2TELEFÓNICA I+D


MotivationsWhy?

Current fixed platforms require complex user-provisioning processes.

Simplify process and reduce OPEX!!!

User identity is attached to the physical access line.

Enable nomadic services!!!

Mobile and fixed networks have different authentication mechanisms.

Design a convergent Platform!!!

PPP does not support multicast IPTV traffic.

Native support of Triple-Play and Advanced Services!!!

Req. 1: Access LineIndependent User-Identity

Req. 2: Fixed-MobileConvergence

Req. 3: Well-defined andwidely deployed Protocols

Req. 4: Enable Triple-Play Services

ConclusionsPros and Cons

Home Gateway hardware becomes more complex (Smart Card reader)

Convergent QoS Architecture and user location retrieval is not full defined yet.

05 Unified fixed and mobile authentication

platforms (TISPAN & 3GPP).

Zero-provisioning systems.

Advanced services for residential users: nomadism
