③ 400,000 base stations! China Telecommunications Union jointly builds the world's largest 5G SA network

From June 28 to July 1, the 2021 World Mobile Communications Conference arrived as scheduled. At the 5G Co-construction and Sharing Summit held on June 29, Zhang Xin, general manager of China Telecom’s 5G Co-construction and Sharing Working Group, said that since the full launch of the 5G network co-construction and sharing work in September 2019, China Telecom and China Unicom have built The world's largest 5G SA co-construction and shared commercial network. This not only has a strong repercussions on China's social development, economic promotion and global operators, but is also unprecedented in the history of the development of the global communications industry.

Three major challenges of 5G co-construction and sharing

Zhang Xin pointed out that China Telecom and China Unicom are the top 10 operators in the world. For two operators with such large scale, Although the resources of both parties are highly complementary, in the face of difficulties and challenges with no ready-made experience to follow, no standard technical solutions, and no successful cases to learn from, to achieve success in co-building and sharing 5G networks, we need to face and solve the following three problems.

First, there is the complexity of network management. As two operators with billions of users in the world, to carry out full 5G co-construction and sharing in the vast country of China, we need to face the resource status, planning goals, construction processes, maintenance standards, optimization strategies, etc. of both parties' networks. Differences in aspects require consideration of issues such as efficient organizational restructuring processes and collaborative management.

Secondly, network technology is uncertain. In order for the 5G network to simultaneously meet the network construction needs and user perception of the two operators, it must be coordinated in terms of technical standards, network evolution, user strategies, etc. There are no mature cases in the world to learn from, and it also requires technical research and innovative solutions.problem to solve.

Finally, there is the challenge of network operations. China Telecom and China Unicom have opened and operated more than 400,000 5G co-construction and shared base stations. How to solve the problems of visibility and management of network data of both parties, efficient and fair resource allocation, and ensuring mutual trust under the co-construction and sharing network are all issues of co-construction and sharing. Problems that need to be solved during shared network operations.

Facing the difficulties of 5G co-construction and sharing

Faced with complex network collaborative management issues, China Telecom and China Unicom established a cross-operator project team and established Full-time co-construction and sharing agencies at the group, provincial and municipal levels share the responsibilities of 5G planning, technology, mechanism, coordination and supervision, and have innovated the co-construction and sharing management organizational mechanism.

On the other hand, to optimize the process reconstruction, both parties seek common ground while reserving differences, reshape the process, and jointly formulate a series of processes such as planning, construction, maintenance, and optimization in accordance with the principles of unified planning, partition construction, collaborative maintenance, and joint optimization. , promoted the end-to-end collaboration of "planning, construction, maintenance, and optimization", fully utilized the resource endowments of both parties, doubled the scale, bandwidth, and speed, and led the customer perception.

Technological innovation of 5G co-construction and sharing

In terms of technological innovation, Zhang Xin said that an important prerequisite for network co-construction and sharing is to ensure the independence of the businesses of both parties. After extensive technical verification, China Telecom and China Unicom have adopted a technical solution for access network sharing, which avoids extensive customization and transformation of the core networks of both parties and meets the network requirements of logical end-to-end controllable, manageable and rapid deployment. 5G builds a shared network architecture with one physical network and two logical networks.

At the same time, since the industrial chain of SA network and terminals is not yet mature in the early stages of 5G commercialization, China Telecom and China Unicom have taken into consideration the strategies of both parties’ 4G network frequencies, network compounding, equipment manufacturer differences, and user experience, engineering Progress, maintenance difficulty and other factors, and after repeated technical demonstrations and field experiments, we were the first in the world to propose a single anchor point solution for NSA access network sharing, a double anchor point solution, anchor point concessions, anchor point priority and other series of sharing Plan to promote the transition technology plan of both parties from NSA to SA for rapid and smooth evolution. According to Zhang Xin, this solution can meet the requirements of different business scenarios based on the existing network load and user needs, and achieves the technical requirements of coexistence of NSA and SA in the early stage and independent SA networking in the later stage.

