srsRAN research #403

Closed pirog-spb closed 11 months ago

pirog-spb commented 1 year ago

srsRAN project provides 4G/5G RAN software based solutions which could be used as complete RAN solution or together with virtual radio(ZeroMQ). I'm as a eUPF bundle vendor integrates with yet another virtual RAN solution in order to overcome current virtual RAN(UERANSIM) constrains and to verify eUPF interoperability with RAN.

Acceptance criteria:

Explore srsRAN project description

Usable scenario is ZeroMQ-based Setup

srsRAN Project is a 5G CU/DU solution and does not include a UE application. However, srsRAN 4G does include a prototype 5G UE (srsUE) which can be used for testing.

some approach: @gradiant helm charts described in Open5GS EPC and SRS LTE in kubernetes

There is an image openverso/srsran-5g:23_5

For UE there is an image openverso/srsran-4g:23_04_1

📝Note from openaicellular

Natively, ZeroMQ with srsRAN supports only one eNB/gNB and one UE configuration but it can be extended to support multiple UEs using GNU Radio. Have a look at the tutorial to do this here.

Create simple deployment with eUPF, Open5GS and srsRAN(ZeroMQ)

gNB config from scenario ZeroMQ-based Setup is not fully compatible in syntax with the latest release 23.5.

Working gNb config is:

```yaml # This configuration file example shows how to configure the srsRAN Project gNB to allow srsUE to connect to it. # This specific example uses ZMQ in place of a USRP for the RF-frontend, and creates an FDD cell with 10 MHz bandwidth. # To run the srsRAN Project gNB with this config, use the following command: # sudo ./gnb -c gnb_zmq.yaml amf: addr: 10.233.22.229 bind_addr: 10.233.64.35 rf_driver: device_driver: zmq # The RF driver name. device_args: tx_port=tcp://127.0.0.1:2000,rx_port=tcp://127.0.0.1:2001,base_srate=11.52e6 # Optionally pass arguments to the selected RF driver. srate: 11.52 # RF sample rate might need to be adjusted according to selected bandwidth. tx_gain: 75 # Transmit gain of the RF might need to adjusted to the given situation. rx_gain: 75 # Receive gain of the RF might need to adjusted to the given situation. cell_cfg: dl_arfcn: 368500 # ARFCN of the downlink carrier (center frequency). band: 3 # The NR band. channel_bandwidth_MHz: 10 # Bandwith in MHz.

Configuring UE

if you wanted to use the srsue tool with 5G NR instead of LTE, you might use the following command: srsue --ue.radio multi --ue.phy nr

Configuring gNB

Example configuration files can be found in the configs/ folder in the srsRAN Project codebase. Looking at configs/gnb_rf_b210_fdd_srsUE.yml: This particular configuration is intended to be used with srsUE. Note the pdcch parameters set in the cell_cfg section. These are set to match the capabilities of srsUE.

⚠ srsUE with slicing issue

AMF rejected: [gmm] ERROR: Non cleartext IEs is included [0xc] (../src/amf/gmm-handler.c:116) Described in Open5GS issue #958:

Open5GS AMF will follow the following policy to enhance security. If UE does not use a NAS container for Non-cleartext IEs, Open5GS AMF will send Registration reject message. If UE sends Non-cleartext IEs without Integrity-protected, Open5GS AMF will send Registration reject message. If UE does not send NAS container in Security mode complete message, Open5GS AMF will send Registration reject message.

There is a bug in srsRAN_4G UE, see issue srsRAN_Project/issues/165:

When added the slicing section to ue_zmq.yaml, srsue created an InitialUEMessage appended NSSAI to the Plain NAS 5GS Message, and sent it to AMF. On the other hand, according to the specification below, NSSAI is not specified to be included in cleartext IE.

📝Note for future optimization. There is SRSRAN Project Docker where docker-compose deployment to build and launch the gnb along with an all-in-one Docker container for Open5GS. There is Dockerfile. But there is no UE. Optinally you can use pre-built image also docker pull rohankharade/srsran:zmq. It is dramatically less in size and fresh, last pushed at Aug 2, 2023 at 11:50 am
