Have you ever eaten hot pot? Once upon a time, such a delicacy became the representative of the Chinese. In various variety shows that travel abroad, hot pot once became a reward for stars. It is an original Chinese food with a long history and is a food for all ages. Among the many different types of hot pot, the mention of Jiugongge hot pot must be known to everyone. However, in the process of 5G network landing, there is also a technology comparable to Jiugongge hotpot, that is-5G network slicing technology.

5G network slicing technology is like a Jiugongge hot pot

5G network slicing technology is an on-demand networking method in the process of 5G network commercialization, which allows operators to separate multiple virtual end-to-end networks on the same technical equipment. The access network bearer network is logically isolated on the core network to adapt to various types of applications. In short, 5G network slicing is like a nine-square grid hot pot, which seems to have only one cooking pot, but through different grids and various flavors to meet the needs of different diners, each grid is relatively independent on the one hand, On the other hand, it forms an organic whole, meeting the different needs of the whole table through a hot pot, just like 5G network slicing under the same network, slicing services for the needs of different application scenarios.

The three categories correspond to the three major application scenarios of 5G

At present, many recognized 5G network slices in the industry are divided into three scenarios: eMBB slice (enhanced mobile broadband communication), uRLLC slice (high reliability and low latency communication), mMTC slice (mass machine type communication). Each type of slice service includes many application types. Take eMBB slice as an example, which includes cloud game sub-slice, virtual reality sub-slice, smartphone sub-slice, etc.; uRLLC slice includes autonomous driving sub-slice, industrial Control sub-slices and more.

In fact, it is not difficult to see from the sub-slice services included in these slice services that the services corresponding to each slice service have different network requirements. For example, an extremely typical vertical industry application in 5G—autonomous driving requires low latency and high reliability; in industrial control scenarios, the network speed requirements are not high, but the reliability requirements are much higher than other vertical industry applications and many more.

In contrast, for terminal applications such as cloud games, AR/VR, and 5G mobile phones that are closer to consumers, more emphasis is placed on the high-speed and high-throughput network characteristics of 5G to better serve end users.

5G network slicing and 5G terminal slicing need to work together

The previous part mostly talked about the application scenarios corresponding to 5G network slicing, and what can be used for slicing and how to do it is a more realistic question. A few days ago, at the China Mobile Global Partner Conference held in Guangzhou, China Mobile, together with UNISOC, ZTE and other industry chain partners, jointly completed the industry’s first application demonstration of the 5G terminal slicing target solution, which indicates that 5G terminals have The slicing capability can provide personalized and customized services for 5G users.

Online speed test demo

It is understood that the on-site demonstration mainly relies on the 5G SA independent networking deployed and constructed by China Mobile. Through ZTE’s 5G system equipment, the 5G terminal slicing target solution was successfully demonstrated on the terminal based on Zhanrui 5G chip.

The 5G network slicing technology first requires the network to be deployed in the cloud. Starting from the core network, it is divided into public networks and industry-specific networks through slicing. Industry specialties can be further subdivided into ordinary users and special users. The core network layer begins to be hierarchically layered. Subsequently, at the transmission network level, corresponding slicing guarantees are also required, and at the same time, the wireless network must also be guaranteed by corresponding slicing technologies. After the network level is ready, the next step is to come to the 5G terminal level for cooperation.

There is an unchanging law in the development of communication technology, that is, the end-to-end network must be coordinated. As long as the network does not have the cooperation of the terminal, there is no way for any service to finally land. Performing 5G network slicing at the terminal level is also a complex task, mainly because the terminal itself has a complex system, including applications, operating systems, baseband chips, etc. When performing 5G terminal network slicing, it is necessary to Applications, operating systems, and baseband chips must be connected to enable slices to match the network slices on the terminal.

The 5G terminal slicing target solution enables 5G terminals to have slicing enhanced service capabilities based on APP ID, FQDN, IP triplet, customized DNN and other service granularities. This means that slicing can not only provide differentiated services based on different services, but also effectively isolate the same type of traffic, and even provide differentiated personalized services for different users for the same type of service, supporting new business models, such as cloud Games, live video, HD video playback, etc.

