E2E Flows

E2 UE Attach Procedure

















The CU stub and RIC stub is also used in the O-DU-high and O-DU-low integrated flow

This page describes running O-DU High using test stubs, namely CU Stub and RIC Stub. O-DU High also uses Phy Stub in the absence of O-DU Low. However, Phy Stub is built as a part of the O-DU High image itself.

Execution of below steps yields successful UE Attach procedure and message exchanges required for Traffic Steering use-case on the E2 interface. These can be verified on wireshark by capturing SCTP packets.

  1. Prepare environment

    sudo apt-get install libpcap-dev libsctp-dev

  2. Cloning code

    mkdir odu_high cd odu_high git clone "https://gerrit.o-ran-sc.org/r/o-du/l2"

  3. Compilation of O-DU

    cd odu_high/l2/build/odu make clean_odu odu MACHINE=BIT64 MODE=FDD

  4. Compilation of CU Stub

    cd odu_high/l2/build/odu make clean_cu cu_stub NODE=TEST_STUB MACHINE=BIT64 MODE=FDD

  5. Compilation of RIC Stub

    cd odu_high/l2/build/odu make clean_ric ric_stub NODE=TEST_STUB MACHINE=BIT64 MODE=FDD

  6. Execution - Assign IP addresses

    ifconfig <interface name>:ODU “192.168.130.81” ifconfig <interface name>:CU_STUB “192.168.130.82” ifconfig <interface name>:RIC_STUB “192.168.130.80”

  7. Running CU Stub

    cd odu_high/l2/bin/cu_stub sudo ./cu_stub

  8. Running RIC Stub

  9. cd odu_high/l2/bin/ric_stub sudo ./ric_stub

  10. Running O-DU

    cd odu_high/l2/bin/odu sudo ./odu

    Note:

    1. Each of the above binaries must be run in separate terminals

    2. CU Stub and RIC Stub images must be run before O-DU image.
