Timeout handler in a service control point

摘要

A method for the handling of time-monitored operations in an Intelligent Network (IN) telecommunications system (1), wherein a time-out event is generated at the expiry of a time-monitored operation invoked by an IN application (25). The time-monitored operations are classified into a number of types of operations (26). Time-out events (31) are processed (32) in accordance with a type of operations invoked, and the IN application (25) responds in accordance with the processed time-out event (31). The following types of operations are defined: class 1: operations which may provide a result or an error message on invoke; class 2: operations which may provide an error message on invoke; class 3: operations which may provide a result message on invoke; class 4: operations which provide no response message on invoke. <IMAGE>
