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

2 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. Smart cities Smart homes Smart health Smart workplace

3 This allows organizations to Scale Manage Secure Analyze Monetize billions of transactions and zettabytes of data, created by an ever-increasing number of connected devices and machines.

The introduction of innovative and disruptive networking paradigms,

4 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.

5 5G Introduces Service-based architecture IT-centric cloud services Personalized network slices that meet the requirements of industry-vertical applications

6 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.

7 The True Business Value of a Service-Based Architecture (SBA) SBAs provide a set of loosely coupled services that empower CSPs to be more agile and enable rapid service delivery.

8 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.

9 The Journey to 5G There are many different deployment options when migrating to a new 5G network Deploying Option 3x nonstandalone architecture Incrementally monetizing 5G services Evolving from Option 3x nonstandalone architecture

10 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.

11 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

12 Other Deployment Options EPC 5GC Standalone Architecture LTE EPC Option #1: SA LTE under EPC NR 5GC Option #2: SA NR under 5GC LTE 5GC Option #5: SA LTE under 5GC Non-Standalone Architecture LTE NR EPC NR LTE 5GC LTE NR 5GC Option #3: NSA LTE and NR under EPC Option #4: NSA NR and LTE under 5GC Option #7: NSA LTE and NR under 5GC

13 Deployment Considerations There are several options available for evolving to 5G. CSPs must consider the practicality of each option across different variables: Fulfilling the requirements of intended initial use cases The interoperability and interworking of these options with the rest of their network

To make the most of service-based architecture To leverage flexible slice

14 5G NGC Is Essential No matter the deployment path you choose, a new 5G core is key. Why? To make the most of service-based architecture To leverage flexible slice selection To take advantage of slice procurement and lifecycle management To separate control and the user plane through native support

15 4G to 5G Interworking 4G 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

16 The Right 5G Partner will understand the challenges associated with evolving communications networks. Leveraging 4G networks Evolving to the 5G NGC It s crucial to select a partner that has deep IT and cloud expertise, helping simplify the network and provide an open, cloud-native architecture.
