set your MySQL password and remember it!
Answer yes to install: freeDiameter 1.2.0
phpmyadminn choose apache, configure database for phpmyadmin with
dbconfig-common: yes, password: same as MySQL for simplicity
Install 3PP SW for mme and spgw
# ./build_mme -i
Do you want to install freeDiameter 1.2.0: no
Do you want to install asn1c rev 1516 patched? : no
Do you want to install libgtpnl ? : yes
wireshark permissions: as you prefer
# ./build_spgw -i
Do you want to install libgtpnl ? : no
Compile the EPC nodes
# cd ~/openair-cn; source oaienv; cd scripts
# ./build_hss
# ./build_mme
# ./build_spgw
# nano openairinterface5g/targets/PROJECTS/GENERIC-LTE-EPC/CONF/enb.band7.tm1.25PRB.lmssdr.conf

Change tx_gain 127 and rx_gain 160 je careful i am not sure it is necessary and it is max values
Change to this
////////// MME parameters:
mme_ip_address = ( { ipv4 = “127.0.0.20”;
ipv6 = “192:168:30::17”;
active = “yes”;
preference = “ipv4”;
}
);
NETWORK_INTERFACES :
{
ENB_INTERFACE_NAME_FOR_S1_MME = “lo”;
ENB_IPV4_ADDRESS_FOR_S1_MME = “127.0.0.10/8”;
ENB_INTERFACE_NAME_FOR_S1U = “lo”;
ENB_IPV4_ADDRESS_FOR_S1U = “127.0.0.10/8”;
ENB_PORT_FOR_S1U = 2152; # Spec 2152
};
And this
In the eNB config file, you need also to set the MCC and MNC as per your SIM card:
tracking_area_code = “1”;
mobile_country_code = “208”;
mobile_network_code = “92”;
Install this configuration for EPC
For the EPC, we install in OAI default directory: /usr/local/etc/oai
# sudo mkdir -p /usr/local/etc/oai
# sudo cp -rp ~/opencells-mods/config_epc/* /usr/local/etc/oai
# cd ~/openair-cn; source oaienv; cd scripts
# ./check_hss_s6a_certificate /usr/local/etc/oai/freeDiameter hss.OpenAir5G.Alliance
# ./check_mme_s6a_certificate /usr/local/etc/oai/freeDiameter mme.OpenAir5G.Alliance

Only the SGi output to internet need to be configured.
# nano /usr/local/etc/oai/spgw.conf
your should set the interface that is connected to Internet, and,
to tell to the PGW to implement NAPT for the UE traffic
PGW_INTERFACE_NAME_FOR_SGI = “wlp2s0”;
PGW_MASQUERADE_SGI = “yes”;
Change wlp2s0 with your interface
For the SIM card, you’ll have more to do:
SIM MCC/MNC should be duplicated in a couple of files
eNB: See above in eNB configuration chapter
MME file: /usr/local/etc/oai/mme.conf to update
GUMMEI_LIST = ( MCC=”208″ ; MNC=”92″; MME_GID=”4″ ; MME_CODE=”1″; } );
TAI_LIST = ({MCC=”208″ ; MNC=”92″; TAC = “1”; } );
A HSS database in text is in: opencells-mods/opencells_db.sql
for phpmyadmin
# sudo ln -s /usr/share/phpmyadmin /var/www/html
10 users is network 208/92 (a French test network) are also created
# nano /usr/local/etc/oai/hss.conf
HSS Configure the password for MySQL set password as the password you created during MySQL installation
uncomment #OPERATOR_key = “11111111111111111111111111111111”; # OP key matching your database

# cd ~/openair-cn/scripts
# ./hss_db_import 127.0.0.1 root linux oai_db ~/opencells-mods/opencells_db.sql

supposed your password is linux
program the Usim
apt-get install python-pyscard python-serial python-pip
pip install pytlv

to find ki matching you should k at startup of
# ./run_hss
to find opc
# ./auchss.py -o 11111111111111111111111111111111 -k 6874736969202073796D4B2079650A73
# sudo python pySim-prog.py --type="sysmoUSIM-SJS1" --mcc=208 --mnc=92 --imsi=208920100001108 --opc=777f0406a78d9598b0330d63f4c52199 --ki=6874736969202073796D4B2079650A73 --iccid=8988211000000227713 --pin-adm=40303607 --acc=0200

Change pin-adm=40303607 –acc=0200 with your own values
Running !!

# cd ~/openair-cn/scripts
# sudo ./run_hss
# sudo ./run_mme
# sudo ./run_spgw
# cd ~/openairinterface5g
# sudo -E targets/bin/lte-softmodem.Rel14 -O targets/PROJECTS/GENERIC-LTE-EPC/CONF/enb.band7.tm1.25PRB.lmssdr.conf --rf-config-file ~/trx-lms7002m/config-limeSDR/LimeSDR_Mini_v06.ini -d

The last puzzle piece with the lousy bursty throughput and those log errors:
[PHY][W][eNB 0, CC 0] frame 733, subframe 4, UE 0: ULSCH consecutive error count reached 20, triggering UL Failure
[MAC][I][UL_failure_indication] [eNB 0][UE 0/80e6] Frame 733 subframeP 4 Signaling UL Failure for UE 0 on CC_id 0 (timer 0)
[PHY][E]ERROR: Format 1A: rb_alloc (1ff) > RIV_max (144)
was partly solved by using the lte-softmodem -d switch Enable soft scope and L1 and L2 stats (Xforms), since it was built with the -x –xforms option, and partly by randomly moving the phone around and noticing there was a sweet spot where Firefox would download and install very fast.
Good luck