Specifically, such a demonstration is a good proof. This demonstration uses the online speed measurement service scenario to intuitively show the service experience comparison between non-sliced ​​network access and slicing guaranteed network access. From the perspectives of downlink peak rate, packet loss rate, delay, etc. Excellent performance in typical business, fully realized 5G terminal slicing target solution and modem centralization solution. The demonstration results show that even under simulated network congestion, 5G slice users can still enjoy a smooth download rate, extremely low packet loss rate and ultra-low latency service experience.

The first 5G network slicing technology eSIM version of CPE was born

If the 5G terminal network slicing jointly realized by UNISOC and China Mobile and other partners is an experiment based on actual application scenarios, then the world’s first 5G CPE VN007+ that supports complete 3GPP standardized network slicing and eSIM jointly built with China Unicom It is a good example of the practical application of 5G terminal slicing.

China Unicom and UNISOC have completed the verification of VN007+ in the end-to-end 5G network slicing solution. After the network slicing is officially commercialized, VN007+ will greatly reduce the threshold for 5G network slicing of existing terminals, and can quickly enrich 5G application scenarios. According to the data, VN007+ can be carried and laid according to the actual needs of users, and can be widely used in multiple industries and life application scenarios. The networking is flexible and can meet the fast network adaptation of various scenarios.

Industry application: It can be widely used in smart factories, smart transportation, smart agriculture, smart energy, smart medical care, mobile live broadcast and other scenarios.

Small and medium-sized businesses: meet the needs of retail stores, small and medium-sized enterprises and personal Internet offices, and support multi-user, high-speed, and stable access at different locations.

Live broadcast: Meet the network requirements of the We Media team for high transmission rate, easy portability, and ease of use.

Temporary places, areas not covered by optical fiber: “Blind-blind” broadband. Major temporary hospitals, factories, scenic spots, construction sites.

Family life scene: to meet the needs of home and rental groups, plug and play, easy to install.

The implementation of 5G network slicing benefits users across the industry

The implementation of 5G network slicing will ultimately benefit the development of the entire 5G industry. Both operators and end-user consumers can benefit from the implementation of such a new technology.

At the operator level, 5G network slicing provides operators with a means for more refined network operations, and more refined operations can allow operators to have more sources of income. For example, in the face of users in different industries, operators can provide virtual private networks that meet their needs for different users. On the one hand, it allows industry users to deploy flexibly, and can apply when they need it and when they don’t need it. Cancellation at will, greatly saving the cost of deploying private network for industry customers.

For ordinary consumers, 5G network slicing can also change the existing consumption method of simply paying for traffic in the 4G era, so that every package fee can be better spent on the cutting edge. In the existing consumption model, if 5G is compared to 100M resources, then all consumers are paying for the 100M resources. Not only is the package per person very expensive, but the user experience is not good. In addition, for example, the “low latency” feature of 5G networks may not be available to most users, so it is naturally not cost-effective to pay for an unused feature. After the implementation of 5G network slicing, users can obtain more customized network services from operators according to their own needs and characteristics, which also reduces the cost of using the network for ordinary consumers from another level.

UNISOC’s advantages in the development of 5G network slicing

So the question is, what are the advantages of UNISOC, which is cooperating with various operators to realize 5G network slicing? Taking the current 5G terminal network slicing solution provided by UNISOC as an example, its advantages are mainly reflected in:

1. Application adaptation

Both existing and newly developed applications can access network slices without perception.

2. Operating system adaptation

At present, Zhanrui’s solution can be adapted to all terminal operating systems.

3. Adaptation of different types of terminal products

At present, through UNISOC’s solutions, various pan-intelligent terminals including smartphones and CPEs can be connected to network slicing.

4. Good cooperation with operators

UNISOC is currently working with operators to formulate URSP rules, which is more flexible and convenient.

write at the end

Network slicing technology is undoubtedly one of the important technologies for the future application of 5G network. In the early stage of 5G network application, on the one hand, it enriches the types of services that operators can provide; on the other hand, it satisfies the different network usage of end users and industry users. On the one hand, it reduces the cost of providing dedicated networks for operators; on the other hand, it also reduces the overall network usage costs for end users and industry users. Many conveniences will undoubtedly make 5G network slicing technology widely popularized. Ziguang Zhanrui has undoubtedly been at the forefront of the industry with its own technical advantages. Through the good configuration and connection of 5G network slicing on the terminal side, 5G network slicing can better achieve end-to-end network collaboration and accelerate the implementation of technology and application, and promote the development of the whole 5G industry.
