KDDI Conducts 5G-Focused DCSG Trial
March 9, 2021
KDDI Research, MobiCom, and the Telecom Infra Project (TIP) launched an
interoperability trial spanning Japan and Mongolia which aim to evaluate the
potentials of open and disaggregated approach, enabling multiple combinations of
hardware and software makers, to building a 5G network.
Traditionally, hardware and software of conventional telecom equipment is
aggregated by each particular maker to meet specific purpose. However, there is
a growing demand in the industry for new and innovative open and disaggregated
solutions which enables network operators to timely and flexibly meet
diversifying requirements of consumers and enterprises, such as private 5G use
KDDI and KDDI Research are exploring how open and disaggregated RAN, transport
and core equipment can lower network costs and accelerate the deployment of 5G
networks. In the Telecom Infra Project (TIP [Jump to the applicable section2])
Community Lab, KDDI and KDDI Research have conducted fundamental test of TIP's
Disaggregated Cell Site Gateway (DCSG) equipment for accommodating base stations
and fixed broadband services in access network.
based on the understandings obtained by fundamental test of VPN functions etc.,
KDDI, KDDI Research and MobiCom are now launching an interoperability trial of
DCSG with aggregation transport equipment (i.e., Packet Transport Network and
IPRAN) and core equipment (i.e., IP core and mobile core). The scope of the test
has been expanded from KDDI and TIP community to also include wider connectivity
stakeholders, like a broader range of network equipment and operators. The
primary outcome of the trial will be to identify the challenges of moving this
technology toward to large scale commercial rollouts.
David Hutton, Chief Engineer at TIP, commented on the trial: "TIP sees the
trials of the DCSG and aggregation transport equipment between KDDI, KDDI
Research and MobiCom as a significant step towards the introduction of open and
disaggregated network solutions. The DCSG and TIP's open optical and packet
transport solutions will help to provide the capacity within the transport
network required to make 5G a success in satisfying the requirements of
consumer, operators and enterprises."
KDDI, KDDI Research, and MobiCom will accelerate innovations of telecom industry
by sharing the outcomes of the trial with TIP community, which will ultimately
contribute to practical improvement of open and disaggregated equipment and
growth of the open ecosystem.
