UEsim LTE Multi UE
This tutorial is to show how to simulate multiple UEs with a single UEsim. For the simplicity, I am simulating only 5 UEs but you can simulate maximum of 500 or 1000 UEs with single Amari UEsim
For further details of the specification of AMARI UE Simbox Series, refer to this product datasheet.

Key Configuration Parameters
Followings are important configuration parameters for this tutorial. You may click on the items for the descriptions from Amarisoft documents.
I used the ue.default-multi-ue.cfg which is copied and modified from ue.default.cfg (LTE default configuration).
I used the enb.default.cfg (LTE default configuration).
I used the mme-ims-multi-ue.cfg which is copied and modeified from mme-ims.cfg
In the mme-ims-multi-ue.cfg, I changed the configuration so that ue_db-ims-multi-ue.cfg is used on Callbox.
In this tutorial, following SIM information will be used within ue_db-ims-multi-ue.cfg. Make it sure to configure the same parameters on UE side as well.
In ue.default-multi-ue.cfg on UEsim, Make it sure that imsi and K value in this file matches the value on enb side shown in previous slide
Following is the configuration in enb.default.cfg on Callbox
This is optional. In enb.default.cfg, I made a small change as shown below.
Following is the configuration in ue.default-multi-ue.cfg on UE sim
Perform the test
Start trace logging on Callbox
Power on UE on UE sim
Then you see following traces on Callbox and confirm all the UEs get attached
You can check the list of all the UE status with 'ue' command on UE sim
You can check the list of all the UE status with 'ue' command on (enb) on Callbox
You can check the list of all the UE connected to MME with 'ue' command on (mme) on Callbox
You may try ping from Callbox to all of the UEs
I would not go through all the log since this would just be the repetition of basic LTE attach procedure. The only thing that I want to highlight is the Attach Request from UE sim log showing different IMSI values for each UE as shown below.
