- the networks of the national operators are usually connected to the international head offices of the respective country via national bundles.
- the network of a national operator can be connected to the network of another national operator from the same country, which in turn is connected to the international head office of that country.
- international calls are forwarded to the international head office of the respective country via the network of the other national operator.
- a so-called network identifier is provided to identify the signaling protocol. This provides for four values, two of which are reserved for labeling national and two for labeling international signaling protocols.
- the international signaling protocol between the international head offices is called INATO, the national signaling protocol of each operator is called NATO and the signaling protocol for connecting two national operators with NAT1.
- the fourth indicator INAT1 is currently hardly used.
- a gateway for adapting national signaling protocols are provided.
- a procedure for adapting national signaling protocols is also specified.
- the object is achieved in particular by a method of the type mentioned at the outset, which uses a gateway as the central instance, the gateway carrying out the following steps:
- Interface corresponds to the protocol of the first network
- the object is achieved by a method for adapting different protocols in networks, with a gateway being introduced as the central instance, which carries out the three steps just described.
- a task solution also consists of a switching system for controlling a connection setup and clearing down of individual system components, consisting of: several networks, several roof systems, each of which is represented by a head office, one network being assigned to at least one roof system and the networks being different Signaling protocols can use, and a gateway as a central switching entity, with which at least some of the system components are connected, with: - a receiving unit for receiving signaling data of a first network at a first interface of the gateway, the first interface with the protocol of corresponds to the first network,
- the protocol converter according to the invention for converting signaling protocols from several networks comprises:
- the protocol converter thus converts protocols, in particular signaling protocols, between units that are not adapted to the protocols. It can be designed in software, in hardware or in mixed forms.
- a task solution according to claim 17 consists of a computer-readable medium for storing computer software which, if loaded on a computer used as a gateway, causes the latter to carry out the following steps:
- a further advantage lies in the connection of the gateway according to the invention to an international head office, because it enables those national networks that are not connected to the gateway according to the invention to be reached.
- the gateway is preferably connected to an international head office using an international signaling protocol labeled INAT1.
- INAT1 international signaling protocol
- the signaling data can thus be assigned and / or processed in accordance with this identifier in the gateway and in the international head office.
- the carriers can now be connected directly via the gateway without the need to interpose a head office.
- this increases the efficiency of the connection and, on the other hand, there is a clear cost advantage due to the fact that no head office is involved.
- each of the head offices or only a part of the head offices can be connected to the gateway.
- FIG. 1 shows an international communication network architecture with a gateway according to the invention
- FIG. 2 is a block diagram of a gateway according to the invention.
- the gateway 10 is introduced as a central switching entity.

- the gateway 10 here also called MICG (Multi Interconnectable Gateway) 10, connects various carriers with each other and with any head offices or with international gateways via its various interfaces (INATX, NATX, ).
- the MICG 10 can therefore in particular establish a connection between different carriers in different countries using the ISUP Q.767 protocol with the network indicator NATX. It also serves to connect a carrier with its own or a foreign international gateway.
- the ISUP Q.767 protocol with the network indicator INATX is used.
- SPC1, SPC2 and SPC3 refer to a signaling point code (SPC).
- SPC1 is a bilateral signaling point code between a Weg Global Network (TGN) and a national carrier.
- SPC2 is part of a national operator network in another country and SPC3 is similar to SPC2.
- the signaling point code can also be understood as a country-specific, unique address of a switching entity or a switching office.
- the network is a mobile radio network, in particular according to the GSM (Global System Mobile) or DCS standard (Digital Communications Systems) or an ISDN network and is operated by a carrier, in particular a national carrier.
- GSM Global System Mobile
- DCS Digital Communications Systems
- ISDN ISDN network
- a gateway can also be partially or completely implemented in software and / or distributed over several physical devices.
