SIP-Based Fixed Mobile ConvergenceIMS Approach

  • Distributed session control for voice, video, and messaging services

  • Centralized session routing, hierarchical LDAP directories, advanced routing capabilities (i.e. ENUM, IP centrex)

  • Distributed registration and access control (AAA)

  • IMS logical architecture for convergence with mobile 3G-WiFi packet and IP networks, fixed and mobile
