Reply To: SMS, CS or PS ?


as i know, the decision wether SMS is sended over CS or PS is independant from RNC, and for each subs TS21GPRS and TS22GPRS should be assigned @ HLR side to decide wether send SMS over PS (through SGSN) or over CS (MSC). this is concept in 2G i think in 3G it should be same. anyway if the subs is not attached to the PS network even the SMS will be sent over MSC and so on.
