In this paper, a simple and innovative network based mobile information system technique is introduced, that provides extensive flexibility at the user end. This paper discusses the methodology adopted for the design and simulation of location based friend finder and location based web tracking services. Both these services are integrated with the real-time billing system. An advance technology of using spatial triggers is introduced that results in a cost-effective solution for mobile companies.
