Abstract

La présente invention se rapporte à un système et à un procédé pour un service d'appel via Internet basé sur un réseau de district. De façon plus spécifique, la présente invention se rapporte à un système et à un procédé pour un service d'appel via Internet basé sur un réseau de district, qui sont aptes à fournir un environnement d'entreprise d'une grande efficacité et à faible coût car ils n'induisent pas de coûts de communication d'entreprise séparés. Selon le système et le procédé de l'invention, des contacts d'entreprise gratuits peuvent être rendus possibles pour des abonnés appartenant à une entreprise sans coûts de communication supplémentaires qui sont toujours supportés par les abonnés, en utilisant des terminaux de district ou des terminaux mobiles, et quelle que soit la position actuelle de l'abonné, via un réseau commuté installé dans une entreprise. D'autre part, le système et le procédé de l'invention sont aptes : à élargir à l'infini le rayon de travail des membres de l'entreprise ; à réduire le temps d'exécution de tâches dû à la perte de contacts d'entreprise ; et à transmettre tous les appels par le biais d'une connexion Internet gratuite basée sur le réseau du district.
