Definitions

  • the present invention relates to a method and a device for connecting subscribers to a telecommunications network in a switching center, which have an input for receiving signaled data, a means for forming and processing connection-controlling data from the data received on the input side, and a means for Signaling the processed data at their output has.
  • connection control In the case of known systems, the sequence program of the connection control must be changed accordingly in order to be able to use new services or information, that is to say the logic for evaluating and modifying connection-controlling data must in principle be reprogrammed.
  • this involves a considerable effort, which causes high costs for the network operator.
  • connection control also causes errors that can lead to sustainable problems.
  • connection-controlling data is converted into neutral parameters independent of the original format of the data by means of a predetermined assignment with the aid of a predetermined parameter list, and these parameters are processed in their neutral format by the switching center and the data to be signaled on the output side are formed by the predetermined assignment with the aid of the parameter list from the neutral parameters by reverse conversion.
  • a device for solving the above-mentioned object accordingly has a means for converting connection-controlling data into neutral parameters with the aid of a predetermined parameter list, a means for processing these neutral parameters independently of the original format of the connection-controlling data and a means for converting back the processed neutral parameters in connection-controlling data using the parameter list, these back-converted data being sent to the connection control at the exit of the exchange.
  • a data conversion unit and a data modification unit are provided according to the invention, the data conversion unit being set up to evaluate the data received on the input side after conversion into neutral parameters, and the data modification unit is set up to set up the neutral ones Parameters either depending on the result of the evaluation by the data conversion unit or depending on the result of the assignment by the means for converting or to change depending on the control parameters on the output side.
  • This "neutralization" of the connection-controlling data regardless of the signaling method or the format and the definition of this data, advantageously makes it possible for the data to be assessed and modified uniformly for all signaling methods and data formats.
  • each neutral parameter depending on the signaling method used e.g. TUP, ISUP, MFC-R2
  • TUP signaling method
  • ISUP ISUP
  • MFC-R2 multi-media interface
  • connection-controlling data are those that are used in the different signaling methods as messages for establishing the connection (mandatory and dialing messages) or message content are defined, for example the entries of the initial address message (IAM) or sequential address message (SAM) of an ISUP transmission protocol, each message or each individual message part, for example each entry of the ISUP message (IAM, SAM), with the help of the parameter list, each converted into a neutral parameter for further processing by means of a data conversion unit and a data modification unit.
  • IAM initial address message
  • SAM sequential address message
  • FIGS. 1 and 2 schematically showing the structure of a device of the type according to the invention.
  • connection controller for switching through calls from a subscriber A to a subscriber B, which are linked to one another via a connection controller.
  • the connections can be of different types, e.g. Individual connections, private branch exchanges, mobile connections, connections for connecting lines and connections for databases and / or control computers. These connections can be assigned analog or digital, whereby fundamentally different protocol variants, e.g. for digital connections ISUP, TUP, ISDN, GSM, DECT etc. are available.
  • connection-related data are stored in the exchange, which are required by the exchange for connection control.
  • Fi gur 2 are the connection-related data with DATA A; DATA denotes B, with A the connection data of the input connection and B the data of the output connection.
  • a signal is now received by the exchange at one of the inputs, the data transmitted in this signal must be converted into a neutral format according to the invention.
  • This data assignment is carried out by a logic DZO A, which has access to the assigned connection-related data DATA A as well as access to a parameter list PARAMETER, in which the assignment rules for converting format-related data into neutral parameters are stored.
  • a certain number of possible parameters is defined in the parameter list, e.g. PARI, PAR2, PAR3, ...., PAR256, a set of assignment rules being specified for each parameter depending on the possible signaling.
  • CCS Common Channel Signaling

  • SAM Sequential Address Message
  • certain data are stored in individual entries which are relevant for the connection control, for example category of the A subscriber, call number of the A and B subscriber, desired service (voice, fax, modem) etc.
  • IAM or SAM Sequential Address Message
  • Each parameter required by the connection controller is assigned an abstract value, for example a numerical value or a string, when the logic DZO A is used.
  • the assignment depends on the signaling method used, so that there is a specific parameter definition for each supported signaling method and for each parameter of the parameter list PARI, ..., PAR256.
  • the parameter definition also specifies whether the entry is in an IAM or a SAM (Message ID).
  • information about the expected result can also be contained in the parameter definition, for example a value range, a number of digits or the like. If individual parameters are not supported by a signaling procedure (e.g. with analog signaling), these can be set to default values by the data assignment logic DZO-A if they are needed later. If necessary, the default values can also be generated during the subsequent evaluation and modification of the neutral parameters.
  • the neutral parameters formed by the data assignment logic DZO-A are now further processed by a data conversion unit UMW.
  • a standardized sequence program for evaluating the neutral parameters is installed in this data conversion unit UMW in order to obtain a connection control-relevant result from these neutral parameters.
  • a data modification unit MOD is activated for this purpose, which modifies the transferred parameters according to the requirements.
  • the result of the modification is usually passed back to the data conversion unit UMW for the new evaluation of the modified parameters.
  • the need to modify individual neutral parameters can already be determined by the data allocation logic DZO A.
  • the data modification unit MOD can be controlled directly by the data assignment logic DZO A.
  • a data assignment logic DZO B which generates the format-related data for the signal to be sent using the parameter list and the connection-related data DATA B, e.g. a new IAM or SAM, which is then sent to the relevant output.
  • connection or control data DATA B required for the modification are converted into a neutral format by means of the data assignment logic DZO A and processed accordingly by the data conversion UMW and the data modification unit MOD.

Abstract

L'invention concerne un dispositif permettant de mettre en relation des abonnés d'un réseau de télécommunications dans un central téléphonique, qui comporte une entrée pour recevoir des données sous forme de signaux, un élément pour former et traiter des données pilotant la communication à partir des données reçues côté entrée et un élément pour assurer la mise en signaux des données traitées à leur sortie, ainsi qu'un élément (DZO A) pour convertir les données pilotant la communication en paramètres neutres à l'aide d'une liste de paramètre prédéterminée, un élément (UMW, MOD) pour traiter ces paramètres neutres indépendamment du format initial des données pilotant la communication et un élément (DZO B) pour reconvertir les paramètres neutres traités en données pilotant la communication à l'aide de la liste de paramètres, afin de pouvoir transmettre ces données reconverties après une évaluation ou une modification à la sortie.
