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
  • ur packet access networks would be connected to a consolidated

packet core network. The concept aims eventual all-IP migration

  • f our mobile network. The concept also includes fixed-mobile

network convergence.
