A method of transferring signalling messages between an Internet Service Provider (ISP) (4) and an exchange (2) of a telecommunications network for the purpose of allocating and controlling circuit switched communication channels between the exchange (2) and the ISP (4). The method comprising routing the signalling messages via an SS7/IP gateway which provides for conversion of messages between an SS7 protocol used in the telecommunications network and an IP based protocol used in the network which connects the SS7/IP gateway 7 to the ISP 4. For each message received at the SS7/IP gateway 7 from the ISP 4, the SS7/IP gateway 7 confirms the right of that ISP 4 to control a circuit switched communication channel identified in the message.

L'invention concerne un procédé de transfert de messages de signalisation entre un fournisseur d'accès Internet (ISP) (4) et un central (2) d'un réseau de télécommunication dans le but d'affecter et de contrôler des canaux de communication par commutation de circuit entre le central (2) et le fournisseur ISP (4). Ce procédé consiste à acheminer les messages de signalisation via une passerelle SS7/IP qui assure la conversion de messages entre un protocole SS7 utilisé dans le réseau de télécommunications et un protocole IP utilisé dans le réseau qui connecte la passerelle SS7/IP au fournisseur ISP (4). La passerelle SS7/IP (7) confirme le droit octroyé au ISP (4) de contrôler un canal de communication par commutation de circuit identifié dans le message pour chaque message envoyé par ISP (4) à la passerelle SS7/IP (7).ig. 1 ne rien traduire
