This might not be the best matching forum here. I recommend to search for AT-supporting public forums, i.e.:

As rkopsch suggests, this has nothing to do with ARM or Keil.
Your modem neither knows nor cares what microcontroller you are using - or, indeed, that you're using a microcontroller at all.
You will need to read the AT Commands documentation for the particular modem you are using, to see if it has a specific AT Command and/or command option(s) to do what you want.
If there is no dedicated command, then you are going to have to have your program go through the all messages, and pick out only the ones you require.

It's not a 'C' language thing; this is just software design - it would be the same in any language.
