Description

Let's implement a minimalistic SMLC which
  • interfaces with the BSC via the Lb interface (BSSMAP-LE via connection-oriented SCCP)
  • supports only the TA based positioning according to TS 43.059 section 9.3

The SMLC should come with a TTCN3 test suite.


Checklist

  • TTCN3 infrastructure to implement Lb interface in terster
  • TTCN3 test suite emulating BSC towards SMLC
  • actual osmo-smlc implementation for (at least now) TA based positioning

Skeleton of osmo-smlc is available at https://gerrit.osmocom.org/c/osmo-smlc/+/19779 - it basically does nothing but bind to the SMLC SCCP SSN + Point Code + expose VTY + CTRL on the newly-registred ports.

The git repo on gerrit + gitolite mirror has been created, as has the coresponding redmine project into which this issue has been moved.
