There are fewer questions about developing Parlay applications in the world now since Ericsson Mobility World launched its "Ask the expert" campaign. At the close of the promotion on May 30, response had been greater than expected.

Anyone who has enjoyed the convenience of a mobile phone has probably also suffered the frustration of a missed call. Telecom Application Specialist Infitel International N.V. has turned this headache into a winning cure with its Parlay-based Advanced Call Completion application.

When Ericsson Mobility World started its Developer Days in 2002, technologies such as positioning, MMS and WAP were the ones to watch. The buzz in 2003 was about mobile media, which really took off during 2004. The founder of the Developer Days, Jörgen Odgaard, says that focus in the future will be on legal matters, Network Resource Gateway Parlay/OSA, IPX and IMS the years to come.

The location-based game Treasure Hunt won first prize in Excitera Charon, Ericsson's mobile application award for students.

It only took a few weeks for Colombian developer Élibom to adapt its enterprise applications for the Parlay/OSA standard after it attended the Ericsson Mobility World Developer Day in Bogotá.

When developing an Ericsson Network Resource Gateway/Parlay application a good start can save you a lot of time. Do not start coding directly, but take time to prepare yourself, and your colleagues, for your next application.

Parlay technology has matured, the initial hurdles are gone and operators are deploying Parlay gateways were messages delivered at the recent Parlay members meeting in Miami. Ericsson's presence at the event was indisputable as a driver of standards and market leader in Parlay gateways.

Ericsson offers all the support you need to launch Parlay/OSA applications. Start with our Parlay/OSA introduction and training, use our free SDK to develop and then test your application with our simulator. We even offer live network testing and technical consultation.

Want to integrate, for example, MMS, SMS, call control, user location, or user status with your applications? Parlay/OSA provides interfaces for these capabilities, making them easy to use. Ericsson's NRG SDK for Parlay/OSA application development lets you create applications for Ericsson's Network Resource Gateway.

Designing the next killer application means knowing more than just mobiles. The mobile network service layer is becoming increasingly sophisticated, allowing application developers to bring great new ideas to life.
