. At the beginning of the 5G service, the network of each mobile company seems to have been designed to connect to 5G with the highest priority to make use of 5G high -speed communication as much as possible. However, 5G uses a higher frequency band than before, so in many cases the user communicates on the boundary of the area when the surface cover is not progressing due to the maintenance of the area, which leads to the frequent occurrence of packaging. That's why. Moreover, as mentioned earlier, the smartphone released in 2021 was 5G compatible with a very large number of terminals, including low and medium -priced ones, so most of the people who replaced them with the latest model are 5G. It will be used. The rapid increase in the number of users who can use 5G while the area maintenance is in good condition seems to be a major factor in the problem of stopping the package. Due to the improvement of the area, the problem of solutions in tuning is a phenomenon that is likely to occur only because the area maintenance of 5G is improved, so the area is expanded to achieve a 4G population coverage, and users on the 5G area boundary line. It is thought that the solution will progress if reduced. However, 5G often uses a higher frequency band than before, so it takes time to maintain the area. Therefore, it is network tuning that mobile companies are currently focusing as a countermeasure against packaging. As mentioned earlier, giving priority to 5g base stations in NSA environment is a major factor in the occurrence of package, so the priority of 5G is reduced and the radio wave environment is severe. By tuning to connect to 4G, it is less likely to stop the package. In fact, the three mobile phones, which are promoting the 5G area expansion, have been focusing on tuning to prevent packaging since late 2021. For example, NTT DOCOMO, which held a briefing on 5G on December 13, 2021, not only uses 4G radio waves when the 5G radio wave quality is poor at the start of communication, but also 4G radio waves during 5G communication. It is said that multiple tuning has been applied to prevent packaging, such as making it easier to flow data and optimizing the width of the frequency band assigned to the terminal to make it easier to reach the uprising communication speed. As a result, the company's traffic data has shown that the connection efficiency of 5G has improved by about 10%and the 5G data flow rate has increased by about 30%, which has shown that it has led to the resolution of the package. That said. In the future, communication quality improvement will be promoted by tuning to improve the efficiency of radio waves and to improve the communication speed. Of course, the essential solution of the package stop is to expand the 5G area in NSA environment and the transition to SA operation, so it will be difficult to completely eliminate the package stop. However, it is certain that improvements are being made due to a series of measures that each company tackle, so in 2022, it will be possible to communicate with 5G without choosing a place.
