Definitions

  • the present invention relates to the provision of interconnections between private networks using the facilities of public networks.
  • the PABX takes on the responsibility for establishing the connections across the pubic network based upon the routing information and, because the public network is not capable of supporting the full range of signalling required to provide the private network services, signalling for the services takes place directly between the PABXs across some other network.
  • a private telecommunications network including an interworking unit for use in interconnecting network to a further private network via a public network using separate signalling and transmission network bearers, the interworking unit comprising an encoder to take the information from the outgoing user side and encode it so that the transmission and signalling information can be carried across separate network and signalling bearers to be decoded at the further private network and a decoder to take incoming transmission and signalling information and using information provided by an encoder correlate the transmission bearers and the signalling information at the interface on the incoming user side.
  • Figure 1 shows a diagrammatic view of an interconnection between two private networks via a public network using the present invention
  • Figure 2 shows the use of the present invention in conjunction with an intelligent network
  • FIG 3 shows a flow chart of the call set up procedure using an intelligent network as shown in Figure 2;
  • Figure 4 shows a diagrammatic representation of the use of the present invention in international communications
  • Figure 5 shows a diagrammatic view of the functioning of Interworking Unit in accordance with the present invention.
  • the interworking unit sits alongside the PABX, providing a virtual network to the PABX. All private network calls route through the IWU which uses a database to translate the incomi Private network number to a public network number and establishes a outgoing call to that public network address across another private interface.
  • the signalling necessary to establish the final part of t call on the other side of the network is sent through the overlay network, the suggestion in this case is that the signalling should X.25 and calls established within the X.25 network as required to support the private network.
  • the signalling between the IWU and the PABX is a single protocol. Wher different protocols are used on the originating and terminating PABXs, protocol conversion will be required.
  • This IWU can be seen as the first of a family of products
  • Speech compression allowing multiple connections to be ma through one bearer across the network
  • X.25 as the protocol between the networks means that all existing public networks can be accessed, all that has to be managed is the relationship between the calling and called sides of the connection across the network to ensure that security is maintained.
  • FIG. 2 is shown the situation where the signalling is routed via the Service Control Point (SCP) of an Intelligent Network.
  • SCP Service Control Point
  • This enables access to services which may be provided by the Intelligent Network, one or more PBX's being connected to a gateway PBX for the network.
  • FIG. 3 shows the flow diagram for the establishment of a call using an Intelligent Network.
  • the abbreviations used are :-
  • CALL INF - Call Information Figure 4 shows the use of the invention including the use of Intelligent Networks, SYS X being the protocol used in the UK and EWSD the protocol used in USA and Germany.
  • FIG. 5 shows the construction of an Interworking Unit (IWU) for use with the invention.
  • IWU Interworking Unit
  • a prime function of the IWU is to convert the signalling protocols between the originating PBX and the terminting PBX based upon information held within the database. The following conversions are needed:
  • the PBX to IWU and IWU to PBX protocols are a choice from CorNet-N, DPNSS, QSIG (or the ISO equivalent), but other protocols can be accommodated within the concept.
  • the Encoder Function takes the information from the outgoing user side and encodes it so that the transmission and signalling can be carried across separate networks and decoded;
  • the Decoder Function takes incoming independent transmission and signalling information and, using information provided by the Encoder correlates the transmission bearers and the signalling information at the interface on the incoming user side;
  • the Splitter separates the signalling and transmission paths at the incoming user side
  • the Compressor compresses the information from a number of user side transmission bearers onto a single network side transmission channel if appropriate;
  • the Router takes the address information in the User Side signalling and generates the Network Side address to be used in the transmission network by examining database information;
  • the Outgoing Correlator adds unambiguous information to the Network Sidesignalling so that the user side signalling can be identified at the destination;
  • the Outgoing Network Interface Originates the Network Side and adds dialing functions to address the destination IWU and switches the bearers from the compressor to free network bearers;
  • the Outgoing Signalling Interface connects the Network Side signalling to the network for the destination IWU;
  • the Incoming Network Interface Terminates the Network side and flags the source to the incoming correlator
  • the Incoming Signalling Interface terminates the signalling network and provides the information to the incoming correlator and the combination processor;
  • the Incoming Correlator identifies the signalling information and incoming transmission bearer and links them together;
  • the Expander extracts the informaton from the network side transmission bearer and generates a number of user side trans ission bearers if appropriate and identifies the information to the Incoming Correlator;
  • the Combination processor takes the incoming transmission connection from the Expander Interface and combines it with the correlated signalling from the incoming signalling interface;
  • the User Side Addresser takes the address information from the Combination Processor to provide the incoming user address.

Abstract

Lorsqu'il est nécessaire de connecter des réseaux privés (PABX) entre eux, on peut effectuer cette liaison en séparant les porteuses des réseaux de transmission et de signalisation et en utilisant le réseau public. Une unité d'interfonctionnement sert à fournier les modifications de protocole nécessaires entre les réseaux privés (PABX) et publics. La signalisation peut être envoyée par des services tels qu'un commutateur de paquets X.25 ou grâce aux dispositifs d'un réseau intelligent.
