摘要

The control component (S) functions in a system incorporating several service suppliers and several network suppliers to make it possible for a network supplier, independently of the network technique used, to handle information defining, calling up and providing network services in a telecommunication network. The network incorporates a connectivity network, comprising network components and links and connecting points for subscribers together with connected network service functions. The control component (S) is divided into a hierarchy of layers (L1,L2,L3,L4) which are independent with interfaces (G,G4) transmitting information between the layers in a well-defined manner. Each layer has its own handling and operating system.
