Анатомия User Plane в 5G: разбираемся, как все устроено

Привет всем! Меня зовут Саша Иргер, я эксперт по разработке ПО в департаменте проектирования и разработки пакетного ядра сети в YADRO. Вчера мой коллега опубликовал на Хабре статью про Policy Control : как и зачем классифицировать трафик в сотовой сети. Сегодня продолжу тему и разберу, как конкретно работает User Plane. По сути, он организован так, чтобы удовлетворить требования от Policy Control. Давайте посмотрим, что здесь интересного.

Policy and Charging Control: зачем классифицировать трафик в сотовой сети и как это сделать

Привет, Хабр! Меня зовут Влад Редров, я старший инженер-программист в отделе разработки компонентов опорной сети 5G в YADRO. Сегодня расскажу про Policy and Charging Control (PCC): будем ставить проблемы, а потом через способы их решения наращивать набор PCC-фич и осознавать логику их работы. Разберем, как ограничивать скорость сессии для каждого мобильного устройства через Session-AMBR и QoS-характеристики, применять QoS-характеристики к разным сервисам, тарифицировать каждый сервис отдельно и еще много всего интересного. Погнали!

Почему в России так активно убивают 3G? Технический разбор неочевидной причины

Отключение 3G — общемировой тренд: операторы в США, Европе и Азии тоже высвобождают частоты под более эффективные 4G и 5G. Однако в России этот процесс имеет свои особенности. Здесь он идёт не только в русле технологического прогресса, но и накладывается на ужесточение правил и процедур вокруг интернета и мобильной связи. Если на Западе основной драйвер — экономика, то в российских реалиях архитектурные изменения сети чаще резонируют с задачами мониторинга и регуляторного контроля. Итак, к теме

Very interesting applied security research into the #GSMA #eSIM universe, specfically the use of the JavaCard VM with its questionable security architecture depending on an off-card bytecode verifier in the context of the eUICC which inherently contains eSIM profiles of different [competing] mobile operators, each of which can install arbitrary Java applets into the same eUICC. #GSM #3GPP #cellular #simcards

In principle, for the first time, the type of long-range ODFM/OFDMA planetary exploration wireless network that #SFU has been advocating and supporting at NASA and CSA, in collaboration with CU Boulder and Mars Institute and SETI Institute, since the late 1990s was transmitted by #Nokia Bell Labs on the lunar surface last week. But it couldn't be tested end-to-end. Slowly, though, space wireless is progressing (especially via #CCSDS standards):

One advantage Huawei had was the backing of its government.

US and European observers say China packs standards meetings with engineers who can be eyes and ears on the ground.

Rivals also complain that Chinese companies work together in lockstep; even ostensible competitors will set aside differences to support a compatriot business.

For a brief moment in the middle of 2016, it looked as if that national wall of support wouldn't hold.

In a preliminary round of the 5G New Radio standards process, the Chinese company #Lenovo expressed its preference for LDPC, because it was a more familiar technology.

That didn't last long.
Lenovo changed its opinion later that year.

Lenovo's founder, Liu Chuanzhi, called Ren Zhengfei to make sure that no offense was taken by the original stance.
Liu and other executives even drafted an open letter that read like a forced confession.

“We all agree that Chinese enterprises should be united and not be provoked by outsiders,” Liu and his colleagues wrote. “Stick to it … raise the banner of national industry, and finally defeat the international giants.”

Thus united behind polar codes, Chinese industry prepared to do battle at the final, critical stage
—the November 2016 engineering standards meetings held in Reno, Nevada.

The venue was the Peppermill resort and casino. Engineers, hunkered in hotel conference rooms arguing about block codes and channel capacity, had little time to enjoy the craps tables or eucalyptus steam rooms.

Simultaneous meetings to determine a number of standards kept engineers hopping from one conference room to the next, says Michael Thelander, a consultant specializing in wireless telecommunications.

