A software structure for flexible IN service operations

To provide a network that can meet customer demands quickly and economically, we are developing an advanced Intelligent Network (IN). These days, service management and operations are an important area of study in advanced INs. The provision of flexible operations using Operations Logic Programs (OLPs) has become a particularly topical issue. Since support for various advanced IN services will be added to our network quickly, new service-dependent operations functions must be provided immediately to support the services on demand. Existing OpSs, however, generally focus on one or more existing services, so it is difficult that they can handle new ones quickly. To compensate for the lack of new operations functions in existing OpSs, we are developing a service operations system (SOpS) and service operations workstations (OpWSs). These each have their own Service-Independent Operations Platform (SIOP). They also have Service-Independent/Dependent Operations Function Building Blocks (SI/DOFB), like Service Independent Building Block (SIB). The SIOP can execute OLPs by using these SI/DOFBs. The SOpS and OpWSs consequently enable flexible advanced IN service operations. This presentation first explains NTT's advanced IN architecture. Next, we discuss the requirements of the SOpS and OpWSs. Then, we overview their system structures, OLPs, and SIOPs. Finally, we describe how to install new service-dependent operations functions on them.
