Before continuing with the instructions, please check the Installation page to clarify that you have installed everything.
sudo python ~/mininet/custom/datacenterTest.py
If everything is fine, it will appear on this terminal a list of switches (s0-s1), hosts (h0-h63) and a Nat.
Run the EPC within Mininet
In the terminal of Mininet:
mininet> xterm h0 h0 h0
Now, there are three Minitet terminal of the host0. We totally recommend to launch the EPC in the host0 because the EPC configuration is linked to this host.
In one mininet terminal run the hss:
In another mininet terminal run the mme:
Important to check that this appears on the hss terminal: 'STATE_CLOSED' -> 'STATE_OPEN' 'imdeaEPC.my.realm'
Finally, run the spgw:
Pre srsLTE eNodeB configuration
Go to the srsLTE folder
sudo gedit build/srsenb/src/enb.conf
And change these lines to those ones:
tac = 0x0001 mcc = 208 mnc = 95 mme_addr = 10.0.0.1 #mininet host0 IP gtp_bind_addr = X.X.X.X
X.X.X.X is the IP of the physical host (enb) interface connected to Mininet
Change the route to connect to Mininet and to the EPC gateway:
sudo ip route add 10.0.0.0/12 via Y.Y.Y.Y sudo ip route add 10.16.0.0/12 via Y.Y.Y.Y
Y.Y.Y.Y is the IP of the virtual machine (the Mininet/EPC virtual machine)
Execute the eNodeB code
sudo build/srsenb/src/./srsenb enb.conf
If it is well connected, it will appear one enb connected/attached on the MME terminal.
Go to the srsLTE folder
Pre srsLTE configuration
sudo gedit build/srsue/src/ue.conf
Change these lines to those ones:
algo = milenage op = 840337C3D45397CE8EA8609FFDC47224 #amf = 8000 k = 352857A8F4EB1C1EF485F4356CC925D0 imsi = 901700000012948
Execute the UE code
sudo build/srsue/src/./srsue ue.conf
It the UE is well connected to the eNodeB and to the EPC, you will see on the eNodeB terminal:
In addition, in the MME terminal you should see on the statistics one connected and attached UE .
Finally, the the EPC gives an IP to the UE. This IP appears on the UE terminal. Note that this IP has to be within the range of 10.16.0.0/12:
Add the route to connect the UE to the gateway
sudo route add default gw 10.16.0.1
At this moment, the UE can do ping to the EPC. If you want to connect to internet, it is needed to change the DNS server
sudo gedit /etc/resolv.conf
Add this line at the end:
At this moment, the UE has total connectivity to internet. Have fun!![hss_crop]
