Reply To: ASN.1 database for GSM MAP and INAP 18th August 2004 at 11:49 #38753 KiranGuest Hi, Go to http://www.3gpp.org and pick up the 29.02 standerd(take the latest release from the folder). In that now a days they are providing the ASN file for MAP. You just club it with your TCAP asn file and compile it. It should work. Rgds.
