ITU-T o KDDI plans to complete all-IP migration of our fixed-line telephony network by March, 2008. The plan also includes the introduction of “ Metal-Plus” , hybrid IP telephony system. KDDI disclosed “ Ultra-3G” concept, according to which, a variety of o our packet access networks would be connected to a consolidated packet core network. The concept aims eventual all-IP migration of our mobile network. The concept also includes fixed-mobile network convergence.
