Partially yes. I'm talking about GSM08.08 "ยง 3.2.1.32 COMPLETE LAYER 3

I would like to implement the following.
- Remove the refcount from lchan
- Replace it with the "transaction" concept. On certain 04.08
messgaes (e.g. paging response, various MM messages) open a transaction
from BSC to MSC code. The channel is bound to the transaction.
Are you talking about the transaction in transaction.c ?
Because for SMS for examples, we re-use the same lchan for consecutive
transactions when delivering multiple SMS back to back and your
approach would make that impossible if I understand correctly ?
Well, it is up to the MSC to decide when to close the "transaction"/SCCP
connection. So if the MSC policy is to send multiple SMS it will still work.
The general change is that the MSC is completely controlling the lchan
lifetime. If the radio resource is freed, but the MSC still occupies the
channel it will not be reused.
