+# 5G NSA in L2-Sim Setup
+
+## Table of Contents
+
+[[_TOC_]]
+
+## 1 Overview
+
+This document tells about the reference guide for the setup of the environment for NSA 5G configuration using the openair interface code base. This shall be the reference setup before we start the testing on the SequansRD . Since the NSA was not tested by OAI in the CI, there are few things to be taken into account to bring up the setup. This document is being created to identify the issues and resolve them and provide the steps to easily re-create the NSA setup. Once this is achieved the next step is to have the SequansRD based NSA setup.
+
+The NSA mode functional is shown in the following image:
+![](images/Multi-UE-Proxy.png)
+
+## 2 Message flow for NSA setup
+Following slides show the message flow between the LTE-UE and NR-UE of OAI and the communication between eNB/gNB for NSA setup.
+Also the important logs to be verified for the NSA setup are documented in the document

+_Note: Above configuration is with reference to workiong configuraton on Firecell's setup. On different machine, this configuration shall be udpated w.r.t new setup's environment. _
+
+### 3.2 Build Proxy
+```bash
+cd .../oai-lte-multi-ue-proxy
+make
+```
+### 3.3 Deploy EPC
+For running the System Simulator this step is not mandatory since it is not used when running with the TTCN environment.
+The first step is to install some mandatory packages from Ubuntu distribution:
+- apt-transport-https
+- ca-certificates
+- curl
+- gnupg
+- lsb-release
+
+This can be easily done by using apt-get command:
+
+```bash
+$sudo apt-get install apt-transport-https ca-certificates curl gnupg lsb-release
+```
+Now it is possible to download the docker package and install it
+```bash
+$sudo curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg
+```
+Update apt-get list of packages
+```bash
+$echo \ "deb [arch=amd64 signed-by=/usr/share/keyrings/docker-archive-keyring.gpg]
+https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker list > /dev/null
+$sudo apt-get update
+```
+Install docker
+```bash
+$sudo apt-get install docker-ce docker-ce-cli containerd.io
+```
+Once the package is installed the user should have the proper permissions to run docker
+```bash
+$sudo usermod -a -G docker "yourusername"
+```
+where "yourusername" shall be replaced with the user login information of the user running the docker instances.
+
+**Now you have to reboot the machine in order to have the changes applied to the system.**
+
+Run the command "groups" after rebooting in order to confirm docker was added to the list.
+
+```bash
+$groups
+$dpkg --list | grep docker
+ii  docker-ce  5:20.10.7~3-0~ubuntu-bionic amd64 Docker: the open-source application container engine
+ii  docker-ce-cli 5:20.10.7~3-0~ubuntu-bionic amd64 Docker CLI: the open-source application container engine
+ii  docker-ce-rootless-extras 5:20.10.7~3-0~ubuntu-bionic amd64 Rootless support for Docker.
+ii  docker-scan-plugin 0.8.0~ubuntu-bionic amd64 Docker scan cli plugin.
+```
+Now we should download and install docker compose for managing multiple docker instances:
+
+```bash
+$sudo curl -L "https://github.com/docker/compose/releases/download/1.29.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
+$sudo chmod +x /usr/local/bin/docker-compose
+```
+If not already registered, you need to create the user account in and make the login to pull the ubuntu:bionic and cassandra:2.1 images from docker store:
+```bash
+$docker login
+Login with your Docker ID to push and pull images from Docker Hub. If you don't
+have a Docker ID, head over to https://hub.docker.com to create one.
+Username: oai01
+Password:
+WARNING! Your password will be stored unencrypted in
+/home/hscuser/.docker/config.json.
+Configure a credential helper to remove this warning. See
+https://docs.docker.com/engine/reference/commandline/login/#credentials-store
+
+Login Succeeded
+
+$ docker pull ubuntu:bionic
+$ docker pull cassandra:2.1
+```
+**NOTE: By default, traffic from containers connected to the default bridge network is NOT forwarded to the outside world. To enable the forwarding, it is necessary to change the following setting:**
+
+- Configure the linux kernel to allow IP forwarding
+```bash
+$sudo sysctl net.ipv4.conf.all.forwarding=1
+```
+- Change the policy for the iptables FORWARD policy from DROP to ACCEPT
+```bash
+$ sudo iptables -P FORWARD ACCEPT
+```
+Pulling container images:
+```bash
+$ docker pull oaisoftwarealliance/oai-spgwc:latest
+$ docker pull  oaisoftwarealliance/magma-mme:latest
+$ docker pull oaisoftwarealliance/oai-hss:latest
+$ docker pull oaisoftwarealliance/oai-spgwu-tiny:latest
+```
+Re-tag the container images:
+```bash
+$ docker image tag oaisoftwarealliance/oai-hss:latest oai-hss:production
+$ docker image tag oaisoftwarealliance/oai-spgwu-tiny:latest oai-spgwu-tiny:production
+$ docker image tag oaisoftwarealliance/oai-spgwc:latest oai-spgwc:production
+$ docker image tag oaisoftwarealliance/magma-mme:latest magma-mme:master
+$ docker logout
+```
+
+Clone the EPC repository for getting the docker-compose file
+
+```
+$ git clone https://github.com/OPENAIRINTERFACE/openair-epc-fed.git
+
+```
+set the PATHTOEPC to the cloned directory. Now need to update the submodules to get the access to oai_db.cql file to initilize the database container
+```
+$ cd <PATHTOEPC>
+git submodule init
+git submodule update --recursive
+```
+Bring up the database continer by following the commands
+```
+$ cd docker-compose/magma-mme-demo
+$ docker-compose up -d db_init
+Creating network "demo-oai-private-net" with the default driver
+Creating network "demo-oai-public-net" with the default driver
+Creating demo-cassandra ... done

+OK
+```
+You must have the "OK" message in the demo-db-init container logs, in order to proceed with the next steps. If OK is not displayed, please repeat the command.
