Today, more and more industries in the physical world are intersecting with the digital world, changing the way we live.

For example, the government-specific network "folds" government departments in the physical world and city residents together in the digital world through a dedicated network, allowing people to enjoy high-quality government services without leaving home.

Digital upgrades were first promoted to the Internet. If you were to write a story about the upgrade of the Guangdong government affairs network, the opening chapter might be called "Qingyuan Folding".

China Mobile Guangdong Company Qingyuan Branch (hereinafter referred to as "Qingyuan Mobile") actively researches and promotes the application of IPv6+-enabled SPN technical solutions. With the help of "IPv6+" ultra-wide, wide connection, determinism and low latency capabilities, it expands the scope of 5G applications, improves experience, and explores the application of new Internet in the government field. It has successfully deployed the province's first end-to-end SPN government-enterprise network.

This private network utilizes SPN small-particle technology to achieve multiple planes in one network, optimal TCO, ultra-low latency, and ultra-high reliability, becoming a digital private network with "zero lag", "zero interruption", and "zero waiting".

Let's open this book "Qingyuan Folding" and see how Qingyuan, Guangdong "folds" digital government affairs and district residents together, bringing digital government from the future to the present.

Digital government affairs have gradually penetrated from the national, provincial and municipal levels to the county, township and village levels. How far has it progressed?

The answer may have to be found from real positions and needs. They are the protagonists of "Qingyuan Fold":

Xiao Li, a "village official" who visits villages and households, collected a large amount of forms, photos, videos and other information. He was worried that uploading them to the private network with his mobile phone was not safe enough, so he had to wait until he returned to his desk to upload them. Overtime work became commonplace.

Grandma Zhao, a villager, was very happy to hear that the health center can now provide remote medical consultations. She finally didn't have to wait for her children to come home and trouble them to send her to the county hospital. However, she found out that the village's network bandwidth could not support real-time consultations with ultra-high-definition medical videos.

Officer Hu from the Qingyuan Fire Brigade received a task to conduct emergency rescue work during the summer flood season. When he arrived at the site, he found that the only optical cable had been cut, so he could not access the network and his business was forced to be interrupted...

The people of Qingyuan have been waiting and waiting, but why is digital government affairs still in the realm of science fiction and urban legends, and has not really entered their lives?

This brings us to the practical challenges brought by the "traditional government-specific network", which mainly include the following aspects:

One is insufficient bandwidth.The existing network equipment is outdated and has insufficient bandwidth, with most having an access capacity of 20Mbps, which is insufficient to support business needs such as high-definition video conferencing, emergency command and dispatch, and government document transmission.

The second is security risk.The existing network security protection is weak, and large-scale terminal access is vulnerable to attacks, making it difficult to meet the trends of mobile office and rural services.

Third, the cost is relatively high.Each commission, office and bureau of the traditional government affairs network has to build its own network, with multiple networks coexisting in seven countries and eight systems. From urban areas to counties, villages and towns, there are many outlets, a large demand for equipment, and the size of IT personnel must also increase accordingly. Network construction is difficult, maintenance costs are high, and the learning cost for personnel is high.

Fourth, it is difficult to evolve.Most of the existing self-built networks of Qingyuan Municipal Government's government-specific network do not support IPv6 evolution capabilities and are unable to meet business needs. If each commission, office or bureau independently builds its own network, it will be subject to the policy constraint that "in principle, all regions and departments will no longer build new business-specific networks."

Therefore, under the leadership of Qingyuan Government and Digital Bureau, Qingyuan City started exploring the application of new Internet in the field of government affairs.

Upgrading the government-specific network will allow more residents to have "zero distance" access to government services, which is an inevitable choice for Qingyuan City to improve the level of digital government services.

The question is, who will do it and how?

The various commissions, offices and bureaus in Qingyuan City have different responsibilities, and their businesses require network isolation and carrying; to reduce the number of trips for the people, branch outlets must cover cities, counties, streets/towns, communities/villages, and the outlets are large and scattered; government investment must be used where it counts, so the network construction requires the best TCO (total cost of ownership). In addition, considering the security of government information, domestic technology must be used. Who has the ability to build this government-specific network?

Operators have natural network advantages and can provide high-performance, wide-coverage 5G mobile networks. SPN is a Chinese original technical standard led by China Mobile, and has achieved seven ITU-T international standard projects. In theory, through SPN end-to-end slicing enablement, and then superimposed with a wide-coverage 5G network, the chemical reaction released by SPN+5G can build a high-performance, highly reliable communication network that meets the needs of government and enterprise users. Qingyuan Mobile's SPN network is the most suitable.

Even though we have the right person, things are not easy.

Qingyuan Mobile told us that the upgrade and reconstruction of the entire municipal government network system not only considers cost and performance, but also comprehensively considers high availability, load balancing, reliability, scalability, and unified network management and centralized monitoring. Among them, the selection of transmission and data communication equipment is the main difficulty.

After the project was launched, Qingyuan Mobile had two options:

The first is traditional networking.The use of traditional transmission networks can complete the rapid delivery of projects, but it cannot meet the future development of "one network, multiple planes" and will continue to increase the use costs of government departments in the later stage.

