On June 13, 2018, San Diego, USA, the 3GPP 5G NR Standard SA (Standalone, Independent Networking) program was officially completed and released at the 80th TSG RAN Plenary of 3GPP, marking the official launch of the first truly complete international 5G standard. Datang Telecom Group has made important contributions to key technologies such as large-scale antennas, ultra-dense networking, mobility management, vehicle networking, new multiple access technologies, channel coding, and system design such as 5G TDD air interface transmission and network architecture.

Previously, 3GPP released an early version of 5G Release 15 based on NSA (non-standalone) architecture in December 2017. The non-independent networking standard is a 5G network based on the NSA architecture. Since the 5G air interface carrier only carries user data, the system-level service control still needs to rely on the 4G network. This method can be regarded as adding a new carrier to the existing 4G network. Expand the capacity. Due to the core network and control plane of the 4G system, the NSA architecture will not be able to fully utilize the low-latency technical features of the 5G system, and it will not be able to flexibly support diversified service requirements through features such as network slicing and mobile edge computing.
The 5G Release15 full version SA released this time is a new architecture with a new design concept. While introducing new network elements and interfaces, it will also adopt new technologies such as network virtualization and software-defined networks on a large scale. 5G independent networking can reduce the dependence on existing 4G networks, better support 5G large bandwidth, low latency and large connections, and provide customized services according to scenarios to meet the business needs of various users. To greatly enhance the customer experience.
The release of the SA independent network version means that the 5G system based on the independent networking architecture can truly realize the 5G technical indicators and commitments, and create more development opportunities for the mobile communication industry.

Datang Telecom Group fully participates in the formulation of international mobile communication standards. It has the functions of chairman and vice-chairman in international organizations such as ITU, 3GPP and oneM2M. It also serves as the chairman and team leader in the domestic CCSA and IMT-2020 promotion groups. Actively participate in international standardization management, as well as the development of rules and procedures. Up to now, Datang Telecom Group has submitted nearly 5,000 international standardization documents. In 5G technology research and standard competition, Datang Telecom Group has large-scale antenna and beamforming, new multi-access technology, ultra-dense networking, vehicle networking, channel coding, new mobility management, TDD dynamic frame structure, 5G core network. The 5G standardization field such as architecture and 5G CU/DU architecture design is at the international advanced level, and many technical solutions have entered the international core standard. Datang will develop an end-to-end full range of products including wireless, transmission and core network based on the latest R15 SA standard, helping the deployment of national 5G technology trials and scale trial networks, and promoting important vertical industry applications such as Internet of Vehicles and Industrial Internet. Landing, to achieve the goal of 5G network large bandwidth, low latency and massive connection, to contribute to the realization of China's 5G leading strategic goals, to promote the mobile communications industry has become one of China's few high-tech fields with industry voice and international competitiveness.
