RE: iMode network infra

Hi Eddie,
To give a quick answer to your question, GPRS is transparent to Kannel. It
only affects the phone's connection to the internet so this is supported by
Kannel. The connection is only brought up when data needs to be sent but the
phone can keep an IP address allocation for longer periods of time, giving
the impression of an "always on" connection.

MMS is basically an extension to WAP to allow new types of content to be
delivered to the mobile, such as SMILE scripts, animated pictures and
sounds. I am not sure about the level of support currently in Kannel but I'm
sure someone will be along with the answer soon.

I-mode is a different service offering similar functionality to WAP but
without the intervening protocol stack that WAP uses between the content
server and the phone. The phone talks to a HTTP server using only an HTTP
proxy rather than a WAP gateway. The phone's browser understands a subset of
HTML which it receives from the proxy server directly. There is no
translation of the HTML into more compact notation and no I-mode specific
security options as there are with WAP. To support I-mode you just need to
replace Kannel with a HTTP proxy.

Hope this helps
