PS1, Line 338: static void bsc_paging_T3113_expired(void *data)
> I'm a bit lost here. […]
Yes, there is an existing code path to expire the paging per BTS, but not per BSC.
Expiring per BTS also has its own counter.

However, the per-BTS counter is not suitable for attTransOfPagingMessagesPerBSC (3GPP TS 52.402 § C.3.2.4).

When paging one subscriber with 1 BSC that has 3 BTS attached, and the paging fails for all 3 BTS, we need this new per BSC counter to know that 1 paging failed (and not 3, as one would get by summarizing the per-BTS counters).

The TTCN-3 test has both the BTS and BSC paging:expired counters, might help to illustrate this too: https://gerrit.osmocom.org/c/osmo-ttcn3-hacks/+/26387
