【Abstract】Huawei launched the innovative MBB (Mobile Broadband, Mobile Broadband) visualization solution PRS, which is part of Huawei’s SingleOSS solution. Maximize the value of MBB network.
Huawei, the world's leading provider of information and communication solutions, launched the innovative MBB (Mobile Broadband, Mobile Broadband) visualization solution PRS, which is part of Huawei's SingleOSS solution. Operators ensure user experience and maximize the value of MBB networks. In the MBB era, the penetration rate of smart terminals continues to increase, and data services grow exponentially, which has a huge impact on the performance and resources of MBB networks. How to quickly locate network performance problems and evaluate the usage of network resources is a common problem encountered by operators in network operation and maintenance. To help operators solve O&M problems, Huawei launched the leading PRS solution. Through the visualization of network KPI (Key Performance Indicator, key performance indicators) and abnormal events, PRS realizes the monitoring of network performance, and establishes KPI evaluation and analysis for GSM/WCDMA/LTE and other wireless access networks system. Using PRS, operators can quickly locate network KPI problems, analyze network abnormal events from the perspective of users and terminals, quickly respond to network faults, and ensure user experience. At the same time, PRS can also realize the visualization of network capacity and resource usage. Operators can see resource consumption such as devices, interfaces, boards, licenses, and air interfaces in the network, and quickly locate network capacity bottlenecks. Operators can see through network bandwidth, traffic, and signaling, and accurately establish signaling models to accurately plan MBB networks. Huawei PRS, an MBB visualization solution, will help operators realize efficient operation and maintenance of MBB networks
What are the network standards of the three major operators
At present, the network standards of Chinese operators are as follows:
The 3 modes of GSM (2G)/TD-SCDMA (3G)/TD-LTE (4G) used by China Mobile;
China Unicom uses GSM(2G)/WCDMA(3G)/TD-LTE(4G)/FDD-LTE(4G);
China Telecom uses CDMA1X(2G)/EVDO(3G)/TD-LTE(4G)/FDD-LTE(4G).
What are the 4G network standards supported by China Mobile, China Unicom, and China Telecom?
Hello
At present, the 4G network standards of the three major domestic operators are all TD-LTE and FDD-LTE hybrid networks.
What does MBB mean?
MBB: Mobile Broad Band, mobile broadband.
At present, public network operators use MBB as one of the main data growth points to transform and construct existing networks. The main technical means is WI-FI.
Mobile web (Mobile web) refers to the way of using mobile devices, such as mobile phones, PDAs or other portable tools to connect to the public network to achieve Internet access. Mobile networks do not require fixed devices for access. The mobile network mainly refers to browser-based Web services, such as World Wide Web, WAP and i-mode (Japan).
Glossary:
Mobile network refers to browser-based web services such as World Wide Web, WAP and i-mode (in Japan) using mobile devices such as cell phones, PDAs or other portable tools to connect to public networks: no desktop computer is required, nor a fixed fixed connect.
However, interoperability and usability issues remain with mobile network access today. This is due to a number of reasons including incompatible formats for the large amount of information available on the Internet for mobile devices and partly due to physical size limitations of small screens for mobile devices and other devices.
Where is Huawei's 5G strength? It can be seen from the "minimalist 5G"
"I want the United States to win through competition, not by blocking the current more advanced technology." On February 21, US President Trump sent the above tweet, revealing the real reason for his ban on Huawei's 5G.
On the same day, Ren Zhengfei, founder of Huawei, said in an interview with CBS TV in the United States that he thanked the Trump administration for promoting Huawei, which made Huawei 5G more influential and won more contracts.
The back and forth of the key figures has triggered domestic and foreign media to rush to report and ferment on social networks, which has confirmed and popularized the power of Huawei's 5G among a wider group of people.
But where is Huawei's 5G strength? In addition to the side support of the "opposition", what other direct evidence can prove it? Maybe many people don't know much about it.
In fact, even for technology enthusiasts, the current strong understanding of Huawei's 5G may be more at the level of patented technology, communication equipment and chip research and development; some people may even think that it is a very cost-effective product and on-call Services, so that global operators continue to be inseparable from Huawei.
