Hi Osmocom,
Do we have feature/functionality in OSMO-BSC similar to authorized-regex of OSMO-NITB
where a IMSI prefix or regex is used to determine if the subscriber is permitted to
register to the network or not. I've tried to looked at the osmo-bsc manual but I
haven't seen any configurations related to the said feature/functionality. I've
tried also the access-list configuration but I think it's no longer supported in
latest version.
Usually, the HLR (via MSC) determines whether a subscriber is allowed access to
a network, the BSC should have no say in this.
The IMSI regex in osmo-nitb was a highly non-standard way to scratch a very
specific itch, in the same way that osmo-nitb was maybe simpler to use, but
hardly possible to integrate with a standard core network.
So, no, there is no access management in osmo-bsc. In contrast, you need to add
each subscriber to the HLR database (e.g. osmo-hlr) so that a subscriber is
allowed to attach.
