.
When scenario is run manually:
In ue.cfg file, add for each UE, under ue_list:
• tun_setup_script: "ue-ifup"
• rue_addr: "192.168.1.100", where 192.168.1.100 is the remote PC IP address
.
Now, If you go back to remote PC:
• In LTE terminal you should see your UE using ue command
• In another shell run ip netns list command. You should see the networks namespace
created for each UE .See [Linux Network Namespaces], page 31, for more details
• You can run now any command within the UE Network Namespaces using command ip
netns ueX commandX. Example: ip netns exec ue1 ping 192.168.3.1
13.2 External application
You can replace predefined simulation by a custom application. For this, choose Application
in IP simulation list.
When started, the external application will fork a process and return its standard output and
error.
To handle dedicated application, please take a look at libsim_custom.js file in LTEWWW
component.
You can add specific result handler using tag for association.
Note that it requires associated UE to be configured in tunnel mode or with remote UE mode
and thus IP simulations can’t be mixed.
13.3 External SIM
External SIM card can be used using PCSC-Lite lib, which is supported on Amarisoft LTE UE
simulator
To do so :
• Install PCSC-Lite lib on your machine (pcsc-lite-devel)
• In ue.cfg file, under ue_list, set external_sim: true
• If several cards are used, set sim_reader_index. This is optional.
