Patent

CA 2664468

The present invention provides a service node, which extends the services of a carrier's multimedia subsystem (MS), such as an IP multimedia subsystem (IMS), to enterprise networks in an efficient and effective manner. As such, MS subscribers gain access to enterprise services in addition to the carrier's services provided via the carrier's circuit switched subsystems (CS) and packet subsystems (PS). The service node acts as a liaison between enterprise application servers and the MS, such that the enterprise application servers appear as MS application servers to the MS. The service node provides user identifier and protocol translation between enterprise and MS user identifiers and protocols, respectively. As such, enterprise application servers can access the MS as well as be accessed by the MS to support user mobility, with continuity of services, between the enterprise and carrier networks.

L'invention concerne un noeud de service qui étend efficacement les services du sous-système multimédia (MS) d'un réseau opérateur, par exemple les services d'un sous-système multimédia IP (IMS), à des réseaux d'entreprise. Ainsi, les abonnés MS peuvent accéder aux services d'entreprise en plus des services du réseau opérateur fournis par l'intermédiaire des sous-systèmes à commutation de circuit (CS) et des sous-systèmes à commutation de paquet (PS) dudit réseau opérateur. Le noeud de service sert à relier les serveurs d'application d'entreprise et le MS, de sorte que lesdits serveurs d'application d'entreprise apparaissent au MS comme étant les serveurs d'application du MS. Le noeud de service fournit un nom d'utilisateur et une traduction de protocole entre les noms d'utilisateurs et les protocoles de l'entreprise et du MS. Ainsi, les serveurs d'application d'entreprise peuvent accéder au MS et vice versa pour supporter la mobilité des utilisateurs, la continuité des services étant assurée entre le réseau d'entreprise et le réseau opérateur.
