Abstract:
The principle behind Intelligent Networks (IN) is the separation of call and bearer
control from service control. This enables the rapid introduction of new services,
features and the ability to offer integrated service packages thereby reducing the
reliance on switch manufacturers for the provision of new services.
Global System for Mobile communications (GSM) is the accepted standard for
mobile communications not only in Europe, but world wide. GSM is also one of
the first networks with a standardised modularised approach to its architecture.
This thesis presents an architecture to integrate GSM and IN networks enabling
the provision of GSM mobility services from an IN platform. The approach is to
move mobility provision and management functions within a GSM network to an
IN platform, so providing mobility as an IN service rather than a GSM specific
service.
This proposal will enable the rapid creation of mobility based value added
services. Furthermore the proposed IN - GSM integration scenario can be seen
as an evolutionary step towards third generation mobile system UMTS.
The approach taken is to transform existing GSM mobility procedures such that
they can fit the IN Service Independent Building blocks (SIB) architecture,
thereby coexisting with IN SIBs on a Service Control Point. The GSM switching
and radio access network is retained to enable the maximum reuse of the
existing system.
The proposed project presents results from simulation studies carried out to
compare the performance of the proposed architecture against the GSM network.
Signalling protocol based simulations models were developed on VC# and
MATLAB for both the proposed architecture. The GSM simulation model was
analyzed based on mathematical principles and different KPIs (Key Performance
Indicators) were monitored and evaluated. Finally the results were justified by
mathematical implication and reasoning.
