Unstructured Supplementary Service Data (USSD)
The Unstructured Supplementary
Service Data (USSD) is a communication technology used to send
text between a GSM cell phone and an application program in the
network; it is mostly used to query information and trigger services,
providing an exciting end-user experience, over almost any handset
USSD transactions cannot take place while the telephone is turned
off or out of range (like SMS), but unlike regular text messages,
USSD messages travel over GSM signaling channels, providing a
fast way for customer connection, download contents or money transfers.
While the response time of an SMS transaction is between 5 and
10 seconds, the same process through USSD has an estimated response
time of 200 milliseconds.
Applications using USSD:
The LeibICT Integrated Value Added Services (iVas) Gateway represents a new concept of integration on USSD, LBS and SMS services into a single, high performance module, without losing control of the networks.
The Unstructured Supplementary Service Data (USSD) allows cost-effective, interactive communication between subscribers and application across a UMTS/GSM network. Its functionalities make it ideal for information queries like available balance, content downloading and any information services.
||USSD Developer Kit
LeibICT UDK is the first comprehensive kit for documentation, samples and simulators that enables any Java or C++ programmer either on Linux (32 and 64bit variants) or Windows to develop a USSD Service within minutes.
Other applications available:
- Location Services
- Information Services (weather, news, horoscopes, jokes, sports...)
