This work gives definition of a methodological approach to build information
system of telecommunication company based on models, through consolidation of
general approaches of IS development and a ...specific initiative within
telecommunication area: - MDA (Model Driven Architecture), an approach to
software development that was set as a standard and promoted by OMG (Object
Management Group). - EA (Enterprise Architecture), an approach to
simultaneous development of Business and IT Architecture of a company. TOGAF
(The Open Group Architectural Framework) is the most common and best known
architecture framework and method for enterprise architecture development. -
NGOSS (New Generation Operations Systems and Software), a program being
developed by Telemanagement Forum that represents a framework for development
and implementation of „Operation and Business Support Systems – OSS/BSS”
within telecommunication industry. - SPL (Software Product Line), a
development of IS over Software Product Lines, represents a modern approach
to automation of domain-specific model-driven software development, where a
software product family, and not a single software product, is developed
through domain engineering. The methodological approach is based on a
software product line specific to telecommunication domain which is based on
NGOSS frameworks and models and which allows efficient building of
Telecommunication Company IS through the following three distinct processes:
- General domain engineering for telecommunication domain, - Domain
engineering for telecommunication domain type of service, - Application
engineering. In order to define a methodological framework for development of
model-driven telecom operator IS it is necessary to have a good insight into
the following dimensions of complexity in telecommunication domains:
Functional Domains, Areas of Integrated Processes, Types of Telecommunication
Services, IS Development Life-Cycles Phases, Specific Telecom Operators IS is
being developed for. Afterwards, it is necessary to define both mutual
relationships and dimension-shifting sequences. The basic initial scheme that
gives classification of telecommunication domain by sub-domains and
horizontal and vertical dependencies between sub-domains was defined based on
eTOM and SID NGOSS Framework. The basic mechanism, named “Multi-level Staged
Configuration”, was defined as technique which overcomes the complexity of
telecommunication domain and works as a transition from one sub-domain to
another. When such mechanism is applied to the basic initial classification
scheme the result is a system for multi-level staged configuration of
telecommunication domain. After that, it is possible to define a framework
for telecommunication domain software product line that, through domain and
application engineering, encompasses all previously mentioned dimensions of
domain complexity. Due to multidimensional complexity of telecommunication
domain, this approach implies specific domain engineering which consists of
two levels: General domain engineering for telecommunication domain and
Domain engineering for type of service. The General domain engineering for
telecommunication domain; One of important steps of this domain process is
defining system for Horizontal Multi-level Staged Configuration (HMLSC) HMLSC
system is responsible for controlled and comprehensive definition of all
initial Features Models by functional areas of telecommunication domain. The
System is implemented through four HMLSC schemes. Within a functional area,
models are horizontally dependent on each other and are constructed in
accordance with defined dependencies between sub-domains. Besides Feature
Models by functional areas, all necessary UML model patterns are also
defined: Data Model Templates, Behavior Templates (applications and
processes), etc. Another important step of General domain engineering for
telecommunication domain is defining system for Vertical Multi-level Staged
Configuration (VMLSC). This system is implemented through six configuration
schemes. A main result of Vertical Multi-level Staged Configuration execution
is implementation of vertical processes development through multi-level
staged transformation of Feature Model, where the result (configuration) from
the previous level represents input parameters for model construction on a
lower level. The next important step is Defining system for Model Generation.
Features Models represent well common and different features of product
families. However, feature models do not serve their own purpose. They
represent a guideline for construction of domain-specific data or behavior
models. It means that feature models should be mapped into other models to
transmit to them the necessary semantics. Mapping of MC into other models is
performed through model generation schemes. Domain engineering for
telecommunication domain type of service. In this section of Software Product
Line (SPL) for telecommunication domain, the configuration schemes for
Horizontal Multi-level Staged Configuration (HMLSC), defined in General
Domain engineering, are further elaborated. These schemes normally represent
rules and a path for defining models for type of service. Through use of
these schemes, all initial Feature Models for IPTV service are defined by
functional areas of telecommunication domain. In the second section, the
schemes elaborated in General Domain Engineering for telecommunication domain
that form the System for Vertical Multi-level Staged Configuration (VMLSC)
are further elaborated. These schemes normally represent rules and a path for
defining End-to-End Processes for type of service. Through use of these
schemes, Feature Models are mutually annotated and a procedure of vertical
processes development for IPTV service is defined. In the section of this
domain process, are also defined schemes for automated configuration and
generation of UML models of class diagrams and activity diagrams for IPTV
service, based on UML model templates for IPTV and configurations of Feature
Models. Application engineering for telecommunication domain allows
specification and generation of a specific operator’s IS. Simultaneously,
this part, as well as the entire methodological approach, is illustrated
through step-wise tailoring and generation of a specific IS for a specific
IPTV service operator. Configuration of a specific operator’s request for IS
(Including IS) is performed first. After that, the IS is being tailored in
detail using Vertical Multi-level Staged Configuration. During this process,
generation of a specific telecom operator’s IS models is performed.
Model-driven methodological approach to development of telecommunication
company IS contributes to the solution of the following problems of IS
development: - Solution of IT and Business Alignment, a problem that arises
from differences in abstraction levels of Business and IT concepts. - Finding
the way to overcome Multidimensional complexities of telecommunication
domain. - Solution of the problem of IS development caused by Business
Dynamism, because, besides being complex, Business is also highly dynamical
due to constant and fast switches of technologies, user requests for new
services, market competition, etc. - Allowing mass customization of services
that remained unsolved by the existing methodological approaches, due to
uncompleted solution of software reuse problem. - Supplements to general EA
approaches and NGOSS domain EA with detailed models of telecommunication
domain that are functional with specific telecom operators, through use of
the existing ISs. - Allowing more efficient model transformation that
represents one of the major general problems in MDA approach. This work
closes with a review and a comparative overview of advantages and
disadvantages of the existing approaches and methods used in the thesis and
discuss the advantages brought by the approach the thesis sets forth. The
automation of presented methodological approach brings more efficient IS
development; especially bearing in mind the great potential of this approach
for becoming the general methodology of IS development.
