Why Brasil Telecom choose IMS/TISPAN NGNWhy Brasil Telecom choose IMS/TISPAN NGN
• TISPAN defines a new telecommunications network for broadband fixed access and facilitates convergence of networks and services.
• IMS/TISPAN provides:
• a multi-service, multi-protocol, multi-access, IP based network - secure, reliable and trusted:
• Multi-services: delivered by a common QoS enabled core network.
• Multi-access: several access networks; fixed and mobile terminals.
• Not one network, but different networks that interoperate seamlessly.

• enabler for Service Providers to offer:
• real-time and non real-time communication services;
• between peers or in a client-server configuration;
• interworking towards circuit switched voice.
• Nomadicity and Mobility:
• of both users and devices;
• intra- and inter-Network Domains, eventually between Fixed and Mobile networks
• IMS maintains Service Operator control for signalling & media traffic.
