5G: A Transformation Journey towards smart cloud choice or necessity

Introduction:

The Fifth Generation of Mobile Telephony, or 5G, or 5GS, is pushing out further, transforming connectivity which enables faster data transfer speeds.  Worldwide, operators are adopting 5G to support wide range of traditional use cases with better customer experience as well as for Machine-to-Machine communication and also to be use by all industry sectors, for time critical applications such as autonomous driving. 5G uses a set of dedicated technologies, such as “Network Function Virtualization” and “Slicing” to increase the modularity, “EDGE computing” for faster response time, Non-Terrestrial Networks (NTN) / Satellite Communications for ubiquitous coverage, etc.  The blog provides the details viewpoint of 5G and its association with cloud – what to choose and why as majority of 5G deployments will happen in telco cloud.

What problem 5G is trying to Solve: Need for more speed or something else it is trying to solve?

  • To support Exponential growth of connected device.
  • To support various use cases of connected device

5G Use cases:

Well, the answer is logical slice of network and customized based on industry requirement.

Following are the future common use cases for 5G

  1. Railway slice – you will love to travel more because you get good network than your home – just kidding J
  2. Car slice – car manufacture makes sure when you switch on your ignition – it will not only provide internet to you, but it also makes sure car health check is continuously get monitored even before calling manufacture for any help – they are with you.

These are the possibilities, now the question is who is benefited, is it the industry that we are associated or communication service provider or equipment vendor/service provider or cloud provider or just us?

Now, let’s understand the capability viewpoint of different stockholder in 5G.

Capability-Viewpoint analysis of Telcom-CSP, equipment vendor, service Integrator and cloud provider:

Existing core N/W modernization and move B/OSS stack to SBA, might abstract legacy based N/W SDH/PDH with available options Key driver to move existing B/OSS stack to Cloud native B/OSSCreate more edge closer to Telecom CSP/ enterprise customer to support private/public 5G deployment.

 

Telco process and function overview

We have seen that network layer consists of NE (network element) and EMS (element management system) can’t scale, it requires physical equipment to be procured and placed in a place, so more equipment/its capacity large number of customer base csp can operate – hence the scale can be achieved only vertically.

Hence horizontal scale would always be a challenging until we have look for something which can solve the problem of physical hardware/proprietary software and the answer is virtualization, isn’t it … now special physical hardware replaces with commodity hardware to run in scale.

It opens the door for equipment vendor to make the necessary changes and opportunity for cloud provide/ hyperscale.

5G Market as we analysis

Conclusion:

We hope, the introductory series provides the overview of the following

  • Viewpoint analysis of 5G different stake holder but also raise question – who is for 5G
  • 5G and Cloud and its association and it also provides that virtualization is the only key enabler for make 5G successful
  • 5G market analysis
  • It also introduces lot of question(s) – which cloud to choose, is it public cloud or private cloud or hybrid cloud?
  • Does O/BSS function require API and thus microservice
  • Is microservice the default option always
  • What is the best performance if all function runs on commodity hardware.

We will analysis all the question(s) in the coming blog(s) and request you to provide feedback the question you want us to cover in next blogs.
