1. Introduction
Detail the approach of steps for xFAPI, OSC-DU & FlexRAN deployment
1.1) Description:
This installation and execution guide provides detailed steps and troubleshooting tips for running xFAPI in conjunction with FlexRAN, OSC DU-High, and CU_stub.
1.2) System topology
2. Minimum Requirements
Detail the hardware and software requirements necessary for the installation
...
Cores: 4th Gen N series Intel Cpu with Vran boost
RAM: 256Gi Memory
3. Installation
Step-by-step instructions for deployment
...
Locate the Zip Folder:
mv /path/to/xfapi.zip /desired/deployment/path/
Unzip the project :
cd /desired/deployment/path/
unzip xfapi.zip
4. Post-Installation Verification
Outline how to verify that the installation was successful.
We can validate the installation by these points, we should have the required binaries at these places :
...
4.5) cu_stub binary [cu_stub] at :
<OSC_DU_high_directory>/bin/odu/odu
5. Setting Up The Environment
Step up the env. variables for FlexRAN :
...
ifconfig lo:CU_STUB "192.168.130.82"
6. Executing Stack
The sequence of execution of binaries is:
...
cd <OSC_DU_high_directory>/bin/odu/odu
./odu
7. Troubleshooting
Provide common issues and their solutions.
Issue 1: Error in loading shared libraries while executing the FlexRAN
Solution: cd phy/source setupenv.sh
Issue 2: Parsing error in FlexRAN
Solution: Update the <version> in phycfg_xran.cfg file, located at :FlexRAN/l1/bin/nr5g/gnb/l1/phycfg_xran.xml
Issue 3: Error in loading xsm lib in xFAPI
Solution: cd <xfapi directory>source loadenvvar.sh
Issue 4: Failed to bind the socket while executing the cu_stub
Solution: Configure the virtual IP addressesifconfig lo:ODU "192.168.130.81"
ifconfig lo:CU_STUB "192.168.130.82"
NOTE: Log files can be generated in xFAPI for detailed analysis. Both horizontal and vertical logging levels can be configured in the xfapi_cfg.cfg file.
