However, we are not properly calling the
nr_ue_get_rach() function. The RA is being
properly initialized. In the nr_ue_get_rach()
the pRACH is not scheduled. Tried to add in
the scheduling of this, but it crashes here.
The other changes include revering the
nr_ue_get_rach() changes from previous commit.
Also, changed a few log levels and reverted
a previous change in the NR UE RRC layer that
was incorrect.
-User plane traffic validation with OAI UE and OAI CN:
-Downlink ping initiated from the CN is received at the IP interface of the UE. However it seems that there is some packet corruption preventing the generaration of ping reply.
-Uplink ping initiated from the UE reaches the OAI CN machine. However no ping reply is seen yet either.
Several places where memory ownership was changed
and the original owner was not set to NULL. Also,
the transaction_identifier is now based on the
received dl_dcch_msg in the LTE UE. Still need to
fix the t_id for the NR UE. Also added comments for
RACH procedure in NR UE.
This commit fixes a bug that makes the dataplane traffic of all the
emulated UEs to go through the interface of the first UE (oaitun_ue1).
The fix uses the last octet of the IP assigned to each UE to map it to its
UE_id, which is then used to get its RNTI and the correct PDCP queue.
For the emulator to work properly, the routing tables of the emulated UEs
must also be set. This patch introduces a script (setup_routes.sh) in
cmake_targets/tools that configures the routing tables. This script
must be run at the UE host machine once the UEs have successfully attached,
passing the number of emulated UEs as the argument. For example, in the
case of 16 emulated UEs, one must run "./setup_routes.sh 16".
At the moment, the NSA mode worked once, but shows
unpredictable behavior. Other times it does not work.
In this commit I added several LOG_A messages for NSA
mode. Also removed old comments that were added during
development. Lastly, more comments for all the hacks
have been added.
The eNB may only check for RRC_Complete in EPC
mode. Need to look at this further. Updated how
we pass the RRC_Complete msg from NR UE to LTE UE.
Need to still handle transaction_id from dl_dcch_msg
in the LTE UE and trans_id from nr_dl_msg.
