•
historical operator since 1930’s
established in 1992 as state-own company
from 1992 havy investments due to credits from World Bank
pressure from customers
Internet impact
successive market deregulation
still 1,5 M of subscribers of analog exchanges
possible problems with existing software systems upgrades
TP Capital Group:
• TP ( 10 M of subscribers)
• PTK Centertel - mobile operator (3 M of subscribers)
• TP Internet - internet provider

Next Generation Network
What we expect from NGN technology:
• simplify network architecture
- network layers
- protocols
• obtain manufacturer independence
- standard API
- independent layer development
• easy scalability
• convenient creation of new services
• flexible interconnection with competitors
- possible source of profit
• integration with other information technologies
- TV, radio, knowledge databases
- computer networks
• unified multi-service network

NGN - development level
State of the art.:
• huge literature
• evolution of concept
- manufacturers, operators, customers
• standardisation still on going
• no complex implementations
- TDM still cheaper
- traditional voice makes profit
- new services should balance cheep packet voice
• successive step in telecommunication
• different opinions from companies
- maintenance costs of existing infrastructure
- implamentation costs
- no ‘killer application’
• doubts about the return on investment

NGN implementation
NGN implementation seems to be the necessary step in
developing of telecommunication infrastructure, but
during the discussions about the concept we realised
potential threats:
28/03/2016
•
organisational aspects
•
economical aspects
•
technical aspects
6
NGN implementation
Organisational aspects
•
actual distributed TP organisation dependent on technologies
should be redefined
- coexistence of new and old technologies can create
new challenges
- fast technology development requires dynamic and
flexible organisations

NGN implementation
Economical aspects
28/03/2016
•
CAPEX and OPEX balance to keep growth of profit
•
diversified service level agreement
8
NGN implementation
Technical aspects
28/03/2016
•
integration with existing technology forms hybrid
architecture
•
new tasks to manage of hybrid network structure and
assure security
•
interoperability between systems
•
plan of simplification of the network can cause
complication first
•
possibility to define QoS level due to customer’s
requirements and opportunities

TP start to NGN
CBR (TP S.A. R&D) started NGN project to check the real
possibilities (in cooperation with France Telecom R&D):
28/03/2016
•
define main assumptions
•
NGN scenarios
•
request for information
•
tests and selection
11
TP start to NGN
We are going to check the real possibilities:
• define main assumptions
•
NGN scenarios
•
request for information
•
tests and selection
28/03/2016
- minimize investment in non NGN
technology
- progressive consolidation into unified
multi-service packet network
- avoid to disturb existing functionality
management
services
Intelligent Network
- customers shouldn’t be forced to
change existed equipment
- reserve necessary period for migration
to confirm stability and reliability of the
solution
12
TP start to NGN
We are going to check the real possibilities:
•
define main assumptions
• NGN scenarios
•
request for information
•
tests and selection
- transit: interconnecting narrowband
switches over packet core network
- access: voice only services for areas
served by analog exchanges
- access: voice and data services with
advantages of xDSL technology
- access: integrated access merging
voice and data services in a single
infrastructure
- demand models: theoretical network
models for getting information about
prices, to get ability to compare solutions
on economical level
28/03/2016
13
TP start to NGN
We are going to check the real possibilities:
define main assumptions
•
NGN scenarios
• request for information
•
tests and selection
- request for information to 14 companies
- evaluation criteria
We are here now !
•
- methodology of comparison of
answers:
1st step: subdomain analysis - referring
to certain equipment (VAG, TCS ...)
2nd step: domain analysis - referring to
scenarios, services, management,
economical analysis, migration strategy
3rd step: solutions rating
- analysis of answers
- classification of the solutions
- ranking of companies

TP start to NGN
We are going to check the real possibilities:
•
define main assumptions
•
NGN scenarios
•
request for information
• tests and selection
28/03/2016
- evaluation lab tests (preliminary)
- working out of Operator’s Technical
Requirements for NGN
- selection of NGN suppliers
- validation lab test (compatibility with
Operator’s Technical Requirements)
- integration lab tests
- implementation support
15
TP view on NGN
Summarising our work we want to balance ...
... technical approach ...
•
•
•
•
... functional approach ...
•
•
•
•
•
the base of new technology
equipment oriented architecture
forced by manufacturers
new equipment - source of costs
gives meaning to new technology
functional architecture
customer/operator needs oriented
new services - source of profit
lack of ‘killer application’ concept
?
... to answer the main question To NGN or not to NGN?