Today, let's take a different perspective, from the transformation design of technology to business and the application level, to understand the strength of Huawei's 5G. The key lies in the "minimalist 5G" construction strategy that Huawei has been pursuing for a long time and has just officially released.
Prescribing the right medicine, Huawei released the "minimalist 5G" construction strategy
On February 20, local time, at the pre-communication meeting for the 2019 Mobile World Congress in London, Huawei released the "Simplified 5G" construction strategy, from the three aspects of network simplicity, automation, and business simplicity, to the future development of wireless networks. direction to make recommendations.
Subsequently, at the 2019 Mobile World Congress, which opened on the 25th, Huawei brought the practical results under the concept of "simplified 5G", fully exhibiting a comprehensive and leading mobile phone network built with simplified sites, simplified architecture, simplified protocols, and simplified O&M. End-to-end 5G products and solutions help operators rapidly deploy 5G networks on a large scale.
They are all 5G networks, and there are other ones that look different? ! How to understand Huawei's "minimalist 5G" construction strategy?
It turns out that Huawei, which has served the largest number of operators at home and abroad for a long time, has seen that after the long 2G, 3G, and 4G era, the complex network built layer by layer can no longer meet the needs of operators to continue to innovate services while reducing the proportion of OPEX expenditures. demands. The mismatch between investment and return makes some operators hesitate to upgrade their networks.
However, the 5G network with the characteristics of large bandwidth, low latency, and large connection actually contains huge new experience and business opportunities for new services, which cannot be neglected or ignored by operators. In order to speed up the time-to-market of operators' services and reduce network construction and maintenance costs, Huawei prescribes the right medicine and proposes to build an end-to-end minimalist network to achieve unified network bearer, agility, efficiency, and automatic intelligence—"Simplified 5G" came into being.
In terms of specific implementation, Huawei has given four directions, including simplified sites, simplified architecture, simplified protocols, and simplified operation and maintenance, that is, starting from the simplification of the physical network, and gradually building up the simplified network architecture, simplified network protocols, and simplified network operation and maintenance. , and finally form an end-to-end efficient, intelligent and convenient minimalist network.
"Minimalist 5G" condenses Huawei's 30-year skill
Behind the simplicity is often the complexity. It is not an easy task for operators to enjoy the "speed increase and fee reduction" network. In order to achieve "simplified 5G", Huawei has carried out a number of systematic innovations in terms of sites, architecture, protocols, and operation and maintenance. The profound accumulation has just turned the originally complicated 5G construction and operation and maintenance into a simple matter.
For example, in terms of site simplicity, operators not only need to consider the performance and form of the base station itself, but also consider the installation and deployment of workers. In this regard, Huawei has come up with a super blade base station (Super Blade Site) solution. By highly integrating equipment such as multi-band and multi-standard antennas, it has achieved unified access in multiple ways, as well as equipment miniaturization and modularization. Standardization and standardization make it as easy and convenient for operators to deploy 5G base stations as building blocks.
As another example, the above-mentioned super blade base station contains Huawei's world's first 5G base station core chip TIANGANG. This revolutionary chip with ultra-high integration, super computing power, and ultra-wide spectrum has brought a revolutionary The improvement of the base station has reduced the size of the base station by 55% and the weight by 23%. In practice, it is reported that 90% of the site upgrades do not require mains power transformation. At the same time, AAU integrates the radio frequency and antenna system together, eliminating the need for feeder cable connection and waterproofing of the feeder cable, which can save about 35% of the installation service man-hour.
For another example, in terms of simple operation and maintenance, based on the concept of autonomous driving network and the SoftCOM AI solution of full-stack and all-scenario AI infrastructure , Huawei has released a series of wireless network automation products including the MBB Automation Engine (MAE) solution. The solution can help operators save a large number of parameter configurations, improve site opening and O&M sales , and ultimately achieve doubling of energy efficiency, network performance, O&M efficiency, and user experience, and fully double the value of telecom networks.
