Abstract

Dynamically modifiable call processing logic includes creating a Basic Call State Machine (BCSM) which is an instantiation of a dynamically executable Call Model having one or more initialization files and one or more shared library functions. The Call Model supplies the BCSM with Advanced Intelligent Network (AIN) compliant basic call processing logic as well as other features and configuration instructions. The BCSM is provided with a number of states, each of which corresponds to a point-in-call (PIC). Each PIC includes one or more substates and may include one or more trigger detection point (TDP). Each TDP includes at least one trigger. The Call Model, which is used to build the BCSM, includes the number of PICs and TDPs in the BCSM, the number of substates in each PIC, the number of triggers in each TDP, state transition information about which events lead to which PIC, the Call Model specific function calls associated with each substate and trigger, information about which PICs belong to which stage of a call, and the pre-processor and configuration functions. The initialization files include AIN defined events as well as other events defined by the developer, definitions of each PIC, and definitions of each trigger including what function is to be bound to each TDP. The Call Model is written with 'C' language functions and the functions specify which shared libraries contain the definitions of the functions.