According to Zhang Xin, in the process of SA network evolution, both parties have broken through a series of SA's key evolution technical problems such as user data migration, automatic user default activation, SA VPDN, and compatibility of terminal and network key parameters. This ensures the stability and efficiency of the entire network evolution process, and the user experience is not affected.

First, it innovated the user data migration solution and realized the dynamic migration of single user data to the 5G network, avoiding the huge risk of one-time migration of massive user data and saving hundreds of millions of yuan in data migration customization network. The cost of 5G yuan not only reduces the cost for 5G usersThe cost of migration is reduced, and the user’s need to use 5G without changing cards or numbers is realized.

The second is to innovate the voice fallback solution. Voice service is the most basic service that affects user perception. Before VoNR has commercial capabilities, there will be differences in the 3G/4G voice bearer networks of both parties and inconsistent QoS policy configurations. In order to solve the problem, the two parties formulated a technical strategy plan for voice configuration to enable users on both sides to smoothly fall back to their respective networks and ensure that the voice service perception of users on both sides is not affected.

The third is innovative frequency solutions. China Telecom and China Unicom have proposed a solution to share 200M outdoors and 300M indoors. According to user needs and network load, flexible configuration on demand, independent carrier and shared carrier methods, It has reached a peak rate of 2.7Gbps for single users on the global C-BAND commercial network.

In addition, China Telecom and China Unicom have also conquered the core technical capabilities of software and hardware equipment.

First, the two parties have joined forces with upstream and downstream enterprises to break through the technical bottlenecks of key components such as 200M large-bandwidth highly integrated intermediate frequency chips and 3.5G GaN large-bandwidth power amplifier filters, promoting the development of large-bandwidth equipment in the mid-frequency band. The maturity of standards and industrial chains.

Second, in response to the problem of limited 3.5GHz sector coverage, both parties innovatively proposed 5G super uplink technology and incorporated the core standards of R16. Through frequency collaboration of 3.5GHz and 2.1GHz, network capacity and coverage performance are improved.

Third, in the face of the personalized customized network needs of various industries, we innovatively propose a slicing method that reserves PRB resources, which enables flexible isolation and sharing of wireless resources between different slices and ensures high security. Delivery of SLA.

Operational innovation of 5G co-construction and sharing

Faced with the difficulties and challenges of network operations, China Telecom and China Unicom actively responded with three major measures. First, the two parties have innovatively opened up the dual northbound interfaces of the power network management, making the network configuration parameters of both parties visible and checkable, ensuring the sharing of basic data and resource information, and realizing information interoperability. The second is the pioneering introduction of blockchain technology, using its decentralization, tamper-proof, traceability and other characteristics to ensure sharing through product applications such as key parameters on-chain certificate storage, two-way confirmation and empowerment of work orders, and smart contract scheduling. The network can be managed and trusted, and resources can be scheduled fairly and efficiently. Third, in the face of the high energy consumption problem of 5G, we built a 5G base station AI big data intelligent energy-saving platform to solve the unified base station intelligent energy-saving problems of the entire network, cross-vendors, and cross-4G/5G collaboration, making the comprehensive energy-saving efficiency of 5G base stations reach more than 15%.

At the end of the speech, Zhang Xin said that after two years of innovation and practice, China Telecom and China Unicom quickly built a high-quality 5G network covering all cities across the country, providing strong support for the development of the two 5G services. Strong network infrastructure guarantee. But Zhang Xin admitted frankly that there are still many issues that need to be explored and studied, such as how to update the network in a shared network environment.The ability to flexibly meet ToB application requirements and realize end-to-end slicing; how to empower blockchain and share network technology and operations; how to build a multi-party mutual trust mechanism; how to pool high-performance multi-frequency bands to quickly realize 2G/3G/ 4G spectrum re-farming.

"We hope to use the GSMA platform to work with operators, manufacturers and other industry partners to continue to conduct in-depth research on the technology, operations and evolution of shared networks." Zhang Xin said.
