June 26, 1997 -Ericsson, Motorola, Nokia, and Unwired Planet (now Phone.com), today announced plans to co-operate in defining a common Wireless Application Protocol. The initial proposal to develop the new protocol was first presented at MDI (Mobile Data Initiative) this spring in Munich.

The initiative is aimed at aligning the companies' efforts to bring advanced applications and Internet content to digital mobile phones. This alignment will result in numerous benefits, among them providing operators differentiation and new business opportunities. In addition, developers of applications and content will be aided, since a single protocol and markup language will work with any vendor's compatible handsets.

For the end users, this co-operation will permit, via mobile phones supporting the Wireless Application Protocol, access to applications and functions such as:

Management of personal telephone profiles Handling of voice, fax, and e-mail, i.e. unified messaging. Information services: taxi, restaurants, hotels, stock trading, banking, directory services, etc. Internet services by transforming intelligent mobile phones and other wireless handheld devices into first class citizens of the Internet. Improved user interface to existing and addition of more advanced telephony related services.

The goal of this effort is to produce a refined, license free protocol which is independent of the underlying airlink standard. The Wireless Application Protocol will inherit its main characteristics and functionality from HDML (Handheld Device Markup Language) and HDTP (Handheld Device Transport Protocol) developed by Unwired Planet (now Phone.com); the Smart Messaging specification developed by Nokia; and the ITTP (Intelligent Terminal Transfer Protocol) specification developed by Ericsson. The aim of the Wireless Application Protocol is to leverage the best of the three approaches - the Internet standards of HDML and HDTP, the services and feature control as well as Internet access of Smart Messaging based on TTML (Tagged Text Mark-Up Language), and the call control and messaging functionality of ITTP.

By working together, each of these leading companies will contribute to the prompt development of an open wireless application protocol that will encourage growth in the market for intelligent mobile phones. The participating companies stress the importance of a totally open and licence as well as royalty free protocol toward this end.

The protocol will be available to vendors and mobile operators around the world. The result will be innovative information access and applications for a new generation of mobile phones. The first protocol specification will be published on the World Wide Web by September 15, 1997. It is important to note that the new protocol will be transport independent and it will utilise the Narrowband Sockets specification for wireless communication. The protocol will accommodate the different capabilities and functions -- memory, displays, and keypads of various manufacturers' devices, in a modular fashion.
