CA 2434521

Session Initiation Protocol (SIP) is used to communicate with Network-capable appliances (340). In a system employing SIP, a remote user agent client (UAC) sends a message over the Internet via a Proxy server (320) to a user agent server at the location of the appliances (340), e.g., the client's home. This communications channel allows the client to control the appliances and to determine their status. The Proxy server (320) between the UAC and a plurality of UAS processors has the address mapping, authentication, authorization and/or translation functions out-sourced from the UAS processors to the Proxy server (320) connected to them.

Le protocole d'initiation de session (SIP) est utilisé pour communiquer avec des appareils (340) connectables à un réseau. Dans un système faisant appel au protocole SIP, un client d'agent d'utilisateur (UAC) éloigné envoie un message par Internet par l'intermédiaire d'un serveur mandataire (320) à un serveur d'agent d'utilisateur (UAS) à l'emplacement des appareils (340), p. ex. chez le client. Ce canal de communication permet au client de commander les appareils et de déterminer leur statut. Le serveur mandataire (320) entre l'UAC et une pluralité de processeurs UAS se voit impartir les fonctions de mise en correspondance d'adresses, d'authentification, d'autorisation et/ou de traduction, externalisées des processeurs UAS audit serveur mandataire (320) connecté à ceux-ci.
