DESIGN AND
IMPLEMENTATION OF THE PAY-AS-YOU-GO-CALL BILLING SYSTEM
ABSTRACT
It is obvious that
the trend in techniques today has gone beyond the ordinary to extraordinary
expect are working unrelenting to postulate new theory, disorder or manufacture
new technology to satisfy the human desires or need and to solve global problems
that is to say as time changes new development comes into place.
Today the use of
traditional or manual system of problem solving has left an excruciating pain,
struggle and downfall of many business organizations. Today almost ever
business activities can be carried out using automatic machines.
The automation of
these activities has contributed immensely to the comfortability of human
existence therefore via the desire and need to improve. The standard of living,
the computer has been introduced to the various field of endeavour which
includes the pay as-you – go call billing system thereby enhancing its
production and reordering its sales.
The motivation for
security, accuracy, stability, comfortability and satisfaction in the cellular
telecommunication system is to secure communication and data signal from
interception as well as to prevent telephone or communication fraud.
With the former
analog based cellular telephone system such as total access communication
system (TACS) and the advanced mobile phone system (AMPS). It is easier for
radio signal to intercept or interrupt telephones conversation with the
security agents.
Another security
consideration in cellular telecommunication system involves identification of
credentials such as electronic serial numbers (ESN), which is essential for
easy assessment deification and analysis.
ORGANIZATION OF WORK
This project is made
up of seven chapters, the first chapter is the introduction which statement of
the problems, purpose of study aims and objective and the project.
Chapter three
analyses the existing manual system and the present form of data processing.
Chapter four is the
project system design in much is outlined the various aspects of design.
Chapter five contains the method of system implementation and evaluation
chapter six covered the documentation of the system.
Chapter seven is the
recommendation and the conclusion.
In-order to
understand the system further, a few pages were keywords are defined have been
imported in chapter one for easy assimilation with more complicated equipment.
It is possible to receive the ESN and use it to commit cellular telephone fraud
by “cloning” another cellular phone and placing call with it. The procedure
where in the mobiles station (MS) registers its location with the system is
also vulnerable to interception and permits the subscriber’s location to be
monitored when a call is not in process.

INTRODUCTION
In response to a dear
market need for flexible recording services, business introduced
“pay-as-you-go” call recording. This specialist service ensures complete
control over you recorded calls remains with you, a bespoke call recorder is
implemented at your site, configured to your telephone system and network. Any
type of telephone can be captured, including VOLP. An agreed billing period is
settled with usage only charging price per recorded minute or seconds which
means no capital expenditure or rental/service charge.
Detailed usage
reports are provided which for outsourcers can be on a per-customer basis,
calls can be found easily from desktop PCS using a myriad of search criteria.
Such as data, time, duration agent name, client name, incoming telephone number
and more storage can be arranged for welfare period required even years.
The pay as-you-go
services ensures you maintain control of all calls, as calls are recorded and
stored at our own site system. Here you buy access time you want and pay before
making our call pay-as-you-go allows the subscriber to pay his or her monthly
phone call bills in advanced by loading recharge voyage or cards this access
time is purchased in various denomination on a card called “Alimony”
With Nitel
pay-as-you-go you re not tied to 9:12 month. Contract and don’t have to worry
about bills, just top-up-you talk time as you go, this system is very much
suitable for individuals who want access to telecommunications instantaneously.
It enables you to manage your own expenditure do so as to effectively meet your
communication needs.
This system has been
in existence in many organizations; but most cases is the manual or traditional
approach therefore an introduction of an automated machine or computer system
will adversely improve the system planning in the following ways:
i.
Flexibility
ii.
Reliability
iii.
Accuracy
iv.
Variability
v.
Timeless
vi.
Safe data storage
1.1
STATEMENT OF PROBLEMS
Today, with regard to
the current trend in technology, almost every aspiring organization had their
billing system computerized, organization such NITEL and NEPA has changed there
billing system which was formally manual to automatic, despite the changes, made
so far, they still encountered some irresistible and unavoidable problems such
as wrong billing, inaccurate timing and displacement of vital information.
Therefore in these
GSM pay-as-you-go billing system the design will first access the credit balance
before giving the customer or client access to the telecommunication networks.
It ensures accurate
reading and billing of time and cost either per minute or seconds; resulting to
a desirable satisfaction between both parties at the climate of the transaction.
1.2
PURPOSE OF STUDY
The purpose of the
work is to accurately observe the setback and drawback of the manual
techniques; analysis the likely cause of the problems and consequently device a
means of solving or eliminating the drawback through the introduction of the
computer system executing the basic clerical duties.
Computerizing the
pay-as-you-go call billing system makes it very easy to reach out to
prospective customers scattered all over the nation and creates an outstanding
and firm relationship between the organizations and her customer.
1.3
AIMS AND OBJECTIVES
