Architecture for Wireless Application Protocol Published on the World Wide Web

-One broad, and global solution for existing and future Value Added Services in wireless networks

Ericsson, Motorola, Nokia and Unwired Planet (now Phone.com) (now Phone.com) introduced today the architecture of the Wireless Application Protocol for public review and comments on the World Wide Web. The new information forum for Wireless Application Protocol can be found at http://www.wapforum.org. This announcement follows the initiative the four industry partners made on June 26 of this year.

The Wireless Application Protocol is currently at the architecture phase. The protocol will include specifications for transport and session layers as well as security features. Over and above these network layers, the protocol will define an application environment including a microbrowser, scripting, telephony value-added services and content formats. The Wireless Application Protocol will be scaleable so applications are able to make the best use of available display and network data transport capabilities across a broad range of terminal types. Services can be created from single-line text displays in standard digital mobile phones to highly sophisticated smart phone displays.

The specification will be available on the new web site that also contains other essential information, such as the future development of the specification. The Wireless Application Protocol web site is also a forum for other industry partners to join in to further develop and provide feedback on the protocol.

The purpose of the Wireless Application Protocol is to provide operators, infrastructure and terminal manufacturers, and content developers a common environment that will enable development of value-added services for mobile phones. The four founding members aim to create, together with other industry partners, a global wireless service specification to be adopted by appropriate standards bodies and will be independent of the network infrastructure system in place. All the applications of the protocol will be scaleable regardless of transport options and device types.

The Wireless Application Protocol is targeted to bring advanced services and Internet content to digital cellular phones and terminals. A common standard means the potential for realizing economies of scale, encouraging cellular phone manufacturers to invest in developing compatible products, and cellular network carriers to develop new differentiated service offerings as a way attracting new subscribers. Consumers benefit through more and varied choice in advanced mobile communications applications and services.
