+**Step 11:** 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/ue.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.

+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"

+
+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 docker-compose file (/home/dco1020/oai-cn5g-fed/docker-compose/docker-compose-basic-nrf.yaml), shown in figure below.

+
+The UE parameters (figure below) must be equal to the OAI SMF parameters in the docker-compose file, as illustrated in the figure below.
+ - "DNN_NI0" refers to "dnn"
+ - "NSSAI_SST0" refers to "nssai_sst"
+ - "NSSAI_SD0" refers to "nssai_sd" (the "NSSAI_SD0" parameter is in hexadecimal, but in the "nssai_sd" parameter you have to use decimal values) 
+
+
+**Note:** In this version of the tutorial, the network slice is limited a just one slice (DNN=oai), because we do not use the NSSF (Network Slice Selection Function).
