This document discusses the potential of microservices architecture in the telecom industry. It begins by defining microservices and their design principles, including organizing around business capabilities, decentralized logic, and infrastructure automation. The document outlines advantages like agility, efficiency, resiliency, and increased revenue. It provides examples of using microservices in telecom, such as for virtual radio access networks to improve 5G networks, Optus' use of mobile edge computing for call transcription, and new open digital architectures for operational support systems.

3. WHAT IS
MICROSERVICES?
• Microservices are an architectural
approach to building systems.
• Components are distributed and loosely
coupled.

7. MICROSERVICES
ADVANTAGES
• Agility – by breaking down near-atomic
level functions, development take only
weeks.
• Efficiency – Users report substantial cost
savings by 50 percent.
• Resiliency – no single point of failure.
Scale seamlessly on demand.
• Revenue – Increase user retention and
user engagement.

9. MICROSERVICES
IN TELECOM.
• 5G Opportunities x Challenges
 https://martinfowler.com/articles/microservices.html
Opportunities
100-400Mbps speed
Low latency ~8ms
Virtual Reality Apps
IoT Apps
Challenges
High freq. (>24GHz)
Cell covers ~ 300m
Large #of cells

10. VIRTUAL RADIO
ACCESS
NETWORK
(VRAN)
• Virtualizing the network central unit
• Simple, mass deployment of 5G small cells
• Enable intelligence network management
operations
better spectrum utilization
higher throughput
faster response time
lower cost of operation
• Support newer breed of low-latency
services defined in mobile edge computing
• Etisalat UAE launched vRAN on Jan-2020

12. OPTUS USE CASE
MOBILE EDGE
COMPUTING
• Online Call Transcription and Translation
• Realtime handle of RTP connection,
• Avoid latency,
• Deploy virtualized media function on call path

OPTUS second largest telecom
company in Australia

13. MOBILE EDGE
COMPUTING
• Using Microservices architecture
• Pushing content, apps and network
resources closer to the user.
• Innovative design to support the new
breed of apps
 IoT,
 Autonomous driving,
Virtual reality.

14. OPEN DIGITAL
ARCHITECTURE
(ODA)
• New vision for operational and business
support systems (OSS/BSS)
• 50+ REST-based Open APIs has been
collaboratively developed to be used in a
range of scenarios
• Signed by 54 of the world’s leading CSPs
and technology participants
