      x2ap: timers, cleanup · 9456fe58
      Cedric Roux authored
      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.

      minor fixes for x2 + modify conf files · 3b3b9718
      Konstantinos Alexandris authored
      The configuration file has now to contain ENB_IPV4_ADDRESS_FOR_X2C and
      ENB_PORT_FOR_X2C in the NETWORK_INTERFACES section.
      
      For example:
      
          NETWORK_INTERFACES :
          {
              ENB_INTERFACE_NAME_FOR_S1_MME            = "eth0";
              ENB_IPV4_ADDRESS_FOR_S1_MME              = "192.168.12.111/24";
              ENB_INTERFACE_NAME_FOR_S1U               = "eth0";
              ENB_IPV4_ADDRESS_FOR_S1U                 = "192.168.12.111/24";
              ENB_PORT_FOR_S1U                         = 2152; # Spec 2152
      
              ENB_IPV4_ADDRESS_FOR_X2C                 = "192.168.12.111/24";
              ENB_PORT_FOR_X2C                         = 36422; # Spec 36422
          };

      set value of pucch_n1_AN to 0 everywhere by default · cce51f69
      Cedric Roux authored
      Since now pucch_n1_AN is taken from the configuration file,
      it has to be set to 0. Value 32 will not work well, at least
      in FDD. This has to be handled properly at some point
      (do not use uplink resource blocks used by PUCCH for PUSCH).

      import work from the branch nfapi-L2-emulator to merge it to develop · f254107b
      Cedric Roux authored
      It was not possible to merge the branch directly, because the
      history of this branch contains files that cannot be in the
      repository, namely wireshark from Cisco work on nFAPI.
      
      As for Cisco work on nFAPI, a special commit containing all the
      work is thus created.
      
      Below is the output of the command:
      git log --graph 184d51c6..61276d87
      
      184d51c6 is the commit ID of the develop
      branch prior to the merge.
      
      61276d87 is the commit ID of the
      nfapi-L2-emulator branch prior to the merge.
      
      The commit 61276d87 (and all its
      history) will be removed from the main OAI repository. It is
      present in the internal OAI repository for those who have access
      to it.
      
      There was also some cleanup done on the code.
      
      Some changes were necessary to have the eNB functional. They may have an
      impact on the FAPI ...

      bugfix: fix eNB name in configuration files · 11fe5f97
      Cedric Roux authored
      '_' is not a valid character.
      
      S1AP specs say:
      
          ENBname ::= PrintableString (SIZE (1..150,...))
      
      And X.680 (08/2015) 41.4 table 10 lists the valid characters for
      PrintableString. '_' is not there. We replace by '-' which is there.
      
      Connection of eNB to ppenair-cn has not been tested. There is no reason
      why it would fail.

      Fix NFAPI integration · 922b5b59
      Cedric Roux authored
      This commit fixes issues introduced by the previous commit.
      
      Summary of work:
      - cleanup:
        - fix LOG_XX to be less verbose
        - fix cmake_targets/CMakeLists.txt
        - fix oaienv
        - remove dead code
      - bug fixes:
        - in openair1/SCHED/fapi_l1.c we had:
            eNB->pdcch_vars[subframe&1].num_dci           = number_dci;
          should be:
            eNB->pdcch_vars[subframe&1].num_dci           = 0;
          This bug let the PHY send more DCIs than what should have been
          sent because num_dci is incremented later on in the code.
          This fix may be a problem for fapi mode, to be checked.
        - add new T VCD traces
        - revert openair1/PHY/TOOLS/file_output.c to 'develop' version
        - remove thread_id in logRecord/logRecord_mt
        - revert (and adapt) configuration files
        - be careful when doing frame++, we need to % 1024
        - revert target_rx_power in openair2/LAYER2/MAC/eNB_scheduler_ulsch.c
      - NFAPI:
        - the open-nFAPI code has been included in the repository. See nfapi/README.
          Maybe we should "git clone" the Cisco repository instead. We have to be
          careful of availability though.
      
      What has been tested:
      - monolithic eNB FDD 5/10MHz with one UE, iperf UDP/TCP uplink/downlink
      
      Anything else may fail to work, especially the FAPI mode, which has not
      been tested at all.

      import NFAPI work from David Price from Cisco (non-working commit, do not use it) · 7757b9e7
      Cedric Roux authored
      It has been chosen to not include the full history of commits
      from David. He included a binary version of wireshark, probably
      a modified one that understands NFAPI. Wireshark is released under
      the GPL license, we cannot include it in the repository. We could
      have done a next commit to remove this binary. But then it would
      still be present in the history of commits, which may not be allowed.
      And it would take space on disk. We could edit the history to remove
      wireshark entirely. But this operation is too complicated.
      
      There was also a pcap capture file, which has nothing to do in
      the history of commits and would take space on disk. There again,
      it's too difficult to edit the history to remove it.
      
      There was a file .gitignore that was also removed.
      
      The original history can be found on David's repository:
      https://gitlab.eurecom.fr/daveprice/openairinterface5g/
      The branch is: nfapi-ru-rau-split.
      
      A copy of that branch has been ...
