Huawei claims that it is the first vendor to pass China’s 5G non-standalone (NSA) Core Network test.
The test, which covers key Core Network technologies and service processes, is the third phase of the 5G R&D trial. The trial was organized by the IMT-2020 (5G) Promotion Group and conducted at the Beijing lab of the China Academy of Information and Communications Technology (CAICT). The test constitutes an important part of China's 5G R&D trials for operators that hope to deploy 5G commercial networks early and quickly.
The test is based on the commercial 5G Core Network solution released by Huawei at the Mobile World Congress 2018. The technologies tested include: gateway selection in control and user plane separation (CUPS) architecture, 5G ultra-high bandwidth, dual-connection to LTE and new radio (NR), independent billing for 5G NR, and terminal access management.
The key service processes include: terminal registration, service requests, mobility management, and session management.
The 5G network test was performed by the network technology workgroup of the CAICT and three of China’s leading operators, China Mobile, China Telecom and China Unicom.
According to Huawei, in the first and second phases of the 5G R&D trial, Huawei's 5G core network also achieved outstanding results in verification of key technologies and prototypes such as Service-Based Architecture (SBA), Network Slicing, and Multi-access Edge Computing (MEC).
