Already read 4 pages of this thread. Thanks to Pix and Bijoy ‘s inform.
Btw, in my oper has a problem: Currently using DTM (on BSc Ericsson) and when PS handover performed (moving..), the MS is attached to SGSN and MSC with different cell, and MS cannot make a PS call :(. (b/c i know DTM is well done only when MS is served in the same ARFCN).
Could u pls explain it? Thanks so much.
