Historically,re-rating and billing systems evolved from being process-based to table-driven and, lastly, to script-based. Semantix used the most advanced technology and implemented a script-driven IOT validation, re-pricing and re-rating engine for telecom operators. The engine is built in C++ and dynamically parses a script “rules” file interpreting the operations it prescribes at runtime. Technologies involved: C++, compiler and interpreter development using Flex and Bison For a presentation of the project please contact us.
