Today, China Mobile led


This project, led by China Mobile, has solved the technical problem of mobile Internet End-to-End deployment of IPv6 and achieved the largest scale application in the world after more than ten years of research in combination with China Academy of information and communication, Tencent cloud computing company, Huawei Company and other units. A number of research results have reached the international leading level through appraisal.

With the development of mobile communication, mobile Internet has become the main carrier of the Internet. The problem of address exhaustion seriously restricts the development of the Internet in China, especially the mobile Internet. Promoting IPv6 scale deployment is of great significance for building a strong network country, accelerating the process of information technology in China, and helping the economic and social development. At the beginning of the project, there are great challenges in the evolution of mobile Internet to IPv6: first, there is a lack of comprehensive IPv6 transition program and technical standards; second, the end-to-end industry from terminal, network to application is not sound; third, all parties in the industry chain have insufficient confidence in IPv6 and poor support. However, it usually takes 10 years for mobile networks to be upgraded. Once 4G networks miss the support for IPv6, it will be difficult to apply on a large scale in the next few years.

This project seizes the development opportunity of the mobile network of the generation of ten years, combines the huge network and user scale of China Mobile, pulls the terminal and network industrial chain, and realizes the synchronous development of IPv6 and 4G networks. Under the support and promotion of this project, China Mobile has actually allocated IPv6 addresses to more than 700 million users, and built a dual stack 4G network with the largest scale of users in the world; meanwhile, it has promoted the use of IPv6 single stack for 4G voice service, and nearly 500 million users have used pure IPv6 for voice communication, making it the largest IPv6 single stack network in the world.


This project has realized a lot of independent innovation, proposed IPv6 Transition scenario, architecture and solutions, broke through PNat / BIH transition technology, optimized a number of basic protocols, and actively promoted the improvement of IPv6 standard system in IETF, 3GPP and other international organizations, led the development of IPv6 Transition international standards for mobile networks, and achieved the breakthrough of independent innovation in the next generation of Internet in China 。

The director of the project, the network of China Mobile Research Institute and the director of the IT Technology Research Institute, said:

In 5g era, IPv6's massive address space and protocol characteristics are highly consistent with the characteristics of 5g network, such as enhanced bandwidth, massive connection, ultra-low delay, etc., which strongly supports the development of 5g network, stimulates new business features and new modes, and helps the development of 5g vertical industry. Under the strategic guidance of the national action plan for promoting IPv6 scale deployment, China Mobile will fully grasp the key opportunity of 5g network construction and development, fully deploy IPv6 in 5g network, and create a new ecology of the next generation Internet.
