Connection to external applications
PROTEI USSD Server can be connected to any external application using SMPP (for provision of dynamic information services such as currency rates, weather forecasts, account information etc.)
One number, many services
Different subscribers can access different applications using just one USSD service number. The USSD Server can define the type of application not only from the USSD service number, but also from the number of the sender (CgPN) or identifier for a group of senders.
Statistics
Information about the status and text of USSD messages can be stored both within the system and in an external database.
USSD Menu Constructor
The embedded USSD menu constructor enables the operator to create a new menu structure or modify an existing one, significantly reducing the time required to introduce new services.
Reliability and load balancing
System availability is further guaranteed by network architecture and load balancing - when one module reaches a set threshold, excess load is routed to a free module. Should a module fail, traffic is automatically redistributed among other modules and the failed module can be replaced without any interruption to service.