“But polar coding versus LDPC, that was the hot topic,” he says.

On the night of Friday, November 18, the conference room was packed, and the meeting, which began in the evening, turned into a standoff.

Each company presented its work, including its testing results.

“The battle was pretty well drawn, with most of the Western vendors lining up behind LDPC,” says Kevin Krewell, a principal analyst at Tirias Research, who follows 5G.

Some Western companies backed polar codes too, but, significantly, all the Chinese companies did.

“There was no obvious winner in the whole game, but it was very clear that Huawei was not going to back down,” says Thelander, who was on the scene as an observer.

Neither would the LDPC side. “So we can sit there and spend six months fighting over this thing and delay 5G, or we compromise.”

So they did.
The standards committee split the signal-processing standard into two parts.

One technology could be used to send the #user #data.

The other would be applied to what was known as the #control #channel, which manages how that data moves.

The first function was assigned to LDPC, and the second to polar codes.

It was well into the wee hours when the agreement was finalized.

Huawei was ecstatic.
But it was not just Huawei's win; it was China's too.
Finally, a Chinese company was getting respect commensurate with its increasingly dominant power in the marketplace.

“Huawei-backed polar code entering the 5G standard has a symbolic meaning,” one observer told a reporter at the time.

“This is the first time a Chinese company has entered a telecommunications framework agreement, winning the right to be heard.”

Qualcomm professes to be fine with the result.
“It was very important for Huawei to get something,” says its CEO, Steve Mollenkopf.

“Huawei is actually quite good. They are a formidable company. And I think that's one thing that people need to acknowledge.”

Reaching consensus on the parts of a mobile platform is complicated. Decisions have to be made about dozens of specifications for transmission speeds, radio frequencies, security architecture, and the like.

To make that happen, engineers gather in a series of meetings every year to choose which new technologies will be deemed #standard in the next generation.

The stakes are high: The companies that provide the fundamental technology for 5G will be embedded in a global communications system for years to come.

So in the background are financial, nationalistic, and even geopolitical considerations.

“From the year 2001 to the present—three administrations—not enough attention has been paid to this,” says #Reed #Hundt, a former Federal Communications Commission chair during the Clinton administration.

Hundt is one of a number of current and former officials alarmed that the United States has no equivalent to Huawei
—that is, a major telecommunications company that both develops next-generation technology and builds it into equipment.

“In Europe, they have an Ericsson.
In Japan, they have companies.

And in China, they have not just Huawei but also ZTE.

But Huawei is the one that covers the whole range of products.”

All of this made Huawei's 5G standards bid an alarming prospect.

“Huawei's IP and standards are the wedge they intend to use to pry open the Western computing world,” Hundt says.

The body that develops 5G standards, the 3rd Generation Partnership Project ( #3GPP ), is an international umbrella organization of various telecommunications groups.

In 2016, it made a key decision on what was called #5G #New #Radio #standards
—the part that helped determine how data would be sent over 5G and how it would be checked for accuracy.

After spending millions, undergoing years of testing, and filing for multiple patents, Huawei was not going to pull punches at the critical juncture. It needed the certification of an official standard to cement its claim.

The problem was that reasonable people argued that other techniques would work just as well as polar codes to achieve error correction in the new framework.

Some suggested that a revamp of the current 4G protocol, turbo codes, would be sufficient.

Others, notably San Diego-based #Qualcomm, which makes chipsets for mobile technology, liked a third option:
Robert Gallager's old #LDPC idea, the one that had nearly reached the Shannon limit and had inspired Arıkan on his own intellectual journey.

Since the early 1960s, when Gallager proposed LDPC, technology had improved and the cost of commercial production was no longer prohibitive.

Qualcomm's R&D team developed it for 5G.

Though Erdal Arıkan did not know it at the time, his work would be squared off against that of his mentor in a competition that involved billions of dollars and an international clash of reputations.
