Patent

CA 2674098

A solution for the Network Address Translation (NAT) traversal problem for Real Time Protocol (RTP) is provided, which uses an RTP Proxy (e.g., a Session Border Controller (SBC)), instead of being logically located between the NAT and the Feature Server (FS), but instead, for devices which use a protocol unsupported by the SBC, having these devices first signal the Feature Server, which determines whether and how an RTP proxy should be invoked. An RTP proxy should be invoked by the FS if Both endpoints (e.g., devices) are behind different NATs (or one of the endpoints is behind a NAT and the other is not) and neither of the endpoints are already signaled through an RTP proxy. For example, the SBC is interposed (at least logically) between the Feature Server and other shared components.

La présente invention concerne une solution pour le problème de traversée NAT (traduction d'adresse réseau) pour un RTP (protocole en temps réel), qui utilise un proxy RTP (comme un SBC (contrôleur de limite de session)), au lieu d'être situé logiquement entre le NAT et le FS (serveur de fonctions). Plutôt que cela, les dispositifs qui utilisent un protocole non pris en charge par le SBC, ces dispositifs signalant en premier le serveur de fonctions, déterminent si et comment un proxy RTP doit être appelé. Un proxy RTP doit être appelé par le FS si les deux points d'extrémité (par ex. des dispositifs) se trouvent derrière différents NAT (ou si l'un seulement des points d'extrémité se trouve derrière un NAT) et qu'aucun des points d'extrémité n'est déjà signalé par un proxy RTP. Ainsi, par exemple, le SBC est interposé (au moins logiquement) entre le serveur de fonctions et d'autres composants partagés.
