Abstract
The application note describes the implementation of an interactive Unstructured Supplementary Service Data (USSD) service for GSM mobile users. Information is provided to describe how service providers who decide to use the power of USSD to provide mobile users with menu-driven, interactive services such as mobile account balance checking and top up, sports scores, and news and weather information can do so via current technologies and signaling. An overview of the network architecture and a description of interactive USSD services are presented, as well as signaling requirements for such services. Sample code also shows an application that can be developed using the Dialogic ® Distributed Signaling Interface (DSI) MAP Layer. Finally, system design considerations are discussed, showing how high-performance USSD application platforms can be developed with Dialogic ® DSI Components, enabling system designers to offer interactive USSD services worldwide.
