摘要 |
The invention concerns a method of operating a communications network of a network operator (OPA), which is interconnected with one or more further communications networks of one or more further network operators (OPB to OPZ) via one or more gateways respectively, as well as such a communications network and an interworking facility (GATECEN) for such a communications network. For each gateway, a gateway switching center (GATE-EX) exchanges information-bearing data with a switching facility (GATE) of the respective further communications network via at least one bearer channel. Furthermore the interworking functions (STP, KDE, TAR, FUNC1 to FUNC3) are performed for all connections via the one or more bearer channel(s) which support the interconnection of the communications network via the respective gateway with the respective further communications network of the respective other network operator (OPB to OPZ). The interworking functions (STP, KDE, TAR, FUNC1 to FUNC3) for all connections of two or more spatially distributed gateway switching centers (GATE-EX) to at least one of the other communications networks (KN2 to KN3) are provided hereby in a common interworking facility (GATECEN).
