--- title: Roaming --- ## 0. Introduction Now, we will explain how to install and test 5G Core Roaming using Open5GS. Since we cannot test roaming with UERANSIM, we will use the test environment of Open5GS. We can only use the LBO method. HR roaming will be implemented at a later date. And also, 5G roaming has been implemented according to the document below. ``` TS29.500 6 General Functionalities in Service Based Architecture 6.1 Routing Mechanisms 6.1.4.3 Routing across PLMN ``` Let's start the explanation assuming that the connection test of the UE to this single host has been completed. ## 1. Your First Roaming with Test Program #### Build & Install We'll start with the `roaming-tier3` branch from now on. ``` $ git clone https://github.com/open5gs/open5gs $ cd open5gs $ git checkout roaming-tier3 $ meson build --prefix=`pwd`/install $ ninja -C build install ``` #### Configure FQDN to DNS For routing to Home PLMN, NRF, AUSF and UDM address in H-PLMN shall use FQDN format, so please edit the /etc/hosts file as follows. ```diff $ diff -u hosts.old hosts.new --- hosts.old 2023-10-02 11:58:54.261154726 +0900 +++ hosts.new 2023-10-02 11:59:02.868771248 +0900 @@ -1,6 +1,18 @@ 127.0.0.1 localhost 127.0.1.1 open5gs +127.0.1.10 nrf.5gc.mnc070.mcc999.3gppnetwork.org +127.0.1.11 ausf.5gc.mnc070.mcc999.3gppnetwork.org +127.0.1.12 udm.5gc.mnc070.mcc999.3gppnetwork.org + +127.0.2.10 nrf.5gc.mnc001.mcc001.3gppnetwork.org +127.0.2.11 ausf.5gc.mnc001.mcc001.3gppnetwork.org +127.0.2.12 udm.5gc.mnc001.mcc001.3gppnetwork.org + +127.0.3.10 nrf.5gc.mnc010.mcc315.3gppnetwork.org +127.0.3.11 ausf.5gc.mnc010.mcc315.3gppnetwork.org +127.0.3.12 udm.5gc.mnc010.mcc315.3gppnetwork.org + # The following lines are desirable for IPv6 capable hosts ::1 ip6-localhost ip6-loopback fe00::0 ip6-localnet ``` #### Running V-PLMN 5G Core and H-PLMN 5G Core in the Single Host 5G Core requires root privileges as it uses reserved ports such as http(80) or https(443). ``` $ sudo ./build/tests/app/5gc -c ./build/configs/examples/5gc-sepp1-999-70.yaml $ sudo ./build/tests/app/5gc -c ./build/configs/examples/5gc-sepp2-001-01.yaml $ sudo ./build/tests/app/5gc -c ./build/configs/examples/5gc-sepp3-315-010.yaml ``` Performs a test of UE access while roaming subscribed to H-PLMN. ``` $ ./build/tests/registration/registration -c ./build/configs/examples/gnb-999-70-ue-001-01.yaml simple-test $ ./build/tests/registration/registration -c ./build/configs/examples/gnb-999-70-ue-315-010.yaml simple-test $ ./build/tests/registration/registration -c ./build/configs/examples/gnb-001-01-ue-999-70.yaml simple-test $ ./build/tests/registration/registration -c ./build/configs/examples/gnb-001-01-ue-315-010.yaml simple-test $ ./build/tests/registration/registration -c ./build/configs/examples/gnb-315-010-ue-999-70.yaml simple-test $ ./build/tests/registration/registration -c ./build/configs/examples/gnb-315-010-ue-001-01.yaml simple-test ``` You can see the sample traffic. -- [[5g-roaming-lbo.pcapng]]({{ site.url }}{{ site.baseurl }}/assets/pcapng/5g_roaming_lbo.pcapng). ## 2.
