Enhancing service portability in upcoming 3G UMTS networks & security aspects

Compared to other wired networks, complexity in the 3G UMTS is due its interactions with different entities. Within the UMTS, services have to deal with a great number of different QoS, small user display, variant bandwidth and small battery power. Most of the services are generally bind to the particular systems or APIs. In this article, we look at the evolution of different technologies on which such service are build and apply the Web services framework to achieve the portability of the such services We take the example scenario and build the Web services model which can be implemented and deployed in the UMTS network.
