The Evolution from 4G to 5GSmart steps for a successful network migration.

5G shouldn’t be seen simply as the next generation of mobile communications.

It’s a smart ecosystem that’s ready to ignite new innovations and highly customized services.

This allows organizations to…

…billions of transactions and zettabytes of data, created by an ever-increasing number of connected devices and machines.

But evolving to a new 5G core is different from previous mobile network generations.

The introduction of innovative and disruptive networking paradigms, which are often unfamiliar, means the traditional one-size-fits-all approach to network infrastructure is no longer enough.

Service-based architecture

IT-centric cloud services

Personalized network slices that meet the requirements of industry-vertical applications

5G Introduces…

The Result?

Communications service providers (CSPs) are able to launch and evolve custom-fit network slices faster than ever, while lowering capital expenditure and operating costs.

This opens the door to new, customized business services that generate greater revenue.

SBAs provide a set of loosely coupled services that empower CSPs to be more agile and enable rapid service delivery.

The True Business Value of a Service-Based Architecture (SBA)

The Potential of Network Slicing

Enables the 5G network to deliver tailored connectivity services that meet the requirements of any given application, user, device, or context by providing dedicated and customized end-to-end logical networks.

Network slicing is a highly dynamic process that involves defining, instantiating, selecting, scaling, and de-instantiating slices.

There are many different deployment options when migrating to a new 5G network.

Deploying Option 3x Nonstandalone Architecture

By deploying Option 3x nonstandalone architecture, CSPs can adopt the 5G New Radio (NR) alongside a 4G LTE radio and Evolved Packet Core (EPC).

This helps CSPs get started with 5G by leveraging their existing EPC and accelerates their time to market for new 5G services.

Incrementally Monetizing 5G Services

It has become increasingly complex, costly, and time-consuming to deploy new, or modify existing, services on the 4G EPC network.

Since Option 3x may be around for longer than anticipated, CSPs should look to monetize their existing investments by offering new 5G services…

• Offloading their EPC in favor of separate overlay cores and dedicated core networks that introduce network slicing into their 4G core

• Leveraging dedicated cores to offer 5G services and later evolve to 5G network slices

Deployment Considerations

Fulfilling the requirements of intended initial use cases

The interoperability and interworking of these options with the rest of their network

There are several options available for evolving to 5G. CSPs must consider the practicality of each option across different variables:

4G to 5G Interworking4G LTE and the 5G networks will continue to interwork for a number of years.

This is why it’s essential to…

• Support a seamless handover between the EPC and 5G core networks

• Maintain service continuity

• Leverage the full potential of an agile and rapid 5G architecture

The Right 5G Partner…
