Our application envisages 3 different methods to use cellular phones for accessing these location-based prayer timings:
1. Stand-alone Solution, whereby handset is equipped with location-determining-element like GPS, etc. The algorithm, to calculate Azaan-timings, also resides on the handset, and announcement /notification is made as per user preferences. This application is ready for Windows Mobile & J2ME while Symbian C++ version may also be prepared with minimal efforts. However, this application addresses a small market segment I-e. â€?Muslim worshipers who have GPS-capable handsetsâ€?
3. Subscribed Notification Service, whereby Web-based Application server keeps track of subscriber’s Cell-ID, and PUSHes Azaan-info to subscriber’s handset, at local prayer-times. This traffic uses Push-Proxy-Gateway, and the handset is required to be MIDP 2.0 compatible to support push-mechanism. Some architectural work has been done for this embodiment but no code has been written because it requires full integration with operatorâ€™s network. Still, this embodiment is expected to be most successful as it realizes the full potential of the innovation. Here the market segment is significant in size: â€?Muslim worshipper who have cellphonesâ€?. This embodiment is illustrated in the next slide.
