Cellular Phone Billing System Using WAP

Abstract

Cellular systems Subscribers experience a problem in receiving and paying bills on time. Many solutions were developed to overcome this problem. One of them was to get and pay the bills online, but this solution demands that the Subscriber should have a desktop computer with an Internet access and of course armed with the necessary knowledge of using it. In addit ion to that, the Subscriber should be right there on his desk This system comes into sight to take the advantage of the WAP 1 service available in the cellular phones to enable the subscriber to view their bills and provide them with payment procedures as well as to view a variety of announcement and advert isements any time and anywhere; all what is needed is WAP service enabled cellular phone. The System consists of two main parts: One part is for the System Administrator with the purpose of managing the system. The other one is the WAP system for the Subscriber. The first phase is the system requirements definit ion and locating the system specification, the outcome of this phase is that the system should provide the Subscribers with the abilit y to get their bills and providing payment procedures, also to view their announcements, based on their service t ype, but previously authent icated. In addit ion, cellular provider can make use of it by advert ise on this WAP service. The system has been designed using UML 2 2.0. This methodology was selected to serve the Object Oriented Implementation of the system; in this phase classes and many UML diagrams are developed. Based on this design an Object Oriented programming language (visual C#) is used for writing the code, Microsoft Visual Studio 2005 has been used as a developing environment. Finally all required tests were performed on the system. And a special t ype of testing was also performed using the mobile emulators to ensure that the system work across the Varit y of cellular phones brands and mobile generations.
