eNB s1 Emulator

Data throughput performance wont work and iperf udp 1400 mtu only work

Installation

On a Ubuntu systems you can install with:

apt-get install -y python3-pip libsctp-dev swig python3-pyscard git net-tools bridge-utils resolvconf
sysctl -w net.ipv4.ip_forward=1
echo "nameserver 8.8.8.8">/etc/resolvconf/resolv.conf.d/head
service resolvconf restart
echo "alias toollog='journalctl -fu tool'">>/root/.bashrc
source /root/.bashrc

Now we can clone the repository with:

Finally we will need to install all of the Python packages needed to run the tool.

We can install all these packages using pip3 with:

sudo pip3 install -r requirements.txt

Usage

Many variables needed for SA1P and NAS are defined inside the session_dict_initialization function. You can change them to meet your own needs.

When you call the script these are the options available:

#IPV6 IP Command
./simulator.py -P start-simulator --enbip 2001:db8:0:f101::1 --mmeip 2001:db8:0:f101::2    
#IPv4 IP Command
./simulator.py -P start-simulator --enbip 192.168.197.180 --mmeip 192.168.197.201
./simulator.py -P s1-setup --mcc 333 --mnc 333 --enbid 100000 --tac1 63 
 (optional parameters for s1-setup "--enbname value")
 
./simulator.py -P s1-reset
./simulator.py -P attach --imsi 333010000000001 --key e8767ccf27d3fae385b16bf073c912a2 --opc 982559004308ee438a99b5baf6a59c45
 (optional parameters for attach  "--attachtype imsi or guti ")
 
./simulator.py -P idle --imsi 333010000000001
./simulator.py -P tau --imsi 333010000000001
./simulator.py -P tau-p --imsi 333010000000001
./simulator.py -P tau-combine --imsi 333010000000001
./simulator.py -P service-request --imsi 333010000000001
./simulator.py -P x2 --imsi 333010000000001
./simulator.py -P active-users
./simulator.py -P detach --imsi 333010000000001
./simulator.py -P stop-simulator

Run Data using netns Example for data

ip netns exec 333010000000001 ping 8.8.8.8

log path :- journalctl -fu tool
