Abstract
In addition to an array of basic call modules each containing a description of a procedure for causing a call state transition from current stable state to next stable state, IN call modules are provided that are activated as tasks independently of the basic call modules. Of the IN call modules, modules equipped with a message generation function contain a description of a procedure necessary for the transmission of a message to a service control point (SCP), and modules equipped with a message analysis function contain a description of a procedure necessary for the analysis of a message from the SCP. When it is determined that a call requires an additional service as a result of DP processing in the basic call processing performed in a basic call module, the basic call processing is interrupted, and an appropriate IN call module is activated. When the IN call processing performed by the IN call module is completed, the basic call module is reactivated to resume the basic call processing.
