Method for establishing virtual connections in packet switching networks.

摘要

Following a call packet by means of which setting-up of a virtual connection within a first packet switching network (PVN1) is requested, an alternative connection including a second packet switching network (PVN2) is set up if no connecting path exists. Within the second packet switching network, the relevant call packet and signalling packets and data packets following the former, of the relevant virtual connection are transparently transferred in data packets of the alternative connection.
