Hi
GPRS connection and PDP context activation when you already connected to SGSN and GGSN and have the access IP. and session means when already you have transfering it is the same as making call and when you , Billing will be start when you have TBF( data block transfer).
When you transfer from SGSN to other SGSN all data,signalling by GTP(GPRS tunnel protocol to other SGSN) you can check for GTP on net there are alot of discussion about it
