How to use micro controller control mobile send SMS?

[Gah Wah]

Hi everybody, I’m a college student currently working final year project but I have no idea and I'm looking for help !!!
I’m currently working on a RFID based vehicle tracking device, and I'll be using a gsm phone to send data via sms from the vehicle to another gsm phone. The question is , how can I interface the microcontroller unit to the gsm phone? , I’m planning to interface a 6150, is it possible??? ,and which is easier to deal with 6110 or 6150 ? and which microcontroller is prefered to use , and how can communicate with the phone through the microcontroller ? . I know it's too much to ask but I'm supposed to deliver my project within a month so I don't really have the time to study about all of this , please if anyone knows these stuff or at least somthing about it , please help me . thx for all in advance

Thanks,
