During the construction of a call between different communication networks, for example, information of one communication network is replaced by information of the other communication network by the interface system.
  • Interface systems are also used as transceivers between communication networks of different network operators, e.g. used between an in-house and a public communication network or between a fixed network and a mobile network. From the interface system tasks such as the fee collection, the implementation of different

  • address components for each communication network involved in the voice transmission are necessary in the interface system. Address components are first reserved by the interface system for each communication network involved in the transmission. The address components are then signaled to the respective communication networks. This means that during the establishment of a call the address components for the communication network to which the calling subscriber is connected are converted by the interface system into new address components for the communication network to which the called subscriber is connected.
  • Addressing components for the communication networks are already being occupied by the interface system before these are communicated to the communication networks by signaling.
  • Information about the address components is then stored in the interface system and in a so-called registration system, which mainly serves the connection and access control. If necessary, the address components can be reused - for example, when carrying out a call forwarding.
  • the voice connection must be established via the interface system.

Abstract

La présente invention concerne un procédé permettant une meilleure utilisation d'un système d'interface (GW) pour des liaisons entre des abonnés (A-TIn, B-TIn) d'au moins deux réseaux de communication (KN1, KN2) séparés. Au cours de l'établissement d'un appel entre des abonnés (A-TIn, B-TIn), des "composantes d'adresse virtuelles" (vPL1, vPL2, vPR1, vPR2) sont associées par le système d'interface (GW) à chacun des réseaux de communication (KN1, KN2). Les composantes d'adresse virtuelles (vPL1, vPL2, vPR1, vPR2) sont ensuite signalisées à chaque réseau de communication auquel elles ont été associées, et les composantes d'adresse physiques (PL1, PL2, PR1, PR2) dont peut disposer le système d'interface (GW), sont occupées (26, 30) lorsque le système d'interface (GW) a constaté (26, 30) qu'il s'agit d'un appel externe au réseau. L'introduction des " composantes d'adresse virtuelles" (vPL1, vPL2, vPR1, vPR2) permet une meilleure utilisation du système d'interface (GW) et un plus grand nombre d'appels internes simultanés, grâce au fait que les composantes d'adresse virtuelles ne sont signalisées aux réseaux de communication (KN1, KN2) qu'au cours de l'établissement de l'appel. Cela permet une utilisation optimale du système d'interface (GW) puisque les composantes d'adresse (PL1, PL2, PR1, PR2 ) présentes dans le système d'interface (GW), n'ont un taux d'occupation supérieur que dans le cas d'appels externes au réseau.
