Definitions

  • the present invention relates to a method for operating a telecommunications network, or TK network for short, in which a network element at a network node of a TK network is controlled by a control computer.
  • the network element is, for example, a switching center for switching connections.
  • An application computer is connected to this control computer and, in addition to the operating system assigned to it, has at least one application program. With the help of the connection between the application computer and the control computer, the application program has access to the signaling system of the control computer and thus to the signaling system of the telecommunications network.
  • the invention relates to an arrangement for operating a telecommunications network and a telecommunications network.
  • the signaling system No. 7 is preferred, as is the case, for example, in the relevant standards of the ITü (International Telecommunication Union) with its organ ITU-T, formerly CCITT (International
  • the signaling takes place with the help of central signaling channels between the network nodes of the telecommunications network.
  • the signaling system provides a message transfer part (MTP) that is uniform for all applications.
  • the message transmission part is a signaling protocol which enables fast, reliable and application-independent transport, especially of the signaling messages in the network, including the registration and correction of system and network errors.
  • the message transmission part only offers services that are independent of user connections and have limited addressing capabilities.
  • the message transmission part provides services for a wide variety of users (users) and forms the common transport system for messages from different user parts (User Part, UP). For example, there is a user part for telephony, the Telephony User Part (TUP), a user part for circuit-switched data services, the Data User Part (DUP), a user part for operating and maintenance tasks for networks, the Operation and Maintenance Application Part (OMAP).
  • TUP Telephony User Part
  • DUP Data User Part
  • OMAP Operation and Maintenance Application Part
  • the message transmission part thus serves above all to control the connection of the circuit-switched data transmission in order to connect the network elements of network nodes, which are also referred to as signaling points (signaling points), in signaling network no.
  • signaling points signals
  • digital full-duplex 64 kbit / s lines or channels are preferably used as signaling lines.

  • Protocol stacks saved it also saves the considerable time required to implement these protocol stacks on the application computer as well as the necessary maintenance and care of the SCCP / TCAP protocol stacks.
  • the first and second interface programs form an interface between the application program and the TCAP protocol and are also referred to as TCAP Application Interface (TIF).
  • TCAP TCAP Application Interface
  • the first interface program exchanges signaling information with the TCAP protocol stack like a user part of the user.
  • the second interface program exchanges signaling data with the application program in the same way as when the user program directly accesses a TCAP protocol stack implemented in the application computer.
  • the data exchange between the two interfaces is carried out using any data transmission protocol.
  • the effort to implement the two interfaces is approximately 10% of the effort required to implement the SCCP / TCAP protocol.
  • the signaling data are transmitted as user data between the two interfaces. A simple and uncomplicated logical structure of the two interfaces is thus possible.
  • Interface monitoring such as protocol monitoring and route search
  • the interface control can also continue to be used unmodified after a change in service features. At least the first interface can continue to be used unmodified in future extensions on other platforms. It is only necessary to adapt the second interface to the new platform, ie the interface must be implemented on the new platform, for example on another data processing system, unless the interface is in a platform-independent programming language, ⁇ ⁇ (V ) N) P 1 P 1

  • the second interface program 82 can also be used unmodified on other platforms, unless it is necessary that to create a second interface program, for example for performance reasons, in a platform-dependent programming language of this platform, but due to the simple structure of the second interface program 82, no great effort is to be expected for the creation.
