Siemens has integrated Phone.coms UP.Link server solution into Hutchison Telecoms mo-bile networks which enables Hutchison Telecom to offer mobile customers easy access to a broad variety of Hutchison Telecoms online information services and applications. The services can be accessed through mobile phones equipped with a WAP-browser.

The Wireless Application Protocol is an open, global specification that empowers mobile users with wireless devices to easily access and interact with online information and serv-ices. WAP enables wireless devices to quickly access Web sites specifically designed for mobile phones and terminals and optimizes the information displayed on the mobile phone display. Through WAP, the user cannot only access typical public information such as sports, news and email, but also can get protected access to corporate applications deliver-ing user-specific information over the mobile network. The user could check, for instance, the cost, length, destination and time of call. Furthermore, WAP enables a multitude of other services, from games to advanced online Personalized Information Management (PIM) func-tionality such as constantly updated calendar and address book services, which can be eas-ily accessed through a mobile phone. WAP based services are also an ideal way to open and combine the various possibilities of IN (Intelligent Network) based mobile services.

Besides the typical circuit-switched data communication available today on mobile networks, GPRS (General Packet Radio System) represents the future packet data service, which will enhance WAP-based services. GPRS is expected to be commercially available in the third quarter of next year by Hutchison Telecom.
