Multi-access: several access networks; fixed and mobile terminals. Strong emphasis on security on a managed IP network Enabler for Service Providers Real-time & non real-time communication services between peers or in a client-server configuration Nomadicity & Mobility Both users & devices Intra- & Inter-Network Domains including between Fixed & Mobile networks Interoperability with legacy & new generation services and networks Regulatory compliance Lawful Intercept, Number Portability, Emergency call. 11 IMS in Configurations 12 6
