Can somebody comment if my thoughts are correct?
People claim that i-mode is always on. This is technically speaking
incorrect and gives the readers outside Japan a wrong impression on the
capabilities of i-mode.
To verify please do the following experiment.
Check the i-icon on your phone. If not connected to the i-mode network
(connection OFF, but able to connect to i-mode packet switched network),
the i-icon is not blinking. When you connect to the i-mode network, it
takes, depending on the time of the day, between 1 second (early in the
morning) and 5 seconds (around 11pm). Once the connection is established,
the i-icon is blinking meaning the connection is ON. If no traffic is send
or received for a period of 3-4 minutes, the connection is automatically
finished and the i-icon stops blinking. The connection is OFF.
Based on the network architecture as published last year in Nikkei
Communications and this experiment, i-mode makes use of a hybrid solution,
circuit switched until the M-SCP component in the network and
packet-switched (called the PCD-P network) higher up in the network.
