Patent

CA 2476689

A system and method is provided for interfacing a broadband network (26) and a circuit switched network (28), such as a PSTN (28), that is accessed via a switch (30, 32) that resides in the circuit switched network (28). The system includes a device (34, 36), such as a gateway (34,36), that is located at a point of convergence between the two networks and connects to the circuit switched network (28) through the switch (30, 32). The gateway (34, 36) incorporates call management capabilities and is able to offload call management functions from the circuit switched network (28). The method manages call traffic by identifying a final destination for a call and determining a path for the call to the final destination (Fig. 1). If the path does not need to use the circuit switched network (28), the gateway (34, 36) routes the call without accessing the switch (30, 32).

L'invention concerne un système et un procédé destinés à interfacer un réseau à très large bande et un réseau à commutation de circuits, notamment un RTPC, auquel on accède via un commutateur qui réside dans le réseau à commutation de circuits. Ce système comprend un dispositif, notamment une passerelle, situé à un point de convergence entre les deux réseaux et se connectant au réseau à commutation de circuits via le commutateur. La passerelle permet de gérer les appels et de décharger des fonctions de gestion d'appel du réseau à commutation de circuits. Le procédé de l'invention gère le trafic de communication par identification d'une destination finale pour un appel et détermine un trajet vers la destination finale pour cet appel. Si le trajet ne nécessite pas l'utilisation du réseau à commutation de circuits, la passerelle achemine l'appel sans accéder au commutateur.
