ABSTRACT
Mobile communications, Internet connectivity, and multimedia technologies are progressively merging in a single paradigm of personal communications. Mobile communications originate from the increasing need of users to have information
available “anytime, anywhere.” Internet connectivity puts a huge quantity of information resources at users’ disposal, including services such as searching, browsing, e-mail, and E-commerce. Multimedia technologies are emerging as users want to have more information in audio/visual form rather than in textual form.
