USSD Messaging Center
USSD (Unstructured Supplementary Service Data) is a GSM service that enables high-speed interactive communication between subscribers and applications.
The USSD server allows cellular operators to expand their range of services, increase data transmission rates and optimize resource usage.
A USSD session can be initiated by:
- Customer – a subscriber sends a request to start a USSD session. The application generates a response and sends it back to the customer
- Application – a USSD application generates a message and sends it to the customer via the USSD server.
USSD is a session-oriented technology where data exchange is performed within a single session, making USSD similar to IVR. The crucial difference is that a USSD session does not engage voice channels between the application and the subscriber's handset.
CBOSSussd fully supports GSM USSD Phase I & II and includes all the standard USSD features. The system is built around CBOSSasap Advanced Architecture for Service and Application Provisioning, allowing the use of voice applications without any modifications.
- Interactive queries
- Automatic notifications
- Service order/cancellation
- WAP-like features.
CBOSSussd also integrates with various intelligent services providing them with interactive USSD channels.
For example, the integration with CBOSSprepaid Intelligent Prepaid System and CBOSScallbackallows CallBack-based roaming. To order a call, a subscriber sends a USSD command containing the CBOSScallBack code and the destination number. If the incoming call is allowed by the CBOSSprepaid server, the CallBack server establishes two standard connections: one with the caller and another one with the called party thus preventing subscriber debt even in case of prepaid roaming.
In addition, USSD may be used as a means of transport for the SIM Application Toolkit (S@T), powering a SIM card with multi-level dynamic menus for various value-added services. As a result, CBOSSussd provides customers with intuitive access to any service independent of the service provider or handset capabilities.
CBOSSussd also integrates with third-party applications via SMPP.
- Faster response times
- Shorter transactions
- Use of signaling channels
- Control of the operator’s USSD traffic.
