Method for transmitting an identification of a network node unit, associated apparatus and associated program

摘要

The method involves sending a signaling message(s) over a transmission path for controling a connection for the transmission of useful data between two terminals in the network, whereby a message element is automatically inserted into the signaling message requesting transmission of an identifier data item for the partner unit or part thereof. The data item is sent back by the partner unit to the reference unit in a return signaling message. The method involves sending at least one signaling message over a transmission path (26) between a reference network node unit (12) and a partner network node unit (14) in a data communications network (10) for controling a connection for the transmission of useful data between two terminals in the network, whereby a message element is automatically inserted into the signaling message requesting transmission of an identifier data item (NAC2) for the partner unit or part thereof. The data item is sent back by the partner network node unit to the reference network node unit in a return signaling message. Independent claims are also included for the following: a device, especially a switching device, and a program with an instruction sequence for implementing the inventive method.
