DESCRIPTION:
BRIEF SUMMARY
THIS APPLICATION IS A 371 OF PCT/DE96/01131 FILED ON JUN. 20, 1996.
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to the field of telecommunications, and, more particularly, the present invention relates to the use of process controlled modules in a communication system.
2. Description of the Related Art
Communication systems, in particular private and public switching installations, contain predominantly program-controlled modules that are constructed in different ways with respect to circuitry and programming, depending on the configuration of the communication system and on the greatly varying signalings and transmission methods used in the communication networks. A communication system with a module design of this type is known for example from the reference "ISDN in the office, HICOM", pp. 56 to 64 in particular, 1985, Siemens. Each of the modules, e.g. the signaling unit or the trunk modules, is hereby equipped with a control unit, i.e. a microprocessor, and the required circuit-oriented components, such as e.g. subscriber terminal interfaces or interfaces for the internal communication exchange exchange. These are respectively arranged on the modules. The greatly varying circuit-oriented and program-oriented realizations of the modules provided for this purpose mean that a multiplicity of different modules must be provided for a communication system, which increases further due to further circuit-oriented and program-oriented developments of the modules. The multiplicity required is connected with an increased economic expense or, respectively, with increased costs in manufacturing (greatly varying equipment variants), in testing (a multiplicity of test programs) and in warehousing (outlay of space and management) of the modules.
SUMMARY OF THE INVENTION
One underlying object of the present invention is to reduce the economic expense caused by the multiplicity of modules.
Another aspect of the inventive method is that the circuit-oriented and procedural functions of a functional area of a communication system, i.e. of an area with similar functions, are combined on one area module. For example, an area module represents a signaling module allocated to central control, on which module all circuit-oriented components are combined that are required for the processing of all signaling procedures provided in the communication system. The circuit-oriented and procedural functions that can be realized by the area modules--in relation to the signaling module, the possible signalings and the variants thereof--are specified, i.e. determined, by the combination of a circuit technology identification and at least one function identification. In addition, at least one technology identifications and function identifications. The program module is a computer program which realizes, the procedural function or, respectively, the procedural functions of the function or, respectively, functions determined by the combination of the identifications. In addition, by means of the at least one program module circuit-oriented settings--e.g. switching active or inactive--of the circuit-oriented components can be effected by correspondingly inserted items of information. The at least one program module can be stored in the communication system itself (e.g., hard disk, streamer CD-ROM), in a memory placed at the disposal of the communication system (e.g., CD-ROM), or in a service center in the respective communication network. This can respectively be transmitted from there to the area module, using the central control.
Given a configuration of the communication system, e.g. during commissioning or during this change of the configuration of the communication system, a combination--determined by the central control unit--of a circuit technology identification and at least one functional identification is transmitted to the area module to be set up, and is stored in this module. By storing the combination of the two identifications, the respective area module is specified, i
