Recently, 5G (fifth generation mobile communication technology) standard set usher in a key node. The United States on December 2, 3GPP (standardization body of mobile communications) news, 3GPP 5G NSA (Non-Standalone, non-independent networking) standard was officially frozen. According to 3GPP's plan, the 5G standard is divided into two types: NSA and Standalone (Standalone). Among them, 5G NSA networking requires the use of 4G base stations and 4G core networks, with 4G as the anchor point of the control plane to meet the needs of aggressive operators to utilize existing LTE network resources to achieve rapid deployment of 5G NRs.

        A communications expert on surging news reporters said NSA as a transitional program, mainly to enhance the hot regional bandwidth as the main goal, there is no independent signaling plane, relying on 4G base stations and core network work, the relative standard-setting progress faster. At the same time, NSA's 5G performance and capability will be greatly reduced. In addition, to realize 5G NSA, it is necessary to upgrade the existing 4G network, which has an impact on the performance and smooth running of the existing network, and needs operator attention.

       According to 3GPP's plan, in June 2018, six months later, the SA independent networking solution will be released. It is a 5G target solution accepted by the industry and can achieve all the new features of 5G and is conducive to playing the full capabilities of 5G. However, NSA standard freezing is equally crucial. The communications expert said that the completion of the 5G standard NSA program is an important milestone in the 5G standardization process, marking a 5G standard and industrial processes into a substantial acceleration phase, 5G business into the countdown.

        However, he also emphasized that the 3GPP group conference in early December just announced that the 5G NSA passed the discussion, but the specific technical details and specifications will be fully completed and disclosed at the 3GPP plenary session on December 22, and now the details planning It is too early to discuss. Standard freezing is of great significance to the communications industry. Even if some core standards are set down, even some fine-tuning of formal standards in the future will not affect the product development of previous vendors.

Huawei, ZTE to promote 5G pre-commercial worldwide

        Yang Chaobin, President of Huawei Wireless Products, recently said in a media interview that Huawei is promoting 5G pre-commercial operations all over the world. "China is mainly Beijing, Shanghai and South Korea mainly Seoul and Seoul's lively Gangnam district. Italy chose Milan and Japan chose Tokyo, Canada mainly with Dell in Vancouver and Toronto, the UK mainly with BT in London, Germany in Germany and Deutsche Telekom in the second half of this year to start the construction of 5G pre-commercial trial network. "

        Yang Chaobin said that the main purpose of pre-commercial system is to verify the key technologies, the key technology inside the standard has now been identified, but the key technology in the actual network which can be how it must have the appropriate network to fully verify that these technologies can really achieve What kind of result.

        It is understood that in September of this year Deutsche Telekom officially released in Berlin, Germany, the first pre-commercial system, which uses Huawei's pre-commercial system 5G, which contains the bearer, access network and CPE. Yang Chaobin said Huawei next year will launch a full set of 5G network equipment business system, "This means that we will make this commitment and customers, he would like to buy a device I can sell to him. And this device is to support the future, is to support Smooth evolution toward the future, a set of equipment in the network will exist for more than 10 years, not a standard version of the equipment will be replaced.

        In addition to Huawei, ZTE, another Chinese telecom equipment provider, is also implementing 5G pre-commercial services worldwide. In November of this year, ZTE and Japan's Softbank jointly conducted a 5G substantive experiment in the 4.5 GHz band at Chi Gate in Minato-ku, Tokyo. In October, ZTE announced a joint venture with Wind Tre, Italy's largest mobile operator, and Italy's leading cable operator Open Fiber, building the first 5G pre-commercial network in Europe on the 3.6-3.8GHz band. Guoxin Securities recently announced that Huawei and ZTE two telecom equipment providers in the low-band 5G technology far ahead of Ericsson and Nokia, the latter two companies mainly concentrated in the high-frequency band put more energy.

China Telecom opened 5G pilot stations in six cities

5G mobile phone to wait for 2019 years

        Prior to the mobile communication is mainly to solve the communication before the people, the future era of 5G Internet of Things era, only one part of the communication, even a small part. 3GPP listed 5G era three typical scenarios are mobile broadband, large-scale machine communications, high reliability and low latency communications.

        3GPP standard specifications to Release as a version of management, an average of one to two years to complete a version of the development. The R15 version of the main contents of the NSA and SA standards, which is the consumer mobile communication problems; large-scale machine communication (Internet of Things), high reliability and low latency communication (unmanned applications, etc.) two scenarios will be R16 Version development, R16 version will be completed in 2019. By 2020, 5G will be commercially available worldwide.
