Whitelisting/Blacklisiting of IMSI

Hi All, May we request on how to allow specific number of IMSI in OSMO-BSC? We tried the following using the REGEXP below, but all kinds of IMSIs are still able to camp. First try: auth policy regexp authorized-regexp ^12312\d{10}$ Second try: auth policy regexp authorized-regexp 12312\d{10} We also tried to used the access-list imsi-allow under BSC and then declare it under MSC configuration but still has the same behavior. All kinds of IMSIs are still allowed. First try: bsc access-list TEST imsi-allow ^12312\d{10}$ access-list-name TEST msc 0 access-list-name TEST Second try: bsc access-list TEST imsi-allow 12312\d{10} access-list-name TEST msc 0 access-list-name TEST We also tried to to used the access-list imsi-deny using the same regular expressions, unfortunately, still have the same outcome. All IMSIs are still allowed. First try: bsc access-list TEST imsi-deny ^12312\d{10}$ 16 16 access-list-name TEST msc 0 access-list-name TEST Second try: bsc access-list TEST imsi-deny ^12312\d{10}$ 16 16 access-list-name TEST msc 0 access-list-name TEST But using access-list imsi-deny to a specific IMSI, we successfully block it. Is there a way to block a number of different IMSIs only? What regular expression format is used by OSMO-BSC? Best Regard, Ron Menez ron.menez@entropysolution.com<mailto:ron.menez@entropysolution.com>
