+**Step 12:** Configure the IMSI, Permanent Key and OPC
+
+This part you will configure the UE parameters. The UE parameters file is /home/dco1020/openairinterface5g/targets/PROJECTS/GENERIC-NR-5GC/CONF/ue2.conf. The first three lines of the file are composed by the IMSI, Permanent Key and OPC, as shown in figure below. You will configure these parameters.

+
+You need to check in the docker-compose file (/home/dco1020/oai-cn5g-fed/docker-compose/database/oai_db2.sql) which SQL file the core is using. See figure below. 
+
+Important: The IMSI must be different between the EUs !

+
+Verify/change the parameters in UE file (/home/dco1020/openairinterface5g/targets/PROJECTS/GENERIC-NR-5GC/CONF/ue.conf) according to the SQL file illustrated in figure below. The parameters are:
+ - "ueid" refers to "imsi"
+ - "encPermanentKey" refers to "key"
+ - "encOpcKey" refers to "opc

+
+To open Docker Composer file, type:
+
+gedit /home/dco1020/oai-cn5g-fed/docker-compose/docker-compose-slicing-basic-nrf.yaml
+
+To see sqlFile, type in a terninal.
+
+gedit /home/dco1020/oai-cn5g-fed/docker-compose/database/oai_db2.sql
+
+Or use a SQLLite database visualizer like DB Browser (to install: sudo apt install sqlitebrowser -y).
+
+The last three lines of the file are composed of DNN (Data Network Name), N-SSAI SST (Network Slice Selection Assistance Information Slice/Service Type), N-SSAI SD (Network Slice Selection Assistance Information Slice/Service Type). To configure these parameters you will explore the configuration files for each slice, in this case here, we are going to configure the UE for the slice 1 (/home/dco1020/oai-cn5g-fed/docker-compose/conf/slicing_slice1_config.yaml), shown in figure below.

+
+The UE parameters (figure below) must be equal to the slice 1 configuration file parameters in the template, as illustrated in the figure below.
