The Internet phenomena !!! The mobile market boom !!!! 330 millions subscribers in Europe, in June 2000 The NGN wave, ridden also by new entrant manufacturers è... associated with the regulatory and market evolution and pressure... copper local loop unbundling radio local loop unbundling UMTS standard favouring the third party service providers è... bring the missing business cases and make some TINA principles more up-to-date than ever : the business model, the need of a Service Architecture the use of the latest IT technologies and off-the-shelves environments

Various on-going activities such as Jain or Parlay (with TINA Access Session semantic for the Parlay framework) The result of this work has to be endorsed by bodies driven by specific business cases Parlay phase 2 adopted in UMTS for VHE

First step : For a service provider, to list the information manipulated by its services to be able to detect the potential concurrency access of various services on the same information. Second step : Build a consistent execution of the various services. Yet an open issue with some solutions to investigate.

Let us remind that TINA-C primary aim was R&D cooperation, i.e. collaborative assessment of technology innovation è Even if TINA is not a standard de facto, the Consortium has been particularly successful in anticipating, vulgarising, influencing, promoting concepts/ideas. è Since 1993, the telecommunications context has changed dramatically : IP, mobile, NGN. è The best TINA concepts are naturally turning into specifications and products in the bodies addressing specific market needs (3GPP, OMG, IETF, SoftSwitch, etc)
