1. Telecommunication Evolution
Joint African and ITU SNO Conference Zanzibar, Tanzania
22nd – 26th September 2014
Presented by: Francis Dlamini (General Manager Swazi Telecom, SPTC)
23rd September 2014

2. Presentation outline Telecommunications Layers The OSI model layers
Drivers of Evolution
Advent of M2M communications
Significance of NOC, SOC, CEM
Key Issues and Challenges

3. Telecoms Layers Devices layer Last yard/mile layer Access Layer
Transport Layer
Session Control Layer
Services Layer
Network Management Layer
Management Information Layer

4. The OSI reference model
All network elements operate in the layers above
Need for all technical staff to master OSI

5. Drivers of Evolution Bandwidth hungry OTT services
Decrease in smart devices market prices, thus
increased adoption by market
Adoption of Machine-to-Machine communications
Invent of the connected/smart home and office
New innovations by system integrators and
researchers
Drive to reduce OPEX and increase revenues
by telcos
Drive to align services with the consumer industry
needs

6. Advent of M2M communications

7. Advent of M2M communications
M2M is about communication between devices,
objects, things
Bandwidth usage by M2M systems is always 100%
any the time of the day
Techno-economic forecasts indicate that in the
coming years M2M communication will become
massive, connecting tens of billions devices
All industries are waiting for such M2M systems
to realize smart operations
M2M communications is the common language for
all devices to communicate

8. Significance of NOCs

9. Significance of NOCs The NOC centres are a key tool for the
operator to manage service and customer experience
To avoid counting the wrong sheep and to avoid sleepless nights for operators’ management
Drastically reduce OPEX, thus increase in revenues
To better manage threats and opportunities by OTT players
To keep consumer experience, and knowledge base
Keep fault management and resolution experience

10. Key Issues for Network Operators
Description
Action
Backward compatibility with existing systems and services
Take an inventory of existing network technologies from operators (regional) before developing new technologies
Interworking between the old and new technologies to complement each other
There must be a standard to ensure service migration from the old technology to the new technology
How do we synchronize technology rollout among operators taking into account inter-operator connectivity issues
Operators to discuss with each other to achieve good inter-operator connectivity to better service in the local market and customers
Operator and vendor sign-off of product roadmaps based on operators strategic plan and technology roadmap
Ensure that the Operator has a clear evolution plan to match market and business development
Consider the involvement of operators in the development of new products
Vendors should share the latest technology and product road map by quarterly with each operator
Multi-vendor integration
Vendors should have good inter-operation designed solutions to guarantee the integration
Network simulation and verification before implementation
The operator and vendor should have good network planning before deploying the network to guarantee the performance of the network
