The present invention advantageously provides several systems and methods for solving the trombone routing issues within an IMS/MMD network. These approaches avoid trombone routing, speed up handoff, and increase the efficiency of signaling and overall performance of an IMS/MMD network. These solutions can broadly be divided into the following categories. Piggy-backing SIP registration over MIP (Split at FA); Selective Reverse Tunneling and Tunneling between FA and P-CSCF; the SIP-based mobility protocol; use of CoA during SIP registration and call up in MIPv6; Piggy-backing SIP registration when HA and S-CSCF Co-exist; Using Dynamic Home Agents in MIPv4 FA-CoA; and the Interceptor-Caching Approach.

La présente invention porte sur divers systèmes et procédés qui permettent de résoudre les problèmes d'acheminement à effet "trombone" dans un réseau IMS/MMD. Les procédés de l'invention permettent d'éviter l'acheminement à effet "trombone", d'accélérer le transfert et d'augmenter l'efficacité de la signalisation et la performance globale d'un réseau IMS/MMD. Les solutions apportées par l'invention peuvent être classées en plusieurs grandes catégories: l'enregistrement SIP intégré dans le MIP ("piggy-backing") (divisé à l'emplacement du FA); la tunnelisation inverse sélective et la tunnelisation entre le FA et le P-CSCF; le protocole de mobilité fondé sur le SIP; l'utilisation de la CoA pendant l'enregistrement SIP et l'appel dans le MIPv6; l'intégration de l'enregistrement SIP par "piggy-backing" lorsque le HA et le S-CSCF coexistent; l'utilisation d'agents locaux dynamiques dans le MIPv4 FA-CoA; et l'approche de la mise en cache avec interception.
