3GPP R4 - separated call control and transport for CS WCDMA networks
3GPP R5 – first introduction of SIP-based IMS
3GPP R6
3GPP R7 - adds broadband / wireline access capabilities
3GPP2 – defined CDMA2000 multi-media domain (MMD) based on 3GPP IMS R5
TISPAN – defines NGN architecture for fixed access networks
ITU-T NGN Focus Group – venue to make TISPAN NGN a global spec
ATIS NGN FG – formally collaborating with ETSI as of April 2005
PacketCable Release 2.0 – specifying portions of 3GPP

Why 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.

Why Brasil Telecom choose ETSI/TISPAN
• 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.

Release 1 – PSTN Replacement & Multimedia - Major Achievements:
• PSTN Emulation (PES) – Softswitch and IMS based
• Real time Voice/MM communication services
• Messaging (Instant Messaging, MMS), Presence Management
• Nomadicity / user-controlled Roaming
• IMS support for Transit Calls
• Security: Location based; SIP digest in addition to SIP AKA
• RACS/NASS
• Secure IMS Core
• NAT/Firewall
• Network Asserted Location
• Supplementary Service – Extend SIP capabilities

What are the advantages of being part of an organization which
establishes the standards?
• To protect the investments already realized;
• To avoid wasteful duplication of investments;
• To know the standards deeply;
• To be able to influence the definition of the standards;
• To assure that the characteristics of Brazilian network
are taken into consideration.

Brasil Telecom’s actions related to international forums
• Brasil Telecom is the founder-member of FMCA.
• It is participating effectively of TISPAN and 3GPP meetings since
July 2005.
• It has been presenting contributions to TISPAN work groups,
mainly to subjects referring to FMC and network architecture.
• In November 2006, Brasil Telecom hosted the first TISPAN meeting
out of Europe.
• Brasil Telecom launched a RFI based in IMS R6 and TISPAN R1 in
September 2006.

Three years ago…
• There weren’t Skype, Google Talk, i-Tunes store, Orkut,
You Tube etc.;
• Ericsson and Marconi, Alcatel and Lucent, Siemens
and Nokia were competitors;
• IMS was a standard only for mobile networks;
• There wasn’t TISPAN;
• The PSTN replacement would be through softswitch.
