setup OAI-USRP

In my P720 workstation,I have made some work about OAI and USRP B210 case, the “Basic-sim” is work well….but we need to let mobile find my LTE cell boardcast in B210.

These are my work log.

in my P720 server, ubuntu1604

  1. open “Virtual Machine manager”, use EPC vm to run : sudo srsepc
    if you want to modify the configuration ,open the file “~/.config/srslte/epc.conf”
  2. RUN USRP board, in local machine to run:
    a.build: “./build_oai -w USRP -x –eNB”
    b.run eNB: “ENODEB=1 sudo -E ./lte-softmodem -O $OPENAIR_HOME/ci-scripts/conf_files/enb.band13.tm1.25PRB.usrpb210.conf -d”
    c.now, we have modify the USRPB210 conf ,DL freq is 751Mhz, OK.
  3. we want to run basic-sim between eNB and UE without USRP.
    a.rebuild: “./build_oai –eNB –UE”
    b.open eNB software:
    $ source oaienv
    $ cd cmake_targets/lte_build_oai/build
    $ sudo ENODEB=1 sudo -E ./lte-softmodem -O $OPENAIR_HOME/ci-scripts/conf_files/lte-fdd-basic-sim.conf –basicsim c.open UE software:
    $ source oaienv

#Edit openair3/NAS/TOOLS/ue_eurecom_test_sfr.conf

$ cd cmake_targets/lte_build_oai/build
$ ../../nas_sim_tools/build/conf2uedata -c $OPENAIR_HOME/openair3/NAS/TOOLS/ue_eurecom_test_sfr.conf -o .
$ sudo -E ./lte-uesoftmodem -C 2625000000 -r 25 –ue-rxgain 140 –basicsim
now UE get new ip of oaitun_ue1:
—oaitun_ue1 Link encap:UNSPEC HWaddr 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00

we can ping epc ip”172.16.0.1″ address from UE ip”172.16.0.2″.
ok…..
