An NR-capable UE will transmit some NR measurements.
Once received, the whole process on nr-cell addition is started.
It will fail quickly.
Many things are still missing.
What is not handled properly with this commit:
- in x2ap_eNB_handle_sgNB_add_req we hardcode the gNB ID
- nr triggering is done if we receive a measurement but this measurement is
not analyzed at all
- no timers (T_dc_overall, T_dc_prep) and as is the code fails and then the
next triggering after UE reconnection will not work (x2 ID are not well
handled here and there in the code)
Note also that the gNB part has not been looked at all for this commit.
This is work in progress...
This commit introduces X2AP timers (t_reloc_prep, tx2_reloc_overall).
You need to set the values in the configuration file.
X2AP can be enabled or disabled in the configuration file too (disabled
by default).
Some deadcode was removed.
Some deadcode was removed.
The implementation of the ID management is not finished.
It will only work if the handover is successful. No error
recovery has been done. For error recovery, we need to
implement the X2AP timers. As it is, in case of error, an ID
might very well never be released.
It has been tested with 1 and 2 UEs doing handover more or less
at the same time.
- manage target eNB based on target cell id received by measurement report
for Handover Request
- manage source eNB based on association id for Handover Request Ack
- use only x2ap instance and not x2ap data instance points to x2ap instance
