Abstract

Components are controlled in a communication system composed at least of a network for transmitting digital communication signals. The network has at least one switching equipment and communication terminal equipment allocated to subscribers multipoint-multiconnection call set up. The components respectively contain control units for controlling a call set up, whereby one component is respectively controlled with signalization information in the form of messages communicated over the network from a different component. Each message contains at least one protocol and message identification, attributes of the object of call, subscriber and connection with object identification numbers for each of the individual objects. Each message also contains information about the relationships between different objects. The information elements of objects are contained in a message independently of the relationship to the other objects. Over and above this, each message separately contains information about the relationships between different objects. The control unit of the controlled component identifies the relationships between the objects on the basis of these additional information.
