Network directory concept for an intelligent network

Communications service diversification and network operations integration in the intelligent network require decomposition and distribution of network functions and data. As a means of accessing these distributed functions and data effectively, the network directory is proposed. It provides access management functions, such as a security check for external access and a concealment of distributed network architecture. In addition, a network directory function model for determining the network directory allocation is discussed. The proposed network directory consists of a single logical global directory and a predetermined number of local directories depending on the service system or operation system