The second is the SPN+5G solution.The advantage of this solution is its advanced technology. At the SPN Slicing Private Line Conference held in June 2022, according to the test data officially released by China Mobile,SPN has ultra-low latency, ultra-high precision synchronization, and hard slicing features, achieving multiple performance breakthroughs and significantly improving performance compared to traditional transmission technologies., where the single-node forwarding delay is only 1/20 of that of traditional transmission technology, and the delay jitter is only 1/100 of that of traditional solutions. However, the difficulty lies in the fact that there is no precedent for end-to-end SPN government and enterprise networks in the province, and whether the deployment can be successfully completed faces many unknowns and uncertainties.

Faced with this situation, Qingyuan Mobile conducted research and study in many locations, and ultimately established an end-to-end SPN private network solution.

The reason for their determination is, on the one hand, the responsibility of state-owned enterprises. A high-quality government-specific network is the cornerstone of Qingyuan's digital government construction, and long-term benefits must not be sacrificed due to fear of difficulties. Therefore, Qingyuan Mobile played the role of the main force of the network power and decided to bring the advanced SPN solution of "zero lag", "zero interruption" and "zero waiting" to Qingyuan.

On the other hand, there is the in-depth cooperation with our partner Huawei.

Huawei continues to invest in SPN small-particle slicing technology to build industry-leading solution capabilities.As early as 2022, Guangdong Mobile and Huawei jointly launched the "FOCUS Private Network Industry Solution", using the SPN solution to help upgrade various industry services such as government private networks, medical private networks, education private networks, and cloud private networks. The two parties have a deep cooperation foundation, which also gives Qingyuan Mobile confidence to build the province's first end-to-end SPN private network.

At this point, Qingyuan Mobile has made the firm choice of "folding" the SPN small-particle technology with the Qingyuan government network to create a "new quality Internet" in the government field.

After the plan was finalized, Qingyuan Mobile started building the province's first SPN government and enterprise network.

Due to the lack of precedent, tight time and heavy tasks, the construction pressure was quite high. However, Qingyuan Mobile did not back down. Through close cooperation and efficient communication, it finally completed the service opening task two days ahead of schedule, connecting nearly 2,800 institutions in Qingyuan and forming the province's first end-to-end SPN government and enterprise network.

This network can be summarized in three words:

1. High quality.SPN end-to-end slicing is enabled, and SLAs such as bandwidth and latency can be guaranteed, ensuring the smooth and stable operation of the business of government departments at all levels in Qingyuan. Whether it is transmitting and publishing videos, holding high-definition video conferences, remote real-time diagnosis and treatment, online education, etc., there will be no more lags, and there have been zero failures and zero complaints since the project was put into trial operation.

2. High efficiency.Relying on the widely covered 5G mobile network, the SPN government-specific network enables ultra-fast service provision, allowing "zero waiting" for services, which are available immediately like water and electricity. It supports "one dedicated line, multiple dedicated networks", improving the quality of the network, reducing costs and increasing efficiency.

3. High reliability.This solution combines with dedicated line guards to achieve comprehensive security protection of the "end", "pipe" and "cloud" for key government services, so that personnel from various commissions, offices and bureaus can work on the move with confidence; the end access SPN 5G CPE backup route, in the event of a wired network interruption, the 5G government dedicated network can be used to quickly switch to the 5G air channel, so that the service "never drops offline", and in emergency scenarios such as severe weather such as floods, ice and snow disasters, the network connection remains stable.

People connected by this network sincerely sighed: "It feels like digital government affairs have really arrived."

From the story of "Qingyuan Folding", we can feel the chain reaction brought to the local area by the "new quality connection power" of the province's first SPN government-enterprise network.

First of all, the network has changed.

At present, Qingyuan City's e-government external network has integrated and built multiple plane applications such as statistical planes and convenience service center planes, gaining a far-leading competitive advantage in the industry.

On this basis, the operators' business model has changed.

At present, more and more government departments and enterprises and institutions have proposed to "make full use of the connectivity convenience of the e-government external network, such as wide coverage and multiple access units, and integrate and connect to the network based on the e-government external network" to better interact with the digital government for data and business. The successful deployment of this project has reduced the number of businesses to a certain extent, and Qingyuan Mobile has also transformed from pursuing the number of dedicated lines to improving service quality.

Next, the dedicated government service lines built by operators will serve as the cornerstone of Qingyuan’s digital government construction, supporting local exploration of more possibilities for digital government services.

It is revealed that in the future,Qingyuan Mobile will continue to work with Huawei to explore SPN slicing and one-network-multiple-use application scenarios to ensure the stable and secure operation of more government and enterprise services, and combine SPN+5G fixed-mobile convergence capabilities., enabling ubiquitous access for government and enterprises, connecting urban terminals and blind spots, meeting access demands for mobile office, mobile law enforcement, urban IoT perception, and remote rural coverage, and achieving full business access.

Through this "Qingyuan Fold", we see how Qingyuan Mobile combines the needs of government and enterprises with advanced technology, and uses a new quality Internet to "fold" digital government affairs into the real life of the general public.
