Abstract: In a telecommunication network, a method of creating, in response to inputs from an operator of a record creation system, a general service specification for a call processing record. The call processing record includes logically related nodes and branches. In the method, a processor in the record creation system prompts the operator to identify at least one optional node, at least one required node, and at least one restricted node from a node set presented to the operator. Optional nodes are nodes which may appear in a call processing record associated with the general service specification; required nodes must appear in the call processing record associated with the general service specification; and restricted nodes cannot appear in the call processing record associated with the general service specification.

Abstract: A call processing record for execution in a telephone service execution environment of a telecommunication network. The call processing record includes a record header which associates the call processing record with one or more corresponding telephone service subscribers. The call processing record further includes one or more call processing logic sections, one or more local data sections, one or more entry points, and a global data section. The local data sections are associated with an entry point in a corresponding logic section and store data executable only by the associated call processing logic. The entry point identifies the associated call processing logic section. The global data section includes data executable by each of the call processing logic sections.
