HELP,How can I get the information of TCH from Q24PLUS!

I’m developing on Q24PLUS,and now I need to read the data of TCH and BCCH,I can get the BCCH by AT+CCED,but I can’t find any AT-COMMAND to read about it
Is there any way to get the data of TCH?
or is there any prouduct of WAVECOM could get it?

And I know I could get the data with MC35i,but I don’t want to use it.

THX a lot!
