Storage requirements and capabilities will dramatically increase in both devices and networks. Some key network characteristics also must be available to devices connected to the fixed network. The evolution of connected home networks along with various applications, such as interactive TV, games, music downloads, shopping and home security will require some of the characteristics delivered by IMS (e.g. quality of service, user management, charging and security).


The above describes the current situation in the standards area for fixed and mobile networks, and a variety of access alternatives for both types of networks. It also discusses recent developments that will enable fixed - mobile convergence in the future, namely the UMA initiative. This initiative is currently positioned as GAN in 3GPP and the IMS architecture as defined in the 3GPP R5 and R6 and 3GPP2 MMD specifications. There are similar activities for NGN in ETSI TISPAN standardization activities and the ITU's NGN Focus Group. The target network architecture is then shown with numerous access methods and services built on top of IP control intelligence.

Finally, IP-based traffic management is a vital component for the success of a multiservice and converged network. And there is a need for QoS mapping/interworking between different access networks and IP core network.
