From 81d7c14756ee17c2748c3d34a198c640655fd0c6 Mon Sep 17 00:00:00 2001 From: Jacob Erlbeck Date: Thu, 24 Oct 2013 01:33:22 +0200 Subject: gb: Add test cases for NS RESET procedures Add a test handling proper and mismatching RESETs. The latter may occur, when ports change within a NS-VC without the SGSN getting notice. This tests for the behavior of the NS protocol stack for RESET and RESET_ACK messages which changing/invalid NSEI and NSVCI like it is being described in 3GPP TS 08.16, 7.3.1.
