"Samsung S9/S9+ has finally arrived on schedule", "Huawei released the world's first full-screen notebook", "vivo brings a true full-screen mobile phone"... Recently, the technology enthusiasts have a lot of talks after the meal. Highlights at the World Mobile Communications Conference. Let's take a look at the related content with the network communication Xiaobian.
For the 2018 Bar Show, which is more than half of the process, I believe everyone knows that its main focus is not only the release of some new mobile phones, but also the home of AI and 5G. For the hot theme of these two concepts, many technology giants are sparing no effort to sprint, and the annual exhibition has naturally become an important stage.
In terms of AI, this year Huawei AI mobile phone driven Porsche, Tencent and MediaTek released the AI ​​anti-virus engine, TouchPal brought the "most understand you" AI input method......
For 5G, at this year's Pakistan Exhibition, the most exciting people in China are Huawei's leading chipmakers such as Qualcomm, Apple, Samsung, etc., and the first to launch the world's first 5G commercial chip that meets 3GPP standards - Balong 5G01, and Based on the chip's first 3GPP standard 5G commercial terminal - Huawei 5G CPE, and announced that its first 5G smart phone will be available in the fourth quarter of 2019.
Although people are only looking at the doorway for the highly technical chips, the layman looks at the bustle. However, I believe that most of the audience who have paid attention to this exhibition, even the layman, will definitely feel the significance of Huawei's release of this 5G chip. The most intuitive message it brings is that the Chinese chip Huawei's chip technology has been successfully implemented. "Curve overtaking" is at the forefront of the world in the 5G field.
The layman saw the excitement brought by Huawei's 5G chip. From the perspective of the insider, how many doorways does the chip contain?
What is the 3GPP standard?Balong 5G01 is the world's first commercial 3G chip based on 3GPP standards. So what is the "3GPP standard"?
In fact, 3GPP is the largest international standards organization formed by the cooperation of seven global standards development organizations, including Japan Wireless Industry and Commerce Association, China Communications Standards Association, US Telecom Industry Solutions Alliance, Japan Telecommunications Technical Committee, Europe. Telecommunications Standards Association, Indian Telecommunications Standards Development Association and Korea Telecommunications Technology Association. In addition, 3GPP's mission is to develop and maintain global wireless communication standards.
At the end of last year, 3GPP completed the development of three 5G standards, namely "5G System Architecture", "5G System Process" and "5G System Strategy and Billing Control Architecture". They are the basic standards for defining and forming 5G network systems and determine the overall shape of the 5G network architecture.
Among them, "5G System Architecture" defines the architecture and network functions of 5G networks and the overall access capabilities of 5G systems. The specific content covers all aspects of roaming scenarios and non-roaming scenarios; "5G System Process" defines 5G users. Access and 5G service signaling procedures; and the 5G System Policy and Billing Control Architecture defines the 5G network policy control architecture, related functions, and billing architecture, for example, it includes billing control and traffic-oriented data flow. Online credit control, etc.
Huawei's 5G commercial chip, Balong 5G01, which is released in accordance with the 3GPP standard, clearly meets the above three relevant standards for 5G, and is truly an "authority certification".
Huawei 5G commercial chip - Balong 5G01Since it meets the requirements of the world's most authoritative 5G standard, what is the specific strength of Huawei's Balong 5G01? According to reports, it supports the mainstream 5G frequency band, including low frequency (Sub6GHz) and high frequency (mmWave millimeter wave). In theory, a data download rate of up to 2.3 Gbps can be achieved.
Among them, the 5G low-frequency commercial terminal measured the peak downlink rate of 2Gbps, which is equivalent to 20 times of 100M fiber. That is to say, in less than 1 second, you can download a set of network dramas and be backward compatible with 4G networks.
In addition, the chip also supports NSA (non-independent networking) and SA (independent networking) networking. In fact, this refers to the requirements for wireless network mobility. The mobility requirement management of the non-independent networking is responsible for the LTE base station and supports the addition and release of the 5G base station;
The mobility of the independent networking requires 5G cell selection and cell reselection in the 5G system, and supports the same frequency and inter-frequency handover, and supports 5G to LTE handover.
Overall, after the Balong 5G01 chip was released, Huawei has already demonstrated to the world that it has become the first company in the world to provide end-to-end 5G solutions for customers.
5G network and terminal are the two basic conditions for 5G commercial. For the terminal, the chip is the most important one, which is the key link for the development and maturity of the 5G industry. In fact, Huawei 5G chip has more cattle? In short, Huawei has mastered the chip, and it has mastered the extremely important right to speak.
