For the participant and his work environment, it does not matter which base station the call is handled. Communication takes place exclusively between the wearer of the handset and another subscriber. Third parties neither have access to the call-specific data, nor are they able to listen to the transmitted voice signals or to start a conference call. This is particularly disadvantageous if the carrier of the mobile part is a member of a working group within which a fast and smooth data exchange is important.

Bocker, ISDN the integrated service digital message network, Springer Vertag, Heidelberg 1990, chapter 4.3 .5.1, Figure 4.23 are shown. From this it can be seen that after the dialing process, a calling end device always sends a SETUP message to the network, which is based on the contracts in PR devices, digital communication networks, Springer contract. Heidelberg 1991, page 360, Table 7.5 elements listed.
  • the first step in establishing a connection between the terminal EGx and the mobile part MT1 is that a connection to the special terminal SE1 is first established in a known manner.
  • the special end device SE1 is required the destination address of the terminal to be called. This address is known to the special terminal SE1 if the handset MT1 is to be called.
  • the terminal EGx If, however, the terminal EGx is to be called, its destination address is written in the mobile part MT1 as user-user information in the SETUP message. If the possibility of entering user-user information is missing, the ISDN interface also makes it impossible to insert a called-party number (ISDN message element which contains the call number of the called subscriber). Instead of the control functionally via ISDN protocols, control routines can also be triggered in the switching center by means of stimulus terminals.
  • the processor MP provided in the special terminals SE1 provides e.g. The originating address determines that a call has arrived from the handset. The signals arriving via the voice channel are then checked, which may contain instructions for weather transmission and the telephone number of a terminal EGx. The field of the target address of the SETUP message remains reserved for the target address of the special terminal SE1.
  • the special terminal SE1 In the SETUP message compiled by the special terminal SE1, the number of the terminal EGx transmitted as user-user information or with the multi-frequency method (DTMF) is entered in the field of the destination address, so that a connection to the terminal EGx is established in a known manner can.
  • the special terminal SE1 is therefore connected to the calling and the called terminal EGx, MT1 at this point.
  • the connection of the voice channels B1, B2 belonging to these connections enables the terminals EGx and MT1 to exchange information. Basically, therefore, a connection is first established from the calling terminal to the special terminal SE1 and then a connection from the special terminal SE1 to the called terminal.
  • the origin address of the calling terminal EGx can be displayed in the mobile part MT1, this must be taken from the incoming SETUP message in the special terminal SE1 and the outgoing SETUP message must be transmitted.
  • the special terminal SE1 could also accept the incoming SETUP message and write the destination address of the handset MT1 or the terminal EGx in it.
  • the handset MT1 can of course only request a connection to the special terminal SE1. This can e.g. by means of a message in the field user-user information. For the sake of simplicity, however, the field user-user information is left empty, from which the special terminal SE1 can see that no weather connection is desired.
  • the destination address ⁇ or phone numbers of the special terminal SE1 and the handset MT1 must therefore be different. However, it is sufficient if the destination address of the mobile part MT1 only the special the terminal SE1 is known, since connections to the mobile part MT1 are always established via the special terminal SE1.

  • the MUSAC integrated circuit from Siemens AG can be used as the CONF conference module, which basically has the functions of a signal processor.
  • a building block of this type offers the possibility, in a processor-controlled manner, to mix all of the highways of several highways as desired.
  • the special terminal SE1 is connected to a connection for switching centers at the switching center VSTa, the connection is established between the terminal EGx and the mobile part MT1 by completely writing the phone number in the field for the destination address of the SETUP message. So that the special terminal SE11, which acts as a switching center, is included in the connection establishment when searching for a route, its address must be included as part of the destination address. If e.g. a connection to the terminal EGx is established from the mobile unit MT1 via the base station BS1, the switching center VSTa and the special terminal SE1, the mobile unit MT1 manually or automatically first dials the number of the special terminal SE1 and then the number of the terminal EGx into the field for the destination address of the SETUP message is written. Since the special terminal SE1 acts as a central exchange and not as a terminal in the network, it connects the connection without changing the number of the terminal EGx. Nevertheless, there are options in the special terminal SE1 for listening in or for making a conference call.
  • the processor MP of the special terminal SE1 preferably always checks the origin address in the corresponding field of the incoming SETUP message. If the source address corresponds to the address of the handset MT1, the processor MP determines whether the handset MT1 in the B channel e.g. instructions from the subscriber arrive by means of the multi-frequency method or via the user-user information (or further transmission channels available).

Abstract

Un système de communication comprend un centre de commutation RNIS (VSTa) auquel est raccordé au moins un terminal spécial (SE) pourvu de transducteurs électroacoustiques (MIC, LS), une partie mobile (MT) étant associée au terminal spécial. Les terminaux spéciaux (SE1, ..., Sen) sont pourvus d'un processeur (MP) et d'une unité d'intercommunication (SWUe) qui permet d'établir une liaison entre un terminal (EGx) et la partie mobile (MT1; MT2; ...) associée au terminal spécial (SE1; SE2; ...). Afin d'établir la connexion entre la partie mobile (MT1; MT2; ...) et le terminal (EGx) par l'intermédiaire de l'unité d'intercommunication (SWUe), l'adresse du terminal destinataire (EGx) est transmise au terminal spécial (SE1; SE2; ...) de sorte que celui-ci (SE1; SE2; ...) puisse recevoir cette information et établir la communication. Le terminal spécial (SE1; SE2; ...) comprend également des éléments de surveillance de la communication et/ou d'enregistrement des conversations téléphoniques. Toutes les conversations tenues par le porteur de la partie mobile (MT) peuvent ainsi être suivies depuis son poste de travail. Le système permet également d'établir des conférences téléphoniques ou de déclencher des fonctions (enregistrement des conversations, alarme, etc.) du terminal spécial (SE1; SE2; ...) par télécommande depuis la partie mobile (MT1; MT2; ...).