+**NOTE: the error messages are normal. They do not prevent the system from working properly.**
+Remove prod-db-init container:
+```bash
+$ docker rm -f demo-db-init
+```
+On your EPC docker host, check the routing table and identify the default gateway:
+```bash
+$ route -n 
+Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 0.0.0.0 192.168.253.1 0.0.0.0 UG 100 0 0 enp1s0 ...
+```
+Use the default gateway as DNS in the magma-mme-demo and Edit/modify the docker-compose file in order to:
+```bash
+$ cd <PATHTOEPC>/sequansRD/EPC/docker-compose/magma-mme-demo
+$ vi docker-compose.yml
+```
+- DEFAULT_DNS_IPV4_ADDRESS: 192.168.253.1
+- In services, go to magma_mme and change the name of image to "magma-mme:master" and container_name to "demo-magma-mme" e.g.
+```bash
+            magma_mme:
+        	image: magma-mme:master
+        	container_name: demo-magma-mme
+
+```
+**NOTE: Please make sure you add the proper route in the eNB server as shown earlier**
+Now we can start EPC:
+```bash
+$ cd docker-compose/magma-mme-demo
+$ docker-compose up -d db_init
+$ docker logs demo-db-init --follow
+
+$ docker-compose up -d oai_spgwu

+In order to access the EPC components from the eNB we need to know the IP address of MME and SP-GW. In order to retrieve those IPs you can run the following commands:
+For MME:
+```bash
+$ docker inspect --format="{{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}" demo-magma-mme 192.168.61.4
+```
+For SP-GW:
+```bash
+$ docker inspect --format="{{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}" demo-oai-spgwu-tiny 192.168.61.6
+```
+
+**NOTE: MME has a short life. It is better to compose it every time before using it. Each time you modify the docker-compose file, you have to repeat docker-compose up -d oai_spgwu. Each time you reboot your machine or you see with "docker ps -a" that an EPC component has exited you have to restart from scratch following these steps:**
+
+```bash
+$ cd <PATHTOEPC>/docker-compose/magma-mme-demo
+$ docker-compose down
+$ docker ps -a
+```
+make sure that linux kernel allows IP forwarding:
+
+```bash
+$ sudo sysctl net.ipv4.conf.all.forwarding=1
+$ sudo iptables -P FORWARD ACCEPT
+$ sudo iptables \--list
+```
+Restart Database
+```bash
+$ docker-compose up -d db_init
+$ docker logs demo-db-init  --follow
+$ docker rm -f demo-db-init
+```
+please make sure the last line is OK otherwise you need to repeat the previous steps
+Restart **EPC**
+```bash
+$ docker-compose up -d oai_spgwu
+$ docker ps -a
+```
+For restart from scratch, run the below shell script also :
+```bash
+$ cd <PATHTOEPC>/sequansRD/EPC/docker-compose/magma-mme-demo
+$ ./startEPC.sh
+```
+In order to check errors in MME and HSS you can do the follow:
+```bash
+$ docker logs demo-oai-hss 2>&1 > hss.log
+$ docker logs demo-magma-mme 2>&1 > mme.log
+```
+### 3.4 Build OAI
+```bash
+cd .../openairinterface5g
+source oaienv
+cd cmake_targets
+sudo ./build_oai --UE --eNB --nrUE --gNB
+
+
+```
+
+### 3.5 Generate NV files
+```bash
+cd openairinterface5g/cmake_targets
+1. ./nas_sim_tools/build/conf2uedata -c ../ci-scripts/conf_files/episci/episci_ue_test_sfr.conf -o .
+2. ./nas_sim_tools/build/usim -g -c ../ci-scripts/conf_files/episci/episci_ue_test_sfr.conf -o .
+3. ./nas_sim_tools/build/nvram -g -c ../ci-scripts/conf_files/episci/episci_ue_test_sfr.conf -o .
