(keitai-l) Re: i-mode is NOT always on

I may be totally of the mark, but the understanding of the matter that I
have gathered is the following:

With i-Mode technology there is an unambiguous way of addressing the end
client (phone) that the services (such as for instance e-mail service) can
use. This eliminates the need to dial-up and authenticate which are, in
effect, the cumbersome elements the lack of success of WAP-based in Europe
is partially blamed for. In other words a packet may be addressed to a
particular subscriber and as soon as the subscriber is available on the air
interface, the packet gets sent, possibly triggering some functions on the
client (blinking icon etc).

So maybe not always on, but always addressable is the right definition.

Regards,
Gennady

A very thorough analysis, thanks. In that light, how do we explain the
following:

my phone is 'off' the network (the i is not blinking)
someone sends me an email and immediately my phone connects (i starts
blinking) and the mail is delivered.

Exactly how is the handset getting notified of the incoming mail if it's
not yet on the network?

I am confused.
