SGSN Number for a outbound roamer.

Hi Thyraell,Thank you for your response.Could you pls confirm is it a MAP message which can be triggered (as a stand alone MAP message) towards to HLR so that the HLR would provide the currently attached SGSN number towards to requester as a part of response. (I mean retrieving foriegn/outbound roamer's SGSN number from HLR by firing a MAP message to HLR)Pls help to send the full trace so that it would give more clarity.Thanks a lot.

GPRS attach message is MAP

GPRS attach message is MAP message sent from SGSN toward HLR for GPRS Location update. same like SAI message sent from MSC/VLR toward HLR for location update in VLR. the response of "GPRS attach" from HLR number will not include the information of current SGSN.here is the trace file : http://www.filesonic.com/file/3862641625/thyrael_trace.zipyou can find it on folder gprs attach, i also included several guidelines for GPRS roaming in the files.hope it helps

 Hi sri_telecom, I am not sure but I guess SRI/SRI_for_SM query to HLR can also give the SGSN address.BR//sama
