 Your 5G opportunity
5G is your opportunity to become the company
you were meant to be. But how do you serve
everyone and everything, while maximizing returns?
The answer lies in rethinking the core.

Our 5G Core frees the innovation within your network,

so you can automate, customize and monetize your
core with total confidence.

The architectural design is inherently cloud-native,

secure and resilient. Network functions are deployed
and scaled, rapidly and wherever required.
The software is continuously optimized for
performance, efficiency and sustainability.

We proudly celebrate that CSPs and Enterprises all

over the world are working with us and our partners
to transform business, industry and society.

 5G Core: make it real
5G’s marketplace needs a core that is cloud-native and uses a service-based
architecture (SBA). The new technology drives a remarkable shift in the core’s
networking and operations. This is necessary to deliver high-performance,
low-latency, ultra-reliable service, which are critical to winning in new markets
including Industry 4.0, scaling Internet of Things (IoT), and blending physical and
virtual experiences.

CSPs & Enterprises use our 5G Core to:

Profit with services such as network slicing, which enables efficient sharing of

network resources while ensuring custom service level agreements for various
applications and services.

Simplify with a core geared for extreme automation, efficient operations and

sustainability. Prevent errors from affecting productivity. Quickly scale larger and
smaller by matching resources and demand.

Open the core, so that it works across multi-cloud, serves any access, and is
deployable on the edge cloud. CSPs and Enterprises can securely guide the
creation of their own new services using the core’s open APIs.

Be confident that the core delivers financial, operational and strategic results,
while ensuring the evolution from 4G to 5G is efficient, effective and secure.
