      trigger NR activation based on RRC measurements · 51ab31a3
      Cedric Roux authored
      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...

      hacks for NR · dd760540
      Cedric Roux authored
      - send RRC Connection Reconfiguration with dummy ENDC data by doing:
        telnet localhost 9001
        and press enter when the ENDC UE is connected to the eNB to send it

      x2ap/sctp: increase buffer size · 2421b71d
      Cedric Roux authored
      The 5G phone OPPO has a very big UE capability (> 2KB).
      
      We need bigger buffers to transfer this, especially in x2 handover.
      
      Also the sctp messages need a bigger buffer.
      
      Note: in sctp, we didn't check for partial messages, it's now
            done. When detected, we exit. To be redone differently
            if needed. (Look for "if (!(flags & MSG_EOR))".)

      cleanup: no variable definition in header file · 8a8fdd59
      Cedric Roux authored
      We declare variables in header files, we don't define them. So we need
      to use 'extern' in the header file and put the definition
      in some C file.

      hotfix: do not set s-Measure in measurement report configuration · e0eac2e3
      Cedric Roux authored
      The value was set to 20 which means -120 dB. Setting this value means
      that the UE reports an event only if the RSRP of the serving cell
      is lower than -120 dB.
      
      In the lab, we get values of around -70, and to go as low as -120
      means a very degraded environment. This is not practical.
      
      Let's disactivate the setting of this parameter for the moment so that
      the UE reports an event without taking into consideration the RSRP
      of the serving cell.
      
      With this hotfix, the X2 handover works much better.
