CA 2246549

Communications are established between a source user (305) and a destination user (307). Data is transmitted between these users in packets (204) having a destination address (205) and communication data (206). A destination name is identified in a first packet and this packet is transmitted to a service control platform (301) identifying, in its communication data, a destination name. A packet is then returned from the control platform (301) to the originating source (305) identifying a real contactable address for the identified destination (307). Subsequent packets of data are generated at the source (305) for transmission to the destination (307) wherein the transmitted packets have the actual destination address, as returned from the service platform, appended thereto.

On établit des communications entre un usager source (305) et un usager destinataire (307). Les données entre ces usagers sont transmises sous forme de paquets (204) comportant une adresse de destination (205) et des données de transmission (206). Un premier paquet, à l'intérieur duquel se trouve un nom de destinataire, est transmis à une plate-forme de commande du service (301) qui identifie, dans ses données de transmission, un nom de destinataire. Un paquet est alors renvoyé par la plate-forme de commande (301) vers la source (305), qui identifie une adresse réelle de contact pour le destinataire identifié (307). Les paquets de données suivants sont générés à la source (305) en vue d'une transmission vers le destinataire (307), les paquets alors transmis comportant en outre l'adresse de destination réelle, telle qu'elle a été renvoyée par la plate-forme de service.
