INTRODUCTION
The utmost speed at which the
Universe is being turned into a global world is attributed to the sophisticated
in the development of the telecommunication industry. These radical changes
have been made possible by the invention of digital technology in electronics
and telecommunication analogue. This means that the signal been handled,
processed or transmitted are presented by voltages whose amplitude and
frequency vary. Continuously with time.
Consequently, in the telephone
system, the transmitted signals are direct representation of the speech
waveforms. This did not sound waves in the system.
This project is aimed at developing
a system that will help in the billing section of Vmobile to enable it to serve
its customer effectively. Also, able to bill them accurately and also give the
customers detail of how they are been billed either in PMB or PSB.
The PMB is the old order by which
the network operator bills you for a minute when your calls lasted for a few
seconds, these rounds up your call cost to the next minute white the PSB is the
current order that gives subscribers the opportunity to pay for the exact call
duration.
Today, most Vmobile products like
Vecgo, Vstep, Vbusinss and Bumpa come with the PsB Option. Infact, Veego, Vstep
and BUMPa now have PsB option as default.
Although the billing processing
system has been in existence in many organizations though in a traditional
approach and in anticipation.
Introducing the computer system will
greatly improve materials requirement planning in the following aspects:
1.
Reliability
2.
Variability
3.
Accuracy
4.
Appropriate storage of data
5.
Timeliness
1.1
STATEMENT OF THE PROBLEM
The quest for a more sophisticated
and effective system that can handle the GSM bills of the customers in
telecommunication companies has led the researcher to the designing and
development of a software to handle the GSM billing system of customers in
Vmobile Nigeria Plc.
In our society today, if we take a
close look at NEPA, NITEL etc. we will discover their billing systems that was
formally manual, has been computerized, because most times, many telephone
subscribers do complain of excessive billing and this has often be traced to
the carelessness or otherwise on the part of the staff that prepare the bills
and yet still collect their revenue. In these GSM Billing system the design
will look at your balance before allowing the customers to make call. The calls
is been checked by both parties and at the end both of them are been certified
of every transaction.
1.2 PURPOSE
OF STUDY
The purpose which this project work
is carried out is to identify and eliminate all the drawback that are
encountered in the manual techniques through the introduction of computers to
carry out basic clerical duties. By computerizing call billing system, this
operation will become easy to reach prospective customers scattered all over
the nation.
Another purpose of this project work
is to ensure accuracy in the daily operations or activities. Again, file and
other documents are protected from non – authorized user and from environment
hazards.
1.3 AIMS AND
OBJECTIVES
The aim of the researcher is to set
an all round criteria for GSM operators especially Vmobile Nigeria Plc. If the
new system is well utilized, the great organisation must surely achieve greater
heights.
The objective of the study is
critically looked into existing billing system with a view of locating any loop
hold and subsequently design a system that integrate the existing one and which
should be suitable for use in the Vmobile Nigeria Plc. The new system will be
able to take care of the most of the problem experienced with the system
already in place. Also this project will evaluate the perceived notion of this
type of GSM operator. The researcher intends to design and stimulate a software
that will depict the billing system as regards Vmobile Nigeria Plc.
1.4 SCOPE OF
STUDY
The system is intended to take care
of every aspect that relates to the control and operation of the GSM billing
system for Vmobile Nigeria Plc. The final information provided will be used for
improved customers services, financial control and operation. This reports so
far should be generated at a regular and continuous manner as not to mis-lead
the company and the subscribers.
The report will delve into the
existing system of Vmobile with the view of finding out their usefulness and
short comings and this should be made to find a suitable approach to
accomplished the desired goal.
1.5
LIMITATION
There are number of factors which
complied the researcher to limit her studies in Vmobile Nigeria Plc amidst
numerous communication companies.
These factors include the following:
(a) Lack of
finance for transportation to the case study and library.
(b)
Unwillingness of the staff in Vmobile Nigeria Plc to give the researcher enough
information.
(c)
Lack of time due to the short semester and moreover other m examination.
(d) Lack of
sophisticated telecommunication books.
Further more, the same constraints
made for the enhancement of the intended new system.
1.6
ASSUMPTION
The researcher made the following
assumptions:-
(a) She
assume that the staff in the billing or account department of Vmobile Nigeria
Plc for which the program is basically designed are computer literate and
therefore could conveniently operate the system when implemented.
(b) She
assumes that the management will give the new system the support and
supervision and effectively.
(c)
Finally, the assumption is made that at the cumber some task of retrieving and
updating records in packs of books would be eliminate and easy process of
retrieving, updating and searching for the bills as it affects Vmobile Nigeria
Plc would have been adequately taken are of.
