A method for controlling of isdn terminals, the packet-based are connected via an internet network

摘要

More recent communication architectures, the package - or cellular process for the purpose of speech signaltransmission use, the separation of signaling information and which is guided via signalling connections via bearer compounds useful information which is guided before. The separation is effected behind the conventional circuit switched telecommunication networks, such as, for example, isdn. The transmission of isdn - signaling information about the package - or cellular network (ip, atm) takes place by the aid of special internet protocols such as the iua - protocol. In this case, in the event of a fault, the problem can arise that, although the bearer compounds be degraded, the signaling connections, however, not. The present invention provides a remedy in this case, in that a new message in the iua - protocol is provided, with the aid of which the signaling connections as well as the here involved in the isdn - terminals be reset triggered /.