To sum up, if 5G is a collection of a series of technologies, then it can be said that Huawei not only has the most complete technology reserve, but also is the single king of various technologies, and it is also a master who can integrate various technologies. It is no wonder that Neil McRae, chief architect of British Telecom, said, "There is only one real 5G supplier, and that is Huawei. Other suppliers need to work hard to catch up with Huawei."
The charm of "minimalist 5G" is amazing
There are often scenes like this in martial arts dramas: which one is more powerful, breaking a hard stone with a punch, or cutting a piece of paper neatly with a palm? Usually, the latter is a manifestation of having a higher level of martial arts. Huawei's "minimalist 5G" can be said to have this kind of higher "cultivation" that is as light as it is. This means that while other 5G providers are still focusing on solving the problem of 5G, Huawei has already begun to help operators create a more advanced "minimalist 5G".
On December 1 last year, South Korea's three major operators announced the official commercial use of 5G ahead of their global counterparts. As of the day of the release, South Korea has deployed 5,804 5G base stations, including 4,133 for LG U+, 854 for KT, and 817 for SK Telecom. Among them, LG U+, which started construction at the same time but is far ahead in terms of the number of base stations, also set a world record of building 1,367 5G base stations within 19 days. According to reports, the site planning and construction service provider behind LG U+ is none other than Huawei.
At the ongoing Mobile World Congress 2019, Huawei's "Simplified 5G" is also getting good news. On the 25th, Vodafone and Huawei jointly built the industry's best 5G ultimate experience zone in the center of Barcelona. Using Huawei's end-to-end product solutions, 5G base stations were completely deployed on existing LTE sites to efficiently build the highest quality 5G existing network , achieving a peak downlink rate of 1.7 Gbps, and an average rate of 800 Mbps.
On the 26th, South African mobile data network operator Rain announced a partnership with Huawei to jointly release South Africa's first 5G commercial network. Based on Huawei's end-to-end 5G solution, Rain has built a 5G network using the 3.6GHz spectrum, covering the main areas of Johannesburg in the first phase.
On the same day, Saudi Telecom Company (STC) also signed the "Aspiration Project" contract with Huawei, which includes end-to-end wireless network modernization and 5G network construction.
……
Statistics show that up to now, Huawei has obtained more than 30 5G commercial contracts, and the number of 5G base stations shipped exceeds 40,000 sites. Judging from the figures released by major equipment manufacturers, Huawei is far ahead. There is no doubt that the rising numbers and the praise of customers behind them largely reflect the charm of Huawei's "minimalist 5G".
In fact, even today, even the most stubborn "opposition" has begun to be convinced by Huawei's 5G and has begun to change its cognitive attitude. To deduce the reason, the absolute leading technology is the first. But in addition, Huawei's "minimalist 5G" designed based on the operator's OPEX considerations also contributed a lot.
The transformation from technology to business has never been a purely technical issue. Huawei's countermeasures can be said to be clear about the ideals and realities of operators. Faced with the expectations of individual users for the ultimate service experience and the demands of industry customers for digital transformation, a "minimalist 5G" network with excellent performance, good experience, easy and fast deployment, and low operating costs is what operators want network.
It is estimated that in 2019, more than 50 countries around the world will issue 5G spectrum, more than 60 operators will deploy 5G on a large scale, and more than 40 types of 5G commercial terminals will be launched. The first wave of 5G commercial use will cover a vast market of 1/3 of the population, which makes the speed and scale of 5G construction much higher than the same period of 3G and 4G. With the rapid advent of large-scale 5G commercial use, it is believed that Huawei's "minimalist 5G" will bring more surprises to people.
What are the network standards of China Mobile Unicom, 2G, 3G, and 4G? Thank you
For example, the 4G network standards of three domestic operators are as follows: Unicom 4G: TD-LTE, FDD-LTE Telecom 4G: TD-LTE, FDD-LTE Mobile 4G: TD-LTE In areas without 4G network coverage, China Unicom can be backward compatible with 3G networks, and the network speed can reach up to 42Mbps. It is the fastest 3G network in China and can also guarantee high-speed Internet experience.
