摘要：
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.
