lIdentification Request (P-TMSI, old RAI, old P-TMSI Signature )/ Identification Response (IMSI, Authentication Triplets or Authentication Quintets )
 
pIf the MS, at GPRS Attach, identifies itself with P-TMSI and its old RAI and neither of them belongs to the routing area in the charge of the new SGSN, the new SGSN shall in this case send the Identification Request message to an SGSN based on the old RAI, as usual. The old SGSN returns the users IMSI.

nRequest:
New SGSN->Old SGSN
nResponse:
Old SGSN->New SGSN
 
pTrigger condition:
 
nP-TMSI-based attachment is initiated and the MS sends the RAI information of the old SGSN.
