Tokyo, March 6, 2025 – NEC Corporation (NEC; TSE: 6701) has improved the
performance-to-power ratio of 5G mobile core systems (5GC) by more than 6
times, as well as floor space density by 10 times. This was accomplished
using Intel Xeon 6 processors with E-Cores under a traffic load and model
based on actual commercial traffic patterns.
Background:
As mobile communications continue to evolve from 5G to 6G, there is a
continuing need to handle the ever-increasing volume of mobile traffic. To
meet this demand, computing resources in data centers keep increasing,
posing challenges on how to handle growing power consumption and floor
space. Customers are also demanding improvements in performance per power
consumption and floor space density of 5GC, helping to reduce greenhouse
gases and improve cost performance.
Working jointly with Intel, NEC has achieved a significant improvement in
performance per watt and floor space density, verified using the session
management function (SMF), which is a core function of NEC’s 5GC,
onboarded on Intel Xeon 6 processors with E-Cores.
Benefits of NEC’s 5GC:
NEC’s 5GC has advanced parallel computing technology that makes use of
multiple CPU cores and features flexible scaling. This enables NEC’s 5GC
to make the most of the capabilities of Intel Xeon 6 processors, resulting
in significant improvements in performance.
Additionally, NEC’s 5GC is compatible with a variety of environments,
including on-premises used in this verification, as well as public cloud,
and can provide the benefits of high performance in any environment.
Moving forward, NEC will continue to improve the performance of mobile
core systems, aiming to advance networks towards the Beyond 5G/6G era. NEC
is committed to contributing to the digital transformation (DX) of
telecommunications carriers, improving the end user experience, and
developing the mobile network market.
