Please be more specific what is the exact behaviour you would like. * The GSM side should reject all location updates, but only GPRS LU + ATTACH should work? This should be possible by having no subscribers in your NITB HLR and white-listing them in the SGSN ACL. However, 99% of all MS that I've seen will attempt a GSM LU before doing a GPRS LU, and if they get rejected on GSM, they will not try to register on GSM. Only some very few MS (like certain cellular modems for M2M applications) can be configured to only attach on GPRS without performing a GSM LU first. * GSM LU should work, but all calls and SMS shall be rejected This is not possible currently, it would require some smaller modifications/extensions to the code. Would fit quite easily into the new OsmoMSC + OsmoHLR model, where the HLR could be extended with subscription information for all individual teleservices. -- - Harald Welte <laforge at gnumonks.org> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."
