Basestation to mobile question!

Archived from groups: alt.cellular.gsm (More info?)

Hello,
Is it possible in GSM or in 3GPP standards for a cellular base station to
directly upload code to mobile handsets? Are there examples of such codes or
applications of this sort (both current and planned) ? One example can be
upgrades to a phone's service or an application.
I am looking for some information on how this is handled at a protocol or
even at the OS level. Any help will be highly appreciated!
Thanks,

For what possible reason could a base station have to send any "code" to
any handset? Any "code" (whatever that is) would need to be initiated
by the handset user, and it won't be provided by any base station
either. A base station is a radio controller, not a content provider.

You wouldn't be fishing for how to create a virus, would you?
No, of course not ...

There are ways of uploading Java apps OTA (over the air) to Java
capable phones, Symbian apps to Symbian phones and, at phenomenal
expense and only with carriers consent, BREW apps to BREW phones.
There are various security measures which can impede this.

Your exercise for the day is to google combinations of OTA, Java,
Symbian and Brew ... and, for some cheap, hackerish thrills, you could
throw in 'firmware' as well.

Whoo Hoo

btw, just to make it clear...no, this is not a homework assignment! i am
done with my courses...thank god! i am a final-year phd student in computer
science and engineering at michigan - i have been working on some algorithms
on mobile security in my spare time (huh!)
