GSM/GPRS/UMTS Communication

Hi,

I am trying to develop an application that would allow on-air encryption
of the voice data (similar to voice privacy option that's in some of the
mobile handsets).

The communication channels that I am looking at are GSM, GPRS and UMTS.

As an example, if I talk over, say, GSM channel - the data-in-air must
be encrypted. Similarly, if I send an SMS, the floating-data must be
encrypted.

However, to start with, I do not know anything about how it can be
programmed in Windows CE. I am, actually, working on Windows Mobile
profile... however, would prefer to be on Windows CE (4.x, 5.x) including
also the PocketPC and Smartphone.

Any pointers would be very very helpful.

not really in my league, but it sounds like you are trying to do this:
http://www.securegsm.com/home.php

you might want to have a look into the ril.dll (radio interface layer).
it's not public documented, so this might be tricky.

When the news reporter said "Shopkeepers are opening their doors
bringing out blankets and cups of tea" I just smiled. It's like yes.
That's Britain for you. Tea solves everything.

Thanks riki,

Let me have a look into the RIL part. I've got hold of a RIL White Paper
from MS (June 2004). Let me see if I am able to get anything there...

Thanks for the SecureGSM pointer as well.

I think I am getting into some good league :)

Hi,
As per my knowledge MS provides RIL/RIL PROXY driver only on Windows
Mobile, I have not come across and RIL driver on WinCE till now. If
you're working on WM then you look into help (document) of the same.

I'm came across this thread because I'm after information on answering an
incoming data call on a QTEK 9000 WM5.0 Pocket PC.
Has anyone got any sample code that could do this?

I'm trying to write a dial-in bulletin board program for Pocket PC.

Many thanks.
Kind regards,
Richard Twyning
