Hello,
Is there a way in openBSC to know if a certain phone that previously connected to my BTS
is still connected at a given time ?

In OpenBSC not really, the subscription status is typically in the MSC and/or
HLR; so if you're using OsmoNITB you can query the subscriber's LAC on the VTY,
or use the CTRL command 'subscriber-list-active-v1'.
If you're using OpenBSC alone, there's no way AFAIK. It only sees a subscriber
when it is actually actively sending/receiving right at this moment.

You can use the location update timestamp in the HLR. The MS will RACH periodically based
on the value of the T3212 timer. This is configurable to multiples of 6 minutes with 6
being the minimum. If a phone hasn't updates it's location after that interval has
passed you can assume it's not connected

I would have referred you to the user manual
http://ftp.osmocom.org/docs/latest/osmonitb-usermanual.pdf
but must notice that it isn't very helpful in describing this CTRL cmd.
It returns subscribers that are attached, i.e. no active call or such needs to
be going on to be listed.
Might also include a subscriber slightly too soon, see
http://osmocom.org/issues/2285
For manual access, using the vty 'show subscriber imsi 12345654321' might be
easier (a LAC=0 means not attached).
