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,
