Tests by Nokia Siemens Networks (NSN) have shown that new technology called Network Controlled Fast Dormancy (NCFD) makes the network and the handset work together to create the best conditions for smartphones to work quickly, yet have a long battery life and minimize network congestion, call drops etc.
The NSN conducted the above Test on latest Apple iPhone iOs 4.2 software device which supports this technology called Network Controlled Fast Dormancy.
The Smartphones connect constantly to the network, often driven by applications like FaceBook and others, or Online Gaming, checking emails, tweeting or status update via the smartphone. But this creates a huge amount of signaling as smartphones switch from an idle mode to an active state so that they can interact with the network, for example to get emails or pull in the latest tweets.
All this disconnecting and reconnecting takes time and can cause a frustratingly slow network response. On the other hand, leaving the smartphone in an active mode all the time drains the battery very quickly.
To overcome the problem NSN introduced a method that, instead of putting the handset into idle or keeping it always active, keeps the handset in an intermediate state. From here, a smartphone can wake up much more quickly and needs to send far fewer signals to and from the network to start a data connection. You get a fast network response and a longer battery life.
The new Apple software release supports this way of working on networks that have the technology implemented. World’s largest handset makers Nokia also implemented the technology in its smartphones earlier this year. So now the two handset makers that account for half of all new smartphones in the world contribute to an improved user experience and cost reduction for operators.
