However, when we free after we encode, fsanitize isnt happy.
Need to clean that up. Also, found an actual bug in LTE.
For the random value issue from fall 2020, we added a fix.
This fix uses ctxt and we were getting ctxt properly.
Lastly, we allocated some memory in processing of the
NR Meas report in the eNB.
At this point we are successfully able to build.
Additionally, we can run the scenario,
however, it does not pass. It seems that the gNB
is not connecting to the proxy correctly. Just
wanted to push the progress so far. FYI, the items
that had to be changed to correct the linking issues
were the following:
- mac_rrc_data_ind_ue vs. nr_mac_rrc_data_ind_ue
- rrc_data_req vs. nr_rrc_data_req
- mac_rrc_data_req_ue vs. nr_mac_rrc_data_req_ue
- rrc_data_req_ue vs. rrc_data_req_nr_ue
- rrc_data_req vs. nr_rrc_data_req
The listed functions should be declard in the LTE/NR
UE directory depending on the functionality. Several
were mixed. i.e.: LTE functions being called in NR UE.
Also, removing siWindowLength, siWindowLength_int,
SIBType, SIBPeriod, and siPeriod_int from the NR UE RRC.
These variable were not used in the NR UE and are defined
for LTE only.
Lastly, in the NR_IF_Module.c of the NR UE, the global
variable def_dci_pdu_rel15 is not accessible. Need to
revisit this. For not it is commented out.
Updated the configuration files. Added a sleep to
ensure that the LTE UE gets attached to the EPC
before the bearer is modified to be gNB. Updated
the ifconfig tunnel up command to be brought up
by the NR UE socket when in NSA mode. Lastly,
started the gNB PDCP layer in S1 mode.
1. If VNF is slower than PNF, next scheduling will be done after resync.
2. If VNF is unstable in slot progress, next scheduling will be done in next stable status.
3. SFN/SLOT indications are queued in nrUE.
4. get_queue is used instead of unquque for FIFO operation.
Once the LTE UE's tunnel interface with the EPC
is ready to be established, if we are in NSA mode,
we do not want to launch the tunnel interface
from the LTE UE side, but in the NR UE. Via itti_msgs
we send the string containing the tunnel interface
'up' command to the NR UE and bring it up from the NR UE.
It also includes the queuing development. The idea
is that the 5G Userplane messages will be filled
and configured the same as previous commit, but
the uplink messages will be queued and then sent to
the gNB during the correct slot. Still WIP.
