Currently, new telecommunication services that are planned to be offered require the addition of functions to switching systems. This is because service specification translation processes and service execution processes are implemented in a dedicated fashion for each new service. The service-, vendor-, network-independent Intelligent Network (IN) architecture is expected to play an important role in introducing new services rapidly and efficiently. This paper proposes the service creation and execution domain concept for IN. This concept defines the scope for interactions and general rules accesses between services, functions, and data. Based on the identified functional requirements for IN service creation and execution processes, this paper discusses the roles of the proposed service creation and execution domain concept. It also discusses the hierarchical domain types in relation to the identified IN participants, and it identifies the general rules for the proposed domain concept, considering the IN studies in the CCITT, especially the IN Conceptual Model and IN Application Programming Interfaces.
