## 1. Description
This tutorial shows how to use OAI 5g Core network in standalone deployment with commercial gNB and COTS UE. The tutorial and testbed was made by [Opensource5g group](http://www.opensource5g.org) located in BUPT, Beijing.
- The core network is deployed in two Virtual Machines
- The commercial gNB used for this tutorial is Amarisoft
- The COTS UE used for this tutorial is Xiaomi K30i
- [Openair-spgwu-tiny](https://github.com/OPENAIRINTERFACE/openair-spgwu-tiny/tree/gtp_extension_header) is choosen as the UPF for this tutorial
## 2. Pre-requisites
The host machine hosting the virtual machines have the below configuration:
| Params | Value |
| :----- | ----------------------: |
| CPU | Intel Core i9-9980HK 16 |
| Memory | 32 GB |
| Disk | 512 GB SSD |
| System | Ubuntu 18.04 |
The virtual machines are configured using KVM, though any other virtual machine manager can be used. To install KVM and virt-manager follow the below commands:
```bash=
~$ sudo apt-get install qemu-kvm
~$ sudo apt-get install qemu
~$ sudo apt-get install virt-manager
~$ sudo apt-get install virt-viewer
~$ sudo apt-get install libvirt-bin
~$ sudo apt-get install bridge-utils
```
Verify the installation:
```bash=shell
~$ sudo kvm-ok
```
If everything is ok, you would see
```bash=shell
INFO: /dev/kvm exists
KVM acceleration can be used
```
Create virtual machines by using virt-manager GUI:
```bash=shell
~$ sudo virt-manager
```
## 3. Creating Virtual Machines
Recommendation is to create two VMs with 4 Cores, 8GB memory, 40GB disk. First one for 5G Core control plane 5G-CCP, and the second for 5G User plane 5G-UP.
Network configuration for both the VMs
- 5G-CCP VM
| NIC | Network Source | IP address | Usage |
| ---- | ----------------: | :-------------- | ----: |
| ens3 | NAT | 192.168.122.197 | SBI |
| ens9 | Bridge to Phy NIC | 192.168.199.28 | NGAP |
- 5G-UP VM
| NIC | Network Source | IP address | Usage |
| ----- | :---------------- | --------------: | -----: |
| ens9 | NAT | 192.168.122.78 | N4 |
| ens10 | NAT | 192.168.122.55 | N6/SGi |
| ens12 | Bridge to Phy NIC | 192.168.199.126 | N3 |
## 4. Building Network functions
The branch commits used at the time of the demo are listed below:
| NF Name | Branch Name | Commit |
| ------- | -------------------: | :--------------------------------------- |
| AMF | bupt_amf | 951db2252b149d78f55aa143a4639d1c25c3dac0 |
| SMF | develop | fcc61f82cc5e0054eeb8c37860cb825e85259036 |
| SPGW-u | gtp_extension_header | f13f4a5e2807355d23f136119f85fbf48ed569ea |
### 4.1 Build AMF
- Login to 5G-CCP VM and open the terminal to fetch, build and install the AMF.
- The build can be made in two modes Debug and Release. Debug mode will provide more logs for debuging but may effect the performance.
``` bash=
~$ git clone -b bupt_amf https://gitlab.eurecom.fr/oai/cn5g/oai-cn5g-amf.git
~$ cd ./oai-cn5g-amf/
~$ cd ./build/scripts/
~$ sudo ./build_amf --install-deps --force
~$ sudo ./build_amf --clean --Verbose --build-type Debug --jobs
```
### 4.2 Build SMF
- Remain logged in to the same virtual machine to compile and install SMF
- The build can be made in two modes Debug and Release. Debug mode will provide more logs for debuging but may effect the performance.
``` bash=
~$ git clone -b develop https://gitlab.eurecom.fr/oai/cn5g/oai-cn5g-smf.git
~$ cd ./oai-cn5g-smf/
~$ cd ./build/scripts/
~$ sudo ./build_smf --install-deps --force
~$ sudo ./build_smf--clean --Verbose --build-type Debug --jobs
```
### 4.3 Build SPGWU
- Login to 5G-UP VM and open a terminal to fetch, build and install SPGWU
- The build can be made in two modes Debug and Release. Debug mode will provide more logs for debuging but may effect the performance.
``` bash=
~$ git clone -b gtp_extension_header https://github.com/OPENAIRINTERFACE/openair-spgwu-tiny.git
~$ cd ./openair-spgwu-tiny/
~$ sudo apt-get update && DEBIAN_FRONTEND=noninteractive apt-get upgrade --yes && DEBIAN_FRONTEND=noninteractive apt-get install --yes \
psmisc \
net-tools \
iproute2 \
ethtool \
iptables \
tshark \
libgoogle-glog0v5 \
libdouble-conversion1 \
libconfig++9v5 \
libboost-system1.65.1 \
&& rm -rf /var/lib/apt/lists/*
~$ cd ./build/scripts/
~$ sudo ./build_spgwu --install-deps --force
~$ sudo ./build_spgwu --clean --build-type Debug --jobs --Verbose
```

### 6.4 Start the gNB and turn on the UE
- Start the gNB and turn on the mobile phone or change from airplane mode to signalling mode.
- Once the UE is successfully connected and receives an ip-address try to reach public site via internet and then stop all the core network components and gNB to analyze the pcaps, logs, etc.
## 7. Analyzing the Results
- Log files and pcaps for the demo

### 7.1 Analyzing initial message exchange
Using wireshark open core.pcap use the filter `ngap || http || pfcp || gtp`
1. Initial UE Message registration request: Packet 197
2. Authentication and security process: Packet 394, 401, 556, 564
3. Registration complete: 768
4. PDU session establishment request: Packet 883
5. AMF <--> SMF PDU session request: Packet 984
6. SMF <--> UPF PFCP session establishment: Packet 1164 & 1176
7. Allocated UE IP-address can be seen in Packet 1164, 1274, 1359
8. Echo request response between UE and Dn:Packet 2076, 2080
