It still needs to be clarified<br>whether the new TLLI sent by osmo-sgsn is expected and test needs to be<br>fixed, or whether it's an sgsn bug.<br><br>Related: OS#3957, OS#4245<br>Change-Id: Id5554a91a8bda712e282c5a3e9e30fb0ca1ec0e8<br>---<br>M sgsn/SGSN_Tests.ttcn<br>M sgsn/expected-results.xml<br>2 files changed, 36 insertions(+), 0 deletions(-)<br><br></pre><pre style="font-family: monospace,monospace;
