Feature #2513

pick a different MCC+MNC+LAC for each test

Updated about 6 years ago.
Description
To make sure that modems don't assume they are already registered, we want to change at least each test run's LAC. This should happen in the way that we hand out MSISDNs for each test and modem.

I pushed a patch series to use a unique LAC for every BTS resource created:
remote: New Changes:
remote: https://gerrit.osmocom.org/4703 resource: Refactor next_msisdn to be more generic
remote: https://gerrit.osmocom.org/4704 Use unique incrementing value for BTS LAC
ofono shows in PropertyChanged signals when registered how the LocationAreaCode is different every test, but the "CellId" is always 0, it may be a good idea to investigate where does that field come from and may be worht changing it every time too.

That's the CI aka bts->cell_identity aka vty 'bts' / 'cell_identity <0-65535>' value

The Cell ID should be the one configured as cell_id for that given BTS inside the BSC configuration file. If
it is not, then it gets lost somewhere, likely on the modem/ofono side.
Every Cell inside a LAC must have a different cell_id. cell_id across LAC
must not be unique, but often are in practise based on operator procedures.
