1. free5gcとは

公式サイト
https://www.free5gc.org/

オープンソースの5GC(5G Core)です。台湾の国立交通大学が開発主導しているプロジェクトの様でかなり5GCとして色んな機能がサポートされており、お気軽に5Gの基地局・端末シュミレーター(UERANSIM)等と組み合わせて5GC通信を試す事ができます。と言われても5GCの前提知識がないと何がなんだか分からないと思いますが、そちらは別途以下の記事等を参考にしてください。

超簡単に言うと、今現在(2021/9/1現在)日本の携帯電話事業者が提供している5Gサービスは正確には5G NSA(non-standalone)というシステムで、コアネットワーク側は5G EPCと呼ばれる4Gのコア(EPC)を5Gで使えるようにした物を使っています。5GCは5G専用のコアで5G RAN+5GCの組み合わせで真の5Gシステムといえる5G SA(standalone)が構成されます。最近ではLocal5Gというキャリアのネットワークを使わない工場内とか空港内とか閉鎖的環境で5G技術を使用して、DX推進しようという活発な動きもあります。Local5Gでも5G SAの場合はコアは5GCが使われます。

という訳で早速Installして使ってみましょう！

使用するVersionは以下の通りです。

free5GC version: v3.0.5
UERANSIM version 3.2.3

2. Install環境

Windows PC上にVirualBoxを入れて、VirualBox上でLinux(Ubuntsu)を動かし、Linux上で5GCを構築します。

VirtualBoxの入手先はこちら
最新Versionは6.1.26の様ですが、今回は6.1.22を使ってます。最新のVirtualBoxでも動作すると思います。

インストールするUbuntsuのイメージ(ubuntu-20.04.3-live-server-amd64.iso)はこちら

注意:最新のUbuntsu入れるとKernel versionが新し過ぎてgtpモジュールのコンパイルが出来ません。なので20.4を使います。

使用システム（ホストPC）

OS 名:Microsoft Windows 10 Home
バージョン:10.0.19042 ビルド 19042
プロセッサ:AMD Ryzen 5 1600 (Six-Core Processor、3200 Mhz)
インストール済みの物理メモリ (RAM):32.0 GB
SSD:464GB

VirtualBox側（ゲスト)
メモリ1G
ディスク:10G
OS:ubuntu-20.04.3-live-server-amd64

3. Linux Install

適当にデフォルトのままでも動くのですが、後々のため（別VMにInstallするUERANSIMと通信させるため）にNICを追加しておきます。VirtualBoxの設定メニュー->ネットワーク->アダプター2のところでネットワークアダプターを有効化しておきます。

あとはダウンロードしたisoイメージを指定してあげてVMを起動して普通にLinuxをInstallします。Host PCからLinuxにつなげるためにInstall時にOpenSSHをONにしておきましょう。以下はhostnameをfree5gcにした場合の例です。ServerイメージなのでGUIなしです。

InstallしたらKernel versionを確認しておきましょう。5.8以上だとgtpモジュールのコンパイルが失敗します。free5gcの公式では5.0.0-23-genericにしろ書いてありますが、5.4.0-81-genericでも動作します。

q14537@free5gc:~$ uname -r
5.4.0-81-generic

また今回は2つ目のNICに静的にIPアドレスを付与しています。Defautl Gatewayにアドレスをいれると設定を書き換えないとインターネットに出られないかもしれません。enp0s8のgateway4に設定がある場合は以下の様にコメントアウトしてしまいましょう。

q14537@free5gc:~$ cat /etc/netplan/00-installer-config.yaml
# This is the network config written by 'subiquity'
network:
  ethernets:
    enp0s3:
      dhcp4: true
    enp0s8:
      addresses:
      - 192.168.56.103/24
        #      gateway4: 192.168.56.1
      nameservers:
        addresses: []
        search: []
  version: 2

4. free5gc Install

LinuxのInstallが終われば以下の公式インストラクションに従い、もろもろInstallします。Installの細かい事はインストラクション通りにコマンド打っていくだけなので割愛。

という訳であっという間に5GCの完成です。いやー早い。

free5GCがサポートしているの以下のNF(NetworkFunction(5GCの構成要素))です。

q14537@free5gc:~/free5gc/NFs$ ls -l
total 40
drwxrwxr-x 18 q14537 q14537 4096 Sep  1 14:58 amf

冒頭のリンク先にも絵がありますが、5GCの簡単なネットワークは以下の様になっており用途別に様々なNFが定義されているのですが、free5gcでサポートしているの以下の青の四角で囲ったNFです。赤の部分は後程InstallするUERANSIMで疑似をしますが、free5gcにもテストコールのモジュールがついているのでそちらでも疑似できます。

詳しいNFの説明は以下も参考になります。

それではテストコールをしてみましょう！

5. コールテスト

インストールが終わったらtest.shというシェルスクリプトが用意されていますのでコールテストを行ってみましょう。以下の様に様々なコールフローのシナリオが用意されています。

q14537@free5gc:~/free5gc$ ./test.sh
Usage: ./test.sh [ TestRegistration | TestGUTIRegistration | TestServiceRequest | TestXnHandover | TestN2Handover | TestDeregistration | TestPDUSessionReleaseRequest | TestPaging | TestNon3GPP | TestReSynchronisation | TestDuplicateRegistration ]

まずは通常のRegistration。いわゆるUE(端末)が電源ONしてネットワークに登録され通信を行う事です。このTestRegistrationのシナリオでは5GCの立ち上げ->UE電源ON->認証->通信可能な状態に遷移->端末からインターネットにパケット送信->UE電源OFF->5GCシャットダウンまで自動に行われる様です。

q14537@free5gc:~/free5gc$ ./test.sh TestRegistration
[sudo] password for q14537:

以下実行結果。なんだかメッセージがいっぱいでて何がなんだかわからないと思いますが、やっている事は5GCのNF達を起動し、5GCネットワークを構築し、5GCに疑似基地局経由の疑似UEから認証し、パケットを送っているのです。


q14537@free5gc:~/free5gc$ ./test.sh
[sudo] password for q14537:
Usage: ./test.sh [ TestRegistration | TestGUTIRegistration | TestServiceRequest | TestXnHandover | TestN2Handover | TestDeregistration | TestPDUSessionReleaseRequest | TestPaging | TestNon3GPP | TestReSynchronisation | TestDuplicateRegistration ]
