KDDI, KDDI
Research, MobiCom, and the Telecom Infra Project (TIP), are pleased to announce
the launch of 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
cases, etc.
Configuration of the
interoperability trial among DCSG, transport, and core networks
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 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.
Today, 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.
