Firstly, call oaienv.bash located in oEPC/trunk folder. Example: ~/BS-openAir4G/oEPC/trunk$ bash oaienv.bash

Use build_oai.bash script at ~/BS-openAir4G/oEPC/trunk/targets folder to compile and install oaisim. Verify at ~/BS-openAir4G/oEPC/trunk/targets/SIMU/USER if the executable is generated. Example: ~/BS-openAir4G/oEPC/trunk/targets$ bash build_oai.bash -l ENB -t OAISIM -w NONE

Emulate one BS and one Virtual UE usingh the script 'start_enb_and_ue_virt.bash' located at '~/BS-openAir4G/oEPC/trunk/targets/PROJECTS/GENERIC-LTE-EPC' Example: ~/BS-openAir4G/oEPC/trunk/targets/PROJECTS/GENERIC-LTE-EPC$ bash start_enb_and_ue_virt.bash te2

if te2 is a folder that contains configuration file for eNB (enb.callison.conf in this case)