+
+```
+
+### 3.6 Run NSA mode with the script
+```bash
+./proxy_testscript.py --num-ues 1 --mode=nsa --duration=300
+```
+Duration is optional.
+Note: This step is for checking the sanity of the setup and is optional. 
+### 3.7 Run without the proxy_testscript.py
+The launch order is important, as follows.
+#### 3.7.1 Launch eNB in Terminal 1
+```bash
+cd .../openairinterface5g
+source oaienv
+cd cmake_targets
+node_id=1
+sudo -E LD_LIBRARY_PATH=/home/firecell/openairinterface5G/openairinterface5g/cmake_targets/ran_build/build: taskset --cpu-list 1 ./ran_build/build/lte-softmodem -O ../ci-scripts/conf_files/episci/proxy_rcc.band7.tm1.nfapi.conf --noS1 --emulate-l1 --log_config.global_log_options level,nocolor,time,thread_id --nsa | tee eNB.log 2>&1
+```
+#### 3.7.2 Launch Proxy in Terminal 2
+```bash
+cd .../oai-lte-multi-ue-proxy
+sudo -E ./build/proxy 1 --nsa enb_ipaddr gnb_ipaddr proxy_ipaddr ue_ipaddr
+or
+sudo ./build/proxy 1 --nsa
+```
+If you do not specify the parameters ending with ipaddr, the default IP addresses are as follows:
+- enb_ipaddr = 127.0.0.1
+- gnb_ipaddr = 127.0.0.2
+- proxy_ipaddr = 127.0.0.1
+- ue_ipaddr = 127.0.0.1
+#### 3.7.3 Launch lteUE in Terminal 3
+```bash
+cd .../openairinterface5g
+source oaienv
+cd cmake_targets
+node_id=2
+sudo -E LD_LIBRARY_PATH=/home/firecell/openairinterface5G/openairinterface5g/cmake_targets/ran_build/build: taskset --cpu-list 2 ./ran_build/build/lte-uesoftmodem -O ../ci-scripts/conf_files/episci/proxy_ue.nfapi.conf --L2-emul 5 --nokrnmod 1 --noS1 --num-ues 1 --node-number 2 --log_config.global_log_options level,nocolor,time,thread_id --nsa | tee ue.log 2>&1
+```
+Note: If error "[MAC] E No $OPENAIR_DIR" is received on execution of lte-uesoftmodem, use below command for execution.
+```
+sudo -E OPENAIR_DIR=../ LD_LIBRARY_PATH=/home/firecell/openairinterface5G/openairinterface5g/cmake_targets/ran_build/build: taskset --cpu-list 2 ./ran_build/build/lte-uesoftmodem -O ../ci-scripts/conf_files/episci/proxy_ue.nfapi.conf --L2-emul 5 --nokrnmod 1 --noS1 --num-ues 1 --node-number 2 --log_config.global_log_options level,nocolor,time,thread_id --nsa | tee ue.log 2>&1
+```
+#### 3.7.4 Launch gNB in Terminal 4
+```bash
+cd .../openairinterface5g
+source oaienv
+cd cmake_targets
+node_id=3
+sudo -E LD_LIBRARY_PATH=/home/firecell/openairinterface5G/openairinterface5g/cmake_targets/ran_build/build: taskset --cpu-list 1 ./ran_build/build/nr-softmodem -O ../ci-scripts/conf_files/episci/proxy_rcc.band78.tm1.106PRB.nfapi.conf --nfapi VNF --noS1 --emulate-l1 --log_config.global_log_options level,nocolor,time,thread_id --nsa | tee gNB.log 2>&1
+```
+#### 3.7.5 Launch nrUE in Terminal 5
+```bash
+cd .../openairinterface5g
+source oaienv
+cd cmake_targets
+node_id=2
+sudo -E LD_LIBRARY_PATH=/home/firecell/openairinterface5G/openairinterface5g/cmake_targets/ran_build/build: taskset --cpu-list 2 ./ran_build/build/nr-uesoftmodem -O ../ci-scripts/conf_files/episci/proxy_nr-ue.nfapi.conf --nokrnmod 1 --nfapi STANDALONE_PNF --node-number 2 --emulate-l1 --log_config.global_log_options level,nocolor,time,thread_id --nsa | tee nrUE.log 2>&1
+```
+
+### 3.8 Checking the log result
+After running the programs for 30 seconds or more, stop the processes using Ctrl-C. Open the log files and check the following logs to verify the run results.
+- gNB.log : search for "CFRA procedure succeeded" log message for each UE.
+- eNB.log : search for "Sent rrcReconfigurationComplete to gNB".
+- nrUE.log : search for "Found RAR with the intended RAPID".
+- ue.log : search for "Sent RRC_CONFIG_COMPLETE_REQ to the NR UE".
