pespin has submitted this change.

S1AP_Emulation: Fix building security headers for Integrity and Ciphering The fact that the network instructs the UE to use EEA0 encryption (null algo) doesn't mean the UE should mark the NAS frames in the security header as non-ciphered. They need to be marked as IP+ciphered in the outer header, and as plain in the inner one. Now TTCN3 behaves like a UE recorded while executing a similar test case. Moreover, wireshark is now happy decoding the messages.

The following approvals got outdated and were removed: Code-Review+1 by daniel Change subject: mme: expect authentication during 2g->4G TAU procedure ...................................................................... mme: expect authentication during 2g->4G TAU procedure If TAU happens without an existing security context, network for sure wants to authenticate the UE. This is the scenario being tested here. If there was a security context (eg. from a previous 4G Attach), then it's up to the network to decide (or be capable) to implicitly authenticate the UE.
