    SKT, Samsung complete 5G NSA call

    SK Telecom and Samsung Electronics have completed a 5G call using 3GPP non-standalone new radio standards and commercial 5G new radio equipment. The trial at SK Telecom’s 5G testbed at its Bundang office building used end-to-end solutions jointly developed by the two South Korean companies. It utilized 100MHz of 3.5-GHz 5G spectrum and 5G NR, LTE radio and 5G non-standalone core infrastructure.

    The 5G non-standalone new radio architecture has been designed to allow 5G to be supported by legacy LTE infrastructure, allowing mobile devices to be connected to both 4G and 5G for data traffic, and to use the 4G network for non-data traffic  such as exchanging signals for mobility controls.

    This configuration is expected to be one of the promising 5G architectures for initial deployments.

    Sasmsung announced last month that it has secured a contract to deliver 5G equipment including core and RAN technologies for SK Telecom’s 5G deployments, which will commence later this year.

    The companies have been collaborating on 5G development since 2014, and jointly completed the first successful interworking of LTE and 5G new radio utilizing both 3.5-GHz and 28-GHz spectrum during a trial last year.

    Huawei completes 5G NSA core network test

    Huawei said it has become the first vendor to pass China’s 5G Non-Standalone (NSA) core network test, which constitutes an important part of the country’s 5G R&D trials for operators that hope to deploy 5G commercial networks early and quickly.

    The test, which covers key core network technologies and service processes, was part of the third phase trial organized by the IMT-2020 Promotion Group and conducted at the Beijing lab of the China Academy of Information and Communications Technology (CAICT).

    The test is based on the commercial 5G core network solution released by Huawei at the Mobile World Congress 2018. 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.

    China’s three major carriers – China Mobile, China Telecom and China Unicom – as well as the network technology workgroup of the CAICT were involved in the network test, Huawei said.

    As of year-end 2017, Huawei had built 15 pre-commercial 5G core sites around the globe.
